Quarterly check of the efficiency of the channel profile trolley wheels (fig. 98):
•
Check the wear of the rolling band of the wheels
•
Check the ball bearings. They need to be replaced if there is excessive noise or if they have
excessive friction, “tugging”, difficult and/or irregular rotation
Replace the wheels if:
•
The rolling diameter of the wheel has wear
of 5 mm
•
The rolling diameter of the guide roller has wear
of 2 mm
•
If even just one wheel needs to be replaced, to obtain the best operating
guarantee and duration it is advisable to replace all of the trolley wheels
Annual check of the efficiency of the trolley buffers: (fig. 99)
•
Check that the end stops are not deformed and that there are no signs of their anchoring to the
structures giving way and that the buffer is intact and correctly fixed in its mounting.
Replace the buffers if they have:
•
Signs of breakage or permanent deformation, cuts, abrasions or incisions
