Worm gearing drives our products. 

Worm Gear Drives are inherently self-locking and typically cannot be back-driven. This provides a safe secondary mechanical braking means to hold and control the load which is well-recognized as such by the industry.  Hoist Worm Gear Drives can hold a load for infinite periods of time as well as handle long lifts without problems unlike a standard load brake which can heat up and wear out.  Hoist Worm Gear Drives, with less moving parts and no required adjustment, have proven to be lower in maintenance in contrast with alternative hoist drives which generally involve multiple gear sets in addition to a mechanical load brake.

Due to their inherent friction, Worm Gear Drives also act very similar to brakes by retarding motion.  For that reason, brakes are generally NOT required on all SATURN Worm Gear Trolleys, Drive Tractors or End Trucks.  Heavy capacity, high momentum systems operating without VFD controls are sometimes the exception.  In these cases, the trolley or crane may roll more than the acceptable limit without a brake.

For High-Ratio Worm Gear Hoists, there are some major advantages over other hoists.

• High-Ratio Worm Gear Hoists Conform to CMAA, ASME and OSHA guidelines
• High-Ratio Worm Gears safely control the lifting load without the need for a Mechanical Load Brake.
• High-Ratio Worm Gears are inherently Self-Locking thus these hoists are very capable of acting as 2nd stopping brake and also holding up a load.
• Worm Gear Hoists have very Low Maintenance as fewer moving parts lead to fewer repairs
