Marine Telescopic Knuckle Boom Crane
Application
Marine Telescopic Knuckle Boom Crane is mainly driven by hydraulic motor. With the functionality of both a Telescopic Boom and Knuckle Boom crane, the Marine Telescopic Knuckle Boom Crane can do it all. The Knuckle Boom design gives access to tight spaces and saves deck space, and the Telescopic Boom provides additional reach, giving you unparalleled versatility. One of the advantages of a marine telescopic knuckle boom crane is its flexibility. The telescoping and knuckle sections allow the crane to reach over obstacles and around corners, making it ideal for use in confined spaces on ships or offshore platforms. It is also relatively easy to operate, with most cranes being controlled remotely from a control room or a remote console. However, there are also some limitations to using a marine telescopic knuckle boom crane. Like other types of cranes, it requires a stable base or support to operate safely, and its movement can be affected by the ship's motion in rough seas. It also requires regular maintenance and inspections to ensure safe and reliable operation.
Marine Telescopic Knuckle Boom Crane parts include hydraulic pumps, hydraulic motors, gearboxes, electrical items, wire rope, limit switches, slew rings, joysticks, brakes, crane control cabins, crane control systems, and winches, control valves, potentiometers, hook blocks and sheaves, relays, bolts and more. It is usually installed on the dock or on board for loading, unloading, handling, lifting...
