Factors Affecting the Service Life of Ship Unloader Wire Rope

The application of ship unloader in the port terminal is very common. Due to long-term use, the ship unloader wire rope bears the static load of the heavy object itself, but also constantly bears the dynamic load. In addition, the service life of the wire rope will be greatly affected by the repeated friction force between the ship unloader and the pulley.

Factors Affecting the Service Life of Ship Unloader Wire Rope

The application of ship unloaders in port terminals is very common, due to long-term use, ship unloaderswire ropeWhile bearing the static load of the heavy object itself, it is also constantly bearing the dynamic load. Coupled with the repeated friction with the pulley, the service life of the wire rope will be greatly affected. When the number of use exceeds a certain limit, the wire rope will appear fatigue damage, which will affect the working safety of the ship unloader. At the same time, the regular replacement of the wire rope also increases the economic cost. To study the factors affecting the service life of wire rope and determine its impact on economy can effectively reduce costs. Specific factors, Luoyang Baikte Technology Development Co., Ltd. to tell you!
1. Frequency of use
The use frequency of wire rope is generally measured by daily working time. In the total time range, the more the average daily working time, the greater the probability of fatigue damage of the wire rope, and the more serious the impact on its service life. Therefore, under the same working conditions, Use frequency can be used as the main criterion for judging the service life of wire rope.
2. Load case
The wire rope will be subjected to a variety of loads during use. The static load of heavy objects and the impact dynamic load have a greater impact on the service life of the wire rope. When the wire rope is subjected to repeated loads for a long time, due to the continuous stretching of the rope, The micro-strain gradually increases, and damage will occur after exceeding the elastic pole.
3. Lubrication condition
Wire rope will often wear with bearings and gears during work. Wire rope will rub against other parts. Specifically, the following reasons may cause wire rope wear: 1) Wear of contact parts caused by insufficient lubrication; 2) Wear caused by mixing dust and abrasives; 3) Chemical corrosion caused by wire rope exposed to humid air; 4) Accumulation of damage caused by impact and overload; 5) Continuous friction between the wire rope and the drum. When the lubrication degree of the contact surface is insufficient, the wire rope is prone to fracture; 6) The long-term friction of the metal will make the surface of the wire rope more fragile. The surface of the steel wire after embrittlement is more likely to crack and destroy.
