When lifting from the main boom, which crane feature is considered in weight calculations?

When lifting from the main boom, the effective weight of crane components past the lifting point is a critical factor in weight calculations. This is because any load that extends beyond the point where the crane is lifting adds to the overall effective weight that the crane must support. This includes not only the weight of the load itself but also the weight of the boom, rigging, and other components that contribute to the total lifting dynamics.

Understanding this concept is vital for ensuring safe lifting practices. If the effective weight is not accurately calculated, it can lead to overloading, causing potential failure of the crane, compromising safety, and jeopardizing the integrity of the lifting operation. Therefore, the effective weight of crane components past the lifting point must be considered to maintain the crane's stability and operational safety.

In contrast, elements such as crane color, type of load, or length of the boom do not directly influence the weight calculations in the same manner. The focus should always be on the total effective weight that impacts the lifting capability of the crane.
