What should crane operators know about mobile crane lifting capacity?
Mobile crane lifting capacity decreases with boom length, radius, and angle. Always consult load charts and account for dynamic forces, ground conditions, and weather.
Mobile crane lifting capacity is determined by multiple interconnected factors that operators must understand thoroughly. The primary variables are boom length, load radius (horizontal distance from the crane's centerline to the load), and boom angle. As any of these increase, lifting capacity decreases significantly. Load charts provide specific capacities for each configuration and must be consulted before every lift.
Remember: "BRAG" - Boom length, Radius, Angle, Ground conditions all reduce capacity
