Contents
Limiting overtravel of lifting carriages
Applicability
VLE 2130, VLE 2130 F
Each column of the lifting platform is provided with a
control mechanism with adjustable friction effect. This
makes it possible to limit the overtravel of the lifting
carriages caused by mass inertia.

1 Slider
2 Pressure spring
3 Bolt and nut
¶
Adjust the pre-tension of the pressure spring
(Fig. 13, Pos. 2) with the nut (Fig. 13, Pos. 3).
i
Without load, it must still just be possible to turn the
large V-belt pulley with both hands.

Adjust the pre-tension of the friction lining (Fig. 14,
Pos. 1) by way of the hexagon bolt (Fig. 14, Pos. 4).
i
It must be possible to turn the spindle at the large
ribbed belt pulley by applying a force of approx.
10–12 Nm
(with support arms in position). With the
cover removed and no load being applied, it must
still just be possible to turn the large ribbed belt
pulley by hand.
