This Altec D947TB is a mounted digger derrick — sometimes called a utility derrick or pole-setting truck — a type of specialist work machine designed for drilling holes, setting utility poles, and handling heavy loads in powerline, telecommunications, and utility construction applications. Altec is a well-established American manufacturer of equipment for the utility and telecommunications industries, producing aerial work platforms, digger derricks, cranes, and related vehicles for electric cooperatives, municipalities, and large utility contractors worldwide.
This 2002 example is built on a Freightliner FL112 carrier chassis powered by a Caterpillar C10 diesel engine rated at 365 horsepower, paired with a 10-speed manual transmission. The chassis is equipped with air ride suspension and a locking rear differential — a combination the seller notes is particularly hard to find in this specification level — making it well suited to challenging terrain and demanding work environments.
The Altec digger derrick unit itself offers a 24,000-pound lift capacity and a sheave height of 47 feet, giving it the reach and strength required for full-scale pole installation and wire-stringing operations. The digger drive is two-speed, allowing the operator to match auger speed to ground conditions. Four outriggers provide the stabilised footprint necessary for safe operation under load, and a front hydraulic mechanical winch is fitted for additional pulling and rigging capability.
The truck has covered 93,647 miles from new and has accumulated 2,210 PTO hours, reflecting the balance between road travel and on-site working time typical of a utility fleet machine. The seller reports single ownership throughout its service life, with the truck having been operated by a utility company. It is described as clean.
