Quality and expertise from Lower Saxony

STICHWEH plant technology and treatment systems

Many national and international customers approach us with this quality statement in order to successfully realise their projects in the stone and earth industry.
We are recognised worldwide as experts in plant engineering and processing systems for the stone and earth industry: from sand and gravel extraction to extraction and professional classification. In order to provide these services efficiently and sustainably, even under the most difficult conditions, we rely on the highest quality standards.


Every application for the extraction and classification of raw materials has very specific requirements in terms of extraction conditions, material properties and performance targets.
Our design department takes these into account and creates a concept on this basis, which is then implemented.

Further development and repair

As all technical documentation for the machines is available at STICHWEH, further developments, retrofitting and restructuring can be carried out from a single source.
Equally important is the availability of documents and data in the event of Spare parts and repairs.

Service and assembly

STICHWEH fitters, who are deployed worldwide, play a decisive role in the implementation. They work on call directly on site and ensure that the supplied units or
complete systems run flawlessly.

Our quality promise:

Rolf Sürig

We stand for performance:
Just in time.

Anja Gröhlich

Our sustainability promise

Against the backdrop of increasingly rapid global change, we all have an obligation to systematically find ecological and social solutions in order to fulfil our responsibility to society as a whole. This is why we believe that performance and sustainability must be combined.

This is why we have developed the STICHWEH BIG FIVE , which show the attitude and developments on which our commitment to sustainability is based.

1. Maschinen-Verantwortung
Nachhaltigkeit No 1 Maschinenverantwortung

For us, this means that we pay attention to the responsible use of machines in our projects: with the lowest possible emissions and integrated into the infrastructure of the respective project in the best possible way.

This also includes the reuse of our machines as second-hand machines and resource-saving spare parts handling.

Average service life of a STICHWEH scraper: 40 years in two-shift operation.
The majority of STICHWEH machines are still in use as used machines.
Spare parts are not only delivered just in time, but are also handled sustainably.
We have many long-running parts in-house and carry out repairs directly on site.
We can manufacture new parts directly on the basis of existing drawing templates.

2. Herstellungs-Verantwortung

The design, construction and assembly of customised machines are carried out from a single source and not by individual suppliers. Our machines are planned and built centrally in Thüste. This enables us to ensure responsible raw material processing and supply chains.

  • Raw material-efficient handling in the development of scrapers
  • Centralised production: design / construction / assembly from a single source
3. Ökologische Verantwortung

Less is more. We continue to develop the technology and design of our machine solutions according to this principle: less energy consumption, less water consumption, fewer emissions. Our aim is to help ensure that gravel pits operate as sustainably as possible and can continue to be used as nature reserves after operation.

  • Waste water treatment
  • Low-emission drives
4. Gesellschaftliche Verantwortung

Part of our principle of responsibility is our safety system. From design and assembly to commissioning, we ensure machine safety and quality. The result: durable designs and decades of average STICHWEH machine use.

5. Mitarbeiterverantwortung

As a regional employer, we stand for diversity and equal opportunities. As a training company, we also want to secure and expand the future for the region. Together with other companies in the Industrieverein Alfeld-Region e.V., we are committed to this.

  • Diversity and equal opportunities
  • Occupational health and safety
  • Regional employer

2023 "Digital Now"

We have introduced a new business organisation system via the "Digital Jetzt" programme, a federal funding programme that supports SMEs in driving forward digitalisation: from production and inventory processes to personnel planning, costing and order management, everything now runs centrally and digitally - and therefore faster and more efficiently.

2022 Bucket wheel no. 1000

On 28 November 2022, the thousandth STICHWEH bucket wheel went to North Rhine-Westphalia, where it will be used by gravel pit operator Heinrich Schmitz GmbH for washing and dewatering raw materials and building materials that are important for the region.

2021 Sustainability

The STICHWEH BIG FIVE have been developed as part of the STICHWEH sustainability campaign "Kiss the future". These show the attitude and developments on which STICHWEH's commitment to sustainability is based.


Stichweh is celebrating its 100th anniversary in 2019 under the motto "Heavy Birthday!". What began shortly after the end of the First World War as a metalworking business repairing agricultural machinery, among other things, has grown consistently over the decades to become today's internationally successful supplier of systems for the extraction and refinement of sand and gravel.

2015 Modernisation

STICHWEH is continuing its ongoing modernisation process: this includes the acquisition of new production facilities, the expansion of internal structures and processes and investment in sustainability through the construction of a 67 kWp photovoltaic system.

2005 - 2014 Expansion

Further development of STICHWEH into an internationally expanding company with branches worldwide: Foundation of STICHWEH LLC USA in 2005.

1994 Export

75 years after the company was founded, STICHWEH has supplied over 1000 bucket wheels, 600 bucket wheels and 100 sand and gravel processing plants to numerous European and non-European countries.

1990 Digitisation

The design and creation of workshop drawings has been completely converted to high-quality, extremely powerful CAD computers.

1960 – 1980 Internationalisation

STICHWEH products also have a good reputation in other European countries and overseas. Machines are exported to Austria, France, Yugoslavia, Denmark, Canada, the Netherlands, the USA and other countries. The largest scraper KS 1000 with a bucket capacity of 10 mᵌ was delivered to Denmark in 1978.

1965 Economic miracle

Up to 40 scrapers are sold each year and the number of bucket wheels sold increases from year to year. The company grows. Construction of today's Hall V and the administration building on the factory premises.

1962 First bucket wheel

STICHWEH develops bucket wheels to solve the dewatering problem when conveying gravel and sand. The constantly growing demand and the new development of larger bucket wheels, especially for suction excavators, ensure the expansion of the entire STICHWEH portfolio.

1955 Power expansion

An efficient machine factory grows out of a craft business. The first trade fair appearance took place at the Bauma in Munich. Halls II, III and IV are built in the following years.

1945 New beginning

Father and son create a factory for the production of machines for sand and gravel works from old stock. Hall I is extended and the first modern machine tools are purchased.

1919 Company foundation

Fritz Stichweh founds a company in Thüste on 1 May to manufacture and repair machinery for agriculture and the surrounding industry.

Production of grinding plants, washing and sorting plants as well as transport systems for lime, coal, stone and sand.

The first scraper plants for gravel extraction and machines for processing are delivered to the Wolfsburg area for the construction of the Volkswagen plant.

Fritz and five years later his younger brother Walter join their parents' company.

With the simplest of means, repairs are carried out for agriculture and the surrounding industry in order to provide the population with the bare necessities.
