The model HCK2 Pentalift Universal Hydraulic Conversion Kit takes a structurally sound dock leveler and converts it to reliable, safe fully hydraulic operation. It is designed to fit into a wide variety of dock levelers, including competitive brands. The conversion kit is an economical alternative to replacing an existing dock leveler. This upgrade costs considerably less than the cost of fully replacing the existing dock leveler with a new hydraulic dock leveler and dramatically reduces down time and repair costs on existing dock levelers.
