Manual Chain Hoists: Alloy Steel Construction for Smooth and Safe Lifting
Manual chain hoists are a type of lifting equipment designed for short-distance lifting of small equipment and goods. It operates by pulling the hand chain to raise or lower loads.
The main components of the manual chain hoists are made of alloy steel. The chain is crafted from an 800 MPa high-strength lifting chain, typically made of 20Mn2 material, which undergoes medium-frequency quenching heat treatment for low wear and corrosion resistance. The high-strength hook is usually made of forged alloy steel, featuring a slow lifting design to prevent overloading. The product complies with European CE safety standards.
Manual Chain Hoists come in various types, including round, triangular, and mini models. Based on the material, they can be classified into stainless steel, aluminum alloy, and explosion-proof types. The selection of an appropriate chain block depends on the application scenario, available space, lifting capacity, and lifting height.
Round Manual Chain Hoists
Features
- The side plates are equipped with integrated bearings, and the lifting chain wheel is paired with an integrated bearing design, ensuring smooth operation and reduced hand-pulling effort.
- All internal gear transmission components are made of alloy steel and undergo a rigorous carburizing heat treatment process, enhancing the wear resistance of the gears compared to traditional methods.
- Equipped with two integrated guide wheels, the chain runs smoothly with excellent stability and high strength.
- Features high-strength G80 lifting chains.
