Industrial hoists

What is a hoist?

A hoist is a mechanical device used to lift or move heavy loads by applying tractive force. It usually consists of a pulley, a cable or chain, and a lifting mechanism. It is commonly used in the industrial sector, on overhead cranes, jib cranes, or monorails.

What are the types of hoists?

There are manual hoists, motorized hoists with electric motors, and sometimes pneumatic motors. Load lifting with a hoist can be done using a chain or a cable. For intensive or specific use, "open winch" type hoists will be used.

Why is it so important to choose the right hoist?

Choosing the right hoist is important because it constitutes the central element of a lifting device and will be the most used component. Speed, type, and duty class are some elements to check when acquiring a hoist. Selecting the right hoist ensures efficient lifting operations and minimal maintenance.

Frequently asked questions

Q : What is the difference between a chain hoist and a cable hoist?

     A : In reality, both types of hoists have their utility, and the choice depends on the needs of each application. Cable hoists are preferred for loads exceeding 5,000 kg and rapid lifting, such as frequent loading and unloading of a trailer. Chain hoists, on the other hand, are renowned for their durability, making them perfect for mechanical workshops, maintenance, and machinery assembly. This debate persists because comparisons are inevitable. To delve deeper into the subject, here is an excellent article. What are the differences between wire rope and chain hoists?

Q : How to choose between a single-phase hoist (120 VAC) and a three-phase hoist (575 VAC)?

     A : The 575 VAC hoist is designed for industrial operations, offering robustness and performance for frequent lifting, long distances, or precision. Conversely, the 120 VAC hoist, due to its configuration and limitations, is better suited for residential or occasional use. If a 575 VAC power supply is not available, it is possible to consult an electrician for the installation of a phase converter.

Q: What are the disadvantages of using an electric hoist in a paint booth?

     A: Using an electric hoist in a paint booth presents risks of auto-ignition. The necessary explosion-proof equipment is expensive, and even pneumatic hoists must be classified as spark-proof to prevent any risk of deflagration.

Q: What is the difference between a winch and a hoist?

     A: Both a hoist and a winch are used to handle loads, but their operation and usage differ.

2. Hoist: Designed for vertical lifting, it uses a system of pulleys and chains or cables to lift loads with precision.
3. Winch: Primarily intended for horizontal pulling, it winds a cable around a motorized or manual drum to pull or move loads. It is often found on vehicles, construction sites, and towing installations.

In summary, the hoist lifts, while the winch pulls.

Q : Can a hoist be used for a freight elevator?

     A: A hoist is a lifting device designed to lift loads vertically. In Canada, its installation and use are governed by the CSA B167 standard. It is intended for lifting suspended loads and should not be used to move a cabin or platform between different levels.

A freight elevator is a lifting and lowering mechanism with a cabin or platform that moves between two or more levels. Its installation must comply with CSA B44/ASME A17.1 standards, which impose strict safety requirements, including safety brakes, fall protection devices, and access-limiting safety systems. The installation of freight elevators must also meet the safety obligations applicable to elevators and be maintained by a qualified contractor with RBQ sub-category 14.1 Elevators and freight elevators.

In conclusion, a hoist and a freight elevator have distinct functions and designs. Using a hoist as a mechanism for a freight elevator does not comply with Canadian safety standards. For any freight elevator installation, it is essential to follow the CSA B44 standard and check the installation requirements with the RBQ.
