Overload limit is set correctly. Running In All functions are to be operated without load, throughout their permitted range. If a hoist is fitted, the hoist drum should be rotated four times in each direction. Slew the loader crane fully, clockwise and anticlockwise. Calibration Check Test Weights The following test weights should be used. Weights of proven accuracy to within +/-1.0%. Weights proven on a weighbridge. The weighbridge must have been calibrated to within within the last 12 months. For weights suspended from a calibrated weighing device, the weighing device must have been calibrated to within +/-1.0% within the last 12 months. Check that the Rated Capacity Limiter operates to prevent dangerous movements and allows return movements to a safe condition. Remember that the test load shall be the combination of the test weight and any slings or chains. Dynamic Test The object of this test is to subject the structural members to dynamic conditions and fluctuating loads, in order to check functionality through its full range of travel. Dynamic tests should be performed separately for each loader crane motion. Testing shall be carried out at speeds to those appropriate for normal crane operation and shall include repeated starting and stopping of each motion throughout the range of the motion. However, aggressive shock loading should be avoided. The test load shall be 110% of the Rated Capacity for the maximum extension. All crane positions attainable in service should be reached during the course of the tests. The test shall be considered successful if all components have been found to perform their functions correctly in accordance with the design specification and if an examination after the test reveals no damage to the mechanisms or structural components. Overload Test Introduction The purpose of the overload test is to confirm the structural integrity of the lorry loader. This includes anchorages to the vehicle, vehicle structural parts and stabiliser legs.
