JCB VMT390K STATIC SMOOTH DRUM ROLLER

The JCB VMT390K is a static smooth drum roller designed for efficient compaction tasks. It features a front drum with a diameter of 31.5 inches (2.7 feet) and a width of 51.2 inches, delivering a static linear load of 75.4 pounds per inch and a centrifugal force of 1,079 pounds on high vibration setting, operating at a frequency of 55 vibrations per minute and a nominal amplitude of 0.1 inches. The roller’s overall dimensions include a width of 4.2 feet, a height to the top of the cab of 8.4 feet, a wheelbase of 7.6 feet, and ground clearance of 12.1 inches, with an operating weight of approximately 9,535 pounds. Powering the VMT390K is a water-cooled Kubota V2203 engine, a durable 4-cylinder diesel with a displacement of 134 cubic inches (2.2 liters). It produces a gross power of 46.6 horsepower (34 kW) at 2,800 rpm, supported by a reliable mechanical fuel injection system. The engine supplies 45 amps at 12 volts through its alternator and has an oil capacity of 2.6 gallons and a fuel capacity of 20 gallons. The hydraulic system fluid capacity is 13.2 gallons. The roller achieves a maximum travel speed of 6.8 mph. The VMT390K rides on four smooth 8.25 R15 tires and is engineered for stability, control, and effective soil compaction on construction sites, offering a balance of power, maneuverability, and operational efficiency suitable for medium-scale paving and compaction applications.
