LiftMaster SL3000101UL Slide Gate Operator - 1 HP

Continuous-Duty Chain-Drive Automation for Heavy Commercial Slide Gates

The LiftMaster SL3000101UL is a 1 HP commercial slide gate operator designed for heavy, high-traffic vehicular entrances. Rated for gates up to 2,000 lb and 50 ft long, it combines a continuous-duty AC motor with a commercial oil-bath gearbox and #41 chain drive for residential communities, commercial properties, industrial facilities, and restricted-access sites.

The SL3000101UL moves the gate at approximately 12 inches per second and uses a 30:1 wormgear reduction for high-capacity operation. Mechanical limits maintain accurate open and close positions, while inherent obstruction sensing, monitored safety inputs, an included expansion board, Quick Close, Anti-Tailgate, and programmable auxiliary relays provide the control options needed for more complex commercial entrances.

LiftMaster myQ technology supports remote monitoring and gate control when paired with compatible LiftMaster connectivity equipment. The onboard Security+ 2.0 receiver supports encrypted tri-band wireless access, and the operator can communicate wirelessly with a second compatible operator for dual-slide gate installations.

Conclusion

The LiftMaster SL3000101UL is the higher-capacity 1 HP configuration in the SL3000UL family, intended for heavy slide gates and entrances that operate frequently throughout the day. Its continuous-duty drivetrain, 2,000 lb capacity, myQ compatibility, monitored safety inputs, included expansion board, photoeye, and edge sensor make it suitable for demanding commercial and perimeter-access applications.

LiftMaster requires monitored external entrapment protection in both the open and close directions. The included LMRRUL photoeye and S505AL monitored edge provide safety components for the installation, but the gate layout must still be evaluated to determine proper placement and whether additional monitored devices are required.
