Continuously installable/removable collector trolley |
摘要 |
A continuously installable/removable collector trolley includes a plurality of selectively extendable and retractable bearing assemblies. The bearing assemblies may be retracted to permit insertion and removal of the trolley into a conductor bar track at any point along the track. The bearing assemblies may then be extended to secure the trolley within the track, and to permit the bearings to roll along the track, permitting movement of the trolley.
