A chain hoist is a part of a block and tackle system that has multiple chains running through it. It creates mechanical advantage by using artificial leverage to lift heavy objects with little effort. A chain hoist is the name of the portion of a block and hoist around which the chain wraps. By itself, […]
A pulley hoist is a device used for lifting heavy objects, consisting of one or more pulleys and a hook or safety system. It can be manually or motorized, and is commonly used in industrial environments, garages, and workshops. The user pulls the rope or chain to activate the pulleys, and a motorized hoist is […]
A jib hoist, also known as a jib crane, uses a boom and pulley system to lift and move heavy objects. It features a pulley system with wire ropes, chains, or belts, and is commonly used for industrial and domestic applications. The hoist has a vertical beam for stability, a horizontal arm for load distribution, […]
The pulley is a simple machine that reduces the force needed to lift an object by distributing its weight across multiple points of contact. A rope hoist consists of a grooved wheel, casing, and attachment point. A block and tackle is created when multiple sheaves are used together. More complex hoist systems can produce higher […]
A gantry hoist is a hoist with a trolley that moves along a beam for vertical and horizontal lifting. They are used in warehouses, docks, and manufacturing environments and can be hired for temporary use. They can be installed using fixed or moving beams or structures on legs. Operators can control the hoist remotely or […]
A pump hoist is a device mounted on a truck used to replace submersible pumps and well pipes. It consists of a tower with a pulley, a hoist, and a cable. The hoist lifts the pump out of the well casing for maintenance, and the pump is reconnected after repairs. The size of the hoist […]
A chain hoist is a mechanical device with pulleys used to lift heavy loads. The history of pulleys dates back to ancient times, with Archimedes credited with inventing a pulley system to pull ships out of the sea. There are three types of chain hoists: pneumatic, manual, and electric, with the latter used for lifting […]
When repairing a hoist, always turn off the power and wear protective gear. Repairs should be done in pairs, and the cable and hitch fixing bolts should be checked for damage. Note any potential problems for future repairs. One tip when making hoist repairs is to always be sure to shut off power to the […]
Hoists have many hidden parts, including the drive motor, hooks, and lever locks. Critical parts include the safety catch, operating handle, and mounting bolts. Air-operated hoists require line filters to prevent damage. Hoists are used to move heavy objects in manufacturing facilities, and critical parts include the control panel and drive motor. Water strainers and […]
A four post hoist lifts vehicles off the ground for repairs using an electric motor and cables. It is easy to install and safe, but tires cannot be removed once lifted, and power outages can be an issue. It can be used indoors and outdoors. A four post hoist is a device found in many […]
Drywall hoists are devices used in construction to hold and position drywall sheets for installation on walls or ceilings. They save labor and come in light and heavy grades. Drywall is a plaster layer between two thick paper sheets used to make walls and ceilings, but it is heavy and awkward to work with. Drywall […]
An electric chain hoist uses an electric motor to drive a series of gears that pull a chain up or down. Chain drops can be added to lift heavy objects with minimal effort. It is not recommended for horizontal traction and can be used to transport heavy objects across a building. An electric chain hoist […]
Lever hoists are portable lifting devices that use manual operation to lift heavy loads. They come in two main categories: rope/wire rope hoists and chain hoists. Both types use a ratchet and pawl system to lift loads, and can be used for lifting, tensioning, or pulling operations. Wire rope hoists are ideal for horizontal pulling […]
A wire rope hoist, also known as a block and tackle, consists of a single rope running between two sets of sheaves in a large block, increasing lifting force. Originally made with wooden blocks and hemp rope, modern versions use metal blocks and nylon rope. The hoist can be used for vertical lifting and horizontal […]
Electric hoists lift and lower objects vertically and can move horizontally when attached to hardware. They use an electric motor and can be hardwired or driven by a generator. Hoists can use chain or rope and are rated by weight. Some hoists are designed to move across horizontal space. They are operated with a remote […]
