JCB Vibromax is introducing a range of double-drum ride-on rollers for high frequency compaction.

The VMT380 and VMT430 models are both available in two drum widths - either 1,300mm or 1,400mm -, creating four different machines:

• VMT380-130
• VMT380-140
• VMT430-130
• VMT430-140.

Design features include a single-piece exciter shaft, for durability, and front-mounted engine with tapered frame, for improved visibility and weight distribution.

These rollers replace the previous VMT390 and VMT500 in the JCB compaction line-up.

The drive system has been improved to delivers an extra 20% in vibration frequency, to 66Hz, for rolling speeds that are now up to 10% higher than the competition. Gradeability has been improved by 42%, while all models use a mechanical gear shift for smoother starting and braking, JCB says.

Turning radius is 2,380mm for the 1,300mm drum machines and 2,430mm for the 1,400mm-width models. Operators can now choose between single-front, single-rear or twin drum vibration, for more control on smooth finish asphalt layers.

With the engine moved to the front section of the chassis and the larger water tanks now rear-mounted, the operator station is all new. The drive lever now comes with an integrated cutter control, and an optional second drive lever adds versatility. JCB’s automatic vibration control (AVC) system, that cuts off vibration when the roller stops travelling, remains standard on all models.
