GrizzlyDrive® Series Drum Motors are manufactured for demanding belt conveyor applications, from mining and aggregate to ship loading and power generation. The high quality precision-made components are engineered to withstand harsh, abrasive, and dusty environments. The motor, gear reducer, and bearings are enclosed and protected inside the drum, and designed for 80,000 hours of service life before maintenance, increasing safety, while decreasing maintenance and operating costs.

The all-enclosed design and robust construction of the GrizzlyDrive® reduces cost of ownership, and provides belt conveyors with reliability, longevity and performance in the harshest of conditions. GrizzlyDrive® Series Drum Motors are available up to 500HP, with a wide range of diameters, belt speeds, lagging, and options to suit various belt conveyor applications. The optional VDG patented IronGrip lagging extends the life of the belt and other rotating conveyor components, such as rollers and idlers. VDG also offers a unique Belt Cleaner that effectively removes residual materials without wearing or damaging the belt.

Lower Cost of Ownership

With all components enclosed inside the drum, and the motor coupled in-line to the gear reducer, the GrizzlyDrive® operates at 96% mechanical efficiency, reducing energy consumption with up to 30% in savings.

The all enclosed design eliminates guarding and costly routine maintenance intervals required with traditional external motor and gearbox conveyor drives, reducing cost of ownership and operating costs.



Increase Longevity and Reliability

The GrizzlyDrive® Drum Motor is manufactured with high quality precision-made components and engineered for 80,000 hours of service life before maintenance. It features robust mechanical seals and cylindrical roller bearings that sustain high levels of belt tension, shock loads and vibration. The VDG Oil Cooling/Conditioning unit maintains optimal oil viscosity and ensures a cooler running motor, extending the life of the drive. Learn how IronGrip lagging also contributes to the reliability and longevity of the GrizzlyDrive®.

Increase Safety

External conveyor drive components such as the motor, gearbox, pillow block bearings, chains, and chain guards pose hazards to workers and require guarding. These traditional drives also require regular maintenance cycles increasing personnel contact and the potential for injury.

With no external components protruding outside the conveyor frame, the GrizzlyDrive® eliminates maintenance, hazards and guarding associated with traditional drives. This compact, maintenance-free drum motor is a safer and more efficient conveyor drive solution.
