The innovation concerns a rearing board section for double-sided independent enlargement the disputes of a ripper for education a Vario ripper.

As part of the repair, renewal and recycling, a number of measures are planned, where, starting with the repair, a machine operation is required.

This includes, in particular, the renewal of surface courses over the full width of the lane with and without milling and, if necessary, the introduction of a leveling layer, as well as the removal of the gutter in larger continuous lengths.

Also the renewal, i.e. the complete restoration of an existing road surface or Parts of it, after removal of the corresponding parts, fall under this area, whereby the repair measures again depend of the type of damage and the severity of the damage.

This includes the laying of bituminous sludge, the installation of cold or hot sludge Thin-layer coverings,

as well as heating, loosening and reinstalling the old bituminous pavement.

A device is used for this procedure, which is the first to be processed Bituminous layer usually replasticized by adding heat, then loosened up, laid again according to the profile and pre-compacted.

Normally this treated layer is covered with new bituminous in a second work step Mixture that is paved using a separate paver is covered and brought to the desired final state by further compaction equipment.

However, as is known, it is also possible to prepare the removed material separately and the amount removed by adding bituminous mass to supplement, whereby / in the sense of Recycling process, the removal usually together with additional aggregates and additional binding agent is processed.

In this context, the so-called Variö rippers are becoming increasingly important because they are too machined surfaces, viewed in the working direction, do not always have a uniform width.

For example, bulges are provided on one or both sides along the routes to be processed, the task of parking niches, depots for grit or, in the case of narrow streets, of passing points take over.

The separate removal of the surface of these bulges, be it with compressed air devices or the like., is very labor-intensive and does not guarantee absolute evenness between the bulges and the subgrade of the slab to be worked on.

With this in mind, it is an object of this invention to provide a ripper by means of ripping board sections to be supplemented with a Vario ripper, the stepwise widening of the to be processed Planums can be carried out precisely and without any significant expenditure of time.

in connection with the extension width controlling pressure cylinder enables the production of a level, flat tear-open area regardless of the one within the setting area set width.

In the interest of a safe, bend-free storage of the sword-shaped support profile, it is intended to limit the bending moment by ensuring that the length ratio between the sword-shaped support profile and the one directed upwards Gap is determined so that the partially or fully extended sword-shaped support profile in each position at least more than half of its length in the area between the pile girders remains.

To the guide for the sword-shaped support profile to secure and its damage by breaking into the crevice or dirt from the construction site to prevent, it is provided that each of the upwards and / or downwards Gaps closed by a louvre-like, bellows-like or stretchable cover is.

Furthermore, it is sometimes advisable to attach the pressure cylinder directly to the basic device,

In each hollow box profile 3 a sword-shaped support profile 3.3 is continuously arranged, the by a widening paragraph 3.8 upwards in the inner cross section 3.1 of the hollow box profile 3 Slidably held in one plane. In parallel, there is a hydraulic one on each hollow box section 3 Pressure cylinder 6 attached, in some cases also directly on the base unit 1, namely on the Board support 2.2 can be arranged, and at its extension end on a "äurch a connecting Push bar 5 worn articulation eye 5 * 1 directly with the sword-shaped support profile 3.3 is connected.

By retracting or extending the pressure cylinder, the sword-shaped support profile 3.3 in the case this example extended up to approx. 65 cm or any possible intermediate dimension and then retracted again will.

In every operating position, more than 50% of the extension value is stored in the hollow box section 3.

In the area of the gap opening 3.2 "below" are at a corresponding distance on the sword-shaped support profile 3.3 ploughshare-like ripping teeth 3.4 attached, cfie after extending the task of the Take over the loosening of the pavement over the widened carriageway.

In the area of the ripping teeth 3.4 is a protective device attached to the penetration of milled material or the like in the box girder the gap opening 3.5 prevents.

An adequate protective device can also be provided for the upper gap opening 3.5.

On each extension side is the ripping board section 3.6 or a height adjustment 2.3 is provided in its immediate arrangement area, this enables the formation of a frame end edge and also prevents the lateral Escape of debris.

The entire Vario unit formed by the hollow box profile 3 and its internals is arranged at the same height in the cutting area in front of the rippers of the basic unit, with the basic unit having standard widths of 2.50 m to 3 m, with a separate part on each side, which then can be extended on the respective side.

The basic widths mentioned can therefore be a maximum of 2 χ 0.65 m, i.e. to a total width of 3.80 m or, with a basic width of 3 m,. can be set to a total width of 4.30 m.
