The VD chain block is a cutting-edge lifting solution designed to enhance productivity and safety in industrial and commercial applications. Developed by Qingyuan Juli Hoisting Machinery Co., Ltd., this product combines advanced engineering with user-friendly design to meet the demands of modern lifting operations. Whether you're working in construction, manufacturing, or logistics, the VD chain block offers a reliable and efficient way to handle heavy loads with precision.
The VD chain block is engineered with several innovative features that set it apart from traditional lifting tools. These features ensure durability, safety, and ease of use, making it a preferred choice for professionals in various industries.
The VD chain block incorporates a double brake structure, which provides precise locking positions and effective stall control. This design ensures stable lifting operations and enhances safety, giving users peace of mind during critical tasks.
Manufactured with a reinforced triangular cover made from thickened alloy steel, the VD chain block is resistant to collisions and corrosion. This feature significantly extends the product's service life, making it ideal for harsh environments.
The streamlined guide wheel of the VD chain block is designed to minimize resistance and ensure smooth operation. An enlarged guide sprocket with a smooth bearing, combined with a derailleur and gear cover that fits the chain, prevents chain jamming and ensures seamless lifting.
The VD chain block features a three-bearing linkage design that replaces traditional gear friction with rolling bearings. This innovation improves rotation efficiency and prolongs the product's service life, reducing maintenance requirements.
The pawl of the VD chain block is crafted from high-strength manganese steel, which is hard, wear-resistant, and fracture-resistant. After undergoing a quenching process, the pawl becomes even tougher, ensuring reliable performance under heavy loads.
The hook of the VD chain block is quenched and refined with an anti-removal lock, making it strong, durable, and resistant to accidental disengagement. This design enhances safety during lifting operations.
The VD chain block is available in multiple models, each tailored to specific lifting requirements. Below is a detailed table of the product's technical specifications:
