HX340HD crawler excavator for Heavy Construction and Earthmoving
When I talk with customers about a large crawler Excavator, I usually start with one simple question: what kind of work will the machine actually do? A Large Excavator is a serious investment, so looking only at engine power or bucket size is not enough. The machine needs to match the soil, working depth, transport conditions, attachments, project size, and expected working hours.
The HX340HD Crawler Excavator is designed for this type of demanding work. It is a large Hyundai crawler excavator with a published operating weight of around 33 tons, 193 kW rated power, and a 1.74 m³ bucket in the referenced specification. The machine is intended for heavy excavation, earthmoving, road construction, infrastructure projects, quarry support, mining-related work, and other applications where a medium excavator may simply be too small.
From my experience working with construction machinery buyers, the useful part of a product page is not just listing numbers. Customers want to know what those numbers mean when the excavator is actually working. Can it dig deep enough? Can it handle a large bucket? Is it stable? How does it move around the site? What happens before shipment? Can the supplier help with inspection and international transportation?
That is what I will cover here. I will explain the Hyundai HX340HD Crawler Excavator from a practical buyer's point of view, including its main specifications, working principle, strengths, applications, configuration considerations, inspection process, delivery arrangements, and frequently asked questions.
The HX340HD is a large crawler excavator built for heavy-duty working conditions. The “HD” configuration is especially relevant when customers are looking for a machine that can handle substantial excavation and material-moving work rather than light site maintenance.
The Hyundai official product information lists the HX340SL & HD family at approximately 33 tons operating weight, with a 193 kW engine rated at 2,200 rpm and a 1.74 m³ bucket capacity. The same published specification gives a Hyundai HM8.3 engine, maximum torque of 117 kgf·m at 1,300 rpm, two main pumps with a rated flow of 306 L/min each, and a 350 kgf/cm² implement circuit.
Another important point is that the HX340HD should not be treated as a one-size-fits-all machine. Hyundai's technical material shows that track shoe width, operating equipment, boom and arm configuration, and other options can change the final machine specification. For example, the published brochure lists 600 mm, 700 mm and 800 mm track shoe options, with different operating weights and ground pressures.
That is why I always recommend confirming the actual machine configuration before purchasing. The model name tells us the machine family, but the final quotation should identify the configuration being supplied.

For a contractor planning heavy excavation, this specification combination is worth looking at as a complete system. The engine, pumps, hydraulic cylinders, swing system, travel system, undercarriage and working equipment all need to work together. A single impressive number cannot tell the whole story.
The basic working principle of the HX340HD is straightforward. The engine produces power, the hydraulic system converts that power into controlled movement, and the boom, arm and bucket use that hydraulic force to cut into the ground, lift material and place it where it needs to go.
When the operator moves the controls, hydraulic oil is directed to the relevant cylinders or motors. The boom can be raised and lowered. The arm moves in and out. The bucket opens and closes. The upper structure can swing, while the crawler undercarriage provides travel movement.
It sounds simple, but the balance between these systems is what makes a large excavator useful. The operator is constantly combining several movements. For example, when loading a dump truck, the machine digs into the pile, pulls the bucket toward the machine, lifts the boom, swings the upper structure, positions the bucket over the truck and releases the material.
The HX340HD uses a hydraulic system with two main pumps, each rated at 306 L/min in Hyundai's published specification. The machine also has a dedicated pilot circuit and hydraulic travel and swing motors.
The crawler system is equally important. A machine weighing around 33 tons needs a stable base. Tracks spread the machine's weight over a larger contact area than ordinary wheels. This helps the excavator maintain a solid working position while digging, swinging and handling loaded buckets.
The published HX340HD data lists a maximum traction force of 29,500 kgf and maximum gradeability of 35 degrees. Travel speed is listed at up to 6.4 km/h, with a lower travel speed available for different operating conditions.
I would not expect a crawler excavator to move around a public road like a Wheeled Excavator. That is not its purpose. Its strength is staying on the jobsite and doing heavy work from a stable tracked platform.
One of the first things I notice about the HX340HD is its size. Hyundai publishes an operating weight of approximately 33 tons for the HX340SL & HD specification.
This puts the machine into a class where stability and working capacity become important. When an excavator is digging a deep trench or swinging a loaded bucket, the operator needs a machine that feels planted rather than light.
