Where the WPA 120 Is Installed in Australia

Heavy conveyor head drives in mining and quarry operations, large chemical processing paddle mixers, cement plant bucket elevator drives, and industrial kiln rotation auxiliaries. At 60 kg, the WPA 120 enters the heavy-duty industrial segment where two-person lifting or mechanical handling is required for installation, and continuous-duty reliability is the primary selection criterion.

When to Choose This Model

The WPA 120 covers the below 6.15 kW. Step to WPA 135 for 7 kW+ applications. Choose cast iron over aluminium when the application involves sustained vibration, belt-tension side loads, outdoor installation, or ambient temperatures above 45 degrees C.

For materials, configuration variants, efficiency data, lubrication, and selection methodology, refer to the WPA/WPS Series overview.
