When I talk with customers about mobile crushing equipment, I usually start with one simple question: what kind of working conditions will the machine face every day?

That question matters more than it may seem. A crusher working beside a quarry with stable power is not facing the same situation as a contractor moving from one construction site to another. Some projects have reliable grid electricity. Others do not. Some need high output for long working hours, while others need a machine that can move with the project.

This is where I see the SP1213ITD crawler impact crushing plant (diesel-electric) becoming a practical option. It combines a crawler-mounted mobile design with a diesel-electric power system and an impact crushing unit. According to Sunward's published specifications, the SP1213ITD has a total weight of 63 tons, a processing capacity of 120-350 t/h, a maximum feeding size of 600 mm, a C.S.S. range of 15-200 mm, and transportation dimensions of 19,000 × 4,260 × 3,850 mm. Its published total working power is 315 kW.Sunward official product information

What I like about this type of machine is the flexibility of its power arrangement. Sunward lists two power methods for the SP1213ITD: external electricity and the equipped generator. That means the machine can be considered for projects where power conditions may change or where a fully fixed electrical setup is not practical.Sunward official SP1213ITD product page

At Ganglong Heavy Industry Technology (Hefei) Co., Ltd., we look at this kind of equipment from the complete project perspective. Our company was founded in 2013 and, together with Hefei Ganglong International Trade Co., Ltd., covers equipment R&D, manufacturing, testing, customization, sales, and international trade. Our business includes construction machinery, mining machinery, agricultural machinery, and matching attachments.

For overseas customers, our international trade team supports machinery projects across Asia, Africa, America, and other regions. So when we discuss a SP1213ITD diesel-electric crawler impact crusher, we are not only looking at the crushing unit. We also consider configuration, inspection, documents, payment, packing, shipping, and the working conditions at the customer's site.

1. What Is the SP1213ITD Crawler Impact Crushing Plant?

In simple words, the SP1213ITD is a mobile impact crusher built on a crawler chassis. It is designed to travel around a working area while processing material through an impact crushing system.

The word “crawler” is important here. Unlike a traditional stationary crushing plant, the machine is not tied to one permanent foundation. The tracked chassis gives the plant the ability to reposition itself around a project. That can be useful when the material source changes, when a quarry face moves, or when a contractor needs to process material at different locations.

The word “impact” describes the crushing method. Instead of simply squeezing material between two surfaces, the crusher uses a high-energy rotor to strike the material and break it down. The crushed material then continues through the crushing chamber until it reaches the required size range.

The word “diesel-electric” describes the power arrangement. Sunward states that the SP1213ITD can use external electricity or its equipped generator. This gives the machine two power methods and is one of the main differences between this model and the SP1213IE electric version.

For me, the interesting part is the combination of these three ideas. A crawler chassis provides mobility. An impact crusher provides material reduction and shaping. The diesel-electric system provides more flexibility when the site's power conditions are not always the same.

Sunward lists the SP1213ITD under its crawler crushing and screening equipment range. The manufacturer gives the machine a 120-350 t/h processing capacity and a 600 mm maximum feeding size. The published C.S.S. range is 15-200 mm.

Source: Sunward official SP1213ITD product page and Sunward AU product listing.

One point I always make clear to customers is that published capacity should not be treated as a guaranteed production number for every material. The real output depends on rock type, feed size, moisture, feed consistency, crusher setting, operator practice, and the equipment connected before and after the crusher.

2. How Does the SP1213ITD Work?

The working principle is easier to understand if we follow the material through the machine.

Step 1: Material Feeding

Raw material enters the plant through the feeding system. The material may come from quarry blasting, demolition, mining, road construction, excavation, or another crushing stage.

The first goal is stable feeding. If the feed is irregular, the crusher may receive a sudden large load followed by an empty period. Neither situation is ideal. A steady material flow helps the crushing chamber work in a more predictable way.

For this reason, I do not look at the crusher alone when discussing a complete crushing line. The feeder, upstream crusher, screening equipment, conveyor system, and stockpile arrangement all influence the final production process.

Step 2: Impact Crushing

After entering the crusher, the material meets the rotating impact rotor. The rotor carries high kinetic energy and transfers that energy into the material.

