Monorail electric travelling trolleys – commonly known as Electric trolleys operate on a single rail, often referred to as a monorail, and are maneuvered by electric motor and control panel operated by a pendent push button. When operator presses the button – motor is provided power supply which activates a system of gears which in turn propels the trolley wheels along the beam. This allows for faster movement, making it possible to maneuver heavy materials with ease and stability. They are particularly useful in environments where space is at a premium, as the monorail system requires minimal clearance and can be installed overhead, leaving valuable floor space free for other operations.
The versatility of monorail systems is further enhanced by their ability to incorporate features such as curves, switches, and turntables, which can connect to other material handling systems like overhead bridge cranes or conveyors. This makes them an adaptable solution for various industrial processes. Moreover, the electric monorail conveyor systems are particularly beneficial in automated warehouses, where they can move pallets along a closed circuit of electrified rails, connecting different areas quickly and efficiently.
Some trolleys employ a mechanically positive drive system that travels along the rail, incorporating an overspeed and secondary brake to prevent uncontrolled movement, especially down an incline. Electric power to these trolleys is typically provided via a busbar system located adjacent to the monorail, ensuring a consistent and reliable power supply.
