Product Description

Telescopic Knuckle Boom Marine Crane

OEM & ODM
Certificate: ABS, BV, CCS, DNV, LR, NK, RS, ISO9001, CE
Slewing angle range: 0-400°

The telescopic knuckle boom marine crane, also known as an electro-hydraulic telescopic foldable boom crane, is a new type of lifting equipment that uses an electric-powered hydraulic system.
The telescopic knuckle boom marine crane's jib can both telescope and fold, offering stable performance, high efficiency, and excellent performance.
This marine crane has a lifting capacity of up to 5+ tons and a working radius of up to 25+ meters. With a compact footprint, the crane can be delivered as a complete unit.

Features:

Telescopic folding cranes are compact and can be easily installed on all types of vessels; the contraction and folding of the lifting arm makes them light and flexible, taking up little space, and with a large lifting capacity and a wide range of working radius.

Applications

Collapsible telescopic boom cranes are particularly suitable for use on ships, oil rigs, and other offshore platforms where space is limited and heavy lifting is required.

Design Drawing

We can design and produce cranes according to the operational scenarios and specific requirements, accept non-standard customization, and customers can also choose the required functions according to their requirements.