Sunward describes the SP1213ITD impact crusher as using a large kinetic-energy and heavy-rotor design. The manufacturer says this design is intended to provide a high crushing ratio, large output, and good particle shape.

In plain language, the rotor hits the material hard enough to break it into smaller pieces. The material may also hit internal impact surfaces, creating further size reduction.

This crushing method is particularly useful when the shape of the final aggregate matters. In many applications, customers do not simply want smaller rocks. They want material with a usable particle shape and a controlled size range.

Step 3: Size Control

The C.S.S. range published for the SP1213ITD is 15-200 mm. C.S.S., or closed-side setting, is a common crusher measurement related to the discharge opening.

A smaller setting generally means a smaller product, while a larger setting allows larger material to pass through. But I would not use the setting alone to predict final product gradation. Feed size, material properties, rotor speed, feed rate, and crusher condition all play a role.

Step 4: Conveying

Once the material has been crushed, it moves through the conveyor system and can be transferred to stockpiles or additional processing equipment.

In a complete crushing and screening line, the crushed material may go directly to a screening plant. Oversized material can then be returned for another crushing stage, depending on the plant layout and required product sizes.

This is where the mobile concept becomes useful. The crusher and other equipment can be arranged around the actual worksite instead of forcing the material to travel long distances to a permanent processing point.

3. Main Features of the SP1213ITD I Would Pay Attention To

When I evaluate a crawler impact crushing plant, I do not focus on one impressive-looking specification. I want to know how the individual features work together in a real job.

Two Power Methods

The most obvious feature of the SP1213ITD is its diesel-electric arrangement.

Sunward states that the machine supports two power methods: external electricity and the equipped generator. The manufacturer describes this as convenient and energy-saving.

For a project with stable grid electricity, external power may be used. When external electricity is unavailable or unsuitable, the generator provides another operating option.

This matters for mobile crushing because not every quarry, mine, construction project, or infrastructure site has the same electrical infrastructure.

Before ordering, I would still check the site's actual electrical conditions, local regulations, generator requirements, fuel arrangements, working hours, and environmental rules. A flexible power system is useful only when it matches the project.

Heavy Rotor and High Kinetic Energy

The impact crusher uses a heavy rotor design. Sunward connects this design with high crushing ratio, large output, and good particle shape.

The basic idea is simple: a heavier, properly designed rotor can transfer significant energy into the crushing process. That energy helps break incoming material and maintain the crushing action under suitable operating conditions.

For customers, I would pay attention not only to the rotor itself but also to wear parts, maintenance access, material characteristics, and the expected working hours. Abrasive materials can place very different demands on an impact crusher compared with softer materials.

Integrated Variable Frequency System

Another important feature is the integrated variable frequency system. Sunward states that the system includes dust-proof, cooling, vibration-isolation, and water-proof functions to protect the electrical system.

For people who are not used to electrical equipment, variable frequency simply means that the electrical system can control motor operation in a more flexible way rather than treating the motor as a simple on-and-off device.

Protection is equally important on a crushing site. Dust, vibration, moisture, and heat are normal parts of this kind of working environment. The electrical system therefore needs appropriate protection.

Power for Combined Screening Equipment

Sunward also highlights the high-power engine's ability to provide power for a screening plant used in combination with the crusher.

This is useful when the customer wants a more complete mobile crushing and screening process rather than a crusher working alone.

A typical process may look like this:

• Raw material enters the crushing plant.

• The impact crusher reduces the material size.

• The crushed material moves to screening equipment.

• The screen separates different particle sizes.

• Oversized material may return to the crushing stage.

• Finished aggregate is sent to different stockpiles.

The exact layout depends on the material and required products, but this general arrangement is common in aggregate processing.

Professional Ergonomic Design

Large mobile crushers are not machines that operators can treat casually. There are moving parts, conveyors, electrical systems, crushing forces, and heavy components involved.

Sunward lists professional ergonomics design as one of the SP1213ITD product highlights.

From a practical point of view, good access, clear operating arrangements, maintenance space, and reasonable control layout all matter. When a machine needs regular inspection and maintenance, small design details can save a lot of time over the machine's working life.

