Best quality sinking winder made in China

Products Features:
JZ Series Shaft Sinking Winch is applied to overhang like scaffold ,water pump
,water pipe, grouting pipe, wind-cone, etc. during sinking operation on
vertical shaft of coal ,metal and nonmetallic mine.
Also this series winch can replace the construction winch to lift and carry
material during construction.
This series winches are designed on the basis of the regulation of overhanging
equipment during sinking operation.
USES: mainly used in coal mine, ore, non-metallic tunneling engineering of the
borehole vertical suspension Diao Pan, water pump,, hair dryers, compressed air
cylinder, grouting pipe etc tunneling equipment and tension on the rope, could
also be other underground and ground hoisting up heavy use.

Shaft sinking winders meet strict national standard. Among them, most important

1.The brake system should be dependable and accurate. The safety brake on the
drum and the working brake on the motor-gear coupler each have a minimum brake
torque no less than 2 times of the maximum working torque generated by the
maximum load. ( If your country requires higher brake torque than 2 times,
please indicate it in your enquiry.)
2.Main shaft material yielding strength is no less than 370MPa, the final
tensile strength is no less than 630MPa. The material is 45# steel, equivalent
of ASTM-A29/A29-04 1045 steel. All forged and heat treated. All main shafts of
winders must gone through ultrasound NDT.
3.Winders work at –25 ~ 400C. With proper gear oil, it can go –40 ~ 500C.
4.All exposed rotating parts have protective shields installed.
5.The running is smooth, no cyclic noises, the total noise level is lower than
6.All winders are tested under strict standard and quality certification paper
to be issued before it goes out.
7.Working brake and safety brake are tested by hoisting the rated load at test
8.5T, 10T, 16T, 25T and 40T models available. Single or double drums
9.Multiple brakes: main elec-hydraulic brake on drum; elec-hydraulic brake on
speed reducer shaft coupler ; worm gear reducer also have braking function.
