Abstract
An aerial tramway having a pair of side-by-side, substantially parallel, movable haul ropes and at least one load carrying unit attached between the haul ropes for advancement therewith. A plurality of detachment assemblies are positioned periodically along the course of the haul rope to detach the load carrier from at least one of the haul ropes and thereby relieve torque induced in the load carrier due to differences in haul rope speeds. The load carrying units preferably have grip assemblies which wedge against the haul ropes, and detachment wheels lift the load carrier unit and grip assemblies up off the haul ropes to effect detachment. A method of conveying load carrying units by side-by-side haul ropes which prevents torque build-up in the units also is disclosed.
