Platform lifting is carried out by the hydraulic unit which acts upon the primary cylinders.
Lowering, even though electrically controlled, is carried out by the weight of both the platforms
and the load lifted.
The hydraulic system is protected by a maximum pressure control valve thus preventing pressure
from exceeding the maximum fixed safety limit.
The lifting and lowering motion of the lift is controlled by the buttons on the control desk panel.
Whenever the lift has to be lowered to the ground and the DOWN button is pressed, the lift will
stop at about 400 mm from the ground.
In this way, the operator must verify that neither persons nor objects are within the safety area.
In this case, the FINAL LOWERING button can be pressed and the lift be lowered.
A beep sound is heard during the last travel.
Note: auxiliary lift on models “AT” e “LTAT”, has similar functioning to main lift, except
lowering up to safety height (130 mm) which is electrically controlled.
