Pacesetter of development

Our aim is to be upfront with market developments and to

act instead to react. Therefore we simulate the world of

tomorrow and already have the answers on changed

conditions when others diagnose the paradigms.

We use our own know-how and complete it by external

expert know-how punctually. Our measure is to produce

economical, safety-conscious and for the purpose of our

customers.

This way we assure that Pfaff-silberblau is a synonym for

lifting, turning and moving ("lift, turn and move") worldwide

also in the future.

Motion meets technologyIn the fast-moving drive engineering market, the pronounced tendency to blur the line that separates mechanical and electri-

cal systems is giving rise to a whole new set of challenges, which are bound to have a lasting influence on our industry at both

a domestic and – above all – international level. This change requires a new type of cooperation, which must be fitted to face

up to these challenges and meet new requirements. Pfaff-silberblau and ALLTEC Antriebstechnik can now offer future-oriented,

bundled sets of drive systems. Classic Pfaff-silberblau elements, along with the wide range of products offered by the specialist

in cubic screw jacks, worm gears and linear drive units, are now available under one roof. Our single-minded objective is to

expand the frontiers of drive engineering – on a worldwide basis.

Experience meets innovationThere are two stages to every innovation process: first the creation of a solid technological basis, followed by delivery of the

advance in question. In the case of Pfaff-silberblau and ALLTEC Antriebstechnik, two further stages are added: reliability and

flexibility – in order to react promptly to each situation. There is now seamless integration throughout the product range of screw

jacks, quick-lifting jacks, worm gears, mechanical linear systems and drive systems – plus their corresponding accessories.

Specialists in mechanical engineering, industrial machine and plant construction, and the supply of factory equipment all place

maximum trust in the highly competitive quality of Pfaff-silberblau products, as do in-house maintenance and servicing

departments.

Quality meets serviceInterchangeable drive-system elements increase quality and provide for ease of servicing, which in turn results in improved

operating safety. Pfaff-silberblau and ALLTEC Antriebstechnik represent reliability to the power of two. From consulting,

mutually reinforcing experience and engineering services to improved onsite and field service, the user can only profit from the

synergies that this alliance offers in the areas of maintenance, servicing, installation, calculation, legal conformity and so on.

Extract from our catalogue

EC Directive 94/9/EC, better known as „ATEX 95“, to which all new installations and equip-

ment, including non-electrical equipment for installation in potentially explosive areas, must

conform has been in force in the EU since 1 July 2003. To make the worm gear screw jacks

usable for operation in potentially explosive areas and in order to be able to provide them with

a CE and explosive area marking, the manufacturer must perform a range of measurements

and analyses. These include the calculation of the maximum temperature, a comprehensive

hazard analysis and finally the adaptation of the jack to the customer's specifications and

requirements.

Pfaff-silberblau also supplies worm gear screw jacks and linear drives according to the new EC

Directive 94/9/EC (ATEX) for use in potentially explosive areas. The ATEX brochure offers an

overview of the equipment groups, equipment categories and zone allocations available.

Useful informationImproving on existing trends in order to shape the future.

Flexibility is the number-one requirement where a spontane-

ous ability to spot trends and convert them into useful

developments is concerned.

Pfaff-silberblau and ALLTEC Antriebstechnik make full use of

their international technological expertise to set their own

benchmarks in this fast-developing market.

In the specific field of drive engineering, increased automation and ease of

operation are in tune with the ever-greater importance given to the precise

control and monitoring of lifting, lowering, feed and swivel mechanisms.

Areas such as miniaturization, controlled automation, intelligent drive

systems and sensor technology, technology transfer and combination,

and integrated and mechatronic systems have gained major development

status, or have even turned into real applications. Given that mechanical

engineering, machine-tool technology, rail and road technology etc. are in

a state of constant ongoing development, Pfaff-silberblau and ALLTEC

Antriebstechnik also offer electromechanical drive-system elements and

complete drive-system solutions designed for universal applications.

This catalogue contains all the data required for carrying out an informed

selection from the widest-possible range of different worm gear screw

jacks. And answers to your own specific task-requirements, along with

solutions designed to turn your product into a successful and high-quality

overall concept. If you are also interested in recommended special solu-

tions for Linear Motion Precision Screws and Linear Motion Devices,

please ask for the appropriate additional catalogues. Do not hesitate to

contact us if you have any query.
