Operating the automatic muck skip there is no need for a se- cond operator (just the crane operator) during the loading or unloading process. Due to the dovetail of the beam, the loading and unloading process can be carried out automatically with one rotational movement: the crane operator folds back the lift beam, the dovetail latches, the skip can be loaded. After the loading process, the lift beam unlatches and the skip can be set right. The skip is put to the ground and the lift beam is folded back, latches and interlocks.

By pulling the lift beam up the skip is put into an oblique position and can now unload. The muck skip is put down again, loaded or not, however the lift beam unlocks automatically and can be put into an upright position. With automatic system, therefore automatic unlocking.
