December 11, 2014 – Terex now offers an insulated, retractable 4th section on its General 80 digger derricks.
Saying it’s the first of its kind in the industry, the 4th section is made from fiberglass (replacing a non-insulated, steel 4th section on previous models) and designed for increased insulated digger derrick reach heights. Crews are able to set poles and perform line work with an 80-ft digger derrick. The ability to retract the 4th section fully into the other boom protects the new 4th section from potential damage when not in use. WATCH the video for a walk-through.
