What Can Mobile Cranes Lift

Action Crane Service

How much does a mobile crane lift?

A mobile crane’s lifting capacity is influenced by a number of variables, including the crane’s configuration, the boom’s length, weight, angle, and the load’s proximity to the crane’s centre.
According to its size and characteristics, a mobile crane can often lift anything from a few hundred pounds to several hundred tonnes. The mobile cranes in the Action Crane fleet have a lifting capacity ranging from a 36-tonne maximum for smaller jobs to up to 90 tonnes for larger projects.
It’s necessary for the mobile crane operator to follow the crane’s load chart to ensure safe lifting operations. A crane’s lifting capacity may not be its maximum load capacity because of several factors. The crane operator can calculate the maximum weight they can safely lift by consulting the load chart specific to that crane, which gives them details on the crane’s lifting capacity for various boom lengths, boom angles, and boom radii.

Crane Boom Lengths, Boom Angles, and Swing Radii Affect Lift Capacity

Different boom lengths, boom angles, and swing radii can have a significant impact on a crane’s lifting capacity.

Boom Length

The longer the crane’s boom, the less weight it can lift. This is because with a longer boom, the weight of the load is dispersed across a broader area, limiting the crane’s lifting capacity. A shorter boom length, on the other hand, enables the crane to lift greater weight because the load is dispersed over a smaller surface.

Boom Angle

The angle of the boom also affects the crane’s lifting capacity. As the boom angle increases, the lifting capacity of the crane decreases. This is because the weight of the load creates a moment on the crane, which increases as the boom angle increases. The crane’s lifting capacity is highest when the boom is at its lowest angle.

Swing Radius

The swing radius is the distance between the center of the crane and the load being lifted. As the swing radius increases, the lifting capacity of the crane decreases. This is because the weight of the load creates a moment on the crane, which increases as the swing radius increases. The crane’s lifting capacity is highest when the load is directly below the center of the crane.

What does this mean when choosing the right crane to hire

This means that, if the crane is lifting a load that is 50 feet away from the center of the crane, the moment on the crane is greater than if the load were only 10 feet away. As the moment on the crane increases, the crane’s lifting capacity is reduced. The crane’s lifting capacity is highest when the load is directly below the center of the crane, where the moment on the crane is the smallest.

The boom length, boom angle, and swing radius are all critical factors that affect a crane’s lifting capacity. The crane’s load chart provides information on the crane’s lifting capacity for different operating conditions, allowing the crane operator to determine the maximum weight they can safely lift. The certified crane operator at Action Crane will constantly monitor these lift factors while operating the crane and safely adjust the capacity.
