Abstract
1,250,630. Masted lift trucks; fluid pressure apparatus acting through ropes or chains. DECINSKE STROJIRNY. 11 Nov., 1968 [9 Nov., 1967], No. 53390/68. Headings B8B and B8H. The mast assembly of a lift truck includes two hydraulic rams of unequal length mounted on the fixed mast section 1. The piston-rod 18<SP>1</SP> of the long ram 6 is secured to the movable mast section. A rope or chain 10, secured to the short ram cylinder 5 at 51, passes over a pulley 7 on the piston-rod 17<SP>1</SP>, under a pulley 8 on the cylinder 5, and over a pulley 9 on the piston-rod 18<SP>1</SP> to an anchorage 31 on the lifting carriage 3. The rams are arranged so that the axes of pulleys 7, 8 are substantially perpendicular to the axis of pulley 9, Fig. 5 (not shown). In operation, fluid is supplied to both rams simultaneously and the ram 5 extends until the lifting carriage reaches the top of the movable mast section. The ram 6 then starts to extend to raise the movable mast section together with the lifting carriage. As the ram 6 extends, the ram 5 is caused to retract, Fig. 4 (not shown).
