Siemens’ site combines a service and repair capability with manufacture of a range of components, including mechanical drives, couplings, geared motors, drive train assemblies, and gear units.
Both manufacturing and assembly of these parts require diverse and complicated component part handling processes before testing and shipping.
For assembling these components in manufacturing cells, Street Crane installed six Street Crane light crane systems, with spans of up to 6m and lifting capacities of 1t, allowing complete access to the space.
It also installed three semi goliath cranes without rails to complete the heavier lifts in the service heavy assembly bay. All of these cranes have lifting capacities of 12.5t. These were installed, Street Crane said, so that operators would not have to wait for a crane to become available.
Two semi-goliaths use tyred wheels and can service the full length of the heavy assembly bay, operating simulataneously without collision owing to the anti-collision system.
In addition, a 25t double girder overhead crane spans the 24.5m bay, using twin Street Crane open winch ZX hoists to provide 12.5t of lifting capacity. Jib cranes are used to move smaller components between processes.
Andrew Pimblett, managing director of Street Crane, said: “Manufacturers like Siemens are seeking a more flexible and comprehensive answers to their handling needs to maximise productivity and return on capital investment. Overhead cranes are still the best way to give whole bay access. However, where there is a need for high frequency transfers at the lower end of the lifting range, then the Street Crane light crane system complements overhead and gantry cranes for maximum efficiency.”
