2 All rights Drive Basics R0101. page 6 Tower Crane A tower Crane is often transportable and will be built on site This type of Crane is light therefore all Crane components should be light Drives, motors and gearboxes are at the top of the tower Small cranes are typically driven by AC motors Small and simple control concept Copyright 5/29/2009 ABB. All rights Drive Basics R0101. page 7 Single Trolley Crane (Ship to Shore) Classic harbor Crane The trolley transports container from ship to shore The hoist sometimes has a double motor configuration Shared motion between hoist gantry or trolley boom Smooth brake control reduces damage to goods High voltage supply cable Anti Sway Control Copyright 5/29/2009 ABB. All rights Drive Basics R0101.

All rights Drive Basics R0101. page 9 Rail Mounted Gantry Crane (RMG) Specialized yard container handling machines for 20 foot or 40 foot containers The railway Crane is used to transport containers in a railway terminal The Crane moves on rails in one direction and the trolley in the other Copyright 5/29/2009 ABB. All rights Drive Basics R0101. page 10 Rubber Tire Gantry Crane (RTG) The RTG Crane travels on tires The gantry is also equipped with steering This type of Crane needs a level area for operation Powered by diesel engine Copyright 5/29/2009 ABB.
