The seven ton locomotive crane is a self propelled rail-mounted steam crane in the form of a tank locomotive. It has a swivelling non-winch jib which operated with three separate hooks.
The jib is 21 ft 9 inches (6.63 m) in length and is tapered in design and constructed of steel plate. The outer hook at the end of the jib could lift 3½ tons, the centre hook at 16 ft (4.88 m) along the jib could lift 5 tons and the closet hook at 12 ft (3.66 m) could lift 7 tons. The long jib is acitvated via a steam cylinder and piston arrangement and has a 3 ton counterweight balance weight. It can be rotated under its own power to pick up material next to and around the crane locomotive. When the jib was in the forward position, a hole in it allowed smoke from the chimney to escape.
