The Hoist is the part of the crane that does the actual lifting and lowering of loads. There are several different types available, which can be powered manually, by electricity or pneumatically. You will also find chains, wire ropes or fibres as an integral part of the Hoist.
The choice of material and power source for your Hoist has a major impact on the function of your crane. It will affect load capacity, precision of lifting and durability, so you need to ensure you choose the right lifting equipment for your needs.
What Types of Hoist Do You Offer?
We can source many types of Hoist for your crane, read the list below to understand the features of each:
Electric Chain Hoist Used wherever there is an electrical power supply and typically offering capacities from 125Kgs through to 5 tonnes. Chain hoists generally provide true vertical lift and are an ideal choice in situations where very precise lifting and placement is needed.
Electric Wire Rope Hoist Typically available in higher capacities than electric chain hoists, these range from 1 tonne to 100 tonnes. The electric wire rope hoist is often a permanent fixture in factories and is used at various stages of manufacture and loading.
Manual Chain Hoist A low cost option, but still capable of lifting capacities from 500kg to 10 tonnes. This Hoist is portable, lightweight and can be used where no power supply is available. This is often used by small engineering companies who only need to lift goods occasionally.
Ratchet Lever Hoist (pullift) Small, compact and easily transported in engineers vehicles for on site applications. The rachet lever hoist is usually used for low head room lifts, such as removing a car engine, or pulling pieces of work together for welding.
They often come in capacities from 500kg to 6 tonnes and usually give a height of lift of around 1.5 metres, but longer chain lengths are available to order.
Wire rope hoist (tirfor) lifting and pulling machines Lever operated wire rope hoists which can be used for lifting or pulling. They are usually supplied with a standard 20 metre rope, but because the wire rope passes through the machine, the rope length is effectively endless.
These are commonly used for recovering vehicles and to pull pipes and cables underground. The capacity does vary depending on the function – with a range from 800kg to 3.2 tonnes for lifting, but a greater capacity range from 800kg up to 5 tonnes for pulling.
Air Hoist Pneumatic hoists are used wherever a ready air supply is available. They are also used if there is a risk of explosion that means no electrics can be used on the site, for example in chemical plants and underground. Typical capacities for air hoists range from 125 kgs through to 6 tonnes.
