  • the support structure may comprise a base or floor on the chassis of a vehicle.
  • the operating arm lies substantially horizontally below, or within, the chassis and is movable in a longitudinal direction by a manually or pump-operated hydraulic jack or a mechanical screw jack.
  • One end of the link is preferably connected to the rear ⁇ ward, or other end of the operating arm.
  • the lifting arm is hingedly mounted on the vehicle chassis or support structure adjacent its lower or rearward end.
  • the link being preferably connected to that end.
  • the distal or free end of the lifting arm has a roller which bears on a track or guide on the underside of the load or body.
  • two operating arms, lifting arms and links may be provided, the jack operat ⁇ ing against a yoke interconnecting the operating arm.
  • the mechanism may be provided with an auto ⁇ matic locking system including: first locking means to releasably secure the lifting arm to the load body when the load body is in its lowered position; and second locking means on the operating arm releasably engagable with a stop on the chassis when the operating arm is moved axially by the lifting arm as the load body moves from its lowered position but free to pass the stop when the lifting arm is moved axially by the moving means to raise.
  • the lifting arm and the load body . . ...
  • the first locking means includes a plate or loop mounted on the load body which engages the underside of the lifting arm when the load body is in its lowered position.
  • the second locking means includes a locking plate or finger on the underside of the operat ⁇ ing arm which is free to pass over a stop in a guide, for the operating arm mounted on the chassis , when the operating arm is moved axially by the jack.
  • the lifting arm pushes the rear end of the operating arm downwardly as it pushes it forwardly and the locking plate or finger engages the stop to prevent further movement.
  • the present invention resides in a lifting mechanism for a load wherein: the load is slidably mounted on substantially vertical guides; a lever is hingedly mounted at one end on the support structure and is connected at its other end to the load by a link member; and the one end of the lifting arm of the tipping mechanism hereinbefore described, engages the lever intermediate its length to raise or lower the lever and thereby the load.

  • FIG. 10 is a side view of a fifth embodiment showing a load e.g. a building, iftting with the mechanism as levelling jacks;
  • FIG. 11 is a side view of a sixth embodiment showing the mechanism used as a high-lift trolley jack for vehicles .
  • the trailer 10 has a chassis with a pair of side rails 11 interconnected by front and rear cross-beams 12, 13.
  • a drawbar 14 has a towbar socket 15 and the trailer is supported on pneumatic tyres 16 which has an axle 17 mounted on leaf springs 18 under the side rails 11.
  • a tipping load body 19 is hingedly mounted at its rear end on the chassis and is provided with a hinged tailgate (not shown) .
  • the tipping mechanism 20 is mounted between parallel beams 11a parallel to the side beams 11.
  • An operating arm 21 which extends substan ⁇ tially horizontally along the centreline of the chassis is supported by bolts 22, 22a, mounted between pairs of side plates 23, 23a under slung from parallel side beams 24 bolted between the beams 11a of the trailer.
  • the operating arm 21 has an upward extension 25 which is engaged by the ram 26 of a hydraulic vehicle jack 27 which has its base plate 28 mounted on a mounting plate 29 between the side beams 24.
  • the base plate 28 is secured to the mounting block by a spring-loaded bolt 30.
  • the lifting arm 31 is hingedly mounted, inter- mediate its length, between a pair of side plates 32 on the side beams 24.
  • a roller 33 is rotatably mounted at the distal end of the lifting arm to bear against a track 34 fixed to the underside of the load body 19.
  • a link 35 is hingedly connected to the rearward ends of both the operating and lifting arms 21, 31.
  • a mechanically-operated hydraulic ram 27 While a mechanically-operated hydraulic ram 27 is shown, the ram could be powered by a small hydraulic pump electrically driven from the towing vehicle or the ram could be replaced by a mechanical screw-jack.

Abstract

Un mécanisme de basculement (20) comprend une paire de poutrelles latérales parallèles (24) montées dans le châssis d'une remorque. Un bras d'actionnement (21) est placé en appui entre des plaques de guidage (23, 23a) et se déplace longitudinalement sous l'action d'un piston hydraulique (27). Le bras de levage (31) est monté par charnière sur des plaques latérales (32) et comporte à son extrèmité distale une roulette (33) destinée à se placer en prise avec un rail situé sur la face inférieure d'une charge montée par charnière sur le châssis. Un organe de liaison (35) relie entre eux le bras d'actionnement (21) et le bras de levage (31), de sorte que le bras d'actionnement (21) se déplace sous l'action du piston (27) et le bras de levage (31) s'élève ou s'abaisse en deux phases, l'organe de liaison (35) pivotant autour d'un boulon (36) placé sur le bras d'actionnement (21). Les modifications permettent d'utiliser le mécanisme dans un cric mobile et d'obtenir une élévation verticale rectiligne d'une charge en employant des guides verticaux.
