Usage requirements

Marine cranes are devices and machinery used for loading and unloading cargo by ships, mainly boom devices, deck cranes and other loading and unloading machinery. Marine cranes are a special type of crane that performs transportation operations in a water environment. They are mainly used for important tasks such as the transportation and transfer of cargo between ships, marine replenishment, and the deployment and recovery of underwater operating equipment. The special application environment at sea brings great challenges to the control of marine cranes.

The working characteristics of marine cranes are intermittent movement, and each machine is often in the working state of starting, braking and forward and reverse operation; although its operating speed is not high, it often bears heavy loads; and it works continuously in harsh environments such as dust or seawater moisture corrosion for a long time, requiring the equipment to have the characteristics of high efficiency, continuity, stability, reliability, easy maintenance and long life, and correspondingly puts forward requirements for matching bearings with low speed, heavy load, high reliability and long life.

Product material
The material of the marine crane copper sleeve produced by our company is aluminum bronze 9-4-4-2.
CuAl9Fe4Ni4Mn2 copper alloy has high mechanical properties, excellent corrosion resistance in the atmosphere, fresh water and sea water, high fatigue strength, good castability, good wear resistance, heat resistance below 400℃, heat treatment, good welding performance, and not easy to braze.
ZCuAl9Fe4Ni4Mn2 copper alloy is used for important castings that require high strength and good corrosion resistance, and is one of the main materials for manufacturing ship propellers.
