If you are looking for information or advice on hoists, our comprehensive guide can assist you. It covers the different types of hoists, their uses, factors to consider, and features to look for.
What are Hoists?
A hoist is a device that lifts and holds objects by using mechanical advantage. It uses pulleys or gears to change low force over long distances into high force over short distances. It has a chain or rope that wraps around a drum or wheel and then around other pulleys or gears with different sizes, some of which may be in the load block. The arrangement, affecting how the load’s force is shared or moved, is called the reeving. Hoists, whether fixed or mobile, can lift things for general or specific purposes, such as extracting a car engine. Hoists usually have a hook at the fixed end that attaches to a crane or trolley and a hook at the moveable end that grabs the load.

Applications and Industries
Hoists are versatile devices that can lift and move loads in various settings, not only in industrial ones. Hoists can handle different types of loads, such as cargo, construction materials, engines, and warehouse stock.
Some of the industries that use hoists are:
- Aerospace
- Automotive
- Construction
- Logging
- Marine
- Manufacturing
- Medical
- Mining
Considerations
Operating time, frequency of usage, and load all factor into the life of the hoist. These factors as well as travel distance and speed will also affect the lifetime of the trolley, where applicable. Using equipment above recommended parameters will lower the product lifetime.
Operating time
Frequency of usage, and load. These factors affect the durability and performance of the hoist and the trolley (if applicable). To extend the product lifetime, you should follow the manufacturer’s recommendations and avoid overloading or overusing the hoist.
Operator’s effort
Manual hoists (lever or hand-operated) require physical effort from the operator to lift or lower the load. You should choose a manual hoist that is easy and comfortable to operate and does not exceed the operator’s limits.
Structure’s capacity
The hoist should be compatible with the structure that will support it, such as a beam, rail, or crane. You should check the weight capacity of the structure and make sure that the hoist and the load do not exceed it.
Application’s requirements
Depending on the type and frequency of lifting you need, you may prefer a motorized or a manual trolley. A motorized trolley can move the hoist and the load along the structure faster and more accurately than a manual trolley. A motorized trolley is recommended for applications that require regular lifting of 2 tons or more.
Load’s characteristics
The load’s weight, size, shape, and material may affect the type of hoist and accessories you need. For example, some loads may require a special load block or hook to secure them. You should consider the load’s characteristics when assessing your lifting needs and choosing the right hoist and accessories.
Hoist’s features
Some hoists may have special or custom features that suit your specific needs. For example, some hoists may be explosion-proof, corrosion-resistant, or low-noise. You should consult with the manufacturer or supplier to find out what hoist features are available and how they can benefit you.
New vs. Used Hoists
- Inspect the hoist rigging equipment. Look for any signs of wear and tear, such as cracks, rust, corrosion, or deformation. Replace any damaged or worn-out parts as soon as possible.
- Perform regular maintenance on the hoist. Follow the manufacturer’s instructions and schedule for cleaning, lubricating, and adjusting the hoist. This will help extend the hoist’s lifespan and prevent breakdowns.
- Obtain the serial number of the used hoist. This will help you find out the hoist’s specifications and limitations, such as its lifting capacity, speed, and height. You can also use the serial number to contact the manufacturer or supplier for any questions or issues.
- Be aware of the safety regulations for overhead cranes.
Important Attributes
Lift capacity
This is the maximum weight that the hoist can support. It depends on the strength of the chain or rope, the frequency of use, the power source, and the structure that supports the hoist. You should choose a hoist that has a higher lift capacity than your heaviest load.
Line material
This is the material that the chain or rope is made of. The most common line materials are chain and wire rope or cable. They are suitable for lifting heavy loads. For lighter loads, you can use rope and strap or webbing. They are more flexible and easy to handle.
Power source
This is the source of energy that drives the hoist. The simplest hoists are manual, operated by hand chains or levers. They are cheap and portable, but require physical effort. Electric hoists are the most common, powered by electricity. They are fast and reliable, but need a power supply. Portable hoists can be powered by fuel, such as gasoline or diesel. They are convenient and versatile, but noisy and polluting. Air and hydraulic hoists are powered by compressed air or fluid. They are safe and durable, but expensive and complex.
Suspension type
This is the way the hoist is attached to the structure. Some hoists are fixed, hooked or bolted to permanent fixtures or movable stands. They are stable and secure, but limited in range. Some hoists are movable, attached to overhead trolleys. They can be pushed or pulled along a rail or have a motorized unit. They are flexible and efficient, but need a track or beam.
Lift height
This is the distance between the highest and lowest positions of the load hook. The higher the lift height, the more space the hoist needs. The lift height and the headroom are the two components of the reach, which is the total height that the hoist can cover.
Lift speed
This is the speed at which the hoist can lift or lower the load. The faster the lift speed, the more productive the hoist is. The lift speed can vary depending on the load weight and height. Higher capacity hoists usually have lower lift speeds. Some hoists have multiple or variable speeds, which can adapt to different loads and situations.
Headroom
This is the distance between the rail or tread where the hoist sits and the load hook. The lower the headroom, the more compact the hoist is. The headroom and the lift height are the two components of the reach, which is the total height that the hoist can cover. Before choosing a hoist, you should know how and where you will use it. You should make sure that the hoist can operate without any obstacles or interferences.
