Marine Telescopic Knuckle Boom Crane Structure


We not only provide customers with high-quality products, but also provide complete system solutions and high value-added services for specific customers. Therefore, it has strong competitiveness.

Configuration

Part Name

Type/Material

Advantages/Disadvantages

Slewing Bearing

42CrMo

It has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness.

50Mn

The wear resistance, strength, elasticity and hardness are all high, and they are mostly used after quenching and tempering, and the welding performance is poor. Generally used to manufacture parts with high wear resistance and high stress.

S45C

Cold plasticity in general, annealing and normalizing are slightly better than quenching and tempering; annealing and normalizing are slightly better than quenching and tempering; they have higher strength and better machinability; Toughness, plasticity and wear resistance.

Hoisting Winch

A32 & E36

Medium weldability, cold deformation, medium plasticity, good machinability; corrosion resistance.

Q345-B

High strength and good welding performance.

Hydraulic Motor Type

DONGFANG and XINHONG brand

Good quality, cost-effective, long service life. With brake, high safety.

Other brands

High power consumption, relatively poor quality.

Other Parts

Q345-B

Higher strength and better weldability.

A32 & E36

Medium weldability, cold deformation, medium plasticity, good machinability; corrosion resistance.
