Abstract
A loading ramp for loading vehicles onto the bed of a lorry comprising a framework of girders, decking on the girders and legs of variable length at one end of the framework, on which legs the framework can be supported at an inclination to the ground to allow vehicles to be driven or winched up or down the inclined decking. Preferably the loading ramp is mounted on wheels so that it can readily be towed, the wheels being provided on an undercarriage formed as a rigid sub-framework which is slidably movable to position the undercarriage adjacent the raised end of the framework.
Claims23
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of girders,
- decking on the girders, and
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopic members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened, and
- aligned apertures in the telescopic members, whereby, by insertion of a pin, the length of the leg can be set to a desired height,
- said aligned apertures in the first of the telescopic members being provided as longitudinally extending slots therein, the first of the members being externally screw threaded and a nut being provided on said screw thread such that a pin passed through the slot and through one of the apertures in the second of the members bears against the underside of the nut and rotation of the nut on the first of the members lengthens or shortens the leg.
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of griders,
- decking on the girders, and
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopic members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened, and wherein said
- legs include internal gearing incorporating a worm and coupled by a cross shaft rotatable manually by means of a crank handle whereby the second telescopic members can be moved together each with respect to its first telescopic member to lengthen or shorten the leg as desired.
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of girders,
- decking on the girders, and
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopic members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened, and
- wherein each said foot is pivotally mounted with respect to the second telescopic member associated therewith and securing means are provided for holding the said foot in a position in which it is pivoted away from the position it occupies when it bears on the ground.
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of girders,
- decking on the girders,
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopic members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened,
- wheels on which the ramp is mounted, and
- coupling means, whereby the ramp can be trailed behind a motor driven vehicle.
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of girders,
- decking on the girders,
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopic members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened,
- the legs including internal gearing incorporating a worm and coupled by a cross shaft rotatable manually by means of a crank handle whereby the second telescopic members can be moved together each with respect to its first telescopic member to lengthen or shorten the leg as desired,
- wheels on which the ramp is mounted, and
- coupling means whereby the ramp can be trailed behind a motor driven vehicle.
A loading ramp for positioning adjacent the bed of a lorry for loading vehicles thereonto and comprising
- a framework of girders,
- decking on the girders,
- legs of variable length inclined at an angle of less than 90.degree. with respect to the framework and rigidly joined to the framework at or adjacent one end thereof, which legs comprise two telescopic members, a first of the telescopicc members being rigidly secured at its upper end to said one end of the framework and a second of the telescopic members being provided at its lower end with at least one foot to bear on the ground,
- on which legs the framework can be supported at an inclination to the ground with the other end of the framework in contact with the ground, so that vehicles can be winched up or down said decking, and said inclination being variable in accordance with the extent to which said legs are lengthened,
- the legs including internal gearing incorporating a worm and coupled by a cross shaft rotatable manually by means of a crank handle whereby the said telescopic members can be moved together each with respect to its first telescopic member to lengthen or shorten the leg as desired,
- wheels on which the ramp is mounted,
- coupling means whereby the ramp can be trailed behind a motor driven vehicle, and
- a rigid sub-framework mounting the wheels and engaged with and longitudinally moveable with respect to the framework of girders, which rigid sub-framework is so formed and so engaged with the framework that when trailed behind a towing vehicle the decking is at an inclination to the ground but at a lesser inclination than that required for loading vehicles on to the bed of a lorry.
