Office Chair Five-Pedestal Pressure Resistance Tester

Product Overview

The Office Chair Five-Pedestal Pressure Resistance Tester is a specialized device designed to evaluate the load-bearing capacity and structural integrity of office chair pedestal bases (five-point support systems) under simulated user weight and dynamic stress. It replicates real-world seating conditions, including static pressure, uneven weight distribution, and cyclic loading, to ensure compliance with international safety and durability standards (e.g., BIFMA, EN, ISO). This machine helps manufacturers assess pedestal deformation, weld strength, and material fatigue to optimize chair design for long-term reliability.

Key Features

Five-Pedestal Simulation:
- Simulates pressure on all five pedestal points simultaneously, mimicking uneven weight distribution (e.g., lateral leaning or rotational stress).
Testing Modes:
- Static Load Testing: Applies a fixed vertical force (up to 2000 N) to measure deformation and maximum load capacity.
- Dynamic Fatigue Testing: Cycles loads (10–100 cycles/min) to assess material fatigue and weld durability over time.
- Peak Force Measurement: Records maximum force before structural failure.
Precision & Customization:
- Adjustable load range (200–2000 N) and speed (1–50 mm/min) to replicate diverse usage scenarios.
- Configurable pedestal spacing (15–50 cm) to accommodate various chair base sizes.
Advanced Safety & Accuracy:
- Overload protection, emergency stop function, and real-time overload alarms.
- High-precision load cells (±0.5% FS) and linear encoders for displacement measurement.
User-Friendly Operation:
- Touchscreen HMI with preloaded test protocols (BIFMA X5.1, EN 1335) and customizable parameters.
- Real-time data display, automatic failure detection, and exportable reports (CSV/Excel/PDF).
