The EK125HH from CZM Foundation Equipment is a hydraulic pile drive machine mounted on a CAT323 Next Gen base and equipped with a free fall hydraulic impact hammer. This free fall feature has multiple advantages:

  • Half the life cycle is maintenance-free because it’s operated by gravity
  • Less fuel consumption due to lower installed power
  • No need for impact reaction absorption by the hydraulic circuit when ram hits the pile mean a much higher durability and the ability to work with any kind of bearing capacity and/or refusal specification
  • Improved rate ratio between piston weight and total hammer weight with higher efficiency compared to similar sized machines

Another important feature of the CZM hammer is the use of two external hydraulic cylinders which lift the ram up to the controlled height, making it quick and easy to visually inspect and access for maintenance.

EK125HH is a compact machine with quick setup for operation and transport mode. In addition in it a single-load piece of equipment. The 360º of swing and its parallelogram allows for agility in the pile location and the ability to work with very tight access.

The computer in the cabin controls a precise drop height and driving frequency on the already renowned high energy transfer efficiency of this kind of hammer.
