Where the WPA 155 Is Installed in Australia
Large mining conveyor main drives at BHP and Rio Tinto contractor sites in the Pilbara, heavy industrial crushing equipment auxiliaries, large-format rotary drum screens in mineral processing, and heavy sluice gate actuators for dam infrastructure. At 110 kg, the WPA 155 requires engineered mounting and mechanical handling for installation.
When to Choose This Model
The WPA 155 covers the below 14.50 kW. Step to WPA 175 for 15 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.
