Safe, Easy Operation Makes 3100GT Ideal for New Drillers, State Agencies

Cost-efficient mobilization, safety features (below) and ease of operation have made the 3100GT a valuable rig for training new drillers while providing the operating versatility and comfort desired by experienced drillers. State agencies and engineering firms especially appreciate the ease of operation and added safety.

Control panel on passenger side puts distance or line of sight between operator and on-coming traffic.
Raising the mast with the winch system retracted, before telescoping up the winch reduces ultility-line collisions. Winch is fully functional at all positions.
Manual controls provide tactile feel.
Electric controls provide for safe, hands-free operation.
Control panel and driver side both include a safety E-stop. Safety pull cable between the control panel and the head adds another layer of safety.
