Features and benefits

Comfortable panoramic rops cabin

The steering column and the ergonomic arrangement of the operating controls and compaction measurement devices ensure safe operation and help prevent tiredness. Special cabin bearings serve to cushion vibrations. Thanks to her innovative design, the windshield lowers the noise level. Excellent circumferential visibility, even in reverse gear, is established by a chamfered engine hood and a very compact design. In addition, a swiveling seat can be installed as an optional feature. Also available with air conditioning.


The state-of-the-art low-emission diesel engines that are at work in all weycor compaction rollers are up to the standards set by everyday heavyduty operation. Substantial power reserves and efficient water cooling serve to spare you trouble, even at extreme outside temperatures up to 55°C and on problematic grounds. Their durability and low fuel consumption account for their cost-effectiveness, their special engine bearings for a noticeable reduction of the noise development.

Front frame and drum

The entire front frame – with the exception of the crossbeams – is welded in order to ensure maximum stability. On wet and cohesive soils, the optional front and rear scrapers serve to remove accumulated material.The smooth drum can be converted into a pad foot drum by attaching an optional segment kit. The drum unit can easily be dismounted without a lifting tool. The front frame and the drum provide the static force.

Articulated pendulum joint

All weycor compaction rollers are equipped with robust, maintenance-free articulated pendulum joints. They cause the front and the rear end to run in a single track and create a very low center of gravity. With an angle of 35 degrees and a pivoting angle of 12 degrees, an exceptional maneuverability is ensured.

No-spin axle

Thanks to its permanent differential lock, the no-spin axle provides for the best traction and maximum climbing power, which applies to all weycor compaction rollers at all times. Whenever different rotational speeds at the wheels are caused by operation on winding routes, the differential lock is automatically deactivated and will not be re-activated unless the wheels run synchronously again. The no-spin axle is a standard feature of all weycor compaction rollers.


In order to ensure quick and trouble-free maintenance, all relevant aggregates are easy to reach via the engine hood, which can be opened widely. Maintenance-free or low-maintenance components, such as the vibratory system or the articulated pendulum joint, serve to further reduce the time and effort to be spent on maintenance.


Perfect adaptation to different types of soil is ensured by the high pressure-dependent control by Bosch-Rexroth. By double-pump system and a continuous tractive force adjustment automatically provides the axle and the roller drum with maximum traction – without any intervention on the part of the driver. This results in an automatic traction control and a noticeably improved climbing ability, especially in areas such as dike and embankment construction.


This optional feature allows you to use the power of the hydraulic units that the compaction roller is equipped with to full capacity, in a particularly efficient way. Use ECO-Mode to reduce the diesel engine revolution by approx. 400 r.p.m., as compared to the nominal rotation speed, without any loss of power of the hydraulic system. While the vibration frequencies and the centrifugal forces remain constant, the noise exposure both for the driver and the environment as well as the fuel consumption are reduced by up to 30%.


2-stage vibratory system with high compaction capacity. Two frequencies and two amplitudes can be selected for surface and deep compaction. Big exterior bearings greased by an oil bath guarantee long inspection intervals.
