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
Used in areas without power supply, construction sites, warehouses, workshops, and maintenance shops. Ideal for lifting and pulling small to medium loads in remote or outdoor environments.
ADVANTAGES
No Power Required: Operates entirely manually, suitable for any location.
Portable & Compact: Lightweight design makes it easy to carry and install.
Highly Reliable: Simple mechanical structure ensures safety with a reliable ratchet brake system.
Cost-Effective: Low initial investment and minimal maintenance costs.
Durable: Built with high-strength steel and anti-corrosion chains for long-term use.
