  • FIG. 7 is a plan view thereof.
  • the load carrying platform 10 which may be the base of a container, comprises a rectangular skeleton frame 1 l which may carry a base or floor, not shown, with or without side walls.
  • the forward end of this frame carries two axially aligned rollers 12 and near said end are two front legs 13 hinged at 13a one at each side of the frame so that they can swing upwardly and rearwardly.
  • Each leg is provided with a collapsible strut to retain it in its vertical position, each strut comprising two pivotally interconnected links 14 and 14a hinged to the frame and leg respectively.
  • Each strut has an inwardly projecting pin 14b at the common pivot of the links.
  • the front or leading face of each leg 13 carries two transversely extending rollers 15 and 15a, said rollers being substantially the breadth of the leg.
  • each rear leg 16 hinged at 16a one at each side thereof to swing upwardly and inwardly.
  • Each rear leg has a strut formed of 'two pivotally interconnected links 17 and 17a connected to the leg and to a bracket carried by a longitudinally extending beam 18 of the frame respectively.
  • Also connected at 19d to each leg 16 is one end of a chain or cable 19 which passes under a pin 16b at the common pivot to the two links 17 and 17a, over fixed guide pulleys 19a, over a movable guide pulley 19b and at its other end is anchored to a transverse member of the frame.
  • the two movable pulleys 19b are carried by a horizontally sliding carriage 20 which is supported by a pair of guide rails, not shown, so that it can slide longitudinally of the frame i.e., towards and away from the rear of the frame.
  • the vehicle has a chassis of conventional construction, see FIGS. 1 and 2, that is it has two longitudinally extending side girders 22 interconnected by transverse members and supported by front and rear ground wheels 23 and 24 which are spaced outwardly from the chassis At the front of the chassis is the usual drivers cabin 25.
  • Each girder supports a rail formed of two sections, namely a short rigid rail or ramp section 26 which slopes upwardly from the rear of the cabin and a relatively long rail section 27 which at its forward end is inclined as at 28 to form a continuation of the adjacent short rail and at its rear end forms a downwardly inclined ramp 28a.
  • the two longer rail sections are interconnected by cross members and are pivotally supported at their forward ends by vertical brackets 29 secured to the girders.
  • At the front ends of the shorter rail sections 26 are upright stops 30 having rearwardly extending overhanging abutments 31.
  • the chassis also supports front and rear out-riggers 32 on which are mounted horizontally extending broad rails or runners 33 downwardly curved at their rear extremities to extend over the rear of the rear wheel guards.
  • Towards the rear end of the chassis are two toggles 34 which are spaced apart and occupy vertical planes.
  • the lower link 35 of each toggle is pivoted between brackets 35a mounted on a transversely extending member 35b secured to the girders 22 forming the chassis and the upper link 37 of each toggle is pivoted between plates, not shown, mounted on transversely extending members 35c welded or otherwise secured to the inner sides of the two longer rail sections 27.
  • the upper ends of the upper links carry hooklike members 39.
  • the common pivots of the two toggles are interconnected by means of a cross head 36 which can swivel about the axis of the common pivot of the toggles and is connected by means of two rearwardly extending connecting rods 40 to a slide 41 supported by parallel guides, not shown, rigid with the pivoted longer rail sections 27 and located near the rear ends of the rails.
  • the rear of this slide has an angle iron cross bar 410 to engage the sliding carriage 20 of the platform
  • a double-acting hydraulic ram and cylinder assembly 42 to which pressure fluid can be supplied under the control of valve means, not shown, located in the drivers cabin.
  • the ram is connected to the cross head 36. Carried by the rear Outriggers 32 and further outriggers 32a are trip ramps 32b.
  • the vehicle To mount the platform on the vehicle chassis the vehicle is maneuvered so that its chassis is backed below the forward end of the free standing platform. As the chassis is being backed the rollers 12 at the leading or front end of the platform engage the upwardly inclined ramps 28a at the rear end of the rails 27 of the chassis and the front of the platform is thereby raised. The front legs 13 are therefore raised clear of the ground.
  • the vehicle continues its backing movement until the rollers 12 run on the ramps 26 and abut against the stops 30. Thereafter the hydraulic piston and cylinder assembly is energized under the control of the driver in the cabin to move the cross head 36 towards the rear of the chassis, such movement resulting in the toggle links being straightened and the rear ends of the rails raised as shown in dotted lines in FIG. 1.
  • the rear legs 16 are thus raised clear of the ground.
  • Said toggles also perform two further functions.
  • Their hooklike members 39 engage a transverse member 43 of the platform thereby locking the platform to the rails and through their connecting rods 40 a rearward sliding movement is imparted to the slide 41.
  • a like movement is thereby transmitted by the cross bar 14a to the carriage 20 carrying the movable pulleys 19b.
  • the cables 19 are thereby placed under tension and by bearing on the pins 16b they break the struts of the legs 16. The continued movement results in the two rear legs 16 being raised into their collapsed position.
  • the hydraulic assembly 32 is energized to push the cross head 36 forwardly thereby straightening the toggles.
  • the rear legs then drop to a vertical position.
  • the toggles pass through their dead center the rails are lowered to be supported horizontally by the chassis girders, the rear end of the platform being left supported by the rear legs.
  • the vehicle can .then be driven forward. This results in the rollers 12 running up the ramps 26 and the ramps 28 at the leading ends of the fixed rail sections thus bringing the platform into a substantially horizontal position.
  • a motor driven vehicular chassis and platform combination wherein the platform is provided with rollers at the front end thereof, a pair of front and a pair of rear legs hinged to the platform to swing upwardly from a vertical platform supporting position, releasable struts to maintain the legs in their vertical position and, located towards the rear thereof, a combination of fixed pulleys and movable pulleys and cables or chains passed over said pulleys, the movable pulleys being carried by a sliding member and one end of each cable or chain being anchored to a rear leg and the other end thereof anchored to a fixture and the vehicular chassis is provided with rails pivotally supported at their front ends on the chassis girders and having ramps at their rear end which, when the chassis is backed to a free standing platform cooperatewith the rollers to raise the front of the platform and its front legs, means at the rear of the chassis to release the struts of the front legs, runners to raise the front legs when their struts are released and power means by the operation
  • each strut comprises two pivotally interconnected links having a projecting pin at its pivot and the chassis is provided with trip plates at the rear thereof to cooperate with the pins of the struts of the front legs such cooperation breaking the struts to permit the said legs to swing upwards and the cables or chains pass under the pins of the struts of the rear legs so that when tensioned the struts are broken to permit the rear legs to swing upwards.
