Truck & Crawler Drilling Equipment

Mahaffey utilizes one of its many truck or crawler mounted rigs for jobs requiring high mobility. No matter the conditions, whether they are overly saturated or at a high elevation, our truck or crawler mounted rigs can get the job done. With a sensible torque capacity of 150,000 ft./lbs. and a 360 degree turntable, holes of 100 feet in depth are possible in the worst of conditions.

Applications for our most diversified group of machines include: tie back/shoring systems, limited duration foundation projects, and conductor and rat holes for the oil industry. Mahaffey can get in, get the job done, and get out without holding up other trades (subcontractors). Our machine’s capability and suitability to difficulty site conditions translates into a significant savings in time and money for an otherwise costly job.
