This was a fascinating job done for Antigo Construction out of Idaho who was contracted to break up a runway at Travis Air Force Base in Northern CA.
These brutal machines are remotely operated and have a 20,000 lbs. guillotine type breaker bar that is used to break (pulverize) concrete down to a depth of 3’ (36”). Not only does the breaker bar bit wear out, but these machines literally destroy themselves over time.
Here's a YouTube video example of this type of machine:

I spent many hours replacing the breaker bar bits and repairing cracks in the mast carriage as well as the frame structure which is also the hydraulic fluid reservoir. Once a crack develops the machine has to be shut down and the failure repaired to minimize the environmental impact from oil loss.
EXPERTISE:
- Commercial Work, Classic restorations, Custom Exhaust, Frames, Structural welding
- Small to large scale piping jobs that operate under high pressure and temperature service, sanitary welding
- Platform construction and repairs including redesigning and or replacement
- Custom fabrication of guards, handrails, safety covers, and shields to comply with OSHA and Cal OSHA regulations.
- Overlay and weld build-up using Stellite and other hard facing Alloys.
