Product Description

Knuckle boom crane is a kind of special purpose crane to carry out transportation operations in the maritime environment. They are mainly for the transportation of goods between ships, the supply of sea, the delivery and recycling of object during underwater operations. Our hydraulic system 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.

Main Features and advantages:1. Built-in machine, electric, hydraulic, integrated system.2. Fully hydraulic drive.3. Self-diagnosis wave compensation system.4. Luffing load horizontal movement technology.5. Multiple safety devices including torque limiter, etc.6. Visible safety monitoring system.
