Abstract: A lift/tilt-bed trailer. Apparatus is described for either raising from or lowering to the ground a trailer bed in a single step while maintaining a substantially horizontal attitude relative thereto, or for tilting the trailer bed which is normally positioned parallel to the ground when the trailer is in its traveling mode for the purpose of loading or unloading the bed without substantial change in the orientation of the trailer "U"-frame in which the bed is located. Four pivotable tracks attached to the frame and corresponding roller wheels attached to the bed cooperate to achieve the desired motion. Since the trailer need not be detached from whatever device is used to move it about when it is to be loaded or unloaded, increased stability results with consequent reduction in risk to the operator.

Abstract: A method and apparatus for loading of a piece of equipment on a lorry. The apparatus includes an arm pivotally interconnected with the lorry and a first jack interposed the lorry and the arm. A jib is telescopically interconnected with the arm. A movable platform is interconnected with a hook on the jib. A cable passes over a pulley interconnected with the movable platform and is hooked to the chassis at one of its ends and to the piece of equipment at the other of its ends. The method includes the steps of moving the piece of equipment rearwardly along the movable platform, the movement of the piece of equipment therealong acting through the cable and pulley to displace the movable platform rearwardly relative to the lorry until the movable platform and the piece of equipment are displaced to a position wherein they are unbalanced on the lorry. Gravity is then used to permit the lowering, by a tilting action, of the movable platform.

Abstract: In a dump truck, the most efficient way of raising the container body is to apply a lifting force to the end of the body remote from the pivot point. In some applications it is difficult to do so because of height restrictions and it is particularly difficult to do so in a telescoping container body in which the end of the container body which is remote from the pivot point moves in relation to the pivot point. The present invention overcomes this difficulty by mounting the extensible ram in a position remote from its upright position and providing a mechanism for pivoting it to its required upright position prior to its operation as a hoist. In a telescopic container body, the extensible ram is normally stored in freeboard space disposed below the front section of the container body and is raised into an upright position at the front end of the telescoped body in response to movement of the front section from its extended position to its retracted position.

Abstract: The device comprises a derrick with a main telescopic arm and an auxiliary arm. The telescopic arm 9 is pivoted on a sub-frame which in turn is pivoted to the main chassis of the vehicle. At the front the main vehicle chassis 3 is mounted a cam having ramps 20 and 21 on which travels a roller mounted to the free end of the telescopic arm. In order to tip the load on the vehicle, the telescopic arm is first contracted, providing a slight upward swing of the arm when the roller 22 climbs the ramp 20. This appreciably relieves the load requirements of the tilting jack thereby enabling handling of larger loads.
