Third Coast Equipment RT16 Trench Diesel Roller Controlled by radio frequency remote control, this Third Coast trench roller does not require the operator to be in physical contact with the machine. When used in trenches, this means the operator can stand at grade while the machine works below grade, improving operator safety. Features The use of radio frequency remote-controlled operation improves communication between the operator and the machine by removing the line-of-sight requirement found on traditional infrared remote-controlled trench rollers Radio frequency not only operates with greater stability and over longer distances but also operates through objects on the job site such as trench shoring cross bars, which can block traditional infrared systems This trench roller features expandable padfoot drums that are ideal for cohesive (clay mix) soils This trench roller is powered by a Yanmar Tier 4f diesel engine Equipped with remote emergency stop activation Intelligent remote control pairing Third Coast Equipment RA29 Dual Drum Roller Motor Yanmar 3TNV80F - Diesel Power 20 hp Speed with vibration 1.5 mph RPM 2400 Vibration Frequency 2520 vpm Centrifugal Force 15,300 lbf Cooling Liquid-cooled Fuel tank capacity 8 gal Weight 4035 lbs Drum Diameter 20.5 inch Dimensions 75 in x 51 in x 33.5 in (LxHxW)
