The invention relates to a lifting arrangement for lifting trucks, which lifting arrangement comprises an immovable column in which a movable column with carriage is mounted, these being conncted by block mechanisms to two hydraulic lifting cylinders which are arranged laterally and externally on the profiles of the immovable column. The lifting cylinders 4 are arranged on the upper part of the immovable column 1, above the front wheels 9 of the truck, and are both of the type with a one-side, upwardly acting piston rod, each block mechanism having the ratio 1:4 and consisting of two block plates 7, 8, a side chain 5 and a rear chain 6, which side chain 5 has its immovable end secured on the immovable column 1, is also laid across the block plate 7 mounted on the piston of the lifting cylinder 4 and has its movable end connected to the movable column 2, and which rear chain 6 has its immovable end secured on the immovable column 1, is also laid across the second block plate 8 mounted on the movable column 2, and has its movable end connected to the carriage 3, and the side chain 5 lies in a plane forming an angle with the plane of the rear chain 6. <IMAGE> |
