LiftMaster MAXUM JHDC. Contact DOORTEC for current warranty terms and motor sizing details. Battery backup is an optional accessory.

The LiftMaster MAXUM JHDC brings MAXUM DC Series performance to rolling door and large commercial door applications requiring hoist-style operation — the highest-specification commercial operator in the LiftMaster MAXUM lineup.

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

Wall or hood mount jackshaft hoist configuration for rolling doors and larger commercial door applications — hoist-style emergency operation provides manual door control via chain at floor level, meeting requirements where floor-level emergency access is specified

Chain hoist emergency backup allows the door to be manually operated from floor level without power — the defining functional difference between the JHDC and the JDC, and the reason hoist configurations are specified in applications with floor-level emergency operation requirements

Suited for high-frequency rolling door applications including distribution centers, food processing facilities, and loading dock operations where the combination of DC speed, myQ Facility monitoring, and hoist emergency operation is the complete specification

DC motor and gearbox purpose-built for the highest commercial demands — the JHDC's DC motor provides the sustained torque output required for larger and heavier rolling door applications across a demanding duty cycle

12 inches per second average operating speed — up to 33% faster than standard commercial hoist operators; at high-frequency loading dock and distribution center doors, this speed improvement has a direct and measurable impact on facility throughput

Built-in Wi-Fi and myQ Facility connectivity out of the box — the JHDC connects to LiftMaster's commercial facility management platform for real-time status monitoring, cycle counting, and predictive maintenance alerts

Floor-level 4-line LCD control panel — all operator programming and maintenance data accessible at floor level, eliminating the need to access the operator head for routine checks on operators mounted high or in confined overhead spaces

Soft-start and soft-stop — reduces mechanical stress on the operator and the rolling door or grille curtain system on every cycle, a meaningful factor in extending component service life on high-frequency applications

Emergency hoist operation for manual door control during power outages or operator service — ensures the door can always be manually operated regardless of power or operator status

Optional battery backup accessory — for applications where continuous powered operation during outages is required, the battery backup ensures the JHDC keeps running; the option allows facilities to choose the right specification for their specific uptime requirements

The MAXUM JHDC is the top-specification commercial operator for rolling door and large commercial door applications where MAXUM DC speed, Wi-Fi myQ Facility monitoring, and DC motor reliability are all required.

MAXUM JHDC Installation in Oklahoma City

The LiftMaster MAXUM JHDC is DOORTEC's specification for Oklahoma City facilities with large rolling steel doors and high-demand commercial door applications where the full MAXUM DC Series performance suite is required in a hoist configuration. For distribution centers, loading dock facilities, and manufacturing plants running high-frequency rolling door cycles, the MAXUM JHDC's 12"/sec DC motor, built-in Wi-Fi myQ Facility connectivity, and soft-start/soft-stop represent a meaningful upgrade over the standard Elite Model H. DOORTEC installs the MAXUM JHDC throughout Oklahoma City, Edmond, Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and the OKC metro.

For Oklahoma City facilities evaluating whether the MAXUM JHDC or the optional battery backup is appropriate for their application, DOORTEC's commercial team can assess your power infrastructure and uptime requirements. The optional battery backup is recommended for loading dock doors and any rolling door application where a power outage would cause a significant operational disruption. Call (405) 720-7107 for a free commercial site assessment.

MAXUM DC Hoist Operators Tulsa & OKC

DOORTEC's Tulsa location serves the greater Tulsa metro with the LiftMaster MAXUM DC line including the JHDC. Tulsa's industrial and logistics infrastructure includes many facilities with large rolling doors and high-frequency duty cycles where the MAXUM JHDC's DC motor performance and built-in myQ Facility monitoring provide the best available commercial operator specification.

For Tulsa and Oklahoma City facilities comparing the MAXUM JHDC against the Elite Model H, the key differences are speed (12"/sec vs standard), built-in Wi-Fi and myQ Facility monitoring (MAXUM only), and soft-start/soft-stop (MAXUM only). Contact DOORTEC at (405) 720-7107 or doortec.com to discuss which specification is right for your facility.
