The VD chain block represents a significant advancement in manual lifting technology, designed to meet the demands of modern industrial applications. Developed by Qingyuan Juli Hoisting Machinery Co., Ltd., this product combines innovative engineering with high-quality materials to deliver a reliable, efficient, and safe lifting solution. In this article, we will explore the key features, technical specifications, and applications of the VD chain block, along with insights into the company’s commitment to quality and innovation.
The VD chain block is an upgraded version of traditional chain hoists, featuring a more sophisticated structure and compact design. Its lightweight construction and improved work efficiency make it an ideal choice for a wide range of industries, including manufacturing, construction, agriculture, and logistics. The hoist is engineered to maintain stable performance and optimal operating conditions even during prolonged use, thanks to its high-quality materials and meticulous craftsmanship.

One of the standout features of the VD chain block is its double brake structure, which ensures precise locking positions and effective stall control. This design enhances safety by preventing unexpected drops and providing users with greater peace of mind during operations. Additionally, the hoist’s thickened alloy steel cover offers enhanced resistance to collisions and corrosion, significantly extending its service life.

The VD chain block incorporates a streamlined guide wheel with an enlarged sprocket and smooth bearings, complemented by a derailleur and gear cover that align perfectly with the chain. This design minimizes resistance and ensures smooth operation, eliminating the risk of chain jamming. The result is a more efficient lifting process with reduced mechanical wear.
Unlike conventional gear systems, the VD chain block utilizes a three-bearing linkage design that replaces traditional gear friction with rolling bearings. This innovation improves rotation efficiency and extends the product’s service life, making it a durable solution for demanding environments.
The pawl, made from high-strength manganese steel, is engineered to be hard, wear-resistant, and fracture-resistant. After undergoing a quenching process, the pawl becomes even tougher, ensuring reliable performance under heavy loads. This feature is critical for maintaining safety and operational integrity during lifting tasks.
The hoist’s hook is quenched and refined with an anti-removal lock mechanism, ensuring it remains secure during use. This design prevents accidental disengagement, adding an extra layer of safety for users and the load being lifted.

The VD chain block is available in multiple models, each tailored to specific lifting requirements. Below is a detailed specification table outlining the key parameters of each model:
