Hoists are machines used to vertically lift materials and equipment that are too heavy or
oversized to safely move by hand. If you work in construction, you likely need construction material hoist services to get the job done.
To educate our customers about the hoisting services we have available, we have put together this three-part series on hoist basics. In part two, we’ll explain operation types.
The “operation” of a hoist refers to the power source it uses to provide a lifting motion.
Operation types include manual power, electric power, and pneumatic power.
Manual Powered Hoist
Manual Construction Material hoists are operated by a worker, so they require no external power source. While this requires increased physical effort from your crew, it means the hoist can be reliably hung just about anywhere.
Manually operated hoists are available with a welded link load chain or roller load chain as the lifting mechanism. The hoisting motion is achieved by grasping a continuous hand chain suspended from the hoist and pulling it downward hand-over-hand. The hand chain consists of interwoven formed-welded or unwelded links. As the operator pulls on the chain, the attached wheel or sprocket turns, transmitting motion to the load attached to the chain.
Electric hoists are the most common construction material hoist operation type. They allow for the lifting and lowering of loads at a much faster pace than manual hoists. They also remove strain from your workforce.
Electrically powered hoists are available with a welded link load chain, roller load chain, or wire rope as the lifting mechanism. The hoisting motion is achieved by pressing a button or pulling a lever mounted to the hoist or located on the remote control. This energizes an electric motor, which transmits power to the wheel or sprocket. The load raises or lowers until the operator releases the button or lever.
Pneumatic Power Hoist
Pneumatic (air-powered) hoists are a popular option when electricity is unavailable or cannot be used for safety reasons. They deliver pneumatic power via a compressed air unit, removing strain from your crew, even when electric power isn’t an option.
Air-powered hoists are available with a welded link load chain, roller load chain, or wire rope as the lifting mechanism. The operating method is much the same as with electrically powered hoists—an operator presses a button or lever, and the hoist lifts the load to the desired height.
