Installation & Operation Notes
Overhead mounting must use a support structure rated for the full working load with an appropriate safety factor. A qualified rigger should inspect the top hook connection and ensure vertical suspension. Load attachment requires compatible rigging hardware secured to the bottom hook. To operate, pull the hand chain in the marked direction to raise or lower the load; the mechanical brake engages automatically when the hand chain is released. Pre-use checks should include visual examination of chain links for deformation, hook throat openings, and brake function. Periodic load testing according to local regulations is recommended.
Applications
This manual chain block is suited for manufacturing plants, construction sites, warehouse loading docks, and shipyard maintenance where heavy components must be lifted without power. Its spark-free operation makes it acceptable in environments where electric hoists are restricted. Typical loads include engine blocks, steel coils, concrete forms, and large fabricated assemblies.
