At JASO Industrial Cranes we have designed a formula with which you can choose the hoist that best suits your project’s needs

Our expert technical team explains in a simple way how to use this formula to get the best from our hoists.

The first thing to do is the following mathematical operation, which will give you the hoist’s daily usage time.

For this you need to know information such as the average lifting height, work cycles per hour, operational time per day and lifting speed.

In order to fully understand the formula, we give the following example. Let’s suppose we have the following data:

• Average lifting height: 6 m
• Work cycles per hour: 25
• Operational time per day: 8 h
• Lifting speed: 5 mpm Therefore, we now know that the daily usage of the hoist will be 8 hours.

Once the first step is completed, we move to the following table. To do this, we need other data such as the type of load, the load to be lifted and the arrangement of the cable.

Continuing with the example, let's assume we need a hoist with the following characteristics:

• Daily usage: 8 h (data obtained from the previous formula)
