Crawler Undercarriages

Crawler Undercarriages is an important part of the machine, which plays a supporting and walking role for the whole device. It is composed of walking motor, crawler assembly, walking frame, drive wheel, guide wheel, support heavy wheel, sprocket wheel, tightening mechanism and so on. It has the characteristics of high power, small grounding than pressure and good passage. Widely used in excavator, crawler crane, heading machine etc.

- Suitable excavators: 7.5 ~36 Tons

- Moving motor: KYB(Japan)

- Weight: 4 ~ 18 Tons

- Chains on pontoon : 2 rows

Main features:

1, This crawler undercarriage is specially designed and manufactured for small equipment, easily change large equipment to small equipment
2, The crawler undercarriage use low speed and high torque motor, the driving force is bigger
3, the crawler track and the chain plate are fixed with screw for maintenance convenience
4, Crawler undercarriage is equipped with mechanical brake,will not slip away in the rampway.
5, Crossbeam flange connection, easily disassembly and assembly.

Pontoons :they are allowed to be used in brackish water without affecting the pontoon's structural integrity. The pontoon bottoms are also reinforced for rough terrain operation. In each pontoon, we make 3 independent watertight compartments ensuring pontoon buoyancy and safety.

Track shoes : they are strong enough to support the whole amphibious excavator. Also, the wide and thick track shoes could help the amphibious excavator walking ( floating and swimming in water) faster in deep water.

Track chains : --- We assemble 2 rows of chains on each pontoon, which are made of super durable titanium alloy and 40Cr special alloy. This high quality steel can guarantee long-life of chains.
