Principle structure wire rope hoist

electric wire rope hoists, everybody knows it's security is much better in   comparison with chain hoists. This principle is inseparable from its structure,   of which one of the wire rope hoist have its unique characteristics.Reducer: using three fixed helical gear rotating mechanism, the gear and the   gear shaft of heat-treated alloy steel box, ...cover made of high quality cast   iron, fitted tightly sealed. Reducer self-contained unit, loading and unloading   is very convenient. Control box: use can cut off the main circuit in case of   emergency, and up and down stroke protection off the fire stopper with means.   Ensure the safe operation of the hoist. Electric long component life and   reliable use. Rope: the GB1102-74 (6 * 37 + 1) X-type lifting cables, which   guarantees durability. metallurgical electric hoist Cone Line Motor: Lifting   motor with large starting torque tapered rotor brake asynchronous motor, no   external brake. 25% duty cycle motors, motor with Class B or Class F insulation,   electrical protection class IP44 / IP54. Button switch: Hand operating   lightweight and flexible, sub-corded and wireless remote manipulation of two   ways.

Crane classification

electromagnet overhead crane in bridge engineering used in lifting machinery, depending on its construction and performance, and can be divided into small light lifting equipment, bridge type crane and jib crane type three categories. Small light lifting equipment such as: Jacks, pneumatic hoists, electric hoists, balancing gourd (aka balance suspended), winches, etc.. Bridge type crane as beam cranes, gantry cranes. Such as fixed jib type crane slewing cranes, tower cranes, truck cranes, tire cranes, wall mount jib crane. Within a certain range vertical lifting and carrying heavy loads of horizontal multi-action lifting machinery. Also known as crane. It belongs to the material handling machinery. Working characteristics of the crane is doing intermittent movement, that in a work cycle Reclaimer, transport, unloading and other movements of the respective agencies are working alternately
