HDPE Outrigger Pads Description
Made in HDPE, an engineering material that offers a superior combination of impact strength, wear and chemical resistance.
Each pad is equipped with a durable wire handle to allow for easy storage and mobility. HDPE Outrigger Pads are an alternative to wood pads due to their superior characteristics and performance which allows them to last longer.




Property of HDPE outrigger pad
The characteristics of HDPE outrigger pads
1. High strength and high toughness: HDPE material has excellent strength and toughness, capable of withstanding the tremendous pressure exerted by the outriggers of construction machinery without cracking. It can maintain structural integrity under heavy load and provide stable support for construction machinery. For example, in the operation of large cranes, equipment weighing several tons can be supported.
2. Chemical resistance: This pad has excellent resistance to various chemical substances. Common acid and alkali solutions, oil stains, etc. are all difficult to erode it. This feature enables the pad to be used in various harsh chemical environments, thus extending its service life.
3. Uv resistance and weather resistance: When used outdoors for a long time, HDPE outrigger pads can resist UV radiation and will not age rapidly due to direct sunlight. Meanwhile, it can also adapt to different climatic conditions, such as high temperature, low temperature, humidity, etc., ensuring stable performance in various environments.
4. Light weight: Compared with traditional metal or concrete pads, the weight of HDPE leg pads is significantly reduced. This makes transportation and installation easier, reduces labor intensity, and improves work efficiency, especially suitable for work scenarios where equipment needs to be moved frequently.
The principle of ensuring safety with HDPE outrigger pads
1. Distribute pressure: The contact area between the outriggers of construction machinery and the ground is relatively small, which will generate a relatively large pressure. HDPE outrigger pads increase the contact area between the outriggers and the ground, evenly distributing the weight of the equipment over a larger area, reducing the pressure per unit area, and thereby minimizing the risk of ground collapse or damage due to excessive local pressure.
2. Increase friction: The surface of the pad is usually designed with a special texture. This design can effectively increase the friction between the pad and the ground, prevent the construction machinery from sliding or shifting during operation, and ensure the stability of the equipment. For example, on some slopes or uneven ground, increased friction can make the equipment more stable.
3. Buffering and shock absorption: During the operation of construction machinery, vibration and impact force will be generated. HDPE outrigger pads have a certain degree of elasticity, which can absorb and buffer these energies, reduce the impact force on the equipment and the ground, protect the structure and components of the equipment, and also lower the safety hazards caused by vibration.
