"Green" Barriers

Delta Scientific of Palmdale, California, now offers more than 50 hydraulic barriers, barricades, bollards, and crash gates that can be run manually or on FDA-approved vegetable oils. The units typically remain in the upright position to protect the facility from trespas­sers and errant drivers. To let authorized vehicle through, the barriers are lowered. The hydraulic systems use a pat­ented low-duty cycle design that reduces the motor size by threefold or more. The manually operated products offer zero carbon footprint, simplicity, low maintenance, and quiet operation.
