Device for improved loading of a heavy object on a sliding platform

The device (1) has two actuators (8) adapted to accompany displacement of the device on a floor (2) of a loading body of a vehicle from a retracted position inside the vehicle to an extracted position outside the vehicle. The actuators are designed as gas springs, which are placed approximately vertically on sides of the device, where the device is held at a front end by the gas springs. Lateral sides of a back portion of the device are equipped with two sets of rollers (6, 7), which move in rails that are fixed on the floor.
