Siemens improves material flow with crane installation

The Leeds site produces mechanical drives and power transmission components, including geared motors, couplings and drive train assemblies. It also offers a full service and repair facility. Siemens called on Street Crane to help devise a solution to handling problems in its complex manufacturing and assembly operations. For assembly in the high-volume manufacturing cells, six Street Crane one-tonne light crane systems, spanning up to 6m, have been installed. With LX chain hoists and independent gantry support, these provide safe, flexible lifting for lighter loads. Beams and tracks are roll-formed light steel profile sections which are usually attached to existing building structures – but in this case, Street Crane devised floor-standing gantries because of the awkward location within the building. For heavier lifts in the adjoining projects and service heavy assembly bay, three 12.5-tonne capacity semi Goliath cranes have been installed without rails. These ensure that work can be progressed without waiting time for a crane to become available. The heavy assembly bay is also serviced by a 25-tonne double girder overhead crane spanning the full 24.5m width of the bay. Completing the line up, jib cranes in the assembly areas enable smaller components to be handled safely and transferred between processes. Street Crane managing director Andrew Pimblett said: "Manufacturers like Siemens are seeking a more flexible and comprehensive answer 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."
