Support frame suspension track conveyor - has unit combining two hoist carriage assemblies, linked by traverse on parallel rails

摘要

The suspension track for conveying completely assembled long-wall support frames in a mine has two hoist carriages with hoist equipment, coupled together for travel on an overhead rail. The carriages are firmly coupled at a given spacing and have a carrier beam connected to their hoist equipment. Two such carrier beams are coupled by a traverse to form a conveyor unit travelling on two rails close together, with accommodating retainers for a support frame. The traverse may be connected to the beams by a three-point hitch.
