Parameter of HOOK BLOCK
The motor driven 360° rotating crane hook block permits the crane operator to use an overhead crane to position heavy or awkward loads in less accessible work areas. They can also be equipped as motorized rotating crane hooks.
Standard non-motorized hook blocks are available for retrofitting or modernization projects. These crane blocks can also be manufactured in larger quantities for new crane installations.
The crane blocks meet all the requirements that apply to lifting operations in countries where the blocks are used. For example, the blocks can be used:
As simple blocks that are mounted onto a crane long-term.
As blocks with speed reeve for quick reeving.
As special blocks with removable ballast parts, which are used primarily in the construction of windmills.
Or as a specialised method that custom work applies to.
1、The hook block is designed and manufactured in accordance with API spec 8C and other related technical standards.
2、 The loaded parts are made of good-quality alloy steel.
The traveling block and the hook block are designed integrally with a miniature size and a compact structure,which is suitable for assembly on the truck-mounted drilling rigs.
