Select The Right Electric Chain Hoist Can Be Confusing

By:


Electric chain hoists are used most often which we dont notice, but this is the most helpful machinery helping us in daily

tasks. Therefore, it is essential to be careful before buying for yourself. Selecting the right electric chain hoist

sometimes becomes confusing, but if following these easy and effective tips will help you going in the right direction.

1. How effective are the Motors Mostly, hoist motors run at the minute rate (motors will run on an alternative 30 minutes

duration). It is required for a hoist to run for 30 minutes (not more than that) to have an even time of running and resting

not to exceed 30 minutes. If the machine has high duty cycle, it may run for 60 minutes or continuous duty motors.

2. How much capacity of the hoist is required - Hoists are designed for a 1 to 5 safety factor mechanically. This means that

hoists cannot take the load throughout the day. For example a 10 ton hoist operated at a mean effective load of 5 tons will

have a bearing life 8 times that of the hoist run at its rated capacity. Therefore, you need to be careful about the load

before buying chain hoist.

3. Hoist and suspension - There are a different ways through which an electric chain hoist can be provided with suspensions.

These are of three types a) Top hook, b) plain push trolley, and c) hand geared trolley or motorized trolley. For light

capacity and light duty hand push can be desirable. A geared trolley is used when you do not need to move the hoist very far,

and motorized trolley is best suitable when you have to move the trolley very far, very often.

4. How much lift do you need - Electric chain hoists can be used for longer lifts but it is important to consider the number

of chain drops. You can end up with a very large chain container and heavy hoist if there is too much chain. Electric wire

rope hoists are typically used for long lifts. Three ton and above with lifts exceeding 35' is a generic cut off point to go

from chain hoist to electric wire rope hoist. Remember you can deduct the headroom of your hoist from the lift required but

do not forget to account for any pits you may be going into to make you lift.

5. How much control on hoist and trolley is required - Even a single speed control may work for your job if it is not much

crucial, but if your product is expensive, then delicate placement may be requires so that two speed or even variable

frequency control on the hoist and trolley.

6. Special considerations - There are numerous types of limits which can include over travel, and control circuit which need

to be discussed in detail with your sales person. In most of the cases, electric chain hoists come with an upper and lower

limit switch which will limit your upper and lower travel. Few do not come with an over capacity limit as standard. It can

prevent damaging your supporting structure and the product you are lifting, especially if the product is held in place by

some type of fixture.
