A Brief Discussion on the Differences of Ship Crane Pulleys

The lifting pulleys widely used in engineering lifting operations can be divided into two types based on the lifting environment: one is our manufacturer's ordinary lifting pulley, and the other is the marine lifting pulley. The work content of the two types of lifting pulleys is generally the same, but due to different working environments, there are certain differences in their external structure and metal properties.

Marine lifting tackle is mainly used for offshore lifting operations, so it has the characteristics of corrosion resistance, impact resistance, wear resistance, and large load capacity. The differences between marine tackle are as follows.

① The design of the marine crane pulley has added a protective plate, which has better sealing and greatly improves the impact resistance of the marine crane pulley.

② The shell of the marine lifting pulley is more sturdy, safer, more corrosion-resistant, and has a longer service life.

③ Some ship lifting tackle are made of wooden material, which effectively avoids the problem of metal rusting, but the load is slightly lighter.

This is the difference between marine lifting tackle, and it is also the different design schemes made by designers based on the different operating environments of lifting tackle. This enables different lifting tackle to play their own strengths in different operating environments.
