Abstract
A wheeled jack, comprising a chassis shaped like an articulated parallelogram in which a lower horizontal side is provided, at its two front sides, with respective pairs of tilting wheels and the front end of the upper horizontal side is provided with an articulation for the centerline of a transverse arm for supporting clamps for gripping a pair of wheels of a vehicle, each one of the pairs of front tilting wheels being fitted at the ends of a rocker lever and able to swivel about vertical axes, the articulation of the transverse clamp-supporting arm being provided with an assembly for locking at different angles.
Claims7
A wheeled jack, comprising:
- a chassis shaped as an articulated parallelogram having a lower horizontal side and an upper horizontal side;
- rocker levers provided connected at a front end of said lower horizontal side on both sides thereof;
- two pairs of front and rear tilting wheels, provided each supported by a respective one of said rocker levers so as to be able to swivel about vertical axes thereof;
- supporting clamps for gripping and supporting a pair of wheels of a vehicle to be lifted;
- a transverse arm that supports said supporting clamps;
- articulation means, provided at a front end of said upper horizontal side, for connecting thereto a center region of said transverse arm;
- said articulation means comprising a locking assembly for locking at different angles said transverse arm upon rotation thereof about a vertical axis passing through said center region thereof.
A wheeled jack, comprising:
- a chassis;
- rocker levers provided connected to said chassis at opposit sides thereof;
- two pairs of front and rear tilting and swiveling supporting wheels each supported by a respective one of said rocker levers so as to be able to swivel about vertical axes thereof for ground supporting and maneuvering;
- abutments protruding laterally from said chassis in an intermediate part thereof;
- articulation means;
- a transverse arm articulated centrally by way of said articulation means to a front part of said chassis;
- and clamps supported at respective ends of said transverse arm so as to be movable from an open position in which the clamps are suitable to allow insertion of the front part of the chassis between internal sides of a pair of wheels of a vehicle to be lifted with the abutments abutting against first tread portions of the vehicle wheels, and a closed position in which the clamps secure the vehicle wheels by closing on respective tread clamp portions thereof that are located in regions that are opposite, with respect to hubs of the vehicle wheels, to said first tread portions;
- and wherein the articulation means comprising a locking assembly for locking said transverse arm at different steering angles.
