A lifting apparatus which is readily portable between locations and whose design allows for readily replacement and/or repair of component parts thereof to enhance both serviceability and maintenance of the lifting apparatus is disclosed. The lifting apparatus includes a support table, a base frame disposed beneath the support table, a linkage assembly for maintaining the table and the base frame in generally parallel relation relative to each other as the table moves between raised and lowered positions, and a pneumatically operated actuator for moving the table between the raised and lowered positions. The base frame of the lifting apparatus defines at least one opening for allowing tines of a moving device to be inserted therethrough, thus, allowing the lifting apparatus of the present invention to be readily transported between locations. Fasteners used to releasably secure the pneumatically operated actuator to the base frame are elevated above the surface on which the lifting apparatus is positioned thereby enhancing serviceability of the pneumatically operated actuator. Additionally, the base frame includes gib structure arranged in operable combination with the linkage assembly and which includes releasable structure for enhancing service access to rollers forming part of the linkage assembly.
