The RexONE Descent Control System (DCS) is a multi-function patient evacuation device designed for all
levels of emergency responders. It provides the all versatility of the RexONE system with the added function of its
new braking system. The DCS Hand Brake allows users control of speed while maneuvering down steep descents
and stairwell evacuations.
The DCS Hand Brake contains a Safety Lock Button that when engaged secures the wheel brake rods in a
locked position without constant pressure on Hand Brake. This safety feature allows Responders the opportunity
to rest and reposition themselves during a descent.
The RexONE DCS all terrain tires system provides the ability to rapidly move across a variety of surfaces and
terrains while providing additional traction during steep descents. The tri-fold frame can quickly be folded and
easily stored in it’s carrycase, which also converts into a backpack making it ready for rapid deployment.
The RexONE DCS ergonomic design adjusts in multiple positions accommodating the various physical or
medical conditions responders must confront. The combination of a centered balanced wheels and Telescoping
Pull-Handle allows a single responder 360°maneuverability and agility to quickly move a patient to safety. The
new RexONE Descent Control System provides a braking system that helps responders control their speed during
steep descents or down stairwells.
The RexONE DCS frame consists of a tri-panel system: the 1) Head Panel, 2) Center Panel, and 3) Foot Panel.
Each panel is framed by tubular T-6 aircraft aluminum and embedded circular vent to provide increased structural
strength while maintaining a lightweight and sleek profile. The DCS Brake System consist of forged alloy dual cable
brake lever with heavy duty steel cabling and housing. The single brake level controls the dual wheel brake rods
and the locking Safety Button on the brake handle secures the brake rods in a locked position to prevent rolling
when locked. Articulating hinge joints connect the three panels together which can adjust to multiple transport
positions. These transport positions can quickly be changed by a simple pull of the Red Release Cables located
between both the Head Panel and Foot Panels.
The Head Kickstand and Foot Kickstand can be extended to transform the RexONE DCS into a patient
treatment cot and quickly fold under the Head or Foot Panels to be deployed as a mobile stretcher. A telescoping
Pull Handle folds under the Foot Panel, then can quickly be released and locked in position for use. The protective
wheel fenders guard and protects patients from contact with the tires. The color-coded Velcro fender flaps allow
responders to match left and right wheel fenders to the correct frame side for quick assembly.
