The hook block assembly is the hoisting equipment for oil-drilling rig. It is mainly used to hoist and trip the drill pipe, replace bits, run the casing during petroleum drilling operation by cooperated with crown block, swivel, and elevator ring. It also can be used to eliminate accidents during slight pipe-sticking and touching resistance. The hook block is a combination of traveling block and hook, which shortens the length between the traveling block and the hook. It can work with crown block, swivel, and elevator ring with the same API grade. YG135 hook block features perfect performance, higher mechanization, and safer and more reliable operation.
Product Details:
• Hook Block complies with API 8C standard .
• Joining traveling block and hook together reduces overall length and can help satisfying the requirements of top drive operation.
• The hook block is equipped with the reliable safety devices on the main hook.
• The main parts aire made of high strength alloy steels and are subjected to nondestructive testing.
• The sheave grooves have been intermediate frequency quenched,which can improve the hardness of the surface,the wearness,and the service life.
