Make an impact in the field

When your day starts, your CTOS service truck is already in your driveway—stocked, outfitted, and ready. You head to a customer site to evaluate a bucket truck with a finicky boom. You connect diagnostic software, study schematics, trace hydraulics, and bring the machine back to life. Later, you’ll swap out worn components on a digger derrick, verify dielectric integrity, and close the day with precise documentation—all while collaborating with a support team that has your back.

You’ll work across respected brands—Load King, TEREX, Manitowoc, Elliott, and National Cranes—servicing boom trucks, cranes, bucket and dump trucks, digger derricks, utility trucks, and more.
