Pipe/hose rupture safety device
An electrically controlled valve is fitted on the lift cylinder. It is only possible to lower the platform with
a control signal from the control box, even in the event of a line/hose rupture.
The maximum descent speed is limited by an orifice (constriction) in the cylinder.
Battery charge protection
The charge protection prevents use of the machine during battery charging.
The charge protection switches off all machine functions during battery charging.
The LEDs on the control box flash sequentially to indicate this.
