Specification Features & Benefits
The operated variations of the barrier system use the latest technology for controls, including a custom speed control on the electro-hydraulic version. The electro-hydraulically operated system comes standard with built-in soft start and stop control. This advanced control technique allows for faster-operating speeds, yet reduces the mechanical wear from the shock associated with a sudden stop. The electro-hydraulic cabinet is self-contained and can be placed up to 30 feet from the arm.
The electro-mechanical TCRB-4 uses an electric motor, gearbox and chain assembly to operate the arm to the full up and down position. The electro-mechanical unit is self contained and is attached directly to the hinge stanchion.
