Description
Driver Heads – Digger Drives, Output Torque, 4,300 to 20,000 ft.-lb., Two-Speed, Shift-On-The-Fly or Optional Single Speed, Heavy-Duty, Automatic Kick-Down, Maximum System Pressure: 2,750 PSI.
The 75 Series Digger Drive, “Hydrasync” uses a high-efficiency double planetary for high-torque requirements, like foundation anchor installation, and drilling larger holes for piers. The 75 can provide a cost-saving alternative to other single-purpose equipment.
The 75 Series is available with automatic “Kick-down” option (when operations require it). The digger will shift to low-speed, high-torque position while you keep digging. There is no need for an additional hydraulic line to shift the motor. This option requires a motor with a high-pressure shaft seal.
