The qualified person inspecting the crane is responsible for the type and scope of the test.

 

Overview: Inspecting the crane

Gebot Anleitung lesen

Observe the product manuals!

In addition to the points described here, all information in the section Scope of the inspection in the other supplied product manuals also applies.

 

The items to be checked in the following list represent a general overview regarding the scope of testing of ABUS cranes. Depending on the type, not all components will be present on the crane.

The decision as to whether the crane is in perfect condition may be made only by the person inspecting the crane. Any inadequacies, if found, must be eliminated. The examiner decides whether the crane has to be tested again afterward.

If locally applicable regulations specify further tests, these are likewise to be carried out.

 

 

General overview of the points to be inspected:

*   Check the general condition. The components of the crane installation may not be damaged or rusted, or exhibit any other dangerous material changes.

*   Check the condition of the supporting structure. It should not exhibit any damage.

*   Check that the crane has been correctly installed and connected. It must be installed and connected in accordance with this and other product manuals.

*   Check the hoist drive, trolley drive and crane travel drive. They must be functioning flawlessly. For the test for switching on, see the product manual “Operating the ABUS crane”.

*   Test the brakes on the hoist drives, trolley drives and crane travel drives. They must be functioning flawlessly. For the test for switching on, see the product manual “Operating the ABUS crane”.

*   Check the hoist limit switches (switching points for safety limit switches and emergency limit switches). The hoist must switch off at the appropriate switching points.

*   If available: Check the operating limit switches. The hoist must switch off at the appropriate switching points.

*   Check the travel limit switch. The crane travel drives and the trolley drives must switch off at the appropriate switching points.

*   Check screws. All screws must be tightened and secured. If they are not, tighten the screws with the appropriate tightening torque and secure them.

*   If available: Check warning devices. They must function as intended.

*   Check the overload protection (e.g. load indicator system LIS or friction clutch). It must function as intended.

*   Check all other safety devices on the crane. They must function as intended.

*   If available: Check the condition of the wind anchor. It must function as intended.

*   Check the signage. The required signs on the crane must be present and legible. Otherwise, replace the signs.

*   Check weld seams. They should not be cracked or broken.

*   Check the condition of the paintwork. It should not be scratched or peeling. Otherwise, remove peeling paint and touch up the paint coat.

*   Check the load hook. See Checking the load hook.

*   Check the hoist drive, trolley drive and crane travel drive for tightness. The drives should not exhibit any exterior cracks or traces of leaked lubricant.

*   Check the air gap and brake lining thickness of the brakes on the hoist drives, trolley drives and crane travel drives. The air gap width must match that specified in the corresponding product manual. The brake lining thickness must match that specified in the respective product manual. Otherwise, adjust the air gap and, if possible, change the brake rotor with brake lining or the fan blade with brake lining.

If the width of the air gap is still within the permitted range but the wear behaviour indicates the air gap will be wider than permitted before the next inspection: The brake must now be adjusted accordingly or the exchange of the brake rotor with brake lining or fan blade with brake lining must be done now.

*   If necessary: Check the load capacity.

Check the load capacity using a test load approaching the maximum load capacity of the crane.

*   Check the lubrication of all moving parts. See Lubricants.

*   If applicable: Inspect conductor system. See Inspecting the conductor system.

 

 

Only with wire rope hoists

 

*   Inspect the wire rope. See Inspecting the wire rope.

*   Check the wire rope (on the cable drum and on the fixed point crosshead) and check the cable guide. The components should not be damaged, heavily worn, broken or loose.

*   Check the wheel flange wear of the wheels on the wire rope hoist.

*   Check the braking distance of the trolley drive.

*   Check the diameter of the guide rollers on the wire rope hoist.

*   Check the wheel diameters on the wire rope hoist.

*   Check the condition of the safety buffer on the wire rope hoist.

*   Check the condition of the bottom block (visual inspection).

*   Check the edge protection on the bottom block (visual inspection).

*   Check the rope wedge protrusion.

 

 

Only with chain hoists

 

*   Inspect the chain. See Inspecting the chain.

*   Check additional components. See the product manual for the chain hoist.

 

 

Only with cranes for operation in unprotected environments

 

*   Check rain hoods and similar covers for secure fit.

*   Check panels and connector housings. No water should have penetrated and the housings must be sealed.

*   Check the electrical system. Contacts and cables should not exhibit any areas of corrosion.

*   Check the lubricant in the bearings. The bearings should not be eroded or exhibit corrosion.

 

 

 

*   Check the test log book. See Checking the test log book.

*   Determine the already elapsed portion of the theoretical service life. See Checking the remaining service life.

*   Only if necessary: Perform additional country-specific tests.

*   Document the test. See Documenting the test.

Also in countries which do not require a test log book, it is recommended to document the test in the test log book.
