Shipbuilding Gantry Crane

Shipbuilding gantry crane is one type of gantry crane with large lifting capacity, multiple functions and high efficiency, which is dedicated to transport the subsections of large ship, butt jointing, and overhead turning on dock or shipyard. Ship building gantry crane is perfectly used in ship building port. The crane can be single girder or double girder, single crab or double crab type according to the work requirement. High lifting height and big span make the crane work excellently. The whole crane travels on the rails and powered by cable drum.

Working mechanism:

· Single hanging, lifting hanging, air overturning, air unbalanced tiny turn grievances, such as micro-multiple functions.

· Upper-crab has double main hooks separately situated at the outer side of the main girder which can separate or simultaneously horizontally move within 0-2m.

· Lower crab has main and auxiliary hooks situated below the center of girder.

· The two crabs can mutual act in the air.

· In order to prevent the attacks of storms, there are reliable wind-shielding devices such as rail clamp, ground anchor.

introductions of MEC shipbuilding gantry crane

· Lifting capacity up to 1200on

· Span is 20m to 300m

· Lifting height up to 300m

· Working class: ISOA3/FEM1AM

· crane traveling mechanisms are operated in the driver cabin or remote control

MEC Type Gantry Crane Applied in Shipbuilding factory, this kind of crane is one of gantry crane with large hoisting capacity, multiple

functions and high efficiency, dedicated to subsection transportation of large ship, butt jointing, and overturning on dock or slipway.

1.Both the upper trolley and the lower trolley can cross each other for operation

2.All the lifting mechanism and travelling mechanism adopts frequency conversion speed

3.On the top of the girder at the side of rigid leg is equipped a jib crane to accomplish maintenance of upper and lower trolley

4.In order to prevent the storm attack, such safe and reliable anti-wind devices as rail clamp and ground anchor are equipped

Hengyuan cranes are likely to be involved in the construction, repair and maintenance in the shipyard. For instance, Zhongji Group,

Asia’s biggest shipbuilder uses our cranes extensively with over 20 cranes, many in the 40- 700t range at its various ship and submarine production facilities.
