Safe Zone cab on the Revolution Series single-platform underground bullwheel puller keeps operators comfortable, safe and off the ground when the machine is in use. The company says the cab is an industry first and features a cage-type enclosure designed to reduce the risk of contact with energized environments. It has a digital touch-screen display for diagnostics, machine operations and pull status. A 35-horsepower, water-cooled diesel engine provides the U7500 model with 7,500 pounds of pulling power and can be configured with an air compressor.
