Notes for tower crane overload test under 10% dynamic load

In order to ensure the safe operation of the tower crane, not only the overload test of 10% dynamic load of the tower crane should be carried out, but also the overload test of 25% static load should be carried out. The following are the matters needing attention during the overload test of 10% dynamic load of the tower crane

At the maximum range, lift 110% of the corresponding rated weight and do compound actions.

2. At the minimum range, lift 110% of the maximum lifting weight and do compound actions.

At any range, lift 110% of the corresponding rated lifting weight and do compound actions.

According to the combination of the calibrated tower height and arm length, each combination state should be 1.1 times of the maximum rated lifting weight of the corresponding range.

Lifting mechanism: at the lowest stable working speed and the maximum working speed in the whole process of lifting height for not less than 3 times the lifting weight of the rated 1.1 times. It is required to start in the process of lifting and descending, the braking is stable, and the lifting weight should not slip after it stops at a certain lifting height.

Slewing mechanism: at the lowest stable speed, the rated lifting weight of the crane shall be no less than 3 times within the operating area, and the crane shall turn left and right, starting and braking shall be stable in the slewing process.

Walking mechanism: rail crane, lifting 1.1 times of rated lifting weight, lifting from the ground 500m, walking distance of 40m, 3 times round trip. The brake should be stable.
