Heavy load transport device for underground mine or tunnel uses transport device moved along monorail via AC motor coupled to hydraulic pump supplying piston/cylinder devices and hydro motors

摘要

The transport device uses an autonomous transport device moved along a monorail, having a hydraulic pump (11) providing the operating energy for piston/cylinder devices and hydro motors, controlling at least one pair of drive wheels and at least one brake cooperating with the monorail. The pump is coupled to an AC motor (10) supplied from a voltage source via a towed cable (19) extending parallel to the monorail.
