LiftMaster MAXUM TDC. Standard duty: 85,000 cycles. Extended duty: 130,000 cycles. Contact DOORTEC for current warranty and motor sizing details.

The LiftMaster MAXUM TDC is the next-generation DC trolley commercial operator — purpose-built for high-demand standard-lift sectional door applications where faster operation, built-in facility monitoring, and maximum uptime are operational priorities.

Purpose-built DC motor and gearbox engineered for high-demand commercial applications — not a residential motor adapted for commercial use, but a drive system designed from the ground up to handle commercial duty cycles

Operates up to 33% faster than standard commercial door operators at an average of 12 inches per second for sectional doors and 8–9 inches per second for rolling steel doors — reducing cycle time and improving facility throughput

Built-in Wi-Fi connects to myQ® Facility software out of the box — no additional hardware required to access real-time door status, remote operation, and usage analytics from a mobile device

Floor-level 3-button wall control with 4-line LCD display for intuitive setup, programming, and maintenance tracking without ladders or specialized tools

myQ® Facility diagnostics let facility managers see door status, anticipate maintenance cycles, and identify issues before they become unplanned downtime — accessible via mobile device from anywhere

Soft-start and soft-stop operation extends operator lifespan by reducing mechanical stress on both the operator and the door during high-frequency cycles

Optional battery backup accessory (DC45AH or DC7AH) keeps the door operating through power outages — critical for facilities where door access cannot be interrupted

Security+ 2.0® radio technology virtually eliminates interference from competing radio signals and provides extended transmission range for reliable remote operation

Single modular unit handles both right-side and left-side mounting — dual handing capability eliminates the need to specify handedness at time of order

3 monitored safety inputs for entrapment protection devices — supports photo eyes, sensing edges, and other safety accessories required by UL 325

CPS-U Commercial Photo Eyes included in the box — entrapment protection is built into the package rather than requiring a separate accessory purchase

Works with myQ, myQ Facility, and myQ Enterprise — scalable from a single-door installation to a multi-site facility management deployment

Power options: 120V/240V single-phase or three-phase; 480V three-phase; 208V and 600V three-phase available with optional transformer accessory

Ceiling trolley mount designed for standard-lift sectional overhead doors — suspends from the ceiling and connects directly to the door drive, keeping the full opening width clear of obstruction

Trolley disconnect for emergency manual door operation — allows the door to be operated by hand when the operator is de-energized

DC motor and gearbox purpose-built for high commercial demands — the DC motor design provides stronger torque at lower speeds, smoother operation across the duty cycle, and longer motor life compared to standard AC commercial operators

12 inches per second average operating speed — up to 33% faster than standard commercial operators; in high-frequency warehouse and distribution applications this speed increase has a direct impact on throughput at every door cycle

Soft-start and soft-stop for extended operator lifespan — gradual acceleration and deceleration reduces mechanical stress on the operator, the door, and the door hardware on every cycle

Built-in Wi-Fi for myQ Facility software — embedded connectivity out of the box, no additional hardware required; connects to LiftMaster's cloud-based commercial facility management platform for remote monitoring and diagnostics

Floor-level 4-line LCD display — setup, programming, cycle count, and maintenance tracking are all accessible at floor level, eliminating the need to access the operator head for routine maintenance data

Battery backup standard — keeps the door operational during power outages; critical for loading dock and facility access doors where power interruptions cannot stop operations

Security+ 2.0 radio — virtually eliminates radio wave interference and provides extended transmission range compared to standard 315 MHz systems

Standard duty rated for 85,000 cycles; extended duty available for 130,000 cycles — documented cycle life ratings support long-term maintenance planning

The MAXUM TDC is the specification for standard-lift sectional door applications where maximum speed, built-in myQ Facility monitoring, and DC motor reliability make a measurable operational difference.

MAXUM TDC Installation in Oklahoma City

The LiftMaster MAXUM TDC is DOORTEC's specification for Oklahoma City facilities with high-demand standard-lift sectional door applications where the standard Elite Model T is sufficient in duty cycle but the MAXUM's additional speed, built-in Wi-Fi myQ Facility monitoring, and DC motor longevity provide a meaningful operational advantage. Distribution centers, food processing facilities, and any facility where door operators contribute to measurable throughput metrics are strong candidates for the MAXUM TDC. DOORTEC installs the MAXUM TDC throughout Oklahoma City, Edmond, Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and the OKC metro.

For OKC facilities evaluating the MAXUM TDC, DOORTEC's commercial team can walk through the ROI calculation — faster operation times at every cycle, reduced maintenance calls from soft-start/stop, and the operational insight from myQ Facility monitoring. Call (405) 720-7107 for a free commercial assessment.

MAXUM DC Operators Tulsa & OKC

DOORTEC's Tulsa location serves the greater Tulsa metro with the LiftMaster MAXUM DC line including the TDC. Tulsa's distribution and food processing sectors have strong demand for commercial operators that integrate with facility management systems — and the MAXUM TDC's built-in Wi-Fi myQ Facility connectivity meets that requirement out of the box.

For Tulsa and Oklahoma City facilities comparing the MAXUM TDC trolley against the MAXUM JDC jackshaft, the selection depends entirely on door lift type — TDC for standard-lift sectional doors, JDC for high-lift, vertical-lift, or rolling doors. Contact DOORTEC at (405) 720-7107 or doortec.com to discuss your specific configuration.
