What is the function of crane stabiliser pads?

Crane stabiliser pads (usually made of high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMW-PE)) are a very important industrial component. Its function can be summarized as: utilizing the excellent properties of polyethylene materials to provide support, isolation, protection, and regulation between equipment, structures, or materials, while avoiding damage and corrosion.
The following is a detailed breakdown of its specific function:
1、 Core function: support and load distribution
Support and leveling of heavy equipment
Application scenarios: Used to support large mechanical equipment, heavy-duty shelves, steel structures, bridge components, prefabricated concrete components, etc.
Function: Effectively distribute concentrated loads to a larger foundation area, preventing equipment from sinking or tilting due to excessive pressure. Meanwhile, it can be used for precise leveling of equipment to ensure its stable operation.
Temporary support and maintenance
Application scenario: Used as an auxiliary support pad for jacks during equipment maintenance, tire replacement, or lifting operations.
Function: To provide a stable, sturdy, and non slip support surface, withstand tremendous pressure, greatly improve work safety, and avoid the risk of breakage and slippage that may occur with irregular stones or wooden blocks.
2、 Protective function: prevent wear and damage
Isolation and protection of surfaces
Application scenario: When hoisting, transporting, and storing sensitive materials such as precision components, stainless steel plates, glass, marble panels, etc., it is placed between the goods and ropes, brackets, or the ground.
Function: Polyethylene is softer than metal, and its smooth surface will not scratch or wear the precision surface. It acts as a buffer barrier, protecting the appearance and quality of the product, and avoiding losses caused by scratches.
Reduce noise and vibration
Application scenario: Placed under the machine base.
Function: Polyethylene has certain elasticity and energy absorption properties, which can help absorb the vibration and noise generated by equipment operation and improve the working environment.
