Trackmaster® TMX428 Stress Treadmill Overview
The Trackmaster® TMX428 Stress Treadmill is a heavy-duty, medical-grade treadmill engineered explicitly to interface with and be controlled by leading cardiac and pulmonary stress testing platforms:
▸ Ultra-Quiet Zero-Start Drive: Powered by a 4 HP continuous (6 HP peak) high-torque drive motor that delivers smooth zero-start acceleration to prevent ECG baseline artifact.
▸ Industry-Leading Deck Space: Features an expansive 22″ x 63″ running belt and a 500 lb patient weight capacity, offering broad clinical accommodation.
▸ Patented MasterTrack® Technology: Built-in v-guide tracking alignment completely eliminates off-center belt drift without manual maintenance.
Clinical Features & Patient Safety Systems
Engineered to ensure seamless protocol execution, low patient impact, and instant emergency intervention:
Linear Actuator Elevation: Delivers smooth, quiet grade adjustments up to 25% elevation for precise graded exercise testing (GXT).
Low-Profile Cushioned Deck: Low-to-the-ground step-up height and shock-absorbing deck isolators reduce joint stress and ensure safe boarding.
Self-Calibrating Telemetry: Automatically calibrates speed and elevation parameters to ensure repeatable diagnostic stress protocols and reduce service downtime.
Comprehensive Safety Features: Prominent emergency stop button, full wrap-around safety handrails, and a patient safety tether line.
Optional Standalone Controller: Also available as the TMX428CP model, featuring an integrated manual and programmable control console.
