How to Determine the Ordering Specs for a Crane Hoist

An overhead crane hoist is a type of heavy equipment that’s used to lift and transfer heavy loads. They’re used in most industries, from agriculture and shipbuilding to mining and rail. 

A hoist and crane can cost anywhere from a few thousand dollars to a few hundred thousand dollars. Either price can be a huge business investment.

That’s why it’s crucial to know what to look for as you’re shopping around. Keep reading to learn how to calculate the ordering specs you need.

Lift Capacity

Every hoist will come with a capacity limit, which is the maximum amount of weight the hoist can handle.

To calculate the lift capacity you need, take a look at your business stats. How much does a typical load weigh at your company?

You should choose a hoist that will lift at 50% capacity. In other words, the hoist capacity should be twice the weight of the average load. This will ensure the safety and longevity of the hoist.

Lift Distance

The lift distance is the space between the hoist and the lowest area it needs to reach. The distance will determine how much vertical space the hoist can use.

To calculate this, measure the distance between the support beam and the floor. Then, subtract the height of the crane bridge. 

The lift distance will help the crane manufacturer decide what size you need.

Lift Speed

The lift speed is how fast the hoist will be able to pull loads up and release them down. Just like with vehicles or other heavy equipment, hoist motors are measured in horsepower. A horsepower is a measurement of pulling power, distance, and time. 

The higher the horsepower a motor has, the more expensive it will be. So, when calculating the lift speed, you need to consider the needs of your business.

If your operation needs to move heavy materials quickly, you will probably need a large motor. But if you infrequently move light materials, you could get by with a smaller motor.

Power Supply/Voltage

Hoists need electricity to pull loads. They can come in voltages of 115V, 230V, or 460V.

When shopping around for a hoist, it’s essential to know what your current electrical system can handle. You may need to call an electrician or refer to the building plans.

Choosing a crane system that is compatible with the electrical system you already have can save you a lot of money.

Crane Span

If you are installing the overhead crane at an indoor facility, you have to make sure it will fit. The span of a crane is a measurement of the distance between the runways.

If you’re ordering a new crane, measure the distance between the support beams where you plan to install the crane.
