INSPECTION OF ASSEMBLY
Test loading has been done in the factory and its information is registered on the log
sheet.
Equipment:
•
Check that all the pins, locking pins and other parts important for safety are secured
and that the threaded joints are tight.
Operation of the control valve:
•
Check that the control valve operation matches the diagram and the control levers
return to centre position (except for the extreme 'float' position).
Operation of the safety relief valve:
•
By listening carefully, check that the relief valves are working.
•
A pressure test can be performed from the pressure hose quick connector. Maximum
allowed pressure settings are outlined in the specifications.
Hydraulic equipment:
•
Inspect the condition of the hoses and couplings and make sure that the hoses do
not rub or twist with each other.
Labels:
Check that the machine has:
•
a manufacturing label
•
load label/high voltage wire label
•
a control valve lever operation diagram
•
a danger area label
•
Lifting hook label
Stability:
•
Check that the loader/forestry trailer combination is stable enough against
overturning.
•
Stability must be determined by either calculating using the formula in the loader
manual or experimentally, according to standard SFS 4677.
Stability determination in practice:
•
A loader is considered safe if, during the test ,no more than one support point is off
the ground.
Testing requirements:
•
The vehicle is tilted 5 degrees in the direction of tipping. During the test the vehicle
is in normal operating condition without load.
Test:
•
The test is performed in the most unstable direction and reach using a 10%
overload. During the test all normal movements must be performed with extreme
caution.
