6x19+FC Electric Hoist Steel Wire Rope Full Size Available Galvanized / unGalvanized
Wire rope electric hoist use 1. before lifting, should be empty load test hanging, check the mechanical operation is normal, wire rope is intact, and the wire rope is normal, no trough, hopping, jumping stock phenomenon, prohibit wire rope disks. If abnormal, the cause must be identified, and be activated after repair. 2. operators are strictly prohibited from standing under the hook. Operators should take the initiative to avoid and prevent unrelated personnel from entering the work area. 3. operators must concentrate their minds and work closely with their partners to ensure that they are safe under the condition of safety. 4. for electric hoist regular inspection, maintenance, maintenance, so that the equipment at any time in good condition, especially to see the wear of wire rope, wire rope once broken wire must change wire rope, strictly prohibit disease operation. 5. installation, debugging and maintenance, it is necessary to strictly check the flexibility of the limit device. When the hook rises to the top of the limit position, the distance between the hook shell and the drum shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the lower limit, the wire rope safety circle on the drum should be ensured. The effective safety circle must be 2 times above. 6. the scrapping standard of wire rope: the inspection and abandonment standard of wire ropes shall be carried out according to the CB/T5972-1986 practical code for inspection and discarding of wire ropes for crane. 7. the use of electric hoist must maintain sufficient lubricating oil, especially the wire rope must be regularly coated with lubricating oil, and keep the lubricating oil clean, should not contain impurities and dirt. When wire rope is oiled, hard brush or wood chips should be used. It is strictly prohibited to directly use hands to oil the wire rope that is working. When the electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent permanent deformation of parts. Especially for wire rope damage is the largest, the wire rope will be stretched, and finally no toughness, resulting in fatigue broken wire, wire rope life expectancy is shorter.
In addition to the cable appliance is the electric hoist, the mechanical function of the wire rope in the components of the electric hoist is most important. After the wire rope electric hoist explanation, we will explain the electric hoist inside the wire rope, the past electric hoist wire rope: the use of GB1102-74 (6*37+1) X type lifting steel rope. Because he is more flexible than 6*19. However, due to the past domestic wire rope industry, there are only several kinds of wire rope, and it is limited to point contact. Now the electric hoist rope has been improving. The structure of electric hoist wire rope is no longer 6*37,6*19. Instead, it gradually improved to line contact steel wire rope, multi-storey non rotating wire rope, 6*25Fi, 6*29Fi, 18*7,35W*7. Because these structures will last longer and the wire ropes more durable. Because replacing wire rope of electric hoist is also a very complicated matter. The electric hoist of domestic crane is usually 0.5 tons -20 tons. The following is the diameter of the wire rope of the electric hoist.
