Requirements for the steel wire rope of the hydraulic lifts

Hydraulic lifts are widely used in factories, warehouses, industrial plants, institutions—anywhere that products or supplies need to move from one level to another. Guide rail lift provides fast, efficient,convenient and safe access to mezzanines, balconies, basements, and any levels in multi-storied building. The freight elevator can be installed indoor and outdoor,


Hydraulic goods elevator not only have all safety device of the traditional elevator, but also have the special system:

1,Spillover valve, it can prevent high pressure when the machine moves up.

2,Manual emergency valve, it can go down to the nearest floor and open the door when meet an emergency.

3,Manual pump, it can go down to the nearest floor and open the door when meet an emergency.

4,Pipe fracture valve, when the hydraulic system pipe fracture, it can cut down the channel of the oil to stop the falling.


Even though it is widely used in modern construction, but its huge size, the weight is very heavy, so its safety performance requirements are very high in the construction. For critical rope which more stringent requirements. General requirements for safety rope from four specific areas.


1, Replacing the wire rope, wire rope drawn from the reel or roll rope should be to prevent its fight ring, kink, bend or stick on debris. Truncation bit off both sides of the rope should be in with a fine steel wire to knot securely to prevent after cutting loose strands.


2. Do not overload lifting, should be installed overload limiter or torque limiter, and try to avoid using the sudden shock and vibration. It should also be installed from the ceiling positioner to prevent excessive volume to pull off the rope.


3, When the rope friction with certain parts of the machine, should be added to the contact site protection measures; when tied rope angular contact with a suspended load, stow or copper, etc. should be added at the edges and corners to prevent the wire was cut. When lifting weights, rope hanging oblique allowed to prevent chaos rope failure.


4. The new rope should be replaced with the same type of original installation of the rope, the same size, the use of a different type, you should ensure that the new rope is not less than the old rope performance, and can match with the drum and pulley groove; rope twist to be consistent with the direction of the spiral groove rope reel, single winding rope guide should be set up to prevent chaos rope.


Safety device is essential, since the safety of people plays a vital role. Hydraulic lift in the rope more must guarantee the achievement of the requirements.
