Types of Chain Hoists
Chain hoists primarily come in two varieties: manual and electric.
Manual chain hoists function by manually pulling the chain through the hoist’s body, causing the load to ascend. The chain wraps around a toothed wheel, whose teeth securely grasp the chain links, preventing slippage. As the chain is pulled, the wheel rotates, thereby lifting the load.
On the contrary, electric chain hoists are motorized, enabling them to lift heavier loads with greater speed and efficiency than manual hoists. They are commonly utilized in the manufacturing and construction sectors, where precision and swiftness are paramount in lifting and maneuvering heavy loads.
How Chain Hoists Work?
Chain hoists operate based on the fundamental concept of mechanical advantage, allowing a minimal force to efficiently elevate heavy loads. The chain is coiled around a wheel, and as the chain is gradually pulled through the hoist, the wheel rotates, subsequently lifting the load. The extent to which the chain is pulled through the hoist directly correlates to the vertical distance traveled by the load.
Chain hoists are designed with a defined maximum load capacity, representing the safest weight they can handle. Selecting a chain hoist with an appropriate load capacity for the intended task is crucial. Overloading a chain hoist poses a significant risk of failure, potentially leading to hazardous situations.
