GENERAL ADVICE

According to the Swedish Work Environment Authority’s regulation AFS 2006:6 §30, daily inspections shall be made in accordance with manufacturer’s instructions. The manufacturer states the things that shall be maintained and inspected and the interval at which this shall be done. Shortcomings or damage discovered during inspection shall be reported to the person responsible for the crane prior to continued use. Brief general advice for daily inspection. This advice is not intended for any specific crane.

1 Inspection of the cable.

4 Inspection of control unit.

.1 1 1.2

4.1 4.2 4.3

Inspection of the cable, damage, broken wire and damaged strands. Check the cable every day, the cable is a wear part that is easily damaged. Check that the cable does not have any kinks or compression damage. There should not be any broken wires. Visible broken wires are often an indication of a larger number of invisible breaks. Check that the cable is correctly located in the pulley wheels / drum. Check from floor level that the visible part of the cable is correctly located in the pulley wheels’ tracks, at the hoist machinery as well as the hook block. If the cable is off-line or loose, it can hop off the pulley wheels and could be damaged. For this reason, pay attention to changes in cable angle.

2 Inspection of pulley block 2.1 2.2

Check that the hook will be able to move easily in all directions. It shall be possible to rock the hook with its hook head in its attachment and rotate it. Sluggishness in the bearings may result in hook fracture. Check the safety catch and its function. The hook catch prevents unintentional loss of hook function in connection with loose line or load settling. According to the AFS 2006:6 instructions, there shall be a hook catch.

3 Inspection of lift limit switch. 3.1 Check that the upper limit position is working correctly. Run up carefully and check that the lifting movement stops at the normal upper level. If the upper limit position is not working, it may result in the hook block being run up into the machinery, which will result in extensive damage and it is a serious safety risk. 3.2 Check that the lower limit position is working correctly. Run down carefully and check that the lifting movement stops at the normal lower level. If the lower limit position is not working, it may result in the line winding on the cable drum backwards.



Check that the control unit is not damaged. If there is visible damage, there is a risk for other damage, this may be due to damp or dirt penetrating the cover and it could cause dangerous malfunctions. Check that the buttons are not loose or damaged. Damaged buttons may stick in the active position, which could result in dangerous operating situations. Check that the buttons match the intended function and speed. If there is a fault in the function and speed, it may be because of a serious fault in the control system.

5 Inspection of brakes. 5.1 5.2

Check that the sound from the brake sounds as normal on start and stop. Check that the lift stops with a normal stopping distance on normal stop. Changes may be due to wear in the brake lining or because the brake does not release even though the crane is running. Do not test the brake by stopping a lifting movement with the emergency stop. Emergency stop shall only be used in emergencies and after the work is finished.

6 Emergency stop button 6.1 Inspection of emergency stop button. Check that the button works correctly in purely mechanical terms and that it remains activated and that the reset function works. 6.2 Check, with the emergency stop button depressed, that it is not possible to run any movement. Test the operating buttons for all movements. According to the instructions, an emergency stop button shall stop the operation in another way than the ordinary one. If a movement freezes, it is thus important that the emergency stop is tested and functions.
