Prüfmaschine für mobilen PrüfserviceA test bench for traction testing of the lifting equipment gives safer and more accurate results compared to a simple visual inspection.

For efficient testing, without shipping costs and minimal downtime, a mobile testing station can be used to perform the test on-site.

DYNA-MESS offers a testing machine that can be mounted in a service vehicle and be easily transported from site to site for testing lifting equipment.

Optimized for mobile testing

In comparison with the standard machines, this test bench is especially designed to be transported on-site. 

  • The design has been optimized with the FEA method to reduce the weight of the machine and to be mounted in a service truck.
  • The machine is equipped with a special quick release clamping tool to rapidly test different types of lifting equipment.
  • The machine is easy to operate with a control system with standard testing procedures that can quickly be programmed and run.
  • Documentation of the test results


Machine types and variations

Frame construction

  • Fixed inside a vehicle, not portable (for test in a service vehicle)
  • Portable (for test outside the service vehicle)
  • Extendable for testing specimens with different length


Nominal force

  • As requested by the customer, typically 20 t (200 kN)


Length of the machine

  • Adjusted to the vehicle of the customer, typically ca. 4 m


Control

  • Only data display, not possible to save the results to transfer them on another computer for analysis
  • Read RFID tags for a unique identification of every lifting equipment

Ropes, chains and lifting equipments testing

For more than 25 years, DYNA-MESS is the reference for testing:Zugversuch an Drahtseil

  • Ropes (wire cable, fiber cable, synthetic ropes, ...)
  • Cables (crane cables, bridge cables, ...)
  • Chains (anchor chains, mining chains, ship anchor chains, ...)
  • Slings
  • Lashing
  • Straps
  • Crane hook
  • Hooks, shackles and other lifting equipments
 

Horizontal vs. vertical test machines

Schwingprüfung an DrahtseilHorizontal test machines or benches are used for many applications. Horizontal test machines usually have one test axis, a large cylinder stroke and are perfect to perform tests on large scale parts (cables for example).

For specials purposes, vertical test machines can be used. They are usually suited for small nominal forces and when a small stroke is required.

 

Force up to 1000 t. (10.000 kN) - Clamping length up to 20 m - Stroke up to 6 m

Prüfmaschine zur SeilprüfungWith its modular system, DYNA-MESS can offer a lot of different versions of its machines.

The nominal force of the machine can be several tons (100 kN, 250 kN, ...) up to more than hundred tons (2500 kN, 3000 kN, 3500 kN, 6000 kN). Some special machines can even reach a nominal force of 1000 t. (10.000 kN).

The machine can be delivered with a clamping length up to 20m (and even more!) and a stroke up to 6m.

The clamping length and the stroke are always adapted to the product to be tested and to the customer needs.

 

Hight quality machine design

Zugbank für SeilprüfungFor more than 25 years, DYNA-MESS offers a robust machine design with a self supporting test frame filled with a special polymer concrete. With that, DYNA-MESS machines have a super high rigidity and good damping properties.

 

Type of tests

Here are some test examples that can be performed with a horizontal test machine:

  • Tensile strength
  • Stretching
  • Elasticity modulus (Young's modulus)
  • ...

Prüfmaschine für KranseileSome specifics measurable variables can also be added on request as torsion loading.

For dynamic tests, the performances of the part are investigated with a cyclic load. The part is usually tested until failure occurs.

 

Stretching machine

In addition to tensile tests, the machines can also be used to stretch the parts as part of the production process. This is possible with the easy-to-use DYNA-MESS software that can be configured for a wide range of applications.
