hoist for coal mine

This hoists are used for lifting materials in various mine and transporting personnels.

The product is mainly used for various types of mine shafts to do to upgrade materials, transport personnel.

Features1, floor-standing Direct multi-rope friction hoist motor rotor and the elevator shaft using a direct connection sleeve, the motor rated speed is low, stable and hoist operation, maintenance, a small amount of construction and installation of wellhead is not occupied, can effectively shorten the duration of construction of wells .2, the first domestic use of permanent magnet synchronous motor, synchronous motor realized within the sine wave of electromotive force, eliminating the motor when the torque in the low frequency clock oscillator problem, high efficiency, small size, non-polluting.JKMD Technical Features:1, spindle and wheel hub for the whole forging, the friction wheel spokes with the use of high strength bolt connection.2, friction pads use high-performance friction pads, friction coefficient of high, good wear-resistance and absorb vibration energy wire rope to prevent the rope reversed, will not be soaked, and anti-corrosion resistance.3, friction wheel all-welded structure, and spoke with the overall plate convergence.4, use double row radial bearing spherical roller bearings, allowing micro-jump move around the bearing center to supplement the force due to shaft bending brought about by the angular displacement.5, planetary gear reducer with low-speed shaft gear couplings, high-speed shaft coupling elastic rod pin.6, the brake hydraulic cylinder rear-mounted disc brake, each brake wear are equipped with brake disc spring fatigue detection switches and switch.7, using low-speed DC motor, the stator for the split type, the rotor is suspended directly connected with the spindle end flange to drive the work rolls can be avoided reducer, even the device and the motor shaft in the bearing and lubrication points , transmission smooth, low noise environment.8, DC-controlled power supply using thyristor armature reverse manner and in accordance with the system and electrical wiring capacity of the size of the main selection, when a group of rectifier bridge failure can be switched to half-speed or full load half load speed and other emergency response Running an independent dual system hydraulic station.
