JKMD Multi-rope Friction Hoist

Working Principle:

Friction hoist is the use of friction to transmit power, wire rope on the friction wheel of the friction village pad, lifting the container hanging in the ends of the wire rope, hanging at the bottom of the container balance wire rope, lifting the tensioned wire rope to a certain positive pressure pressed tightly on the friction wheel, the wire rope under the action of friction and friction wheel together, so as to achieve the lifting or lowering of the container, the series of hoist through the electrical drive to achieve speed regulation.

JKMD technical features

1、The spindle and hub are forged as a whole, and the hub and friction spokes are connected with high strength bolts.
2、Friction liner adopts high performance friction liner, with high friction coefficient and good wear resistance, absorbing the vibration energy of wire rope, preventing wire rope from twisting, not being wet, and strong corrosion resistance.
3、The friction wheel adopts all-welded structure, and the spokes adopt the whole spoke plate type.
4、The rolling bearing uses double-row radial spherical roller bearing, which allows micro-jumping around the center of the bearing to supplement the angular displacement brought about by the bending of the shaft force.
5、The low-speed shaft of planetary gear reducer adopts gear coupling, and the high-speed shaft adopts elastic bar pin coupling.
6、Brake adopts hydraulic cylinder rear disc brake, and each brake is equipped with brake tile wear switch and disc spring fatigue detection switch.
7、Low-speed DC motor is used, the stator is split type, the rotor is suspended type, directly connected with the end flange of the spindle, driving the work of the coil, which can eliminate the reducer, coupling and motor in the bearing seat and lubrication station, smooth transmission, low environmental noise.
8. DC electric control adopts thyristor-powered armature reverse mode, and selects the main wiring mode according to the system and motor capacity size, when the -group rectifier bridge fails, it can switch to full-load half-speed or half-load full-speed and other emergency operation independent dual-system hydraulic station. jkmd technical features

Features of direct link hoist
