6–40 Ton Custom Heavy Duty Steel Crawler Undercarriage for Engineering Machinery

MAGEON provides custom heavy-duty steel crawler undercarriage solutions covering 6 to 40 ton load range. Built with premium manganese steel material and engineered for harsh field working conditions, these track undercarriage assemblies deliver exceptional load capacity, durability and terrain adaptability. They serve as reliable travel bases for excavators, bulldozers, rotary drilling rigs and other heavy engineering equipment.

Core Technical Specifications

MAGEON steel track undercarriage covers multiple tonnage specifications with mature standard configurations. Core parameters are as follows:

Working Principle

The track traveling mechanism is widely used in field operation vehicles such as construction machinery and tractors. The track contacts the ground while the drive sprocket does not contact the ground.

When the motor drives the drive sprocket to rotate, the sprocket continuously winds the track from the rear through the meshing between the sprocket teeth and the track chain under the driving torque of the reducer. The ground-contacting part of the track exerts a backward force on the ground, and the ground correspondingly gives the track a forward reaction force, which is the driving force pushing the machine forward. When the driving force is sufficient to overcome the traveling resistance, the track rollers roll forward on the upper surface of the track, thus driving the machine forward. The front and rear tracks of the whole machine can be steered independently, resulting in a smaller turning radius.

Core Features & Advantages

1、Load-Bearing & Travel Function

It fully supports the weight of the host equipment and realizes forward, reverse and steering travel functions, providing a stable travel foundation for various upper working devices.

2、High-Strength Steel Track

The steel track is made of high-strength manganese steel, with large load capacity and strong traction, low operation noise, and will not damage asphalt pavement under reasonable use, delivering excellent traveling performance.

3、Built-in Low-Speed High-Torque Reducer

Equipped with a built-in low-speed high-torque motor travel reducer, it delivers excellent terrain passability and strong climbing ability, maintaining stable power output under heavy load conditions.

4、High-Rigidity Formed Frame

The bent formed frame features high structural strength and rigidity. Processed by precision bending technology, it has strong torsion resistance and can cope with the impact of complex terrain.

5、Maintenance-Free Roller Design

Track rollers and idlers adopt deep groove ball bearings with one-time grease lubrication, which eliminates the need for maintenance and refueling during use, reducing daily maintenance workload.

6、Double Sealing Structure

The double sealing structure at the shaft end effectively prevents lubricating oil leakage, and can block mud and water from entering the wheel cavity, extending the service life of rotating parts.

7、Quenched Wear-Resistant Components

The teeth of track rollers, idlers and drive sprockets are made of alloy steel and treated by quenching process, with good wear resistance and long service life.

8、Adjustable Tensioning Mechanism

The spring tensioning mechanism adjusts the track to an appropriate tightness, improves the adaptability of engineering machinery to different road surfaces during travel, and enhances operation reliability and safety.

Frequently Asked Questions

Q: What tonnage ranges of steel crawler undercarriage do you provide?

A: We provide standard products covering 6t, 8t, 12t, 15t, 20t, 30t and 40t, and also support customized design for special tonnage requirements, which can be fully adjusted according to the customer's equipment weight and load demand.

Q: What material is the track shoe made of?

A: The track shoes are made of high-strength manganese steel, which has excellent wear resistance and impact resistance, and can maintain stable performance under long-term heavy load and gravel friction conditions, with a service life significantly better than ordinary steel products.

Q: What does "maintenance-free roller" mean?

A: Track rollers and idlers adopt deep groove ball bearings, which are filled with grease at one time before leaving the factory. No regular refueling maintenance is required during use. With a double sealing structure, it can effectively prevent mud and water from entering and reduce daily maintenance costs.

Q: What is the working principle of the crawler travel mechanism?

A: The motor drives the drive sprocket to rotate, and the sprocket meshes with the track chain to continuously wind the track. The ground reaction force on the track forms the driving force to push the machine forward. The left and right tracks can be independently steered, achieving a small turning radius and flexible maneuverability.

Q: Can I choose rubber tracks for this series of chassis?

A: Yes. We support both steel track and rubber track configurations. Customers can choose according to the working ground and operation requirements. Steel tracks are suitable for heavy load and harsh working conditions, while rubber tracks have better ground protection and low noise performance.

Q: What information do I need to provide for customizing a chassis?

A: You need to provide: operation site and working conditions, type of matching machinery, track material preference (steel or rubber), and total weight of the equipment. The more detailed the parameters, the higher the matching degree of the customized scheme.

Q: What is the advantage of the spring tensioning mechanism?

A: The spring tensioning mechanism can automatically adjust the tightness of the track, adapt to different road conditions, reduce the risk of track derailment, improve the stability of equipment traveling, and reduce the wear of track parts at the same time.

Q: What is the delivery cycle of standard tonnage chassis?

A: For standard tonnage products, the delivery can be arranged within 10 days under normal stock conditions. For customized products, the cycle will be determined according to the customization complexity, and we will provide a clear schedule at the demand confirmation stage.

Q: Is the frame made by bending process? What are the advantages?

A: The frame adopts precision bending forming process, with high structural strength and rigidity, strong torsion resistance, and can withstand the impact of complex terrain. Compared with simple welded frames, it has better structural consistency and longer fatigue life.

Q: What heat treatment is used for the rollers and sprockets?

A: The teeth of track rollers, idlers and drive sprockets are made of alloy steel and treated by quenching process, which significantly improves surface hardness and wear resistance, effectively extends service life and adapts to long-term heavy-load operation.
