Product description

What is a Telescopic marine knuckle boom crane?
This is our latest multifunctional marine crane, the boom supports telescopic, knuckle, luffing and other functions.
The crane has more lifting points, which can lift the cargo more flexibly. The user assembles it for the marine cargo ship, so we have specially raised the sea state level to reach the standard of the sixth sea state. Can deal with more complex offshore work needs.
According to customer requirements, the Air cooler, oil tank, and electric cabinet pump unit have been treated with waterproof and explosion-proof treatment, which can cope with harsh environments and are more reliable and durable.
