Offshore Hydraulic Straight Arm/Boom Marine Deck Crane
The offshore hydraulic straight boom crane has a fixed boom length. Driven by electric hydraulics, the crane can perform 360-degree
full rotation and luffing up and down to change the lifting height.
The deck cranes installed on ships can load and unload goods and containers in marine environments.
They are simple to operate, safe and reliable and can withstand long-term working and idle states. Full consideration has been
given to maintenance, technology, and design, making maintenance easy and minimizing maintenance volume and downtime.
The deck cranes are of high quality and flexible when loading and unloading. In addition, sufficient consideration has been given to
weight reduction and space restrictions.