Of course, more weight also means more attention must be paid to transportation. Before ordering, I recommend confirming the machine's exact operating weight, overall dimensions, track width, shipping method and destination port.
The referenced Hyundai specification gives the HX340HD a rated power of 193 kW at 2,200 rpm. The engine is identified as the Hyundai HM8.3. Hyundai's technical brochure for the HX340HD gives a closely related figure of 194 kW gross power and 190 kW net power, showing why customers should check whether a quotation is using gross or net power.
This is a good example of why I prefer to compare complete specifications rather than copy one number from different sources. When a customer asks for engine power, I also confirm the measurement standard and exact machine version.
The published HX340HD bucket capacity is 1.74 m³. The official brochure identifies the bucket as a high-strength steel bucket and provides a bucket selection guide for different working conditions.
Bucket selection is more important than many first-time buyers expect. A large bucket is useful for moving loose material quickly, but hard or abrasive materials may require a different bucket design. If the machine is intended for rock or quarry work, I recommend discussing the material density and attachment requirements before confirming the order.
The HX340HD technical brochure lists bucket digging force at 216.7 kN under ISO conditions, increasing to 235.3 kN with the applicable boost setting. Arm crowd force is listed at 145.1 kN under ISO conditions, with a boosted value of 157.6 kN.
These figures help explain why the machine is suitable for heavy excavation. In simple terms, the hydraulic system provides the force needed to push the bucket into the ground and pull material toward the machine.
The standard published configuration uses a 6,450 mm boom and 3,200 mm arm. Maximum digging reach is listed at 11,150 mm, maximum digging depth at 7,360 mm, maximum digging height at 10,360 mm, and maximum dumping height at 7,260 mm.
This working range is useful for deep excavation, foundation work, drainage projects, truck loading and large-scale site preparation.
When customers compare large Excavators, I prefer using published numbers. At the same time, I make it clear that a comparison table does not automatically tell us which machine is right for a specific job.
For example, Hyundai's current product information lists an HX340SL & HD configuration at 33 tons and 193 kW, while another Hyundai market listing for the HX340SL & HD family shows a 30.0-ton machine with 184 kW.
This difference is exactly why the customer should confirm the destination market and actual configuration before making a purchase decision.
| Model / Specification | Operating Weight | Rated Power | Bucket Capacity |
|---|---|---|---|
| HX300HD | 30.2 tons | 193 kW / 2,200 rpm | 1.50 m³ |
| HX340HD | 33 tons | 193 kW / 2,200 rpm | 1.74 m³ |
| HX350L | 33.15 tons | 208 kW / 2,200 rpm | 1.44 m³ |
| HX400L T3 | 39.32 tons | 208 kW / 2,000 rpm | 1.46–2.50 m³ |

The comparison shows that the HX340HD sits in a useful heavy excavator range. It is larger than the HX300HD in operating weight and bucket capacity, while remaining below the HX400L in overall machine class.
But there is another point worth mentioning. A customer looking at the HX340HD may see several specifications online that do not match exactly. That does not necessarily mean one source is wrong. Different markets, model years, emissions requirements and configurations can produce different published data.
| HX340HD Item | Published Value | Configuration Consideration |
|---|---|---|
| Operating weight | Approx. 33,000 kg | Can change with track shoe and equipment selection |
| Track shoe width | 600 / 700 / 800 mm | Wider shoes can change machine weight and ground pressure |
| Ground pressure | Approx. 0.64 / 0.55 / 0.49 kgf/cm² | Depends on track shoe configuration |
| Boom | 6,450 mm HD | Working range depends on boom and arm configuration |
| Arm | 3,200 mm | Attachment and working equipment affect final specification |
| Maximum digging reach | 11,150 mm | Published standard configuration |
| Maximum digging depth | 7,360 mm | Published standard configuration |

For me, this is one of the most important parts of buying heavy equipment. The exact configuration should be written clearly in the quotation so that the buyer, supplier, logistics company and final customer are all talking about the same machine.
Large earthmoving projects are probably the easiest application to understand. When a project involves large amounts of soil, the excavator needs enough bucket capacity, hydraulic force and working stability to keep the job moving.
The HX340HD can excavate soil, load trucks, create stockpiles and prepare large working areas. It can work together with dump trucks, Wheel loaders, bulldozers, graders and compactors as part of a larger earthmoving team.
