The Secret to High-Molecular-weight Polyethylene (UHMWPE) Outrigger Pads in Improving Lifting Efficiency
Time : 02/02/2026

During crane operations, the outriggers are crucial for bearing the weight of the entire machine, and the outrigger pads act as "invisible guardians," protecting the ground and stabilizing the equipment. UHMWPE outrigger pads, with their unique advantages, have become the preferred choice for on-site operations in construction and ports.


The outstanding advantages of UHMWPE outrigger pads are their lightweight yet robustness. Compared to traditional steel plate pads, they have a significantly lower density, reducing weight by more than half. Workers can easily handle them by hand, eliminating the need for additional mechanical assistance and greatly improving operational efficiency. However, lightweight does not equate to poor durability. Their ultra-high molecular weight makes them highly impact-resistant and pressure-resistant. Even when bearing hundreds of tons of weight, they will not crack or deform, firmly supporting the crane's outriggers.

Furthermore, UHMWPE outrigger pads are wear-resistant and corrosion-resistant. Whether repeatedly rubbed against gravel surfaces or exposed to acids, alkalis, or oils, the surface remains intact, and they are not easily damaged even after long-term use in harsh environments. Meanwhile, the UHMWPE outrigger pads offer excellent anti-slip properties. The textured surface increases friction, ensuring a firm hold even on wet or muddy surfaces, preventing equipment slippage and displacement.


Furthermore, UHMWPE outrigger pads are adaptable to various weather conditions, functioning stably in both sub-zero and scorching temperatures. They effectively distribute outrigger pressure, preventing ground subsidence and protecting the road surface and foundation. They also reduce equipment sway, ensuring safe crane operation and making them an indispensable tool for on-site work.
