LiftMaster JHDC MAXUM Vancouver
The LiftMaster JHDC MAXUM is the flagship heavy-duty jackshaft DC operator for commercial sectional and rolling steel doors. Custom Commercial Garage Doors Ltd supplies, installs, and services the JHDC MAXUM across Richmond, Vancouver, Burnaby, Surrey, Delta, and the Lower Mainland.
Overview
The JHDC mounts directly on the torsion shaft beside the door, keeping the ceiling clear for storage and lifts. The 24VDC motor delivers smooth soft-start and soft-stop on every cycle, protecting springs and hardware from shock loading. The MAXUM platform includes built-in battery backup capability and MyQ commercial connectivity out of the box.
Its hoist/chain disconnect allows manual operation during power failures — a code requirement in many BC commercial occupancies. The JHDC handles doors up to 40 ft wide and operates at 12 inches per second.
