Equipment for loading an exchange platform onto a vehicle includes a rear frame pivotally mounted to the rear of the vehicle and a middle frame pivotally mounted on the rear frame. An angle piece has a horizontal portion pivotally mounted to the middle frame and a vertical portion with a grasping device at its upper end. A cylinder for operating the loading equipment is connected between the vehicle and the middle frame. In addition, a link arm and/or a second cylinder is provided between the vehicle and either the rear or middle frames to enable the exchange platform to be raised above the vehicle in a horizontal position.

Equipment for raising an exchange platform or container to a horizontal

Loading equipment which is suitable for loading exchange platforms of two different platform frame widths onto a truck chassis or dumper frame and for unloading the exchange platforms from same. The loading equipment comprises a locking mechanism for securing the exchange platform onto the frame of the loading equipment automatically in connection with the pulling-on step of the exchange platform. The rollers at the rear end of the truck are wide enough that the inner ends of the rollers are suitable for a rolling base of the frame beams of exchange platforms with narrow platform frame width and the outer ends of the rollers are suitable for a rolling base of the frame beams of exchange platforms with wide platform frame width. The platform locking mechanism of the loading equipment is located in the center planes perpendicular to the rolling surfaces, i.e. cylinder faces, of the rollers in the rear part of the truck, whereby the locking mechanism is outside the frame beams of exchange platforms with narrow platform frame width but inside the frame beams of exchange platforms with wide platform frame width, i.e. between the frame beams.

Loading equipment

Apparatus for loading a container onto a truck or trailer, and for dumping the container, includes a first frame pivotally attached to the rear of the truck or trailer and a second frame pivotally mounted on the first frame. An L-shaped member is pivotally mounted on the second frame, and its pivotal movement is controlled independently of the pivotal movement of the two frames by a piston and cylinder arrangement. The path of movement of the grasping end of the L-shaped member is twice the length of the section of the member that is connected to the second frame, to enable different sized containers to be transported and dumped in different positions on the truck or trailer.
