The GP62K pusher leg (also known as "Empujador Perforadora" in Spanish) is a simple yet robust pusher leg designed specially for the G656W jackleg drill. Made with aluminum alloys first developed for use in aircrafts, the GP62K pusher leg has a large piston diameter to reduce pressure on contacting parts and increase pusher leg life. The feed controls are placed conveniently on the pusher leg for operator comfort.
