15 Aug Product Spotlight: Crane Parts 101 – the small bits
1. HOIST TROLLEYS
Hoist trolleys provide the connection between the lifting device and the bridge. The trolleys are designed for effortless movement along the bridge. The stamped body fits most rigid hook or eye lifting devices.
2. END TRUCKS
End trucks provide the connection between the bridge and runways. They are designed for effortless movement along the runway. For example, in the Gorbel enclosed track system, wheels are tapered to match the 2° taper of the track, which reduces rolling resistance and wheel wear. Wheels contain ball bearings that are sealed and lubricated for life.
4. FESTOON TROLLEYS
Festoon trolleys are used to support flat cable and/or air hose along the runway or bridge much like festoon gliders. Festoon trolleys have four wheels and a pivoting festoon saddle support. Festoon trolleys are used when the track length exceeds sixty feet or in aluminum tracks.
9. FLAT CABLE AND/OR AIR HOSE
Typically, a flat cable festooning system is included in all work station bridge cranes. Enough cable is provided for 3-foot loops on the runway and 1-foot 6-inch loops on the bridge allowing for the entire length and reach of the crane system. An optional air hose is also supported by festoon trolleys.
