The present invention relates to loading equipment comprising a hook-device type arm construction which includes a rear frame, a middle frame, and an angle piece. An upper end of the vertical part of the angle piece is provided with a hook for engaging a corresponding grasping component at the front wall of the exchange platform. The rear frame of the loading equipment and the base construction of the exchange platform are provided with jointly operative locking arrangements for locking the exchange platform onto the loading equipment. The rear frame of the loading equipment is provided with safety catches placed at each side of the rear frame and arranged so that, when the exchange platform is being dumped, they pivot into the locking position, in which they prevent shifting of the exchange platform backwards in relation to the loading equipment, but the safety catches are opened when the rear frame is turned to the horizontal position. The locking arrangements include transverse locking pins fitted to the truck frame and locking levers fitted to the rear frame of the loading equipment with the levers being forced by the exchange platform in the transport position to the open position. The rear frame is secured to the truck frame when the exchange platform rises off the rear frame while the exchange platform is being loaded or removed. |
