Terex Utilities has completely redesigned its A330 and A650 auger drills, including enhancements to control systems, transition to a hydrostatic-drive transmission, radio remote control, and remote-diagnostics capability. The new operating system allows the truck, unit controller, and unit engine to communicate, supporting the application of radio remote controls. The drills feature automated functions, including auto brake release, inner-Kelly retract stop, inner-Kelly slack stop, home position, return-to-center, and dig depth. The return-to-center feature allows the operator to return the auger to the position used previously, which assists in keeping the hole at the proper diameter and the proper vertical position throughout the dig.
Optional telematics are available for use in conjunction with a supplied cellular or internet connection. The drills are available with a command post and joystick controls, with a new design that allows the display monitor to be mounted at the drill or used remotely with radio controls. According to Terex, the new control-system design eliminates nearly 40 percent of the hydraulic fittings and hoses previously used.
