The LiftMaster HDSL24UL is a heavy-duty variable speed slide gate operator engineered for extreme high-cycle applications requiring maximum pulling force, continuous-duty reliability, and advanced smart access functionality. Designed for industrial facilities, distribution centers, commercial properties, secured campuses, transportation facilities, and large gated communities, the HDSL24UL combines high-performance gate operation with intelligent control and monitored safety protection for demanding perimeter security environments.
Powered by a custom 1.5 HP peak 24VDC brushless continuous-duty motor and heavy-duty size 70 direct-drive gearbox with 40:1 gear reduction, the HDSL24UL is capable of moving gates weighing up to 3,000 lbs. at speeds up to 1 ft. per second. Variable speed control allows adjustment from 0.5 ft./sec. to 1 ft./sec. to meet application-specific requirements, while smooth start/stop operation and mid-travel reversal help reduce mechanical wear and extend hardware life. The operator’s #40 industrial chain provides pull strength rated at twice the gate weight for reliable operation in extreme-duty environments.
Integrated myQ® connectivity provides full visibility and control over facility and community access points, allowing remote monitoring and management through Smart Community Access and Smart Facility Access platforms. Wireless dual-gate communication synchronizes dual-operator systems while eliminating costly trenching requirements, with independently adjustable gate speeds available when needed.
The HDSL24UL includes monitored entrapment protection devices and is UL® Listed for Class I, II, III, and IV applications. Quick Close and Anti-Tailgate functionality help minimize unauthorized access opportunities, while PosiLock® automatically secures the gate if forced from the closed position. Multiple programmable auxiliary relays allow expanded accessory integration for advanced site functionality.
