Answer:
The unit features a mechanical drive and twin-disk anti-crushing clutch fully immersed in an oil bath using FAAC HP OIL for continuous heat dissipation and wear reduction. It also incorporates a non-reversing reduction system that mechanically locks the gate when stopped, alongside a keyed manual release mechanism.
The FAAC 844 C Z16 operator is engineered specifically for intensive, high-traffic duty cycles. Its core construction and safety features include:
- Oil-Bath Lubrication: The electro-mechanical reduction transmission and twin-disk clutch are continuously immersed in FAAC HP OIL. This internal liquid bath optimizes thermal dissipation during high-frequency cycles and minimizes mechanical wear on moving gears.
- Adjustable Twin-Disk Clutch: Mechanical anti-crushing protection is provided by an oil-immersed twin-disk clutch calibrated via an internal adjustment screw to establish precise force thresholds before mechanical slippage occurs.
- Self-Locking Non-Reversing Drive: The worm-gear reduction system automatically locks the gate leaf in both closed and open positions when the motor is de-energized, preventing forced manual travel without secondary external locking hardware.
- Key-Operated Manual Release: A mechanical release lever secured by a key lock enables manual gate operation during power failures or servicing.
- Magnetic Limit Switches: Stroke end detection utilizes non-contact magnetic limit switch sensors and rack-mounted plates to avoid mechanical switch wear and debris accumulation issues.
