Patent for the automatic bolt tensioning device
Based on the idea that bolt tensioning devices don’t have to be screwed on the bolt ends anymore, AS Tech developed an automatic bolt tensioning device.
The developed automatic bolt tensioning device with a patented technique assure to our customers a time saving of 60% while using the axial tensioning technique.
Field tests as well as independent analysis from our customers in the wind turbines branch as well as steel manufacturers confirmed our prognosis.
The new development for this technique was accompanied and co-financed through the European Union, funds for regional developments.
We would like to thank the Ministry of economy, middle – sized businesses and energy of the federal land North Rhine Westphalia for its assistance.
Contact us to get more information about this trendsetting technique.
October 2008:
BodAS Documentation and measuring system
The documentation system BodAS finds more and more application, parallel to providing the requirements and evaluation of bolt connections as well as measuring the remaining tensioning force in already existing bolt connections.
Thus AS Tech provides, beside the customer designed versions for monitoring of screw connections and hydraulic systems, corresponding services where measurements and documentations take place directly at our customers plants.
September 2008:
Husum Wind 2008
AS Tech GmbH covered this year in cooperation with the companies Alki Schraubtechnik and RS Randack Spezialschrauben all categories concerning bolt connections on its fair stand.
Beside the technical and the interesting discussions with our customers from the wind turbine branch – AS Tech supplies almost all manufacturers – new contacts were established especially for the international market.
At this point, AS Tech would like to thank again all its stand visitors. We were glad to receive your positive feedback that approved our work.
August 2008:
Reorganisation of the AS Tech GmbH
With the 10th anniversary of the As Tech GmbH, an integration of an ERP system started this summer. Because of the consequent increasing number of requests of our products as well as the related growth of the company, we will be able to full fill the wishes and targets of our customers in the future with the help of this system.
Moreover, the new manufacturing area, built at the beginning of this year, is completed for the extended assembly area as well as the CNC-machinery.
April 2008 / June 2008:
Miningworld / Neftegas Moscow
For the first time we exhibited with our partner, the company Valmiera, in Russia and Alki Schraubtechnik at two fairs in Moscow. The visitors of „Miningworld“ fair as well as for Neftegas, specialized for oil- and gas industries, showed a big interest for our products. At this occasion, a lot of new contacts were established.
March 2008:
4000 bar aggregate
The company AS Tech GmbH has extended its product portfolio in the branch of its own developed electro hydraulic aggregate from the known maximum pressure of 2500bar to 4000 bar. The hydraulic as well as the electronic controlling are designed corresponding to the customers requirements.
February 2008:
Enlargement of the manufacturing area
At the beginning of February, after three months of construction, the new
extended production areas were ready. For occupancy were also new offices and
social rooms integrated to the production flow.
Thus AS Tech is provided with 1.200m² of production, offices and social
areas for a smooth manufacturing flow.
December 2007:
Mini-EDP
Due to the very large demand for the Mini-EDP introduced in spring,
it is currently delivered in series with two equipments variants. Depending
on each operation case, we can equip you with a mobile workshop version as well
as a portable version for different assembly employments.
All Mini-EDP are built in series with oil cooler, which ensures stable oil temperature under continuous use.
October 2007:
Husum Wind 2007
Because of the very larger power and dimensions of the wind turbines,
the axial screw tensioning technology is getting a greater and greater
importance in the wind energy market.
Beside the particular developed screw tensioning cylinders for the wind
energy, the AS Tech Mini-EDP as well as the screw documentation system
BodAS fulfilled the customers’ expectations.
By this occasion, AS Tech would like to thank you for the high attendance
as well as the interesting discussions during the Husum Wind 2007 and looks
forward to the 2008th exposition.
September 2007:
Formation as tool maker
In September 2007 AS Tech hired the first apprentice as tool maker in the field of manufacturing devices.
After a successful examination as skilled worker in the field of turning
technology and an unlimited employment of the young skilled worker in the internal
manufacturing, AS tech continues to educate formation students on a high quality
standard which provide future safety of its own products.
August 2007:
Heavy load lifting system

Apart from the screw tensioning technology, As tech works also in a broader
application field such as the heavy load cylinder series, HMC.
Faithfully to our principals, we develop in this application field special and highly
efficient solutions corresponding to your requirements.
According to the heavy load cylinders, we develop and build the appropriate pump units
for the synchronous control of the desired number of cylinders.
June 2007:
AS Tech at Husum Wind 2007
In this year AS Tech company will be represented again at Husum Wind..
On our booth you will be informed about all news regarding highly loaded bolt
connections and in particular the axial tensioning procedure.

Service for Wind Energy Plants

We offer immediately a new service for our customers:
The monitoring and documented maintenance of bolt connections.
Due to our experience of many years as manufacturers of bolts and hydraulic
clamping devices, we use our acquired knowledge while providing this service
at the customer’s location
With the support of our documentation system BodAS, our customers receive
an accurate evaluation of the conditions of their bolt connections and plants
as well as our implemented work according to the determined real values during the work.
Thus the problem of controlling the carried maintenance and its results is voided.
March 2007:
Mini-Pump

Mainly for maintenance and applications at hard reachable places, we have developed a new electrical pump.
With a total weight of 30 kg, this new pump can reach a volume flow up to 3 l/min and
a max. pressure up to 2500 bar, with a simple and user friendly handling.
The new solid aggregate has a shock-proof frame that protects it against
roughest surrounding conditions.
Of course, we can also deliver this type with a wireless remote control to
pressurise and depressurise with integrated storage for comfortable and safe use.
For further information, please contact us.
January 2007:
CobAS
Since the beginning of 2007, the first series of conical bolt connections were developed and built by AS Tech.
In the design M56, 16 pieces of these conical bolts transmit the torque in a coupling.
Assembling and disassembling is ensured quicker and safer in comparison to the former used
fitting bolts - taking all advantages of axial tensioning at the same time.
Conical bolt connections can be established with the same tool used for the tensioning
process, to introduce the pre-tensioning force to the bolt ends. This also ensures a
technical as well as an economical advantage against competitor products.
