Self-erecting tower cranes run the risk of tipping much like mobile cranes.
In some cases, self-erecting tower cranes are replacing mobile cranes because of their efficiency in travel and set-up. Self-erector set-up is similar to mobile crane set-up. Both require firm, level ground with extended outriggers or stabilizers. Counterweights must be installed per the manufacturer’s specification like most modern mobile cranes.
Unlike traditional tower cranes, which experience structural failure if overloaded, self-erectors are more likely to tip over. However, like mobile cranes, self-erectors are difficult to turn over because of their large structural design factors and required load chart safety margins.
Our Tower Crane Operator & Inspector covers hammerhead, luffing, and self-erecting tower cranes.
