Industrial Hoists in Quebec | Premium Industrial Group

What is a hoist?

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

What are the different types of hoist?

There are manual hoists, motorized electric hoists and sometimes pneumatic hoists. Loads can be lifted using chain or wire rope. For intensive or specific use, custom-made"open winch" type hoists are used.

Frequently asked questions

01.

What is the difference between a chain hoist and a wire rope hoist?

A: In reality, both types of hoists have their uses, and the choice depends on the requirements of each application. Wire rope hoists are preferred for loads over 5,000 kg and fast lifting, such as for frequent loading and unloading of a trailer. Chain hoists, on the other hand, are known for their durability, making them ideal for mechanical workshops, maintenance, and machinery assembly. This debate persists because comparisons are inevitable. For more information on this topic, here is an excellent article: The differences between wire rope and chain hoists.

02.

How do you 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, over long distances or with 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, consult an electrician about installing a rotary phase converter.

03.

What are the cons of using an electric hoist in a paint room?

A: Using an electric hoist in a paint booth poses a risk of spontaneous combustion. The necessary explosion-proof equipment is expensive, and even pneumatic hoists must be classified as spark-proof to avoid any risk of explosion. For more details, see our article: Hoists for paint booths: what are the recommended solutions?

04.

What is the difference between a winch and a hoist?

A: A hoist and a winch are both used to handle loads, but they differ in how they work and how they are used.

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

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

05.

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 CSA B167. It is intended for lifting suspended loads and must not be used to move a cabin or platform between different landings.

A freight elevator is a lifting and lowering mechanism with a cabin or platform that moves between two or more landings. 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 comply with the safety requirements applicable to elevators and be maintained by a qualified RBQ contractor in subcategory 14.1 Elevators and Freight Elevators.

In conclusion, hoists and freight elevators have distinct functions and designs. Using a hoist as a freight elevator mechanism does not comply with Canadian safety standards. For all freight elevator and material lift installations, it is essential to follow CSA B44/ASME A17.1 and verify installation requirements with the RBQ.
