Hydraulic dock levelers offer push button operation, improved reliability and less maintenance and repair costs than mechanical dock levelers. The conversion kit is an economical alternative to replacing an existing dock leveler. This upgrade is designed to cost considerably less than full replacement of the existing dock leveler and / or installing a conversion kit that is not designed specifically for the Pentalift brand dock leveler.
