INTRODUCTION
A Manual Chain Hoist (commonly known as a hand chain block or lever block) is a portable, human-powered lifting device. It uses internal spur gears and a load chain mechanism to convert hand-pull force (via a hand chain loop or ratchet lever) into mechanical advantage, allowing an operator to lift, lower, or tension heavy loads without electricity.
APPLICATION SCENARIO
[1] Construction sites – Lifting materials, tools, and equipment in remote areas without electricity.
[2] Warehouse maintenance – Hoisting heavy spare parts or machinery during installation.
[3] Shipyards and docks – Tightening and positioning heavy components on vessels.
[4] Factory maintenance pits – Raising pumps, motors, or gearboxes for repair.
[5] Mining and field operations – Lifting equipment in explosive environments (non‑sparking version available)

ADVANTAGES
[1] No power required – Operates anywhere, ideal for remote or outdoor sites.
[2] Low cost – Affordable purchase and zero energy consumption.
[3] Simple and durable – Mechanical design with minimal maintenance.
[4] Precise load control – Hand chain allows fine positioning.
[5] Portable and lightweight – Easy to carry and rig in different locations.
