Leedem offers two models of shaft sinking winders (stage wind-ers) - SW and 2SW for single drum and double drum shaft sink-ing winders. They are made for hanging and moving galloways, cactus grabs, concrete forms, pumps, water and air pipes, vent tubing during shaft sinking process or other heavy-duty lifting applications above ground. They are widely used in coal mines, metal and non-metal mines. Both models have maximum load capacity of 5, 10, 16, 25, and 40 tons available.

Features and Benefits• Each model has multiple brakes: main elec-hydraulic brake

on drum; elec-hydraulic brake on speed reducer shaft cou-pler; worm gear reducer also offers braking function.

• All models can be equipped with hydraulic disc brakes or hydraulic band brakes.

• Heavy duty worm gear speed reducer. Heavy duty and pre-cisely made frame.

Leedem’s shaft sinking winders meet stringent technical requirements and national standards of many major min-ing countries. Here are a few samples:• The brake system is dependable and accurate. The

safety brake on the drum and the working brake on the motor-gear coupler each has a minimum brake torque no less than 3 times of the maximum working torque generated by the maximum load.

• Main shaft material yielding strength is no less than 370MPa, the final tensile strength is no less than630MPa. The material is 45# steel, equivalent to ASTM-A29/A29-04 1045 steel. All forged and heat treated. All main shafts of winders must go through ul-trasound NDT.

• Winders work at –25 ~ 400C. With proper gear oil, the range can extent to –40 ~ 500C.

• All exposed rotating parts are covered protective shields.

• Smooth operations, with no cyclic noises. The total noise level is lower than 85dB(A).

• All winders are tested under strict standard and come withqualitycertification.

• Working brake and safety brake are tested by hoisting the rated load at test tower.
