Break-in pads are widely used in mining lifting equipment. So, what role do block shaped objects of different colors play in lifting equipment? The following text discusses the role and importance of running in gaskets from imported gasket manufacturers.

a) Guarantee coefficient

The break-in lifting equipment uses the power of break-in and steel ropes to lift heavy objects and people. The coefficient varies depending on the lining material. It is an important component of the running-in lifting equipment. The weight of all steel ropes, container self weight, loading weight, balance tail rope weight, and various loads and impact loads during operation must have sufficient compressive strength. In order to prevent sliding during the lifting process, there must be sufficient coefficient with the steel rope.

b) Protective steel rope

It has a good protective effect on steel ropes. Macroscopically, imported liner manufacturers believe that the softer the material, the more favorable it is for the steel rope, while ensuring the support strength.

The coefficient is the most important factor in the interaction and sliding with the steel rope. After selecting the wrong coefficient for running in, the interaction force decreases, leading to relative sliding and rapid loss of the steel rope. Imported gasket manufacturers believe that loss is a multiple factor and analyze the impact of coefficient on coefficient to better prevent and reduce loss, thereby extending service life.

The coefficient is divided into dry rope coefficient, wet rope coefficient, and lubricant coefficient. The coefficient on the main wheel is related to the rope pressure of the steel rope, and imported liner manufacturers believe that various coefficients also vary under different rope pressures. Our company's long-term experiments and experience have shown that the coefficient value of WK868 high-performance friction lining can reach 0.41 in dry environments, and can reach 0.6 in wet and grease conditions. This coefficient has a large fluctuation space, but it meets the requirement of 0.25 for break-in lifting equipment. It can always maintain a coefficient above 0.25 for break-in lifting equipment. Therefore, imported lining manufacturers believe that accidents such as sliding ropes are not easy to occur.

Improper use of coefficients can cause container slippage accidents, so it is necessary to use suitable coefficient running pads according to working conditions.

The characteristics shared by imported liner manufacturers are as follows:

The coefficient under various working conditions is greater than 0.25, fully meeting the requirements for the use of multi rope running-in lifting equipment.

2. The liner is a material with high mechanical strength that will not damage the steel rope, making it easy to process rope grooves on site.

3. The test results show that the heat resistance, melt resistance, and loss are better than those of the K25 import, and the equal power loss is the same as that of the K25 import.

4. It has good compatibility with running in grease. Both imported and domestic running in grease are suitable.

5. The steering performance of the crown wheel is stable, reliable, and reasonably priced, which can bring significant economic benefits to users.
