Wire rope electric hoist structure and characteristics: The machine uses a mechanical and electrical integration design, the replacement of different molds, you can suppress the different specifications of the wire rope, easy to control, safe; inspection, installation, maintenance of motor convenience. The main drawback is the poor preheat of the motor, poor packetization, power supply, manufacturing and assembly complex.
Wire rope electric hoist classification and description of the wire rope electric hoist components are: motor, the idea of the head, reel and sprocket. The different positions of the motor and the drum can be divided into four types. Pressed steel rope pull large, beautiful, fast, crimping a set of wire rope can be completed in just a few minutes, greatly reducing the labor intensity, improve the efficiency.
Motor installed in the reel outside the electric hoist, the advantages of good for the grouping, a high degree of generalization, change the height of the lift easily, the device test convenience.
Electric hoist is widely used, but the correct operation of electric hoist professionals less, it is recommended that you learn more about electric hoist knowledge, and then in all areas to better use a variety of electric hoist.
Electric hoist mainly divided into: electric chain hoist, wire rope electric hoist (explosion-proof gourd), anti-corrosion electric hoist, double reel electric hoist, hoist, mini electric hoist, group hanging electric hoist, multi-function hoist.
Application areas: lifting, pulling, loading and unloading heavy objects, oil tank flip welding, such as various large and medium-sized concrete, steel structure and mechanical equipment installation and movement for construction and installation companies, factories and mines of civil engineering and bridge construction, Electricity, ships, automobile manufacturing, construction, roads, bridges, metallurgy, mining, slope tunnels, shaft protection and other infrastructure construction machinery and equipment.
(1) check the work before use
a. Within the scope of the operator's walk, the line of sight, the passage of heavy objects should be free of obstacles and floating objects.
b. Manual button up and down, left and right direction should be accurate action, the motor and reducer should be no abnormal sound.
c. Brakes should be sensitive and reliable.
d. electric hoist running track should be no foreign body.
e. The upper and lower limiters should be accurate and sensitive.
f. hook hook nut should be fastened firmly.
g. The hook should be flexible in horizontal and vertical directions.
h. hook pulley should be flexible.
i. Wire rope should be no obvious cracks, arranged in the reel on the neat, no pulley groove, torsion, buckle and other signs, good lubrication.
j. There is no abnormal phenomenon.
k. Electric hoist working environment temperature is -25 ~ +40 ℃
l. Electric hoist does not apply to corrosive gases or relative humidity greater than 85% of the place, can not replace the explosion-proof gourd, not lifting metal or toxic, flammable and explosive materials.
(2) electric hoist shall not be lifted off the weight, prohibit overload use.
(3) in the use of the process, the operator should always check whether the wire rope buckle, knot, pocket, wear and other phenomena, if the emergence should be promptly excluded, and often check the guide rope and limit switch is safe and reliable.
(4) in the daily work can not artificially use the limiter to stop the lifting of heavy objects or stop the operation of equipment.
(5) After the work is completed, turn off the main power switch, cut off the main power supply.
(6) should be set up a special maintenance staff on the main performance of electric hoist and safety status check once a day, found that the failure to rule out.
