Custom Air Motor System for a Mining Company's Drag Line

Four custom air motor systems were needed in Australia for a mining company’s drag line. The crane’s winch is powered hydraulically, but the company wanted to protect itself from potential downtime of the hydraulic system by incorporating a pneumatic backup system.

Requirements: 12,000 ft-lb of Running Torque
5 rpm
6 inch Diameter Shaft
Foot Mounted

 Pneumatic Backup System

Solution: A standard PSI Automation 10 hp air motor with an integrated planetary gear box was used. A custom foot mount was fabricated to match the customer's specifications and to correctly balance the suspended air motor system. A custom air piloted Horton air brake was integrated into the assembly operated directly from PSI Automation’s V1 air valve.

Total weight: 1100 lb. each
