A.T.U Auto-Teile-Unger Handels GmbH & Co KG, headquartered in Weiden, Germany, operates more than 600 branches with adjoining motor-vehicle workshops throughout Europe. In addition, the company trades in automotive accessories, spare parts and tires. A.T.U supplies southern Germany and neighboring countries from its distribution center in Weiden.
Together with the general contractor WITRON Logistik + Informatik GmbH from Parkstein, Germany, DAMBACH Lagersysteme has successfully modernized the automatic high-bay warehouse. WITRON was responsible for the planning, coordination and system integration of the new DAMBACH stacker cranes. The 22-year-old stacker cranes had to be replaced during ongoing operations. Another challenge was the installation situation: Disassembly, dismantling and installation took place via 10m2 windows in the roof.
Precision, teamwork and good coordination of all the project participants were basic prerequisites for this demanding project. Using a crane boom, the old stacker cranes were first of all lifted out in parts. The new DAMBACH MONO type stacker cranes were then gradually introduced into the 28m-high building. The 27m-high mast was inserted pre-assembled into the roof and connected to the truck.Due to their modular design, the single-mast stacker cranes were able to be assembled in the building. This enabled all the stacker cranes to be put back into operation in the shortest possible time.
Downtimes were thus reduced to a minimum and all the 140m-long aisles could be quickly accessed again. The new DAMBACH MONO stacker cranes achieve travel values of 3.5m/s and acceleration values of 0.4m/s² in the logistics center. The lifting speed is 1.0m/s. The successfully-completed modernization will enable A.T.U to continue operating its existing high-bay warehouse economically in the future.
