The CT380-130 and CT430-140 tandem vibratory rollers from JCB are 3.8 and 4.3 tonne machines that are powered by the EU Stage V JCB by Kohler diesel engine, providing 36.5kW (49.6hp).
The CT380-130 has an operating weight of 4.1-tonnes, generating an operating linear load of 15.8kg/cm. With a centrifugal force of 41-59kN, the machine has a vibrating frequency of 50-60Hz and an amplitude of 0.50mm. The drums can be offset to either side by up to 80mm and the roller is capable of 30% gradeability with vibration operating, or 40% when not compacting.
The larger CT430-140 weighs in at 4.5-tonnes and offers a linear load of 16.4kg/cm. With the same frequency of 50-60Hz and a 0.50mm amplitude, the heavier machine delivers a centrifugal force of 44-63kN. The roller has the same drum offset capability and gradeability as its smaller stablemate. Both models have a maximum working speed of 10km/h.
There are steps to both sides of the machine, providing easy access to a sliding operator seat with arm rests, a safety switch in the seat and a seat belt monitoring system. A compact metal dashboard provides a clear view of operating data and machine health and there are working lights to the front and rear of the machine for maximum visibility in poor light conditions.
