The 3-tonne 17m telescopic boom offshore crane is an efficient and reliable lifting equipment indispensable in modern offshore engineering. Its unique structural design and excellent performance make it widely used in ships, harbors, offshore platforms, and other fields.

Product structure features
The 3-tonne 17m telescopic boom offshore crane consists of a foundation structure, telescopic boom, slewing mechanism, hydraulic system, and control system. The foundation structure is sturdy and durable, providing support for the whole equipment; the telescopic boom adopts a multi-section jib design, which can be adjusted in length according to the operational requirements; the slewing mechanism ensures that the equipment has a 360-degree rotating range; the hydraulic system provides power for the crane's movements; the control system realizes precise control of the equipment.
Performance Advantage
This crane has many advantages such as large tonnage, long boom spread, flexible operation, safety and reliability, corrosion resistance and so on. Its large tonnage and long boom span enable it to cover a wider working range and meet various operational requirements; the precise design of the hydraulic system and control system makes it flexible and easy to control; multiple safety protection devices ensure operational safety; and corrosion-resistant materials enable it to adapt to the harsh marine environment.


Application areas
The 3-tonne 17m telescopic boom ocean crane is widely used in ships, ports, and offshore platforms. In ships, it can be used for cargo loading and unloading, material handling, and other operations; in ports, it can be used for container loading and unloading, bulk cargo loading and unloading, and other operations; in the ocean platform, it can be used for equipment installation, maintenance, and other operations, providing strong support for the construction of marine engineering.
As an efficient and reliable lifting equipment, the 3-tonne 17m telescopic boom ocean crane plays an important role in offshore engineering. With the continuous progress of technology, this type of product will be more widely used in the future, and make a greater contribution to the development of marine engineering.
