Quik Split©	Quik Tran©
The Quik Split© frame design allows the machine to be separated into sections to accommodate lighter and fasters 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.
