On a wind farm in Texas, a four man crew was covering 2,000 feet of cable per day – loader operator, guide, and 2 men in the trench spreading out the piles.  The first partial day using a Magnum, with a single person operating the radio controlled machine, he covered 2 miles of cable.  Because of restricted access, AT7s and RL26 combinations are widely used on Solar Fields.  Gas lines, utilities, water lines, and all types of trenches can be filled quickly, accurately, and safely.
