In the lifting and rigging industry, product reliability is built on more than specifications—it must be supported by actual testing. To further verify the performance of our products, Qingdao Haosail Machinery recently conducted a tensile test on our M10 European Type D Shackle with electro-galvanized finish.

The test result demonstrated a breaking load of 32.5 kN, significantly exceeding the minimum requirement based on the product's rated Working Load Limit (WLL), and further confirming the consistency and quality of our manufacturing process.

DIN580 and DIN582 eye bolts are widely recognized as industry-standard lifting points for rigging, hoisting, and lifting operations. Designed according to strict DIN standards, these eye bolts ensure safe, reliable, and durable connections for wire ropes, chains, and other lifting equipment. Choosing the right eye bolt and installing it correctly is essential to prevent accidents, ensure compliance with international safety standards, and optimize lifting efficiency.

What is a Sn**ch Block?

A sn**ch block is a type of pulley block widely used in lifting and rigging operations. It is designed to change the direction of a wire rope or increase pulling force, making it an essential tool in various industrial and commercial applications.

Unlike standard pulley systems, a sn**ch block features a side-opening design, allowing the wire rope to be placed onto the sheave without threading. This design improves efficiency and makes installation faster and more convenient.
