These devices can be attached directly to the rigging to give you an accurate measure. It is worth investing in a dynamometer to allow you to measure each load before each lift. You can also physically weigh an example load using an industrial scale. Manufacturers are an excellent source for this information for individual parts that you can then add together. These weights need to be as accurate as possible. Load calculations should take into account the weight of everything being lifted, including: While it can be relatively straightforward, at times, you will need to do some math and work with formulas in order to find the number your crane rental company will need.
Load calculation refers to the way in which you determine how much weight the crane will be lifting. This is especially relevant if you plan on performing a critical lift, a lift performed at 75% or more of the crane's capacity. You need to know several things about calculating a load's weight before you rent a crane.
When it comes to jobs that require cranes, one of the questions your crane rental company will ask is the total weight of the load. How heavy it is, and where you need to lift it from and to. The first step in understanding crane loads and determining what machine you need on site is to accurately determine exactly what you need to lift.
