Polyethylene crane leg pad easy to use ?
The polyethylene leg pad includes a plate-shaped pad body, and the leg pad also includes a portable rope made of nylon material. The end of the portable rope is embedded in the pad body. Due to the high compressive and shear resistance of ultra high molecular weight polyethylene (UHMWPE), its strength and stiffness are respectively higher than those of conventional base plate materials. Therefore, the base plate body of this type of leg base plate has higher strength and stiffness, which can reduce the deformation of the base plate body under stress and provide more stable support for construction machinery. The leg pads made of ultra high molecular weight polyethylene also have a smaller thickness and weight, making them easy to carry and arrange.Polyethylene crane leg pads are used to pad under the legs of construction machinery
1. Lifting operations can only be carried out when all outriggers are fully supported on a flat and firm ground. If the ground does not meet the requirements of the relevant regulations, sufficient land preparation work should be carried out in advance, and the operation can only be performed after confirming that it is safe and qualified.
2. In case of special (soft or inclined) ground, the outrigger plate or steel plate of the crane that is suitable for the ground must be used under the outrigger plate to make it flat, and ensure that it is firm and must not sink during the lifting operation.
3. When using the crane outrigger pad, the crane outrigger pad must have a solid structure that can fully withstand the pressure of the outrigger. If a steel plate is placed under the outrigger plate, a thick steel plate with small deformation should be used.
4. When leveling the outriggers, keep all tires off the ground to avoid unstable support or damage to tires and bridge bolts during lifting operations.
