Where there's the need to lift, lower and move heavy items horizontally within the workplace or worksite, hoists are the industry standard equipment. They can safely handle items weighing several tons, come in different load capacities and offer safety, efficiency and flexibility to deal with different loads. They're used in obvious work environments like construction and mining sites, automotive workshops and freight yards.

Essential Equipment For Your Lifting Needs

In simple terms, a machinery hoist is a mechanical device that raises, lowers or suspends heavy equipment using an assembly of chains, wire or rope, a lowering hook, and a lifting and lowering mechanism. The whole assembly is suspended from a crane or beam via an upper hook and safety latch. The lifting and lowering mechanism is housed in a hoist frame and can be manually, electrically, hydraulically or pneumatically powered, leading to different types. 

Common Uses 

•  Lifting - hoists lift loads vertically. Items are attached to hooks fitted with safety latches at the end of the chains or heavy-gauge wire, wrapped around a drum or wheel. Depending on the load capacity of the lifting mechanism, a machinery hoist handles loads weighing anywhere between 80 kilos to 100 tons. 
•  Lowering - use a hoist to lower heavy loads to the required heights. Chains, rope or wire and the lifting/lowering mech work varying and geared lowering speeds for optimal safety. 
•  Suspending loads - construction sites and manufacturing plants often require heavy building materials and equipment to be suspended for longer periods, for instance during inspection or in assembly lines. 
•  Pulling or dragging - some hoist types can additionally be used to pull exceptionally heavy loads along a horizontal axis, for instance, a girder or beam.

Types

Manual  

Manual hoists deploy wire, rope or chains that lift or lower items by cranking a lever or pulling a hand chain to engage gears to lift or lower the load chain. They're designed for smaller loads but offer portability, can be used in settings with no power supply and require little to no maintenance.

Manual hoists are also the most affordable type, won't incur high costs during repairs and the compact footprint means they're ideal for smaller workshops or home use. 

Electric 

These are powered by electric motors (in varying power output) and control panels or pendants to power the hoist on and off, raise or lower the load, and adjust speeds. They offer higher safety and more control than manual hoists when moving heavier items. Depending on the lifting medium, there are three common types: 

•  Chain hoists - these use heavy-duty load chains in lifting and lowering tasks. They're found in workshops, warehouses and smaller manufacturing settings, and able to lift or lower items weighing up to 5000 kilos. 
•  Wire rope - these consist of a central steel wire core and multiple wire strands, with thicknesses generally ranging between 10 and 25mm and lifting capacities up to 50 tons. Common uses are in construction, mining and material handling. Design variations include standard and low headroom wire rope machinery hoists, and stationary types limited to lifting and lowering. 
•  Belt hoists - belts made of strong synthetic fibres offer increased durability and safety in areas like food processing, the aerospace and pharmaceutical industries.

Choose electric hoists for their affordability (compared to other lifting alternatives such as cranes, forklifts or hydraulic hoists), generally quiet operation, fast lifting speeds and versatility with different loads and settings. 

Hydraulic 

Hydraulic hoists use hydraulic pressure in fluid that is pushed by pumps and sustained in cylinders. Pumps pressurize the fluid and push on cylinders to supply the correct lifting strength. They're a common feature of auto repair shops, where they can lift vehicles of varying size or weight. This is supported by hoists sitting on two or four posts. 

Hydraulic hoists offer stable lifting and lowering for increased safety. And like manual types, they require little or no maintenance, meaning lower operational costs than electric types with comparable lifting capacity. 

Pneumatic or Air Hoists

Air or pneumatic hoists are powered by compressed air. There are three types. Pneumatic chain hoists use a load chain and have proven to be durable, reliable and suitable for different uses. Wire rope hoists powered by compressed air are known for their faster operating speeds and reduced spark risk. While larger piston types deal with higher loads and linear lifting and lowering. 

Common uses are in construction, mining, shipping, oil extraction, the chemical and food industry and more. They will require higher purchasing and maintenance costs than other hoist types but offer improved safety, longer duty cycles without overheating (like electric hoists), and the ability to work outdoors and in any type of weather. 

Key Factors to Choosing the Right Hoist

Have in mind several key considerations when choosing the right machinery hoist. 

•  Load capacity - this refers to the safe weight loadings (in kilograms or tons) the hoist can lift and lower without incurring damage or jeopardizing workplace safety. Manual types understandably have the lowest load capacities, but are generally safe for their intended use. Choose a hoist that can move the heaviest items you usually work with, with some leeway for caution and efficient operation. 
•  Lift height - this is the distance between the ground and the hook suspending the load and determines the length of the lifting medium (wire rope, chain, cable) and overall purchase price considering all other factors are equal. It also allows more flexibility when working in varied settings or with loads of different sizes. 
•  Power source - does an electric work for your needs? Or do hazardous worksite conditions mean you need a pneumatic hoist? Choose the power source that works best for your needs if key considerations like load capacities are the same. 
•  Lift speed - does speed affect efficiency and productivity? If so, choose a hoist with variable lifting and lowering speeds. 
•  Maintenance needs - hydraulic and air hoists need fewer repairs and offer all-day operation with no downtime. Electric types, on the other hand, incur higher running and repair costs from common issues like overheating. 
•  Ease of use - for fewer safety risks and accidents, improved flexibility when lifting varied items, and consistent operation, choose a hoist that is also easy to use. Powered types cut out the strain of lifting heavy objects. But here too lifting controls need to be accessible, legible, and easy to use. For demanding operations like mining or construction, also consider features like longer pendant cables.
