Hats Off To Mechanics
There are various pieces of machinery that provide the muscle for demolition and rigging projects, from large cranes and excavators to smaller equipment like skid steers, scissor lifts, articulating boom lifts, and lulls, as well as pneumatic hammers, welding equipment, generators, compressors, etc. R. Baker & Son employs an expert team of diesel and combustion engine mechanics, technicians, millwrights, and electricians that regularly inspect, maintain, service, and fuel this essential equipment to ensure its safety, availability, and top performance.
Having an arsenal of rigging and demolition equipment standing at the ready for any project that comes up is one of our greatest strengths, as is the readiness of our maintenance and repair team to report to any job site that requires their services to get malfunctioning equipment back up and running. This ensures that equipment breakdowns are rectified as soon as possible and don’t turn into costly downtime events.
Though they don’t often work in the spotlight, these team members provide the backbone that keeps R. Baker & Son job sites running smoothly. Hats off to our crack team of mechanics, technicians, millwrights, welders, technicians, and electricians for a job well done.
