Chain Block

Chain block, also known as hand pulling block, is a kind of popular lifting equipment. It’s features of portable and easy handling are prominent among small lifting machine.

Speaking of the application area, the chain block is employed in factories, mines, power plants, construction sites, farm works, wharfs, shipyards, warehouses and so on. It’s an
excellent instrument for helping you in equipment installation and handling of goods, especially in open-air and no power sites. Chain block can be with manual monorail trolley to form a complete set of a lifting equipment. It applies to monorail overhead carrier, manual operational single beam suspension crane, and cantilever crane.

The main elements of the chain block are made of alloy steel materials. The chain is anti-abrasive and anti-corrosive by adopting 800Mpa high-duty lifting chains with high strength hook, which has been through thermal treatment. The wrought hook design ensure the low speed of the chain block in case of overloading. All of this make the chain block to meet the rules of the European safety standards, namely the CE certification.

The chain block’s advantages lies in its advanced design, high manufacturing techniques, excellent performance, well-formed and compact structure. The reliable and cost effective chain block reduced greatly the labor intensity because of its efficient transmission and easy handling by one person.

Main types:
HSZ chain block, HS-V chain block, HS-VN chain block, HS-VT chain block, HSY chain block, HS-C chain block, QM chain block, VS chain block, KII chain block etc.

General instruction of chain blocks: 
1.It is forbidden to operate the chain block with overload.  
2.We should have a pilot run to check out the components, transmission part, lubrication of the chains before working. Then examine whether the hook is tightened or not. The lifting chains should be arrayed in order in case of the chain might be twisted together during lifting.
3.Manpower is the only acceptable power resources.
4.Ensure no one is under the load when you operate the chain block, in case of any accidents.
5.During the process of operating the chain block, you should keep at a stable speed with same strength no matter you are loading or unloading the weight. Don’t pull the strain abruptly for fear that the chain will get stuck.   
6. Pull the chains in clockwise direction, you can elevate the load, and vice versa.

Tips of maintenance: 

1. Clean the chain hoist,smear it with antirust oil, and them place it in a dry place after use.
2. We need a skilled man for maintenance and repair. Don’t disassemble the equipment without permission.
3.The pilot run is a prerequisite part when you are putting the machine into use. 
4.Keep the friction facing clean, and examine the brake on a regular basis.
