Pile Driver Cushions

What is a Pile Driver Cushion?

A pile driver cushion is a component used in construction for pile driving operations. It's a cushioning device positioned between the pile and the pile-driving hammer to absorb shock and prevent damage to both the pile and the hammer during the driving process. 

The cushion typically consists of materials like wood, metal, or plastic designed to absorb and distribute the impact force generated by the hammer. Its primary purpose is to protect the structural integrity of the pile being driven and to ensure that the force is transmitted efficiently without causing excessive stress or deformation to either the pile or the hammer. 

Also referred to as Hammer Cushions, Pile Cushions, Cushion Blocks, Pile Hammer Cushion Pads and Buffer Pads.

Benefits of Plastic Pile Driver Cushions

  • Efficient – when the plastic is formulated from the right resins, together with the appropriate additives, the resultant properties provide good load transmission for efficient and productive driving, together with good shock absorption. 
  • Low Noise – particularly compared to aluminum cushions, plastics are quieter, and therefore can be used continuously in built up areas. 
  • Heat Resistant – Nylatron MC904P has been formulated to resist heat heating but the temperatures generated by high frequency hammer “blows”. 
  • Light Weight – This aids handling and transport 
  • Durable & resilient – Nylatron MC904P cushions are durable and resistant to wear, making them suitable for repeated use. 

Dotmar has qualified engineers that can provide direct support with plastic Pile Driver Cushion sizing and configuration, which is based off decades of experience in the manufacturing of materials and designs.

MATERIAL SELECTION CONSIDERATIONS

Material selection is a critical consideration when choosing a material for Pile Driver Cushions, as it directly impacts the performance, durability, and safety. Here are some key material selection considerations for pile driver cushions:
Force Transmission
Having the right combination of strength and toughness is required to achieve efficient and productive piling, without damaging the pile.
Noise
Especially significant in built up areas, minimizing the noise generated by constant and frequent blows is imperative to comply with noise restrictions.
Temperature
Constant and frequent hammering for efficient and productive piling will generate heat. The right material selection will minimize the heat generated (wasted energy) and also resist heat aging degradation.
Fire Retardant
Heat generation can result in some material spontaneously igniting, which will be damaging to equipment and be a safety hazard.
Regulatory Requirements
Does the application have regulatory requirements such as food contact, drinking water, anti-static or flame retardant. The food industry may also require materials to be metal detectable, x-ray detectable and/or visually detectable by being coloured blue.
