#1. Weight of Load
This is the first and most important factor you need to consider when buying an Electric Chain Hoist.Firstly, it is essential to determine the average load lifted and the maximum weight or 15%-20% more than the average and how often.
As a rule; for capacity 4 tons and less the chain hoists are the most preferred choice. But this does not hold with every industry.Depending on your industry needs and requirementsthe choice of hoists will vary.
#2. Lifting Speed
The next factor which needs to be considered is the speed of lifting motion, which must be carefully calibrated for loading and unloading of goods and can be safely accomplished
lf the correct Electric chain Hoist is selected it can beused up to 8-10 hours with 20-30 lifts per hour.
#3.The Height of lift
The next factor which you need to consider is the height you need to lift the load.Most electric hoists include a chain container; the height of lift controls the size of the chain container required.
The distance from the mounting of the hoist to bottom or saddle of the hook when the bottom hook is at its uppermost position needs to be taken into consideration. You will need to ensure you have enough height for your application.
#4. The Power source
The application of hoist will also determine the type of power source you need to use.First you must determine the duty cycle Low-Duty cycle or Heavy-Duty cycle which is typically defined by the number of lifts per hour.
When a Heavy-Duty cycle exists a higher voltage is desired
Some of the Electric chain hoist is manufactured to operate on either 120V/208V or 230V1 460V for single phase power and will not be enough if you are using it for a Heavy-duty cycle.
It is always better to predetermine the availability of power supply before buying an electric chain hoist
