Automated warehouses are offered with completely automated operations for the entry and exit of the products. The need to maximise the use of the available area of warehouses has led to the development of stacker cranes. These machines are designed to work in narrower aisles and at heights of upto 40 metres. Their speed of movement, both horizontally and vertically, along with their automated operation enable handling capacity and pallet extraction to be increased threefold. Stacker cranes are guided from above by a profile fitted on top of the racks, and from below by a guide rail anchored into the floor.
