(1) Corresponding professional steel wire ropes should be selected for elevator and aviation steel wire ropes

(2) Corresponding special steel wire ropes should be selected for steel wire ropes for high lift construction tower cranes

(3) Wire ropes for cranes, piling machines, drilling rigs, electric shovels, excavators and other machinery with low lifts are required to have good wear resistance, fatigue resistance and impact resistance, and 6*29Fi or 6*36SW can be selected. Structural Wire Rope

(4) For equipment operating in high temperature environment or requiring large breaking load, metal core wire rope can be selected

(5) Steel wire ropes for shipping, ships, fisheries, bundling wood, etc. are required to be corrosion-resistant and soft. Type A galvanized steel wire ropes of 6*19, 6*24, 6*37 and other structures can be used

In addition, the tensile strength of the steel wire rope should be selected according to the load used and the specified safety factor, and the appropriate strength level should be selected, and it is not suitable to blindly pursue high strength. In a word, the appropriate wire rope should be selected according to the characteristics of the equipment and the working occasion, and the purpose of safety, prolonging the service life and improving economic benefits should be confirmed.

2. Installation of wire rope

(1) Unwinding

When unwinding, the rope reel should be placed on a special bracket, or a steel pipe can be inserted into the rope reel hole, and ropes are placed at both ends to hoist, and the rope reel should be slowly rotated (see the middle picture below)

(2) Arrangement of wire ropes on the drum

The winding direction of the wire rope on the reel must be based on the twist direction of the wire rope. The right-twist rope is arranged from left to right, and the left-twist rope is arranged from right to left. (see image below right)

(3) Cut

When cutting the steel wire rope, the two sides of the cutting place should be 10-20mm apart and fastened with iron wire, and the binding length should be 1-4 times the diameter of the rope, and then cut off with a cutting tool.

 

3, Maintenance and inspection of wire rope

(1) run

The speed of the wire rope should be stable during operation, and it should not exceed the load to avoid impact load

(2) Maintenance

The wire rope has been coated with enough grease during manufacture, but after running, the grease will gradually decrease, and the surface of the wire rope will occupy dust, debris and other contaminants, which will cause the wire rope and sheave wear and the wire rope to rust. , should be cleaned and refueled regularly. The simple method is to use a wire brush and other corresponding tools to wipe off the dust and other dirt on the surface of the wire rope, apply the surface grease of the heated and melted wire rope evenly on the surface of the wire rope, or spray No. 30 or No. 40 engine oil on the surface of the wire rope. , but do not spray too much and pollute the environment.

(3) Checked records

The use of wire ropes must be regularly checked and recorded. In addition to the above cleaning and refueling, the content of regular inspections should also check the degree of wear, broken wire, corrosion, fishing hooks, rings, lubricating grooves, etc. Condition of wear of consumable parts. If abnormal conditions are found, it must be adjusted or replaced in time.
