Special attention must be paid to rollers, as they must carry the entire load on
the one hand and ensure easy movement of the lift and chassis on the other.
Track rollers must therefore be inspected for deformation and damage to the
running surface (chipping, flattening, etc.) and the wheel flange (chipping, burrs,
etc.). The needle bearings must also be checked for ease of movement and
smooth running by turning the rollers.
Damaged rollers and bearings can no longer perform their task reliably and
must be replaced.
Rollers and needle bearings must be replaced together to prevent premature
failure.

Movement parts

All moving parts on the pit jack and chassis must run smoothly. This includes
not only the above-mentioned rollers.
If necessary, lightly oil or grease the movement points. Dirt and corrosion can
impair movement and must be removed.
12.3.4

Lifting brake

The lift brake prevents unintentional movement of the lift in the chassis.
Apply the brake to check. The function is fulfilled when the two flanged rollers
on the brake axle of the lever are pressed against the running profile in such a
way that movement is prevented without the brake lever coming into contact
with the structure.
