Terex Utilities introduced a new generation of the General 65 digger derrick for utility transmission applications during the virtual Electric Utility Fleet Managers Conference (EUFMC) in June 2021. The General 65 MAX boasts greater capacities through all boom angles, but especially in the work zone. Whether the transmission crew needs low boom angles for digging holes and pulling a full auger flight of dirt or unloading pad mount transformers at high boom angles, the General 65 MAX has superior lifting capacity in all positions.
At a 10-ft radius and fully retracted, it can lift 22,620 lbs. With the optional X-Boost, the General 65 MAX features 25,000 lbs. capacity at high boom angles, which is 26% more power than its predecessor. X-Boost adjusts hydraulic pressure to increase load handling capability and enables strong performance for lifting at high boom angles.
In addition, crews will experience the highest work zone capacity when digging holes. “At zero degrees with the boom fully extended—which is the most challenging position to work from—the General 65 Max can lift almost a ton, representing over 80% increase,” said Joe Caywood, director of marketing. “It is important that a digger derrick can dig a hole, lift a full flight of dirt on the auger, and set the pole from one truck setup to keep crews productive. Out and down as well as radial outrigger configurations provide the best load chart for lifting capacities."
The General 65 MAX leverages many Terex pioneered digger derrick design features such as trapezoidal dual hydraulic cylinders, which work to stabilize the boom during digging and rotating; a retractable rectangular boom; and filament wound fiberglass third boom section.
Other common features will make life easier for technicians and operators. “Terex Commander and General series of digger derricks have standardized controls, which supports operator performance by delivering the same look and feel regardless of which Terex digger derrick the operator is used to,” said Caywood. Radio controls and other control station options are available so controls can be customized. Technicians will also experience ease of maintenance working on a simple, full-pressure hydraulic system and overall maintenance access to features such as the collector block and extension cylinders.
The General 65 MAX can be equipped with a variety of tools and accessories to increase productivity. Options include several styles of transferrable pole guide arms, full lineup of Terex augers to match digging conditions, and material handling jibs.
