Considerations for Design and Selection

· Confirm the installation space, stretching stroke, and maximum tensile force parameters
· Select the material based on the environment: Stainless steel for damp outdoor use, carbon steel for ordinary working conditions
· The force direction of the hook should be in line with the assembly to avoid lateral crooked force
· Avoid over-stroke stretching to prevent permanent elongation and failure
· For dynamic and frequent use, heat treatment is required to enhance fatigue resistance
· It can undergo surface treatments such as galvanizing, nickel plating and passivation to prevent rust and corrosion
