Fixture construction of lifting devices for industrial production & clean room

Some industrial parts or components are simply too important and too expensive to be damaged in the production process or in the cleanroom. It is therefore worthwhile providing a remedy and safeguarding with the right lifting equipment. From lifting beams and lifting pins to lifting and transport crane systems. FRITZ Vorrichtungsbau specializes in industrial lifting equipment. The more difficult the problem or task, the more important it often is that we are also on board for consultation and development or validation. As I said: expressly also or especially for clean room requirements.

 

OUR CORE COMPETENCE IN LIFTING DEVICES

FRITZ is your universal partner for the development, parts production, assembly and validation of special lifting devices. Everywhere where:

  • Load-bearing connecting elements are safety-relevant
  • processes need to be optimized or tool-free handling is required
  • Standard-compliant tests are required,
  • cleanroom is required or series with a wide range of variants are produced
  • Consulting, co-development and design is required

EXAMPLE: LIFTING DEVICES FOR ASSEMBLY - ALSO IN THE CLEANROOM

Lifting and handling devices for the assembly of larger components - also for clean rooms.

The example shows an easy-to-move lifting crane for various handling tasks in cleanroom assembly, cleanroom cleaning and cleanroom packaging. Ideal for feeding components to different stations in in-house logistics.

EXAMPLE: LIFTING BEAMS FOR ASSEMBLY - ALSO IN THE CLEAN ROOM

Lifting beams for component assembly & component handling - also for clean rooms.

At first glance, lifting beams like these look simple. At second glance, however, they often conceal complex details. However, these are what transform an unsafe and inadequate process into an uncomplicated, safe and fast work step. Rely on FRITZ expertise in lever traverses, generally with tool-free and intuitive operation.

Other customized lifting beams. Adapted to the application.

EXAMPLE: LIFTING SUPPORT FOR INTERNAL LOGISTICS - 100 % BREAK-PROOF

The customer had broken a bolt 3 times in the previous years during in-house transportation. A huge problem with expensive semiconductor and high-tech components!

Often a big problem hinges on just a small bolt. That's why we develop load handling attachments or lifting pins with amazing load capacities. The load suspension device shown here has to achieve a life cycle of 16,000 load suspensions. Below you can find out what we do to achieve this - immense! But: It is better to invest once more in new bolts before a "product worth millions" in the seven-figure range falls down once more.

EXAMPLE MOUNTING BOLT: FRITZ AS A PARTNER FOR THE ENTIRE PROCESS

Since the end of 2024, we have been developing and manufacturing locating bolts (M8-M16 fit with 4 screws) on behalf of customers for lifting applications that perform safety-critical functions. The bolts are used as load-bearing connecting elements and must withstand defined nominal loads and overloads in a reproducible and standard-compliant manner.
 
Due to the safety-relevant function, a purely mathematical design is not sufficient - a complete process is required:

  • defined overload test,
  • documented acceptance,
  • and CE-compliant approval.

Our role. We take over for these mounting bolts:

  • the technical implementation based on customer calculations,
  • the production-oriented design and manufacture,
  • mechanical testing up to the defined overload,
  • as well as the acceptance, documentation and CE declaration.

This ensures that every bolt variant is delivered in a reliable, traceable and standard-compliant manner.

Technical requirements

  • Nominal load-dependent design per bolt type
  • Overload test: 2-fold or 3-fold above the nominal load specification
  • Testing is carried out mechanically, not just mathematically
  • All standard bolts are additionally tested with nominal load
  • CE conformity per tested series
  • Special attention is paid to the clear separation of test and series components.

 

Testing & hedging strategy

For each new stud variant, a separate pair of studs is manufactured exclusively for the overload test. This pair of studs is deliberately scrapped after the overload test to ensure clear differentiation from the series.

Overload test

The overload test is carried out with a modular test weight set: depending on the required test load, existing weights are used or additional test weights are added if new load ranges need to be covered. This modular concept allows:

  • reproducible tests,
  • Flexible expansion for new bolt types,
  • and an economical series production process.

Standardized overall process

  • Inquiry & offer (development)
  • Creation of 3-D model
  • Calculation of the model by the customer
  • Offer (Hardware)
  • Production of series studs + separate pair of test studs
  • Overload test (2-fold / 3-fold)
  • Nominal load test of all series bolts
  • Scrapping the test studs
  • Acceptance & CE declaration

For whom is this sales case relevant?

This solution is interesting wherever:

  • load-bearing connecting elements are safety-relevant,
  • standard-compliant tests are required,
  • and series with a wide range of variants.

 

Typical fields of application:

  • Special machine construction
  • Lifting and handling technology
  • Fixture and equipment construction
  • Testing and assembly equipment

 

Conclusion

We show with the mounting bolts:

  • how safety-critical components can be industrialized in a reliable process,
  • how calculation, production, testing and CE can be cleanly interlinked,
  • and how maximum safety is achieved through clear separation of test and series components.

Engineering, production and testing from a single source - with documented responsibility.