4. SP1213ITD Technical Advantages and Model Comparison

When a customer asks me to compare two mobile crushing plants, I usually put the numbers side by side first. It removes a lot of confusion.

SP1213ITD vs. SP1213IE

The SP1213IE is the electric version of the same general crawler impact crushing platform. The SP1213ITD uses a diesel-electric power arrangement. Sunward's published data shows that the two machines have the same listed processing capacity, maximum feeding size, C.S.S. range, and transportation dimensions, while their drive systems, working power, and total weight differ.

Source: Sunward official SP1213ITD page and Sunward AU product listing for SP1213ITD and SP1213IE.

So how would I explain the difference to a buyer?

If the project has reliable external electricity and the customer wants an electric-only drive arrangement, the SP1213IE is the relevant configuration to investigate. If the project needs the option of external electricity and an onboard generator, the SP1213ITD provides that additional power flexibility.

Neither choice should be made from the model name alone. Site conditions should decide the configuration.

SP1213ITD vs. SP127JTD

Another useful comparison is between the impact crusher and a crawler jaw crushing plant. These machines do different jobs, so the numbers need to be understood in context.

Source: Sunward official SP1213ITD and SP127JTD product information.

A jaw crusher is commonly considered for primary crushing, especially when the incoming rock is large. An impact crusher can be used for further reduction and shaping, depending on the material and target product.

That is why I would not simply ask, “Which machine has the larger capacity?” The better question is, “Where will this machine sit in the crushing process?”

What the Numbers Really Tell Me

The SP1213ITD's published capacity of 120-350 t/h gives us a useful starting point. But capacity is affected by many variables.

For example, a clean and steady feed of suitable material can behave very differently from a mixed feed containing oversized pieces, sticky material, excessive moisture, or unwanted objects.

Likewise, a 15 mm C.S.S. setting should not be treated as an automatic promise that every particle will be exactly 15 mm. Crushing creates a range of particle sizes. The actual gradation must be checked against the customer's product specification.

5. Applications of the SP1213ITD Diesel-Electric Mobile Impact Crusher

The SP1213ITD is designed for mobile material processing, so I would normally look at applications where mobility and flexible power supply are useful.

Quarrying and Aggregate Production

Quarries are one of the most natural applications for a crawler impact crushing plant.

Rock extracted from a quarry often needs to be reduced and shaped into usable aggregate. Depending on the rock type and final product requirements, an impact crusher can be used as part of a multi-stage crushing process.

For example, a jaw crusher may handle the initial large feed, followed by an impact crusher for further reduction. Screening can then separate the material into different sizes.

The actual configuration should be based on the rock's hardness, abrasiveness, feed size, desired product size, and required output.

Mining

Mining sites often have changing working conditions and may not have convenient access to grid power. This is where the diesel-electric configuration can be useful to investigate.

The SP1213ITD has a published maximum feed size of 600 mm and a processing capacity of 120-350 t/h.

However, I would never recommend choosing the crusher for a mining application based only on those two numbers. Ore hardness, abrasiveness, density, moisture, feed distribution, operating hours, and required product size need to be considered together.

Road Construction

Road construction projects can move over large areas. The material processing point may change as the road section changes.

A crawler-mounted crushing plant can be useful in this type of environment because the crusher is not tied to one fixed foundation. The equipment can be repositioned within the working area as the project develops, subject to site access and operating requirements.

Construction and Demolition Material

Mobile impact crushing can also be considered for suitable construction and demolition materials.

Concrete and mineral-based demolition material can contain steel, wood, plastic, glass, and other unwanted objects. These materials should be sorted or removed before crushing where required.

I always remind customers that crushing and sorting are two different jobs. A powerful crusher cannot replace proper material preparation.

Infrastructure and General Earthmoving

Infrastructure projects often involve temporary material processing. Contractors may need to crush rock or suitable excavated material near the project instead of transporting everything to a distant stationary plant.

In these cases, mobility can become a major part of the equipment decision. If the project also has uncertain access to grid power, the diesel-electric configuration adds another point to consider.

