Advantages/Disadvantages

Drum

Q235-A

It has good toughness and plasticity, has a certain elongation, and has good weld-ability and hot work-ability. Q235A is generally used in the hot-rolled state. CCS no longer needed Q235A.

Q235-B

Has a certain elongation, strength, good toughness and cast-ability, easy to stamp and welding. Suitable for products with small loads.

Q345-B

Good comprehensive performance, good low temperature performance, good cold stamping performance, good welding performance and machinability. (High strength, good welding performance).

Gypsy Wheel

Q345D

It has good comprehensive mechanical properties, good weldability, cold and hot workability and corrosion resistance, and has good low temperature toughness (high strength, good welding performance).

Consequence

Drum

To reduce costs, reduce the thickness of the drum.

The thickness of the drum is too thin, which is not conducive to the load and wears quickly.

Produced in strict accordance with product production standards, with moderate thickness.

The thickness is moderate, which is good for loading, wears slowly, and does not cause the product to be too heavy to increase the transportation cost.

Gypsy Wheel

Cast iron

Cast iron has good casting performance, but when the carbon content of cast iron is relatively high, its performance is relatively brittle, and its tensile performance is relatively poor; it is easy to corrode and wear quickly, which is not conducive to load.

Q345D

The Q345D steel plate is preheated before welding to prevent the occurrence of cold cracks. And Q345D has good cold and hot working properties and corrosion resistance, and has good low temperature toughness. Conducive to load, slow wear.

Pedestal

Q235-B

Low strength, suitable for products with small overload; Used for heavy loads winches, wear out quickly and break easily.

Q345-B

Higher strength, slower wear, not easy to break, suitable for both small and large load winches.
