Let's learn about the crane C-hook
The C-hook is a lifting tool specially used for lifting cylindrical or ring-shaped cargoes. It looks like the letter "C" and is usually made of high-strength alloy steel. It is used to carry steel coils, pipes, tires, large coils, etc.
Main features of C-type hook
Special shape: the opening faces downward or sideways, which is convenient for "hooking" the cargo instead of hooking it like ordinary hooks.
Self-locking function: rely on the dead weight of the cargo to press the inner arc surface to prevent slipping (some models also have spring locks or safety pins).
Strong specialization: mainly optimized for annular/cylindrical cargo such as steel coils and pipes, safer and more efficient than ordinary hooks.
How does the C-hook work?
It looks like the letter "C": It is like a huge steel clamp, with the opening facing downward or sideways, and is specially used to hook circular/cylindrical goods such as steel coils and pipes.
Use gravity to self-lock:
When the C-hook lifts the goods, the weight of the goods will press on the inner arc surface of the hook, and the hook will naturally "clamp" the goods.
The inside of the hook usually has anti-slip grooves or rubber pads to increase friction and prevent sliding.
Use with crane: Connect the crane hook through the top ring or lifting lug, and lift/move the crane to move the goods.
How to choose?
Weight: The rated load of the hook must be greater than the maximum weight of the cargo (for example, if the cargo is 1 ton, choose a hook of more than 1.5 tons).
Shape and size: The width of the hook opening must be greater than the diameter/thickness of the cargo, and the inner arc shape must fit the cargo (for example, a deep arc hook should be used to hang steel coils, and a shallow arc hook should be used to hang pipes).
Look at the working environment:
Temperature: High temperature resistant steel should be selected for high temperature environments (such as steel mills).
Corrosiveness: Select stainless steel or galvanized hooks for humid or chemical environments.
Frequency of use: For frequent use, choose a thickened design or a hook with a bearing (to reduce wear).
Safety function:
Anti-slip design: A hook with a spring lock and a safety pin (to prevent the cargo from falling off when shaking).
Double hook configuration: Overweight or overlong cargo can be lifted and transported in a balanced manner with two C-type hooks.
