Over 30 years of reliable portable field service repair, keeping your job up and running.​

Since 1974, Mouldagraph has maintained and repaired every model of every major brand of mining equipment manufactured in around the world. This includes the largest machines of their kind.

Highly Trained Specialists

Field service on various machines used in mining, oil and gas and other related industries requires specialized portable equipment. In fact, we own and utilize two of the three Squirrel Journal machines being used in the United States today. As the needs of our field service clients have changed we’ve encountered many unique experiences requiring custom fabrication of parts. We have designed and built many special attachments for a number of machines during these field repairs. Mouldagraph is the only mining and related field repair services company that offers this level of expertise.

Our field technicians endure rigorous training and apprenticeship programs in order to ensure exact manufacturer specifications are met at all times during every repair.

Machine Shop on Wheels

Over the years, our field machinists and welders have repaired or fabricated just about every replacement part imaginable and have saved our customers time and money over the cost of new parts and downtime of critical equipment. Our reputation for doing the job right the first time is reflected in the experience of our personnel.

Our field repair trucks carry two of each of the most used portable machining tools necessary to repair and service equipment in the field. We can often save time by running more than one machine at a time.

Job Site Welding

Our welders represent the very best in mine, construction, and related industry equipment repair. As the quality of the weld determines the strength of the repair, a poor welding job can be very costly in wasted preparation and additional downtime. Our welding trucks are fully equipped to provide fast, reliable repair service and our welders undergo extensive training in order to ensure the highest quality of service available in the industry.
