Abstract
The invention relates to a transfer car for heavy loads, a car which has a chassis frame (1) moving on wheels (2) and having a raisable flatbed (3) on top of it, in which an axle (4'), mounted with bearings to the chassis frame and locked to one of the two wheel pairs, is coupled by power transmission means (5') to a transfer motor (6'), for transferring the car, and which additionally has a lever mechanism (7), connected to the flatbed (3), turning on transverse axles primarily in the forward and back ends and coupled to a raising motor (6') by a power transmission (5'), for raising and lowering the flatbed (3). In prior-art transfer cars it has not been possible to exploit the car-transfer mechanism in any way in the load-raising mechanism. Thus the transfer cars for loads such as paper rolls have so far been of a complicated structure and expensive. In the present invention, synergy has been produced between the raising and trasfer mechanisms by fitting the lever mechanism (7) to turn on the axis (4', 4') of the two wheel pairs (2), being freely rotatably mounted with bearings (8) at least on that axle (4') which is locked (9) to its wheel pair (2).