6. Production, Inspection, Delivery and International Logistics

When I deal with heavy machinery orders, I always separate the equipment itself from the complete delivery process. A crusher can be technically suitable and still become a difficult project if the logistics and documentation are not planned properly.

Production Schedule

Production time depends on the confirmed model, machine configuration, order quantity, optional equipment, and customization requirements.

For that reason, we confirm the production schedule with the customer before production starts. This gives both sides a clear understanding of when the machine will be prepared for inspection and shipment.

For special configurations, the customer should provide requirements as early as possible. Changes made after production has started can affect the schedule and cost.

Pre-Shipment Inspection

Before shipment, the machine is inspected according to the confirmed order requirements. We pay attention to appearance, main functions, hydraulic and electrical systems where applicable, and basic operating performance.

For the SP1213ITD, the diesel-electric power arrangement deserves particular attention. The customer needs the delivered configuration to match the confirmed technical and commercial documents.

Standard documents and accessories are also prepared according to the order. If the customer requires manuals, certificates, spare parts, inspection records, or other documents, these requirements should be confirmed before shipment.

Payment

For international machinery transactions, T/T is commonly used. A typical arrangement may include a deposit before production and the balance before shipment.

The exact payment terms are not automatically the same for every order. They should be clearly confirmed between both parties before production begins.

I prefer this approach because heavy equipment involves a long chain of activities. Clear payment conditions make it easier to coordinate production, inspection, shipping, and documentation.

Sea Transportation

The SP1213ITD has a published transportation dimension of 19,000 × 4,260 × 3,850 mm and a total weight of 63 tons.

For overseas orders, sea transportation is generally the practical route for a complete machine of this size.

Before shipping, I would check:

• Destination port

• Available shipping route

• Machine dimensions and weight

• Loading and unloading arrangements

• Port handling requirements

• Customs documentation

• Final inland transportation

• Local road restrictions

The exact logistics plan depends on the customer's country and destination. We do not treat international shipping as a one-size-fits-all process.

Packaging and Protection

Heavy machinery needs practical protection rather than decorative packaging.

Machines are generally protected with suitable film or protective materials, fixed securely, and prepared according to shipping requirements. Spare parts and loose accessories can be packed separately in cartons or wooden cases.

The final packing arrangement can be adjusted according to the destination, shipping route, customer requirements, and shipping conditions.

7. Why Choose Ganglong for Your SP1213ITD Project?

There is a big difference between selling a machine and supporting a machinery project.

Our company, Ganglong Heavy Industry Technology (Hefei) Co., Ltd., was founded in 2013. Together with Hefei Ganglong International Trade Co., Ltd., we operate across equipment R&D, manufacturing, testing, customization, sales, and international trade.

We offer self-branded HKLOONG Excavators, loaders, Backhoe loaders, and swamp excavators. At the same time, our business includes complete machine sales and leasing services for domestic and international construction machinery brands, as well as construction machinery, mining machinery, agricultural machinery, and attachments.

This broad equipment background is useful when customers are planning a complete material handling or construction project. A crushing plant rarely works completely alone. There may be Excavators loading material, loaders handling stockpiles, screening equipment separating products, and trucks moving finished aggregate.

Our international trade arm, Hefei Ganglong International Trade Co., Ltd., focuses on overseas machinery business. The team has experience with construction machinery, mining machinery, and agricultural machinery and has served customers across Asia, Africa, America, and other regions.

When a customer contacts us about an SP1213ITD crawler impact crushing plant, I prefer to ask practical questions first.

• What material do you want to crush?

• What is the maximum feed size?

• What capacity do you need per hour?

• What final sizes do you need?

• Will the machine work as a primary or secondary crushing stage?

• Do you have reliable external electricity?

• Do you need the generator function regularly?

• Will a screening plant be connected to the crusher?

• Where will the machine operate?

• Which country and port will receive the machine?

These questions are not just sales questions. They help prevent a common problem in heavy machinery purchasing: buying a machine based on a specification sheet without checking whether the complete project can actually use it efficiently.

We can also discuss spare parts and accessories before shipment. For an overseas customer, it makes sense to think about maintenance items before the machine leaves the factory rather than waiting until the first urgent replacement is needed.
