The combination of proven and reliable electric motor with a lever system represents a simple and extremely reliable drive solution. It permits short opening and closing times without the barrier boom bouncing in the end positions. The lever system locks the barrier boom at both end positions. In the event of a power failure, it can still be moved easily by hand.

The barrier boom is extruded from highly stable aluminium alloy to produce an octagonal
profile of 4“ x 2 1/8“ x 1/16“ and finished with an RAL 9010 white powder coat then applied with bright red reflective tape strips. Hence the boom is readily visible even at night.

The controller using microprocessor technology to ensure a flexible, modern approach to the control techniques, it possesses all appropriate expansion options including an I/O box and serial communciations interface. The MLC and ancillary control units arefitted on to the fold out mounting plate.

If the available vertical height is restricted, the barrier can, at extra cost, be supplied with an articulated boom. In order to calculate the dimensions of the articulated boom, the barrier length (D=) and height (H=) must be supplied.
