Where the OSH Is Used
The OSH is built for the largest commercial and industrial rolling doors where uncontrolled coasting is unacceptable. The solenoid brake clamps the motor shaft the moment power cuts, delivering the precise positional stop required by fire-door regulations and preventing back-drive on heavy, unbalanced door assemblies. It is the go-to choice for high-cycle, high-speed doors in warehouses, loading docks and fire-rated openings throughout the Lower Mainland.
Common Failure Modes & How We Repair Them
- Solenoid brake wear or coil failure: The brake disc and coil degrade under high-cycle fire-door service. We replace the brake module, re-shim the air gap, and verify drop-test compliance on site.
- Motor thermal overload on 3Ø supply: Phase imbalance or undersized conductors trip the overload. We diagnose the supply, correct wiring, and swap the motor if windings are damaged.
- Limit-switch drift after emergency stops: Hard stops from the solenoid can shift mechanical limits. We recalibrate limits and test the full open/close cycle under load.
- Gearbox noise from shock loading: Instant braking transmits shock into the reduction gears. We inspect for worn gears or bearings, replace as needed, and confirm proper lubrication.
Choosing the Right OSH Variant
Selection hinges on door weight, cycle count, and the fire-door authority’s drop-test requirements. A 1 HP unit suits standard industrial rolling doors; the 2 HP version handles heavier assemblies and higher cycle rates. Voltage must match the building’s three-phase service (208 V, 480 V, or 600 V are common locally). We assess the door, confirm the fire-code schedule, and quote the correct HP and voltage configuration per project.
