The qualified person inspecting the crane is responsible for the type and scope of the test.
|
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 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.
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.
Inspect the chain. See Inspecting the chain.
Check additional components. See
the product manual for the chain hoist.
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.