Road construction involves much more than laying asphalt. Before the finished road appears, contractors may need to remove soil, prepare the roadbed, dig drainage channels, install pipes and move large quantities of material.
A 33-ton-class crawler excavator can support many of these operations. Its tracked undercarriage also makes it suitable for working directly on rough construction surfaces rather than relying on finished roads.
Large buildings, industrial plants, bridges, drainage systems and other infrastructure projects often require substantial excavation.
The HX340HD's published maximum digging depth of 7,360 mm and maximum digging reach of 11,150 mm provide useful working range for deep excavation and large site preparation tasks.
For foundation work, I would still check the actual excavation plan before recommending the machine. Soil conditions, trench dimensions, access, lifting requirements and surrounding structures can all affect machine selection.
The HX340HD can be considered for selected mining and quarry applications, especially excavation and material handling where the machine is matched with suitable working equipment.
However, quarry work can be very hard on buckets, teeth, undercarriage components and hydraulic attachments. If the customer is working with abrasive rock, I always ask about material density and hardness before discussing the bucket configuration.
Deep drainage channels and pipeline corridors are another practical application. The excavator can remove soil, shape trenches and load excavated material into trucks.
For these jobs, reach and control matter as much as raw power. The operator needs to place the bucket accurately without repeatedly moving the entire machine.
Large land-development projects often involve clearing, excavation, grading support and material movement. A crawler excavator can handle the heavy excavation stage while other machines complete grading and compaction.
For smaller landscaping projects, however, I would normally consider a smaller excavator. There is no point using a 33-ton machine where a compact machine can do the same job with less transport difficulty.
When customers buy construction equipment internationally, the machine itself is only one part of the transaction. I have seen buyers pay close attention to the excavator and then overlook shipping documents, inspection, accessories or packing requirements. That can create unnecessary trouble later.
At Ganglong Heavy Industry Technology (Hefei) Co., Ltd., our role is to provide construction machinery sourcing and international trade services. We were founded in 2013, and together with Hefei Ganglong International Trade Co., Ltd., we work with construction machinery, mining machinery, agricultural machinery and matching attachments.
We also have our own HKLOONG product range, while supplying and arranging complete machines from domestic and international brands including Hyundai, Hitachi, SANY, Lonking, XCMG, SHANMON and LOVOL.
For Hyundai equipment such as the HX340HD, we act as a supplier and trade service provider. We do not describe ourselves as the manufacturer of Hyundai machines. Our job is to help the customer source the required equipment and manage the related commercial and logistics process.
The delivery time depends on the exact HX340HD configuration, machine availability, order quantity and destination. If the machine is available, the process can be different from a factory production order. If a specific configuration needs to be arranged, the expected schedule must be confirmed before the order is finalized.
I prefer to confirm availability first rather than give a fixed delivery promise without checking the actual machine status.
Before shipment, we can arrange inspection according to the customer's confirmed requirements. The inspection may include the machine's exterior condition, engine, hydraulic system, electrical system, working functions, attachments, accessories and required documents.
For a used machine, the inspection can be expanded to include visible wear, track condition, hydraulic leakage, attachment condition and operating performance, depending on the agreed inspection scope.
The key point is simple: the inspection should describe the actual machine being shipped. A generic inspection sheet is not enough for a large international equipment transaction.
T/T is commonly used for international construction machinery transactions. A typical arrangement may include a deposit before order processing and the balance before shipment. The exact payment structure is confirmed between the two parties according to the machine, order and transaction conditions.
For international orders, a complete HX340HD crawler excavator is generally transported by sea. Because this is a large machine, shipping planning needs to consider the machine's dimensions, weight, port requirements and final destination.
Spare parts and suitable smaller accessories can normally be considered for air freight or express delivery when their size and weight allow it.
A crawler excavator is not packed in a conventional carton. Instead, the machine is securely positioned and protected for transportation. Loose parts, accessories and spare components can be packed separately in cartons or wooden cases.
Before shipment, we confirm the final packing and securing method according to the destination, carrier requirements and customer instructions.
I use the word “matching” very deliberately. A large excavator is not automatically the right excavator.
If the customer is digging large foundations, moving soil all day and loading multiple dump trucks, the HX340HD's size and working capacity can make sense. If the customer is working on narrow urban streets or small residential sites, the same machine may create unnecessary transport and space problems.
