Electric wire rope hoist is a kind of special lifting equipment, installed in the crane, gantry crane, electric wire rope hoist has the advantages of small volume, light weight, simple operation, easy to use, used in industrial and mining enterprises, storage terminals and other places.
Composition and structure:
Weight is generally 0.1 ~ 80 tons, lifting height of 3 to 30 meters. Is composed of motor, drive mechanism and the drum or sprocket, divided into steel wire electric wire rope hoist and electric wire rope chain hoist two. The electric wire rope hoist chain is divided into two kinds of import and domestic; wire rope electric wire rope hoist single speed upgrade, double speed hoist lifting; micro electric wire rope hoist, windlass, multi function.
Reducer, motor, motor, lifting off firearms, cable slide wire, reel, hook device, the coupling, soft cable into the current device, power and braking force in one.
Lifting weight: 0.25t-80t
Lifting height: 3m-30m
Working class: M3, M4
The running speed of 20 (30): m/min
Hoisting speed: 8m/min
The installation and use of:
Electric wire rope hoist is usually installed in a single beam crane, bridge crane, gantry crane, crane. Slightly modified, can also be used for winch. Therefore, it is to improve labor efficiency, better working conditions.
Operating conditions:
Environment temperature: -20 ℃ ~ +40 ℃
Operating system: intermediate JC25%
Heavy: JC40%
When the intermediate system electric wire rope hoist weight decreased 30%, the heavy duty work system of JC40% electric wire rope hoist.
Heavy duty system of JC40% electric wire rope hoist is used in heavy load work, often in ratings or safety coefficient under the condition of higher.
Electric wire rope hoist reducer: using three fixed axis gear rotating mechanism, made of alloy steel, after heat treatment of gear and gear box, the box cover is made from high quality cast iron, assembly is close, good sealing. The reducer has a component, loading and unloading is very convenient.
Control box: can be used to cut off the main circuit in case of emergency, and with the up and down stroke protection cutoff limit device regulator. To ensure the safe operation of the electric wire rope hoist. The life of electrical components, the use of reliable.
Wire rope: using GB1102-74 (6*37+1) X hoisting wire rope, ensure durable.
Conical motor: the lifting motor with large starting torque of the conical rotor brake asynchronous motor, and no additional brake. The motor load sustained rate of 25%, class B or class F insulation adopts motor, motor protection class IP44/IP54.
Button switch: hand operation is light and handy, a rope control and wireless remote control in two ways.
Part of the electric wire rope hoist: motor, drive mechanism, roller and sprocket.
The motor and the reel mutually different positions can be divided into four types.
(1) the motor axis perpendicular to the drum axis of the electric wire rope hoist uses the worm gear, width of large size, heavy weight, low mechanical efficiency, difficult processing has no manufacturers of this type of product.
(2) the motor axis parallel to the drum axis of the electric wire rope hoist, the utility model has the advantages of small size and length of the height. The disadvantage for large width, grouping, manufacturing and assembly of complex. Orbital radius.
(3) motor installed in the drum inside the electric wire rope hoist, the utility model has the advantages of compact structure small size for length. The main drawback for motor cooling condition is poor, packet difference, inspection, installation, motor maintenance inconvenience, power supply device complex.
(4) motor installed in the outside of the electric wire rope hoist reel, the utility model has the advantages of packet is good, high level of generalization, changing the lifting height is easy, convenient installation and maintenance. The disadvantage of large size.
