THKWJD-1 Underground Electric Loader is completely developed by our R&D staff, it is a new underground diesel loader, compare with the original loader, the features as below::
1.
A. The original loader adopts two rear wheels in the swing rack in order to solve the rough road, while the whole machine because of the road id too rough, shaking force and turbulence force are acting in the rear swing rack. As a result the swing rack is broken easily. Besides, during the loading it is easily to make the second gear or the third gear working harder, and also greatly reduce the shovel force. So the bucket loading is often overloaded and the oil temperature is quickly raised.
B. The new HKWJD-1 loader adopts rear body swing, and the whole rear swing angle is ±8°(according to your needs to adjust).That ensure the four wheels can contact with the ground, greatly increase the shovel force and reduce the failure rate.
2.
Running System adopts full hydraulic controlA. The original loader’s running system adopts mechanically control, two foot control board and through operation to connect the pole in order to control the pump forward and back. Because of the pull pole adopts a few parts to articulate, the results as flows: A. It is difficult to adjust the front and rear direction. B. Because of the articulated is easily worn, and accumulated error, finally the pump swash plate can not reach the max. Angle.
B. The new HKWJD-1 loader adopts full hydraulic control, the foot valve control hydraulic valve to make the forward and back operations. No matter what the circumstances, the pump swash plate can reach the Max. Angle, achieve the max. Shovel force and easily operation.
3.
Comparison of working system:
A. The original loader adopts manual operation poles, to pull the spool of multi-direction control valve make the actions of fall, lift, tipping, return. Due to the underground mine bad situation, multi-direction control valve be precise .If the fall thing on the valve spool, it will cause strain .And the valve be broken frequently.
B. The new HKWJD-1 loader adopts pilot hydraulic control, only the hydraulic pipe is outside. So it makes the operation more easier, simple and high efficiency. The whole working system adopts Vickers technological produced triple pump instead of original single pump and double pump system.
4.
Comparison of cable system:
The original loader adopts three pieces of overflow valve to limit the pressure, and great random of pressure regulating which always break down. While the new HKWJD-1 Loader adopts hydraulic control cable valve, forward and reverse of foot valve separately filling the oil, so the cable system is very safe and reliable, also low failure rate.
5
New Parking Brake:
The new HKWJD-1 loader is parking brake, and adopts transmission case drive the disc brake. Spring brake. hydraulically released brake .And the brake is full closed, the underground mine situation has no effect on it, so safety and reliability. The working brake adopts accumulator emergency brake, high efficiency. Even on 20° slope can be full loaded, good reliability.
6.
The bucket adopts V type structure, and the front blade adopts special anti-wear steal, reduces the resistance of picking shovel and increase the working life.
7.
The new HKWJD-1 loader adopts 16 Mn alloy steal. After finished process then through 24 hours tempering, relieving of internal stress to ensure the machine non-deforming. After tempering, it adopts blast sanding and don’t drop paint.
