Hand pulled hoist, also known as immortal hoist, chain hoist, reverse chain or manual hoist, is a simple to use and easy to carry manual lifting machinery suitable for short distance lifting of small equipment and goods
1. Working principle
Hand pulled hoists achieve labor-saving effects through gear sets. When pulling the bracelet clockwise, the bracelet wheel drives the friction plate and ratchet wheel to rotate, transmitting force to the lifting sprocket and causing the heavy object to rise; When the pulling stops, the pawl engages with the ratchet to achieve automatic braking. When pulled counterclockwise, the friction plate releases and the heavy object can smoothly descend
2. Main features
Safe and reliable: using a ratchet friction plate one-way brake, it can self brake under load
1: Lightweight and durable: The shell is made of high-quality alloy steel, and the chain has been quenched for corrosion resistance and high strength
2: Widely applicable: especially suitable for outdoor and non power environment operations, such as factories, docks, construction sites, etc
3: Operation precautions
It is strictly prohibited to use diagonally or overload
When operating, stand in the same plane as the bracelet wheel and apply even force
Clean and apply rust proof grease after use, store in a dry place
