Structural design features of hand chain hoist
NingBo Jiangdong Tianye Rigging Co, Ltd., as a Chinese rigging and lifting equipment manufacturer, has won wide recognition in the global market for its excellent product quality and innovative design concepts. The company is committed to providing customers with high-performance and high-safety lifting equipment to meet the needs of various industrial applications.
Structural design overview
Hand chain hoist, also known as chain hoist or chain hoist, is a manual lifting machinery that is easy to operate and carry. Its structural design has been carefully considered and is mainly composed of several core parts such as sprocket, hand chain, transmission mechanism, lifting chain and upper and lower hooks. The precise coordination of these components ensures that the hand chain hoist can achieve efficient and stable lifting operations in a variety of complex environments.
Core component design features
Sprocket and hand chain:
The sprocket of the hand chain hoist is made of high-strength alloy material, and the surface is specially treated with excellent wear resistance and corrosion resistance. The scientific design of the sprocket not only ensures the smooth operation of the chain, but also effectively reduces the wear of the chain during operation, thereby extending its service life. The hand chain is made of high-quality steel with a polished surface, which is comfortable to the touch and easy to operate. The length and diameter are carefully designed to provide sufficient pulling force during operation while reducing the operator's fatigue.
Transmission mechanism:
The transmission system of the hand chain hoist usually adopts gear transmission or worm gear transmission. Due to the low efficiency and easy wear of worm gear transmission, modern hand chain hoists prefer gear transmission. This transmission method has the advantages of high efficiency, compact structure and easy maintenance, which can ensure the stable performance of the equipment in long-term use. In addition, the design of the gear transmission system also takes into account noise control and lubrication issues. The use of precision-machined gears and high-quality lubricants effectively reduces the noise and friction during the transmission process, and improves the reliability and durability of the hand chain hoist.
Lifting chain and hook:
The lifting chain is one of the key components of the hand chain hoist. Its quality and performance are directly related to the safety and efficiency of the lifting operation. The high-strength lifting chain produced by NingBo Jiangdong Tianye Rigging Co, Ltd. has a tensile strength of more than 800Mpa, ensuring that it will not break or deform when carrying heavy objects. The hook is designed with forging technology and has the characteristics of high strength and low wear. The opening part of the hook is specially treated to ensure that it will not be damaged by friction during the lifting process. In addition, the hook is equipped with a safety lock device to effectively prevent accidents caused by accidental falling off during the lifting process.
Safety protection device design
The safety protection device of the hand chain hoist is a highlight in its structural design. In order to ensure the safety of the lifting operation, the hand chain hoist is equipped with multiple safety protection devices, including overload protection, sprocket limit and brake. These devices can monitor abnormal conditions during the lifting process in real time, respond quickly and take corresponding measures to effectively prevent accidents.
