3. LXL Operator Models And Features

3.1 General Description

B&B ARMR's model LXL hydraulic sliding gate operator is designed to reliably operate many
styles of sliding gates, including overhead track, ground track, and cantilever style gates. Our
LXL series of operators are designed to operate in all four UL-325 classes of operators. The
operator is unobtrusive in appearance, yet durable under heavy use. The design of the LXL
Series incorporates numerous features intended to improve safety, maintain security, increase
reliability and reduce maintenance.
The operator actuates the gate by two rotating wheels (the LXLR uses an idler wheel and pinion
gear). A drive rail bolted to the gate is drawn between the two drive wheels. The wheels are
spring loaded against the drive rail to produce a positive friction feed in both directions. Spring
loading the wheels also serves to correct for wheel wear. The drive wheels are rotated by series-
connected hydraulic motors to minimize uneven rotation between the wheels.
Rotation direction is determined by the hydraulic valve system, not by the rotational direction of
the electric motor. Independence from the electric motor rotation has the advantage that the
direction of gate travel can be instantly reversed without the use of brakes. Also, the hydraulic
valve, when not energized, rests in the neutral position. This effectively locks the hydraulic
system, drive wheels, and the gate in the stopped position. Controls operate on safe and reliable
24VDC regulated voltage.