Before I discuss a final machine configuration, I normally want to know several things:
What material will the excavator dig?
What is the expected digging depth?
How much material needs to be moved each day?
Will the machine mainly excavate, load, grade or handle attachments?
What bucket capacity is suitable?
Does the project require a Hydraulic Breaker or another attachment?
What are the local transport restrictions?
What engine emission standard is required in the destination market?
Is the machine new, available from stock, or arranged according to order?
These questions may sound basic, but they prevent many expensive mistakes.
At Ganglong, our international trade team has served customers in Asia, Africa, America and other markets. Because we work with different categories of construction, mining and agricultural equipment, we understand that customers may need more than one machine or attachment.
For example, a road contractor may need an excavator together with buckets, breakers, loaders and dump trucks. A quarry customer may need an excavator with heavy-duty working equipment. A land-development contractor may need excavation equipment followed by grading and compaction machinery.
So when a customer asks me for an HX340HD for sale, I do not want to stop at the model name. I want to know what the machine needs to accomplish.
Once the requirements are clear, we can confirm the machine configuration, availability, attachments, inspection scope, commercial terms, packing and shipping arrangements.
Hyundai's published HX340SL & HD specification lists an operating weight of approximately 33 tons. The technical brochure also gives 33,000 kg for the HX340HD with the referenced track configuration. Final weight can change with track shoes and other equipment.
The current Hyundai product listing gives 193 kW at 2,200 rpm. The HX340HD brochure gives 194 kW gross power and 190 kW net power, so buyers should confirm whether a quotation is referring to gross or net engine power.
The referenced Hyundai specification identifies the engine as the Hyundai HM8.3. The brochure describes it as a six-cylinder, water-cooled, four-cycle, turbocharged and charge-air-cooled diesel engine with an 8.3-liter displacement.
The published HX340HD specification gives a 1.74 m³ bucket capacity. Hyundai's technical brochure also provides bucket selection information for different materials and working conditions.
The standard published working range lists a maximum digging depth of 7,360 mm and maximum digging reach of 11,150 mm. Actual working range can vary with boom, arm, bucket and other configuration choices.
The technical brochure lists an ISO bucket digging force of 216.7 kN, with a boosted value of 235.3 kN. ISO arm crowd force is listed at 145.1 kN, increasing to 157.6 kN with the applicable boost setting.
It can be considered for quarry and mining support applications when the machine is equipped appropriately. For hard or abrasive rock, I recommend confirming the bucket, teeth, attachment and duty requirements before purchase.
Yes. Its large operating class and working range make it suitable for many road construction tasks, including excavation, drainage, earthmoving, loading and site preparation.
Hyundai's published data lists a maximum travel speed of 6.4 km/h and a lower travel speed of approximately 3.6 km/h.
The published specification gives a maximum gradeability of 35 degrees. Actual safe operation depends on ground conditions, slope, load, operator practice and site safety requirements.
Complete machines are generally transported by sea for international orders. The final shipping method depends on machine dimensions, destination, port requirements and customer arrangements. Suitable spare parts and accessories may be shipped by air or express.
Yes. We can arrange a pre-shipment inspection according to the confirmed order. The inspection can cover the machine appearance, engine, hydraulic and electrical systems, working functions, attachments, accessories and documents.
No. Ganglong is a construction machinery supplier and international trade service provider. We can source and supply Hyundai equipment according to customer requirements, while Hyundai remains the original equipment brand.
When I look at the Hyundai HX340HD Crawler Excavator, I see a machine built around one basic idea: give heavy-duty contractors enough power, working range and stability to handle substantial excavation and earthmoving jobs.
The published 33-ton operating weight, 193 kW rated power, 1.74 m³ bucket capacity, dual 306 L/min main pumps, 11,150 mm maximum digging reach and 7,360 mm maximum digging depth show why this machine belongs in the large excavator class.
At the same time, I would not tell every customer to choose an HX340HD. Machine selection should always start with the job. If the project requires large-scale excavation, road construction, foundation work, drainage, earthmoving or selected quarry applications, this class of crawler excavator deserves serious consideration.
The final configuration is just as important as the model name. Track shoe width, bucket selection, boom and arm configuration, attachment requirements, engine specification, emissions requirements and transport conditions should all be confirmed before the order is placed.
