Low headroom electric wire rope hoist

Low headroom electric wire rope hoist

Wire rope electric hoist
Composition:
The lifting capacity is generally 0.1~80 tons, and the lifting height is 3~30 meters. It is composed of motor, transmission mechanism and drum or sprocket. It is divided into wire rope electric hoist and ring chain electric hoist. Among them, electric chain hoists are divided into imported and domestic ones; Wire rope electric hoist is divided into single speed lifting and double speed lifting
promote; Miniature electric hoist, hoist, multi-function hoist.
Reducer, lifting motor, running motor, flame breaker, cable sliding wire, drum device, hook device, coupling, flexible cable current inductor, etc. integrate power and braking force.
Lifting capacity: 0.25t-80t
Lifting height: 3m-30m
Working level: m3, M4
Running speed: 20 (30) m/min
Lifting speed: 8m/min
Installation and use:
Electric hoist is generally installed on single beam crane, bridge crane, gantry crane and suspension crane. With a little modification, it can also be used as a winch. Therefore, it is a necessary machine to improve labor efficiency and working conditions.
Operating conditions:
Ambient temperature: -20 ℃ ~+40 ℃
Working system: intermediate jc25%
Weight grade: jc40%

When the lifting capacity of the electric hoist in the intermediate working system is reduced by 30%, it is the electric hoist in the heavy working system jc40%.
Heavy duty working system jc40% of electric hoists are used when the work is heavy and the load is often at the rated value or requires a high safety factor.
Electric hoist structure reducer: it adopts a three-stage fixed shaft helical gear rotating mechanism. The gear and gear shaft are made of heat-treated alloy steel. The box body and cover are made of high-quality cast iron, which are tightly assembled and well sealed. The reducer is a part of itself, which is very convenient for loading and unloading.
Main features:
The advantage of wire rope electric hoist is that its length and size are small, and the motor is installed in the drum.
The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the drum axis adopts worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, difficult processing, etc.
Structure and features: the machine adopts the electromechanical integration design. By changing different molds, different specifications of steel wire ropes can be pressed, which is simple and safe to control. Its main disadvantages are poor heat dissipation premise of the motor, poor grouping, convenient inspection, installation and maintenance of the motor, and complex power supply device. The electric hoist with the electric motor axis parallel to the drum axis has the advantage of small height and length. Its disadvantages are large width, poor grouping, and complex manufacturing and assembly.
Classification and description of wire rope electric hoist the components of wire rope electric hoist include: motor, transmission mechanism, drum and sprocket. It can be roughly divided into four types based on the different positions of motor and drum. The pressed steel wire rope has large tension, beautiful appearance and fast speed. It only takes a few minutes to crimp a set of steel wire rope, which greatly reduces the labor intensity and improves the work efficiency.
The electric hoist with the motor installed outside the drum has the advantages of good grouping, high generalization, easy to change the lifting height, and convenient device inspection.
Application fields:
Application fields: lifting, hauling, loading and unloading heavy objects, upside down welding of oil tanks, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment. It is suitable for construction and installation companies, civil construction projects of factories and mines, and mechanical equipment of infrastructure construction projects such as bridge construction, electric power, shipbuilding, automobile manufacturing, construction, roads, bridges, metallurgy, mines, slope tunnels, shaft governance and protection.
Use and maintenance:
1. For the electric hoist newly installed or installed after disassembly and inspection, the empty vehicle test run shall be carried out for several times at first. However, before the installation is completed, do not power on for trial run.
2. Before normal use, a static load test should be carried out at 125% of the rated load and about 100 mm above the ground for 10 minutes to check whether it is normal.
3. The dynamic load test is to conduct repeated lifting and moving tests to the left and right with the rated load weight. After the test, check whether the mechanical transmission part, electrical part and connecting part are normal and reliable.
