Electric chain hoists are used for lifting and holding in suspension of various loads in rooms with a ceiling height of up to 12m. The equipment is compact in size with high power. This makes it indispensable for small industries like car repair shops, logistics centers and other enterprises.
Electric chain hoists come in different shapes and sizes, discussing what these are and what you need to look out for when choosing and buying. We have asked our helpdesk colleagues what they can tell about hoists: “The most important thing is that the maximum capacity of the hoist is being monitored.”
Types of electrical chain hoists
“The first thing you have to determine if the type of hoist that you need. For example, there are also electric or pneumatic hoists that do not require manpower. ”
Below are the differences:
A ratchet hoist with a lever: instead of a control chain, you use a control arm or lever to lift the load and lower it. Ratchet hoists are used for lifting loads at man height and are supplied with a standard hoisting height of 1.5 meters. Additional hoisting height can be ordered per meter. Ratchet hoists are available from 250 up to 6300 kg load.
A hand hoist: it is hung high, usually on a push-pull cat if you want to move the load horizontally. The load to be lifted depends on the so-called load chain. With the control chain, you manually raise or lower the load. Hand hoists are standard delivered with 3 meters of hoisting height, extra lifting height can be ordered per meter. Handbags are available from 250 to 10,000 kg of load. Electric telescope with hoist
An electric or pneumatic hoist: you can operate it with a control cable and does not require any manpower. These chain hoists are available with or without a push trolley or electric trolley. Electric hoists are standard delivered with 3 meters hoisting height, extra hoisting height can be ordered per meter. Electric hoists are available from 150 to 5000 kg. All electric chain hoists have a FEM group classification (see below).
Choosing the hoist
“The most important thing when choosing hoist is, of course, the maximum load, you can never hoist anything that is too heavy. Even if you only occasionally lift something heavier than the load capacity, it can go wrong. ” All electric chain hoists are fitted with a FEM classification. The FEM (European Federation of Materials Handling) has divided hoists into groups according to the average load and useful life. A hoist with a capacity of 500 kg that is taxed on average for 2.4 hours per day, for example, comes in FEM group 2m.
For hoists the following FEM groups are distinguished: – 1Bm (very light to light use) – 1Am (light to normal use) – 2M (normal use) – 3M (heavy use) – 4M (very heavy use) Furthermore, it is important that you look at the ‘useful height’ (the height of the hoist when the hoist is completely lowered) and the ‘minimum height’ (the height of the hoist when the hoist is fully raised).
And finally, the method of attachment is important, depending on the horizontal movement you want to make: Bar clamp Push trolley V2 Lifting bridge
- The beam clamp is used as a fixed point
- Free push trolley or hand mechanical trolley is manually used to move the load
- The electric trolley replaces the manual movement and is always supplied in combination with an electric chain hoist.
