Crane Load Charts

Before doing any lifts activities, the crane lifting capacities against loads must be checked and satisfied all requirements listed on the load chart, range diagram and rated capacity chart to avoid the overloading. Particularly, when crane is adding with fixed jib, frame jib, telescopic jib, lattice jib, luffing jib, fly jib....the checking must be done carefully.

Note:
1. The rated lifting capacity shown in the chart is a combined maximum weight that are include:

The weight of the hook block

+

The weight of the lifting equipment

+

The weight of the load

+

Any other amount as specified by the manufacturer in the Condition of Use

2. The operating Radius:

Operating radius is the horizontal distance from a known point on the crane (usually the centreline of rotation) to the centre of gravity of the load.

3. Overloading of the crane can cause either overturning or structural damage or failure.
