Functional description
21.4.8 Fork lift
When the driver actuates the hydraulic control R11, a voltage of 3.7-
6.6
V is fed to the input on A5 and direction valve Y10 opens and sends
a signal to transistor regulator A2. The pump motor M3 starts and
pumps oil to the lifting cylinders.
If the battery monitor has detected 20% or lower battery capacity, lifting
speed will be reduced.
The lifting speed is reduced with the transition from free lift to main lift.
The speed of M3 is measured by sensor U12.
21.4.9 Maximum height
Truck with maximum height switch.
When the forks reach the height switch S32 and A5 receives a signal,
the fork lift will be stopped. If the forks are to be lifted above this height,
switch S33 must be depressed, which sends a signal to A5 and move
-
ment continues. Start must occur within fifteen seconds.
