  • Patent number: 5755540
    Abstract: A vehicle transporter has an elongate vehicular frame with vehicle support members movable between different elevations relative to the frame. Respective telescopically-movable fluid power cylinder assemblies interconnect respective ones of the vehicle support members with the frame to selectively raise and lower the vehicle support members by telescopic movement of the cylinder assemblies. Each cylinder assembly has one or more respective locking members for preventing telescopic movement of the cylinder assembly in a lowering direction, to enable the cylinder assembly to support a respective vehicle support member independently of any fluid in the cylinder assembly. A remote control system is connected to each of the locking members to control its locked and unlocked positions. The locking members are movably mounted on a respective cylinder of each cylinder assembly.
