. Posted in Auger Boring Machines

Next Generation

Highly Productive Rack & Pinion pulls the machine back to its starting point on the track quickly - no dogging or winching.

Design Benefits

  • Increased ability to pull auger, steering rods, and push product
  • Increased visibility to the master pusher
  • Low Centerline and Wide Stance provide increased stability
  • Hydraulically assisted clutch is easier and more comfortable to operate
  • No Hook Rollers, machine locks safely to the track
  • Ergonomic operating button allows for feathering the rotation and slow turn of the shaft for easy auger installation
  • Emergency shutdown switch at the operator's station as well as an operator presence tethered switch
  • Vivid graphics guide safe and proper machine operation
  • Updated gauge system includes the improved engine tachometer, engine warning light, & hydraulic thrust pressure reading
The Quik Split frame design allows the machine to be separated into sections to accommodate lighter and faster lifts into and out of the bore pit and aids the operator in being able to facilitate better and safer machine positioning.

Quik Split Quik Tran
The Quik Split frame design allows the machine to be separated into sections to accommodate lighter and faster lifts into and out of the bore pit and aids the operator in being able to facilitate better and safer machine positioning. Quik Tran is the fast return system, made available exclusively from American Augers, as it provides up to 10,000 lbs. (4,536 kg) of push/pull at high speed, and there will be no dogging or winching during retract, as the Quik Tran system engages directly to the machine track. Quik Trans benefit will be easier machine operation in challenging work climates or conditions.

 

Spoil Door
With a Safety-First commitment all American Augers horizontal earth boring machines are equipped with a gravity activated-manual spoil door, which deflects thrown debris from the spoil chamber.
