DMW 220: Economical demolition of weir wall

Verfasst am by kemroc-hitzner

Using a KEMROC DMW 220 cutter wheel on a 32-t excavator, a massive concrete weir wall was cut into individual segments.

A disused weir in Stadtilm (Germany) was demolished to allow fish to pass through this section of the Ilm River again. To break down the massive weir wall, demolition contractor, JeFra Bauservice GmbH & Co. KG used a KEMROC DMW 220 cutter wheel on a 32-ton hydraulic excavator. This made it possible to dismantle the concrete body precisely, economically and without harmful vibration …

KDS 30 in a railway tunnel: Cable ducts removed quickly

Verfasst am by kemroc-hitzner

A KEMROC KDS 30 diamond saw on a compact excavator cuts out concrete cable ducts from the floor of the tunnel to make room for a new tunnel lining.

The Elleringhauser Tunnel in Germany’s Hochsauerland region is being completely renovated. To install new tunnel lining, concrete cable ducts had to be removed from the bottom of the tunnel wall. Specialists from the EET consortium (Max Bögl/Marti DE/Marti CH) chose an 8-tonne compact excavator and a KEMROC KDS diamond saw to cut the concrete ducting into manageable pieces …

KRX 70: Bored pile wall securely anchored

Verfasst am by kemroc-hitzner

Using a Powertool KRX 70 drive unit with milling attachment, recesses are made in bored piles, into which reinforced concrete spurs are poured at a later date.

Near Osterode in the Harz Mountains (Germany), the intake section of the Söse dam is being renovated. In the process, the holding dam had to be resealed using a new bored pile wall. This wall is strengthened at the top and bottom with two reinforced concrete belts. To excavate recesses in the bored pile wall to attach the reinforced concrete spurs, Umwelttechnik & Wasserbau GmbH uses one of their own 24-tonne excavators with a KEMROC KRX 70 Powertool drive unit with longitudinal milling attachment. As a result, the project was completed within the required specifications and on schedule …

KRC 140: Pipeline trenching for water supply

Verfasst am by kemroc-hitzner

A KRC 140 Bullhead milling attachment excavates trenches in hard sedimentary rock to connect new elevated tanks to the drinking water grid.

In the district of Neundorf in the municipality of Rosenthal am Rennsteig, two new elevated tanks will supply water for the future. A large pit had to be excavated in bedrock before trenching for foundations and pipelaying could start. Mounted on a 26-tonne excavator, a KRC 140 Bullhead milling attachment from KEMROC completed all excavation work and trenching within expected tolerances and within expected timeframe …

EKT 100: A task requiring precision

Verfasst am by kemroc-hitzner

To underpin a building, rock below the façade is carefully and precisely milled out by using a 25-tonne excavator with an EKT 100 drum cutter attachment.

To underpin a building in Paderborn, the construction company Karl Immig used a 25-tonne crawler excavator with a KEMROC EKT 100 rotary drum cutter. This was used to excavate rock from underneath a building with precision and with little vibration to create space for the necessary foundations. Thereafter the excavator-milling combination excavated trenches for services – and thanks to a 3D excavator grade control system, it was extremely fast and accurate …

KR and EK cutters: A double dose of precision tooling

Verfasst am by kemroc-hitzner

A KEMROC KR 120 rotary drum cutter and an EK 40 chain cutter complete site preparation work efficiently and accurately.

The “Königsteiner Höfe” is a new residential and commercial quarter being constructed in the middle of Königstein im Taunus in the German state of Hesse. Acting as a subcontractor to the Köster Group, the company Höfling Erdbau was engaged to complete the site preparation work. Using two excavators with cutter attachments from KEMROC, the contractor put all the bored pile walls in place and put in the drainage systems efficiently and to the required accuracy …

Demolishing concrete using the Cut & Break method

Verfasst am by kemroc-hitzner

At the Kassel sewage treatment plant, rainwater overflow basins are being replaced. The ring-shaped edge of the concrete basin is cut with a DMW 220 cutter wheel.

The city of Kassel in the German state of Hesse is gearing up for the future. At the sewage treatment plant, two aging stormwater overflow basins are being replaced by larger ones. To demolish the massive, ring-shaped concrete rims of the basins, the contractor Schnittger decided to use technology from KEMROC. Last year, a DMW 130 cutter wheel was used to demolish the rim of the first basin. This summer, a larger DMW 220 cutter wheel was used on the second basin to complete the work faster …

Economical trenching in rock

Verfasst am by p638627

Prior to the construction of a large factory and warehouse, a KEMROC EKT 100 milling machine on a 25-tonne excavator is used to excavate trenches and pits for strip and individual footings.

At an industrial park at its hometown, Haiger in the German state of Hesse, the construction company Wirth secured a major contract. Before construction of a new factory and warehouse could start, they had to prepare the site and install foundations. A 25-tonne excavator with a KEMROC EKT 100 milling attachment was used to work out the footings through solid and fissured rock – saving time and money compared to the use of hammer and bucket.

Transforming a bunker to a residential complex

Verfasst am by p638627

Concrete demolition with hydraulic excavators and KEMROC milling attachments: A former high-rise bunker is being transformed into a residential complex.

In the German city of Koblenz, a high-rise World War II bunker is given a new lease of life. The mighty building made of solid concrete is to be transformed into a high-quality residential complex. To start this transformation, contractor HR Abbruch had to make some structural changes to the building. Milling technology from the manufacturer KEMROC played a key role in the initial phases of this project. A large excavator with milling attachment completed demolition work with low noise and low vibration levels while in close proximity to neighbouring residential buildings.
