Benefits/Features
Extreme-Duty, Single-Phase Fan-Cooled Motor
The SNER electric hoist is equipped with a 60-minute H4-rated motor which is unmatched in a single-phase offering. Built for extremes, the SNER delivers proven performance in the most demanding applications.
PENDANT PLUG-IN CONNECTIONS
Saves valuable time on setup and maintenance. “Quick disconnect” replaces typical competitive hard-wired designs.
Self-Adjusting Maintenance-Free Brake
With no brake coil to fail or discs to replace, the electromagnetic pull rotor brake on the SNER is self-adjusting and virtually maintenance-free.
SEALED PROTECTION
Appropriate for both indoor and outdoor applications, including harsh environments. Gaskets throughout the trolley provide for an IP55 rating.
Oil Bath-Lubricated, Heat-Treated Gearing
Harrington’s own heat-treating process increases the overall hardness and strength of internal parts which run smoothly when immersed in an oil bath. This extends service life by reducing friction, vibration, and heat.
