Test stands for bicycle racks according to DIN EN ISO 11243

Bicycle racks must be able to withstand high mechanical loads and guarantee long-term safety on the road. The DIN EN ISO 11243 standard defines the requirements for load capacity, durability and safety under realistic operating conditions. Special test stands precisely simulate these loads to ensure the reliability of the racks.

Vertical dynamic test (DIN EN ISO 11243, section 5.9.3)

Test procedure:

• The luggage carrier is set into a vertical, sinusoidal vibration.
• The system gradually reaches a frequency of 7 Hz in order to avoid overloading due to moments of inertia.
• Automatic stop of the system after reaching 100,000 cycles (target number of cycles according to DIN EN 11243)

Adjustable parameters via PLC control:

• Total stroke between 10 and 18.24 mm.
• Stroke frequency between 1 and 8 Hz.

Lateral dynamic test (DIN EN ISO 11243, section 5.9.4)

Test procedure:

• The luggage carrier is vibrated laterally by swinging from side to side.
• The vibration occurs at a frequency of 1 Hz over an adjustable angle of ±5 to 7.5° on both sides of the symmetry plane.
• Automatic stop of the system after reaching 100,000 cycles (target number of cycles according to DIN EN 11243)

Adjustable parameters via PLC control:

• Swivel angle up to ±7.5°

Operation of the test stands

Control system:

• The test stands are conveniently operated via a touch panel with PLC control.
• All necessary parameters such as number of cycles, speed/frequency, stroke and swivel angle can be set here in accordance with standard specifications.

Flexible mounting:

• The luggage carriers to be tested can be flexibly attached to a profile carrier or directly to the bicycle frame, which ensures practical testing.

The test stands for bicycle racks in accordance with DIN EN ISO 11243 enable a comprehensive assessment of the mechanical properties and ensure the quality and safety of the products. Precise control and flexible mounting options simulate realistic load scenarios that meet the requirements of road traffic.
