Working Engine 

CAUTION 

If power system and steering system of the loader still works with a working engine, the 

loader may be towed for a small distance to get out of muddy road or to the roadside. 

The operator of machine being towed must steer in the direction indicated by towing line. 

Make sure that loader is towed in strict accordance to instructions provided in this part. 

 

Shut-Down Engine 

Go through the following procedure before towing a loader with a shut-down engine: 

1． Connect piston chamber and dedicated hose in the same turning cylinder to allow free 

movement of turning cylinder. 

CAUTION 

Make sure that cylinder hose is properly connected before operating the loader. In case 

the hose is connected in reverse direction, steering system will not work. 

2． In case a failure of gearbox or transmission system possibly occurs, dismount driving axle 

split shaft. 

Refer to service manual for information on mounting and dismounting of driving axle split shaft. 

WARNING 

Loader will lose its parking brake when driving axle split shaft is dismounted, and the 

slippage of loader may cause personal injury or death. 

Wedge all tires to prevent the loader from moving. 

Trailer must be firmly connected, or the loader must be towed by two trailers in the same 

size as or larger size than the loader to be towed. In this case, both trailers should be 

connected with the loader, one in the front and the other in the back. 

Make sure that all repairs and adjustments are done before a serviced loader is reused. 

3． Release parking brake. 

4． Firmly apply towing lever. 

Remove tire wedges and tow the loader slowly at a speed no higher than 2km/h.

All the above parameters are measured on a loader horizontally parked on hard supporting ground. The 

operator should pay attention in operation to limits of various operating conditions, such as soft ground, slope 

or unbalanced carrying, and correspondingly adopt proper operating mode. 

1.3 Scope of Work and Configuration 

As one of major construction machines, loader is widely used in bucketing, conveying, unloading and 

leveling operation of loose materials in addition to light-duty cutting. 

The working unit of the loader is independently designed and developed by Chenggong with a self-made 

standard bucket. Loading weight of the loader should not exceed 5 tons. 

The loader is equipped with QSB series engine manufactured by Cummins Engine Company, Ltd. 

Torque-converting gearbox is ZF4WG200 manufactured by ZF Liuzhou Company. 

Front and rear driving axles are manufactured by Chenggong.
