Amp draw measures how much power your machine consumes during operation. Horsepower is a unit of power that is the rate at which work is done. Here we are determining the amp draw of an electric chain hoist based on the horsepower of the motors. Knowing this value is important during the design or development stage of your purchasing process because it identifies if your circuit has enough ampacity to handle the additional load of the hoist.
The below chart breaks down the values based on single phase or three phase power which would be the power supply in your area as well as standard voltages.
You will need to know these two values to accurately determine the amp draw based on horsepower. An electric chain hoist uses a motor for the lifting operation. The spec sheet for the hoist will tell you the horsepower value for that hoist. If you are mounting the hoist to a motorized trolley, you will need to add the two horsepower values together (hoist and trolley) and then use the chart to determine the total amp draw.
Additional items will need to be taken into consideration as your system gets more complex. Loadhook can insure the electric chain hoist you’re seeking for your operations ensures maximum safety, efficiency, durability and economy. Contact us today!
