Gearbox Design

Every Drill Rig manufactured by EDR is equipped with one of our custom designed and built gearboxes, after many hours of field testing our gearboxes have proven to be reliable. Key to the design of professionally built gear drives is the skills to determine their operational duty. The EDR team determine the design life to comply with both ISO and AGMA standards, and optimize this design using FEA and in-house computer programs to determine the best solution.
