“I don’t see Columbus McKinnon hoists rated with horsepower, however, they are sometimes referred to by that rating. Does that relate to the FPM capability? I am guessing that a faster FPM hoist would have to have a ‘stronger’ electric motor. Looking forward to your comments.”
To answer this question, let’s take a look at the history of horsepower. When steam engines were invented, the designers wanted to know how much work the steam engines could do in comparison to a horse of that day. This is where the term horsepower originated.
Horsepower is a measurement of power at the rate at which work is done. When we measure the power of a horse, we see that one horse can do 33,000 foot-pounds of work per minute.
Now, the question of horsepower is: I want to move an object from one place to another in a specific amount of time. How much effort (or power) will this take?
Looking at the Lodestar, this hoist can have a variety of different horsepower ratings, depending on the capacities and speeds. For example, take a look at the 1/2-ton Lodestar below:
We also need to consider the gear ratio and the type or size stator we use in the motor to accomplish how much weight and at what speed the hoist needs to work.
