Skidding System

Skidding techniques have been used for centuries. Enerpac has applied high-pressure hydraulics to create the Enerpac HSK Skidding Systems. The HSK skidding system is comprised of a series of skid-shoes powered by hydraulic push-pull cylinders, travelling over a pre-constructed track. A series of special PTFE coated blocks are placed on the skid-tracks to reduce friction. The skid shoes are connected by hoses to a hydraulic diesel driven power pack.

Enerpac Skidding Systems are available in several versions:

  • HSKB-Series (Skid Shoe Beam) utilizes a tall skid shoe with built-in push/pull cylinders. Skidding direction can be easily switch by flipping a lever on the attached gripper box.
  • HSKJ-Series (Skid Shoe Jack) provide the same functionality as the HSKB with the added benefit of having a built-in cylinder for lifting or leveling the load.
  • HSKLH-Series (Low Height Skid Shoe) designed with low height skid shoes that can be linked together. The push/pull cylinder (sold separately) is connected to the first shoe. We also offer a support beam for using the thin track that is not fully supported.

To calculate the minimum required capacity per shoe, the entire load has to be able to rest safely on 2 of the 4 shoes. To skid a load of 500 tons, the required skidding system is HSK2500.
