7. Compact! Hermetically Sealed Aesthetic design
Space saving compact design
Light weight
Safer than conventional drives

8. Hermetically Sealed – IP67
RULMECA
Motorized Pulleys - the perfect drive unit for corrosive chemicals and abrasive bulk materials:
Copper & steel
Coal
Limestone
Potash
etc.

9. Easy to Maintain RULMECA
Motorized Pulleys – Low Maintenance Requirements (change oil every 10,000 operating hours):
Remove magnetic oil plugs
Wipe off sludge
Drain oil
Refill

10. High Efficiency
The pulley is driven directly by the internal gearbox, giving the Motorized Pulley an efficiency of:
95%
Therefore, less energy is required. This makes Rulmeca Motorized Pulleys to one of the most economical conveyor drives.

11. Extra Thermal Protection
All RULMECA
Motorized Pulleys have 3 built-in thermal protection switches:
Connect to normally closed control circuit
Designed to provide back up to plant current overload protection

12. Rubber and ceramic lagging options Full rubber diamond
Partial rubber diamond
Partial rubber smooth
Full ceramic diamond

13. “Holdback” Options Mechanical Backstops Internal Brakes
External Brake Shafts

14. “Holdback” Options Mechanical Backstop Fastens to Motor Rotor
Mechanical Advantage (up to 100:1 gear ratio)
Protected Environment (hermetically sealed)

15. “Holdback” Options Internal Brake Fastens to Motor Rotor
Mechanical Advantage (up to 100:1 gear ratio)
Protected Environment (hermetically sealed)

16. “Holdback” Options External Brake Shaft
Hydraulic shoe brake (by others) installed on 800H Motorized Pulley
External brake shaft extends rotor shaft through pulley main shaft
