This equipment is mainly designed in accordance with the European standard EN12527 and the national standard GB/T14688. It uses a large roller as the driving wheel to drive the tested casters. With the addition of obstacles, it can conduct tests such as "obstacle crossing test", "long-distance walking life test", and "load-bearing test". It is microcomputer-controlled and can set different operation modes for distance and obstacles, such as running forward for 2 minutes, stopping for 2 minutes, then running backward for 2 minutes, stopping for 2 minutes, or running for 3 minutes, stopping for 1 minute, and then continuing. The load application uses a stack of weights for direct pressure, which more realistically simulates the test environment and conditions. It is controlled by a touch screen, making the setting and operation very convenient. It can display the walking time and distance in real time and is suitable for testing the wheels of suitcases, roller skates, office furniture wheels, trolleys, and industrial casters, etc.
Function Description
1) Dynamic Experiment: It is possible to set the drum to rotate forward or backward, the time for forward rotation and backward rotation to pause, with up to ten consecutive change processes, and the total process can be cycled up to 9,999 times.
2) Long-distance Travel Experiment: The running time and mileage can be set. The machine will stop when the preset time and mileage are reached.
3) Static Load-bearing Experiment: The equipment is equipped with 20 weights of 25KG each, with a total weight of 500KG, and the weights can be added for static load-bearing testing when the drum is stationary.
4) Castor Explosion-proof Experiment: There is a photoelectric switch at the installation position of the castor to detect whether it is broken or damaged. If it is damaged, the machine will stop.
5) Bump Simulation Experiment: By adding obstacles on the drum, the bumping when the castor travels over obstacles can be simulated.
6) Curve Analysis: Curves can be drawn to visually analyze the changing trend, and the mileage, time, and speed can be recorded to support the generation of reports.

Core functions
Roller-driven fatigue testing
Continuous rolling simulation:
1. Roller diameter: 300~1000mm (customizable), rotational speed: 10~200rpm (stepless speed regulation), simulating continuous rolling of casters (equivalent to 100 kilometers per day).
2. Load range: 0~2 tons (expandable to 5 tons), precisely controlling vertical pressure and lateral torque.
Multi-surface simulation: The roller surface can be replaced with modules (smooth steel plate, sandpaper, rubber, textured), reproducing different ground friction characteristics.
Environmental coupling test (optional)
Temperature and humidity cycling: Temperature range -40℃~+80℃, humidity 10%~95% RH, verifying material thermal aging, low-temperature brittleness and metal corrosion risks.
Salt spray/dust test: Simulating high salt spray or dust environments according to ASTM B117 standards, testing sealing performance (IP65/IP67) and corrosion resistance.
Intelligent monitoring and diagnosis
Real-time multi-parameter collection:
1. Load force (accuracy ±0.5% FS), rolling resistance (±0.1N), wheel temperature rise (infrared thermal imager ±1℃), vibration spectrum (5~2000Hz).
2. 3D laser scanning (optional) for real-time monitoring of wheel surface wear depth (±0.01mm), generating wear cloud maps and life prediction curves.
AI failure warning: Machine learning algorithms analyze abnormal noise frequency, temperature gradient, etc., to predict risks of bearing jamming or wheel cracking, automatically stopping the machine and generating reports.
Data traceability: Automatically export PDF/Excel reports (including rolling resistance curves, thermal imaging maps), supporting integration with MES/ERP systems.
Technical highlights
High-precision disc drive:
1. Servo motor closed-loop control, rotational speed accuracy ±0.1rpm, torque fluctuation <±0.5%, supporting long-term continuous operation.
2. Modular roller design, quick replacement of surface modules (smooth, sandstone, rubber), suitable for casters with wheel diameters of 80~500mm.
Safety and energy conservation:
1. Fully enclosed protective cover (pressure resistance ≥3MPa), emergency stop, overload protection, meeting ISO 13849 (PLd level) safety standards.
2. Energy feedback technology recovers 30% of the electricity used during testing, standby power consumption <150W.
Equipment advantages
High efficiency and accuracy:
1. 72-hour continuous testing is equivalent to 5000 kilometers of actual rolling, with data repeatability error <±0.5%.
2. Supports custom test scripts (such as step loading, variable speed rolling), adapting to diverse testing needs.
Flexible adaptation
1. Compatible with swivel casters, fixed casters, and models with brakes, load range 50kg~2 tons (expandable to 5 tons).
2. Optional vertical static load crushing test module (maximum pressure 10 tons).
Cost optimization
1. Laboratory testing replaces outdoor road tests, reducing overall costs by 60%.
2. Through early defect interception, reduces after-sales maintenance costs by over 70%.
Standard compliance: Built-in 20+ test procedures including ISO, GB, DIN, etc., generating global certification reports with one click.
Application scenarios and industry value
Production quality inspection: Batch fatigue testing of casters before leaving the factory to quickly identify material defects or poor assembly.
Logistics and warehousing: High-frequency rolling life verification of AGV carts and shelf casters.
Medical equipment: Silent and low-resistance durability testing of casters on hospital beds and operating tables.
Certification testing: Compulsory testing items such as ISO 22883 cycle life and DIN 15106 rolling resistance.
The single-station roller fatigue testing machine for casters, through an innovative design of roller drive and intelligent monitoring, accurately reproduces the rolling wear and fatigue attenuation of casters in real scenarios, helping enterprises achieve quantitative assessment of product lifespan and zero-defect delivery. Whether it is to enhance the durability of industrial casters or ensure the silent and safe operation of medical equipment, this device can serve as a core tool for caster research and production, safeguarding brand competitiveness and user trust.
