Electro-hydraulic pit jack for lifting up commercial vehicles, agricultural machinery and other special vehicles over pits. The carriage construction is fitted to the width of the pit (any specification should be defined at ordering on a separate data sheet) from 790 to 1100 mm, to be adjusted accurately and fixed with bolts and nuts. Four so-called bogie wheels allow the carriage to be rolled manually. The cross-axle carriage containing a hydraulic unit is also rolling on wheels thus it can be easily pulled to the proper position.
