Safety Trained Supervisor (STS) Practice Exam

Question: 1 / 400

What factor does NOT affect the load capacity of a mobile crane?

Operator training

Load weight

Installation of anti-two blocking device

The installation of an anti-two blocking device does not directly affect the load capacity of a mobile crane in the same way that the other options do. Load capacity refers to the maximum weight that a crane can safely lift, which is influenced primarily by factors such as the weight of the load, the training and skill level of the operator, and the positioning of outriggers, which can stabilize the crane and enhance its lifting capabilities.

The anti-two blocking device is a safety feature designed to prevent the crane's hook from inadvertently coming into contact with the boom, which can lead to dangerous situations. While it is essential for safe operations and preventing equipment damage, it does not alter the inherent structural or mechanical limits on how much weight the crane can safely lift. Thus, it is not a factor in determining the load capacity itself.
