High Performance Telescopic Boom Marine Crane

Product Description

Product Description

Marine deck cranes are designed for safe and effective loading and unloading of cargo on general cargo ships, container cargo ships, bulk carriers and other transport ships. Marine deck crane is suitable for bulk carrier, container vessel, engineering ships which are voyaging international or domestic.

The hydraulic system of GBM deck crane innovatively adopts a closed system instead of the open system, solving the problem of the lifting brake control, which is rare to see for deck cranes. After successfully applying the closed system of the deck crane, the hydraulic oil consumption has been reduced by more than half compared to the open system deck cranes, and the power consumption has also been greatly reduced. This is a major breakthrough in energy saving and environmental protection. This crane has obtain 6 national patents.

Main Features And Advantages

The availability of a telescopic or fixed jib extension on a telescopic boom is not only easy to attach and use, but it makes it possible to extend the reach of the crane boom by as much as 40 meter. With a jib, boom cranes are capable of reaching boom lengths as tall as 35 meter, which is very beneficial when placing loads at height or lifting personnel by using a basket.

Main features

Highly reliable and safe
Braking system uses both mechanical and hydraulic blocking;
Simple, intuitive mechanical link control system;
Good stability due to sheaves in the center of the jib.
Fast and efficient
Fast lowering speed is kept at highest speed for any load.
Easy maintenance
Simple hydraulic system;
The main equipment is found in a low accessible position of the crane's body;
Sheaves can be replaced easily due to separable bearing housing.
