If counterweight is reduced below the recommended level, what is the primary risk?

• A. Decreased stability and capacity, potentially making lifts unsafe
• B. Increased stability
• C. No effect
• D. Increased lifting speed

Answer: (A)

Counterweight helps balance the crane by offsetting the weight of the load and the boom, creating a stable base. If you reduce the counterweight below what the manufacturer specifies, the crane’s ability to resist tipping is reduced. The load charts used for safe lifting assume the recommended counterweight; with less weight, the same reach and load become unsafe because the moment from the load can overcome the crane’s stability. Wind and dynamic movements during lifting make tipping risk even greater. So, the primary risk is decreased stability and capacity, potentially making lifts unsafe. Increasing stability, having no effect, or increasing lift speed would not describe the consequence of reducing the counterweight.
