Equipment for underground collection of waste material

摘要

In the protection position of the protective device (9) the space (1) is screened off, so that with the holder (3) removed the empty space constitutes no danger to the public or personnel. The protective device movement between rest and protection positions is driven by the displacement movement of the holder (3). The protective device is a plate (9) which in the rest position is located on the bottom of the space beneath the holder. In the protection position it is located at the same level as the ground surface. The plate has grippers (10) movable between gripping and freeing positions. In the grip position the plate is coupled with the holder and in the freed position the plate is disconnected from the holder.
