USE OF EP PNEUMATIC MOTORS AND GEARBOXES PRODUCED BY SET MAKINA

Stronger and Safer Shotcrete Applications in Underground Tunnel

Client Profile:
A manufacturer of shotcrete machines for underground applications sought to deliver consistent and safe performance in its equipment.

Objective:
To ensure continuous and reliable machine operation, achieve uninterrupted rotation in the rotor drum, and meet safety standards with ATEX-certified motors.

Operational Challenge

The client was facing:

  • Lack of ATEX certification in the air motors previously in use
  • Unsufficient power from vane type motor on the previous version
  • Rotor drum rotation issues, disrupting machine operation

SET MAKINA’s Solution

SET MAKINA introduced the EP80 piston motors in this project. Key benefits included:

  • ATEX-certified motors, ensuring compliance with international safety standards
  • Reliable power transmission enabling uninterrupted rotor drum rotation
  • Trial of the EP120 model on larger shotcrete machines for enhanced performance
Shotcrete

“After switching to SET MAKINA EP80 motors, the rotor drum achieved smooth and continuous rotation. The previous interruptions caused by lack of power are now completely eliminated.”
