Electric Dispatching Winch Components

The dispatching winch consists of eleven major parts: shunting and delivery, shunting iron bull, heavy hammer, heavy hammer bracket, pulley part, bracket parts, idler, guide wheel, tight rope device, and electric control part.

1. Dispatching winch - host

Commonly known as reducer, this reducer is a non-standard reducer designed and developed by coal itself. It has its own distinctive features: double output shaft, four-wheel friction, and four wheels rotate at the same speed in the same direction. The reducer shell is welded by steel plate, the first-order rotation adopts the arc-cone rack, and the rest are rotated by the spur gear. Gear material adopts 20CrMoTi, ZG40Cr, 17CrNiMo6, after quenching, carburizing, nitriding process, the normal service life can reach 5-10 years (except for wearing parts)

2. Tuning the car

Our company's iron cattle: cast, welded (track-changing, curved rail); gauges 900 and 1435 correspond to the passing railway and the end of the railway. The hook head configuration is based on C60, which fully considers the docking with the C70 wagon. (orbital track)

3. Heavy hammer

The weight is improved from the original round gray iron piece to a square steel piece, saving 210 USD / ton, and finally improved to welded filler parts, saving another 140 USD / ton.

4. Roller

For the use of tow ropes, the original gray iron parts are changed to nylon parts to save costs, the weight is saved by 60%, the transportation cost is saved accordingly, and the service life is extended by 100%. It is improved from the monolithic to the split type (70) and the hardness is increased by the quenching, but the cost is also increased.

5. Block, bracket, guide wheel:

Rotating parts, but low speed, copper sleeve structure, lubrication problems should be noted. If the lubrication is changed to a bearing structure, the lubrication effect can be improved, but the cost will increase.

6. Electronic control part

It can realize the low speed positive reversal of the winch and the high speed reversal of the empty car (PLC+ inverter + touch screen). The price difference between the two types is large.
