HAMM’s H 20i C P Series Rollers
For compacting soils or deep recycled asphalt lifts, the padfoot drum of the H 20i C P series from HAMM, a Wirtgen Group company, Antioch, Tennessee, offers a range of weights. The larger of the series—the 20- and 25-ton “C” model machines—offer additional torque to the front drive drum assembly, when paired with a blade to allow dozing and reclamation work. When a project requires placing deep recycle lifts in tunnels where fume may be a concern or performing dozing activities near quarry faces, the roller can be operated by remote control to keep workers out of harm’s way. Here’s how it works.
When the crew comes to an area where there’s safety concern, they can put the H 20i C P in remote control mode with the press of a button in the cab. The operator puts on the remote control harness, which communicates with the H 20i C P via Bluetooth. He stands a safe distance, up to 50 feet [with a maximum operating range of 325 feet without obstructions with batteries fully charged], to control the roller’s movements.
Interfacing with the machine in this way is designed to be identical to operating from the driver’s platform: As soon as the remote control is activated, a specially developed lamp console above the cab indicates whether the roller is ready for operation. “Green” means the roller can be started, stopped and steered by remote control. Furthermore, the vibration frequency and working speed can be adjusted, and the dozer blade can be operated, if applicable.
