DR - Casters Starting Force Testing Machine

Designed in accordance with European standard EN12527 and national standards GB/T-14688 and GB/T-14687, the system uses an electric cylinder to simulate the load and a servo motor and ball screw to drive the casters to move horizontally, enabling the "caster rotation performance test" and "caster steering performance test".

Testing items:

1) Caster rotation resistance coefficient: The real-time force in the same direction of rotation and the vertical gravitational force of the caster are detected to calculate the rotation resistance coefficient.

Calculation formula: u1 = F1 / W

Where:

u1 - rotation resistance coefficient;

F1 - rotational resistance force of the caster or wheel, in Newton (N);

W - rated load of the caster or wheel, in Newton (N).

2) Caster steering resistance coefficient: The real-time force in the opposite direction of steering and the vertical gravitational force of the caster are detected to calculate the steering resistance coefficient.

Calculation formula: u2 = F2 / W

Where:

u2 - steering resistance coefficient;

F2 - steering resistance force of the caster or wheel, in Newton (N);

W - rated load of the caster or wheel, in Newton (N).

3) Caster life test: The running speed, stroke, and cycle times can be set to conduct a life test. 

Testing Items

Starting Force Precision Test

Static Friction Starting Force Measurement:

1. Measurement range: 0 - 5000N (accuracy ±0.5% FS), resolution: 0.1N, capture the critical force value when the casters transition from static to rolling.

2. Supports horizontal/vertical direction testing, simulating the starting performance under different installation postures.

Rolling Resistance Analysis: Dynamically test the resistance when the casters roll at a constant speed (0 - 1000N), generate resistance-speed curves, and evaluate energy consumption efficiency.

Multi-condition Simulation Test

Load Adjustable Test: Set the test load (0 - 2 tons) to verify the impact of load on starting force and rolling resistance.

Ground Type Simulation:

1. Replaceable test platforms (smooth steel plate, rubber floor, tile, carpet) to replicate the friction characteristics of on-site ground surfaces.

2. Optional temperature and humidity control module (-20°C - +80°C, humidity 10% - 95% RH) to test performance changes under extreme conditions.

Intelligent Data Management

Real-time Data Acquisition: Synchronously record peak starting force, average rolling resistance, speed-resistance curves, and test environment parameters.

AI Diagnostic System: Analyze data anomalies (such as sudden changes in starting force, excessive resistance fluctuations), and locate defects such as bearing jamming or wheel surface deformation.

Report Generation: One-click export of PDF/Excel reports, supporting QR code traceability and integration with MES systems.
