OPJ vs. OPH , Choosing the Right Jackshaft
Both the OPJ and OPH are heavy-duty jackshaft operators from the Manaras Opera line. The OPH includes the Hoist-a-Matic feature , a manual chain that lets the door be lifted by hand while the operator remains powered. The OPJ omits this feature, making it the more cost-effective choice for facilities where manual operation under power is not required , sites with separate power-outage protocols or doors that are always operated electrically.
Typical Applications in Metro Vancouver
The OPJ's broad voltage range , including 600 V three-phase , suits older industrial buildings in Burnaby, Surrey, and Delta that run non-standard electrical service without a transformer. The 1 HP option handles doors at the maximum 24 × 24 ft size that exceed the capacity of a standard ½ HP jackshaft. Distribution centres and high-traffic loading docks benefit from the wall-mount configuration: no trolley rail overhead means no conflict with high-bay racking, sprinkler drops, or exhaust systems.
Common Failures & How We Repair Them
- Control boards: Power surges or moisture can damage the logic board. We stock replacement boards at our Richmond location for same-day or next-day swap.
- Capacitors: Single-phase motors rely on start/run capacitors that degrade over time. We carry the correct ratings for each voltage configuration.
- Limit switches: Mechanical wear or misadjustment causes over-travel or failure to close. We adjust or replace the switch assembly on site.
- Drive components: Sprockets, chains, and output shafts see heavy wear on high-cycle doors. We replace worn driveline parts with factory Manaras components.
Because Manaras manufactures in Montreal, Canadian parts distribution keeps lead times short compared to imported operators. Most OPJ service calls are completed same-day or next-day.
Parts & Accessories We Stock
Our Richmond shop keeps OPJ control boards, capacitors, limit switches, and drive components on the shelf. We also supply compatible photo-eyes, edge sensors, and commercial remotes. Pricing is quoted per project based on the specific motor voltage, horsepower, and accessory package required.
