Barriers and halfbarriers are providing additional safety for traffic participants by creating a physical obstacle for road vehicles when the level crossing protection system is switched on.
Technical highlights PB13
Barrier Drive PB13 uses a 24 V DC electric motor for rising and lowering the barrier arms. The electric motor is fitted with an electromagnetic brake which provides locking of the barrier in vertical, horizontal or current position.
The Barrier Drive door has three locks - two for mechanical latching to the frame and a key lock to prevent unauthorized door opening.
Barrier arm length up to 10,5 m.
In specific cases, there is also the possibility to manually operate the barrier drive, using a mechanical lever, in which case the electric motor and the brake are automatically switched-off.
Configurable arm lifting and lowering times and detection of broken barrier arm.
Built-in heater for the barrier drive.
Technical highlights PBH21
PBH21 is using completely hydraulic system for rising and lowering of barrier arms. Locking in end position is provided by means of electromagnetic valves. There is a possibility to lock the arm in any position with manual hydraulic valve. Automatic (controlled by central device) and manual (man controlled) operation is possible. Barrier is driven to the vertical and horizontal position by hydraulic cylinder. Up to 3 complete manipulations (rising and lowering) are ensured if power supply is cut off.
Low maintenance device. Periodical visual checks and at least 5 year interval for changing of hydraulic piping.
Automatic and service modes.
3 manipulations after a power supply cut off.
Rising of the barrier adjustable any requirement (market specific).
Adjustable lowering and rising times (from 5 seconds onwards).
