 SK type chain hoist is a widely used manual hoisting machinery which is easy to use and carry.it can be used in factory, mine, agriculture, electricity, construction site, wharf and dock. And it can also be used in installing of machinery, lifting, loading, unloading in the warehouse, especially suitable to be used in the open air and the place without power source.
 We manufacture the products in accordance with national standard, use the symmetry arrayed two stage gear driven structure. It is design reasonable, dainty material, advanced structure, beautiful appearance, small volume, light weight, big component strength, high toughness, safe and durability. The products has been selling well both at home and abroad. It can compete with well-known brand all over the world.
 Spacing accurate measurement production, effectively avoid the card shell, the chain wrapped together and so on, pulling the chain more smoothly, more easily.
 Chain block cover with alloy steel pressed, with good anti-collision ability to protect the internal structure.
