The invention is for a trolley comprising a carriage and a load-carrying member mounted on said carriage so that relative movement can take place between the carriage and the load-carrying member in the direction of travel of the trolley, said relative movement being effected by a manually operable hydraulic ram. An inclined plane is provided on the load-carrying member and a roller-follower on the carriage, or vice versa. This inclined plane and roller-follower cooperate when said relative move...

Four metal support pipes with casters mounted on the lower ends thereof are arranged at the four corners of a quadrilateral. Pipe cover portions provided at four corners of a plurality of synthetic resin rack boards are threaded over the corresponding support pipes. Synthetic resin spacer pipes are threaded over the support pipes between the pipe cover portions of vertically-adjacent rack boards. Tubular cushion materials which can freely expand and contract are threaded over the support pipes b...

A trolley assembly for use in an automobile lift rack employs individual trolley wheel mounts wherein the wheel is supported by a plurality of elastomeric mounts arranged in vertically displaced, mutual relationship to prevent bending of the mounts when the trolley assembly is loaded.

A trolley suspended on a rail comprising spaced side plates having rollers facing each other on the upper part and coaxial bushings on the lower part, a hanger plate suspended midway between the side plates by a stay rod which passes through said bushings, wherein the stay rod is coupled with a bushing on one of the side plates by a head pin passing through borings provided on said bushing and on one end of the stay rod, and the head of said pin is held down by a spring retainer which is in rele...

The invention concerns a foldable trolley for supporting apparatus such as computers, photocopiers or other office of medical equipment while being serviced. A foldable trolley has a base having two sides each having at a top thereof a support member, connecting members connecting the sides so that they can be moved towards and away from one another, wheel members on which the trolley base is mounted, and a detachable trolley top adapted in a horizontal working position to bridge and be supporte...

A trolley has a pair of front and a pair of rear wheels disposed symmetrically on a chassis relative to a longitudinal axis thereof for ground engaging rotation in a common plane. The chassis incorporates a guide wheel located intermediate the front and rear wheels for ground engaging rotation about a horizontal lateral axis disposed at right angles to the longitudinal axis; a mounting for the guide wheel comprising an arm having a first end, a seocnd end and a section intermediate these ends, t...

A trolley for loading heavy and bulky loads such as a dead animal is of the two wheel type with an upper portion of the frame extending upwardly from the wheels and a forward portion of the frame projecting downwardly toward the ground and forwardly to engage the load. A separate frame portion carries a hand winch and a pulley so that a cable passes over the pulley and can extend downwardly over a covering sheet on the upper portion of the frame. The separate frame carrying the winch can be move...

The trolley has a collapsible structure composed of rigid or semi-rigid, typically cardboard panels. The panels can be folded relative to one another between a collapsed state in which the majority of them lie in compact, coplanar relationship and an erected state in which they define an open-topped box. A wheeled axle is connected to the structure to permit the box to wheeled over the ground. Handles are provided for carrying the structure when collapsed and for steering the trolley when erecte...

A trolley has rear support wheels (20) each having a toggle (52) which, when in a cocked position, hold the wheels in an operative position in which they are able to support the trolley. When the trolley ceases to bear down on the rear wheels, for example when an attempt is made to lift the trolley over a barrier (26) along the periphery of a defined area from which the trolley is not supposed to be removed, the toggle is triggered to move to an un-cocked position. When the toggle is in the un-c...

A sack trolley (1) presents a support frame (2) accommodating lower carrying wheels (3) and an upper handle (4) which is articulated to the lower ends of its side spars (5) by way of hinges (6) on the upper ends of the side legs (7) of the support frame (2) to pivot about a transverse axis (A) parallel to the axis (R) of the carrying wheels, and can be fixed at least in a folded transport position and in an extended use position relative to the support frame (2). To adapt the sack trolley (1) re...
