Jacking Load Shoes are load-compensating skid shoes designed to work with our Heavy Track skidding systems to provide increased load-handling capability.

Jacking Load Shoes both increase the maximum load capacity of our skidding systems, and work to equalize the load distribution across all points. The load can also be raised and lowered during skidding operations.

No, the weight of your load doesn't‎ have an effect on the speed of operations. Skidding and jacking speed is based purely on the pump flow rate and the size of the cylinders.

The equipment performed perfectly and made us look impeccable to our client. Hydra-Slide equipment was the only way we wanted to tackle this project, and we honestly never even considered using anything else."

Myshak Crane & Rigging utilized its entire fleet of Hydra-Slide hydraulic skidding equipment, including six JLS250 Jacking Load Shoes, to change out a horizontal converter at a fertilizer production plant in Alberta, Canada. The old and new converters weighed 514 tonnes and 520 tonnes respectively. The JLS250 jacking load shoes were hydraulically connected in a three-point suspension to lift and slide the converters on the HT300 track. Both Hydra-Slide and Myshak agreed that the project was a prime example of a rigging crew and all parties involved working together to pull in the same direction. Teamwork and collaboration on this high-profile project made a successful outcome possible.
