XQ-115 Wheelchair Load-bearing Block 
1. Simulate real load conditions to support comprehensive performance testing
1.Standard counterweight (commonly 50/70/90 kg, including child size) + ergonomic shape (fits the seat back), precisely simulating the user's weight and center of gravity.
2. Dynamic Durability: Combined with the dual-roller road test equipment, it can measure the fatigue strength and lifespan of the frame, wheelset, and drive/braking systems.
3. Static strength: Test the load-bearing capacity, deformation resistance and ultimate load capacity of the frame, seat back, armrests, and casters.
4. Safety Performance: Verify the stability of braking and deceleration, slope anti-slip function, and obstacle clearance safety; identify and eliminate risks such as structural fractures and loosening.
5. Dimension Measurement: Place according to the GB/T 18029.7 standard to ensure accurate measurement of seat/wheel dimensions.
II. Establish a unified testing standard to ensure the quality of production and incoming materials
1. Mass production inspection: Load the finished wheelchairs with the standard load and quickly determine whether they meet the internal control standards of the enterprise and the national standards, thereby preventing products with insufficient load capacity from entering the market.
2. Incoming material control: Verify the load tolerance of components such as seat cushions, frames, and wheel sets, and control the quality of the supply chain at the source to reduce post-sale risks.
