Highly efficient production of rumble strips

Rumble strip kit for cold milling machine W 50 DC / W 50 DC i

Quick and simple production of rumble strips

The rumble strip kit from Wirtgen is the ideal choice

for milling rumble strips into asphalt or concrete

road pavements in a highly efficient process. Vehicles

driving over the milled-out grooves that run along the hard

shoulder generate vibrations as well as clearly audible tyre

noises to alert inattentive or overtired vehicle drivers.

In this way, car or truck drivers are warned immediately

that they are drifting off their lane. The tried and tested

rumble strip kit enables durable and highly wear-

resistant rumble strips to be produced at high milling

speeds. The kit is ideally suited for use with the Wirtgen

W 50 DC / W 50 DC i cold milling machine.

Optimizing road pavements in a

cost-effective process

A W 50 DC / W 50 DC i is milling rumble strips into the hard shoulder of a road at high speed

The heavy, robust frame structure has been designed

for tough milling jobs and extended operation.

Exceptionally high milling speeds of up to 27 m/min

can be achieved with the rumble strip kit designed for

use with the W 50 DC / W 50 DC i.

The ancillary kit ensures precise maintenance of both

the milling depth and the specified intervals between

the rumble strips.

Economically efficient production is guaranteed by low

operating costs.

When driven over, the rumble strips generate vibrations and tyre noises

Choice of two tried and tested profile designs

Intelligent technology for increased safety

In the USA, mainly the so-called rumble strip profile

is used. The design of the rumble strip profile wheel

enables it to mill 10 mm to 20 mm deep grooves into the

pavement at precisely specified intervals.

The sinusoidal profile, on the other hand, is more com-

mon in Europe. Combined with a special milling drum

profile, the sinusoidal profile wheel creates a sinusoidal

milling contour both in and transverse to the direction of

travel. The rumble strips created in this process minimize

noise emissions while generating high levels of vibration

inside the vehicle at the same time.

The milling drum is driven via the mechanical drive system of the W 50 DC / W 50 DC i

Depending upon requirements, the rumble strip kit can

be used to produce a rumble strip or sinusoidal profile.

Wirtgen additionally offers a non-profiled wheel for the

quick and easy removal of road markings.

Rumble strips can be produced at speeds of up to

27 m/min – depending on the material to be removed,

job site conditions and rumble strip contour.

The operator can work at ease as the operator’s

platform is completely isolated from the up-and-down

movements of the profile wheel.

Sinusoidal profile (Europe)

The hexagonal sinusoidal profile wheel produces an oval, sinusoidal milling contour in the direction of travel

Eminently suitable for use in residential areas: the sinusoidal profile reduces noise emissions

but increases vibration levels

Specially arranged cutting tools create an oval, sinusoidal milling contour transverse to the direction of travel

Ease of operation for perfect milling results

Optional control unit for increased operator comfort

The rumble strip kit has been designed with ease

of operation, milling precision and high daily perfor-

mance in mind. These features are enhanced even further

by the optional control unit. It is arranged within easy reach

and in the operator’s immediate field of view and can be

used to adjust different milling parameters and display

travel speed, distance travelled and similar readouts.

The milling drum can easily be switched from the left to

the right machine side. Mounting the rumble strip kit to be

used is just as easy. Nine weight slabs weighing 550 kg

altogether can be added separately as required. In addi-

tion, the kit has been designed so as to allow milling right

up close to obstacles such as manhole covers.

Intelligent concept

The milling drum can be mounted on the left or right side of the machine

The additional machine control system simplifies the work process

The direction of travel is corrected via bearing rod

and front mirror to ensure best working results
