LIFTING DEVICE FOR LATERAL DISPLACEMENT OF THE TRAILING END OF ROAD VEHICLES

摘要

A lifting device for lifting the trailing end of a road vehicle and use d to laterally displace the same. The lifting device includes a main body including a fixed section rigidly secured to the trailing end, a first mobile section essentially vertically movable along the fixed section between an elevated non-operative position and a lowered operative position lifting the trailing end, and a second mobile section being essentially rotatably mounted onto the first mobile section. The lifting device also includes a linear actuator device to linearly move t he first mobile section onto the fixed section, a rotary actuator device to rotatably move the second mobile section from the first mobile section, a rolling device pivotally free mounted to the second mobile section to rollingly engage a road surface , a blocking mechanism to temporarily block the rotary actuator device from rotating when the lifting device is in operative position, and a power source to activate both actuator devices.
