Working Principle of Crawler CraneTrack Undercarriage

When the equipment working, the jib will be installed on boom, the arm and the boom into a certain angle. The hoisting mechanism has main and auxiliary two hoisting winch systems, the main hoisting system is used for the boom hoisting, and the auxiliary winch system is used for the auxiliary boom. And then through the internal with low-speed high-torque hydraulic motor running reducer, with high through performance. The basic body is through the "convex" shaped walking frame, high structural strength, rigidity. And then use the bending process, making the bottom roller, guide wheel(idler) and other key components using deep groove ball bearings, one-time plus butter lubrication, which can be exempted from the use of maintenance and servicing, . And double sealed structure, of refuel shaft end can prevent the mud into the wheel chamber.

Structure of Crawler Crane Undercarriage

Track Shoe(track pad, track plate), Sprocket(drive tumbler), Idler, Track Roller(bottom roller, lower roller), Top Roller(carrier roller, Upper Roller) Travel Motor, reduction gearbox, adjuster tension device, Crawler walking frame

Crawler Crane Undercarriage Track performance characteristics:

 With the function of Support the host weight, forward, backward, turn and walking.
 The steel track chassis uses construction machinery type which be made by Japan technical, has advantages in load capacity, big traction, small pressure and low noise,
 The chassis is equipped with planetary gearbox and plug-in hydraulic motor, with high performance.
 Shaped walking frame, structural strength, higher rigidity, the use of bending processing.
 Support wheel, guide wheel with deep groove ball bearings, one-time add lubrication butter, free maintenance and refueling service.
 Shaft end with double seal structure, to ensure that the oil seal is not leakage, and to prevent mud into the wheel chamber.
 Bottom Roller, idler roller and sprocket use alloy steel and quenched, good wear resistance, long service life.
 Spring tension device adjusted by color screw, so have high reliability
 The track support surface is large and the stability is good.
 Steel track with high rigidity and strength, good wear resistance, can work well in the rugged, harsh environment.

Safety indicators:
1, The connector components no loosening.
2, Wire rope and connecting parts meet the requirements.
3, The safety protection device and the instructions instrument complete and well.
4, Fuel, lubricants, hydraulic oil, cooling water, etc. to add sufficient.
5, should be walked and parked and operated on the .flat and solid ground
6. the slope shall not be greater than 3 °in the normal operation, and maintain a safe distance with the ditch and pit.
