Digger Derricks

Terex General 65 MAX

The strongest digger derrick in the transmission market - 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. The increased capacity ranges from 26% at high boom angles with X‐boost to 80% at lower boom angles specifically below 0 degrees (subject to chassis and unit configuration due to stability).  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. It is important that a diggers 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.
