9-20 meters 5 tons 380v industrial plant wire rope indoor electric hoist
Electric hoist is a special kind of lifting equipment installed on overhead cranes and gantry cranes. Electric hoists have the characteristics of small size, light weight, simple operation and convenient use. They are used in industrial and mining enterprises, storage, docks and other places.
The lifting weight is generally 0.3 to 80 tons, and the lifting height is 3 to 30 meters. It consists of a motor, a transmission mechanism and a drum or sprocket, and is divided into two types: wire rope electric hoist and chain electric hoist. Among them, electric chain hoists are divided into two types: imported and domestic; wire rope electric hoists are divided into single-speed hoisting and double-speed hoisting; miniature electric hoists, hoists, and multi-functional hoists.
Reducer, hoisting motor, running motor, flame breaker, cable sliding line, reel device, hook device, coupling, flexible cable current introducer, etc. integrate power and braking force.
Lifting weight: 0.25t-80t
Lifting height: 3m-30m
Working level: M3, M4
Running speed: 20(30)m/min
Lifting speed: 8m/min
Install and use
Electric hoists are generally installed on single girder cranes, bridge cranes, gantry cranes, and suspension cranes. With a little modification, it can also be used as a hoist. Therefore, it is an essential machine to improve labor efficiency and improve labor conditions.
Operating conditions
Ambient temperature: -20℃～+40℃
Work system: Intermediate JC25%
Heavy: JC40%
When the lifting capacity of the electric hoist of the intermediate working system is reduced by 30%, it is the electric hoist of the heavy working system JC40%.
Heavy duty working system JC40% electric hoist is used for heavy work, and the load is often in the case of rated value or high safety factor.
Electric hoist structure reducer: It adopts a three-stage fixed-axis helical gear rotating mechanism. The gear and gear shaft are made of heat-treated alloy steel. The box body and box cover are made of high-quality cast iron, with tight assembly and good sealing. The reducer is a self-contained part, and it is extremely convenient to install and remove.
Control box: It adopts a device that can cut off the main circuit in an emergency, and has a device with a fire stopper for protection of the upper and lower strokes. To ensure the safe operation of the electric hoist. Electrical components have long life and reliable use.
Wire ropes: Hoisting wire ropes include phosphating coated wire ropes, galvanized wire ropes and stainless steel wire ropes. The current national standard GB/T5972-1986 "Practical Specifications for Inspection and Scrap of Wire Ropes for Hoisting Machinery" is implemented to ensure durability.
Conical motor: The hoisting motor adopts a large starting torque conical rotor to brake the asynchronous motor, and no external brake is required. The motor load duration rate is 25%, the motor adopts Class B or Class F insulation, and the motor protection grade is IP44/IP54.
Button switch: Hand operation is light and flexible, and there are two ways: rope operation and wireless remote control.
