Tracked Stair Climbing Transport Chair Analysis Report

Device Description and Intended Use

The product shown in the images is a battery-powered, tracked stair climbing transport chair designed to enable individuals with limited mobility to safely ascend and descend stairs. This device is used for patient and individual transfer in emergency evacuations, hospitals, nursing homes, and buildings without elevators, for wheelchair users or persons with walking difficulties. The primary function of the product is to facilitate transfer by easily overcoming stair steps thanks to its motorized track system.

General Condition and Assessment

According to the details in the images, the device appears lightly used and generally in good condition. No significant wear, rust, or major damage has been observed on it. The paint on the metal parts is largely preserved, and its wheels are clean. This suggests that the device has been used carefully or has not been used for a very long time. No documents or box contents are visible in the images. A total of 1 unit of transport chair has been examined.

Physical and Mechanical Analysis

The physical and mechanical components of the product have been thoroughly examined, and the following observations have been made:

• Chassis and Frame: The device’s yellow and black metal chassis has a sturdy structure. There are no visible dents, bends, or cracks. Welding points and bolted connections appear problem-free.
• Seating Area: The black seating area, made of a fabric or tarp-like material, is taut and free of any tears or rips.
• Track System: The black rubber tracks, which enable the device to ascend and descend stairs, are in good condition. No breakage, wear, or deformation has been observed on the track teeth.
• Wheels: The front and rear wheels appear clean and functional. There is no excessive wear or damage on their tires.
• Safety Belts: Below the seating area, there is a red tension strap and a black safety belt with a red button locking mechanism on the frame. These parts are visually complete and intact.

Electronic Components

Immediately below the seating area, there is a black box, understood to house the device’s motor and power supply. There are no cracks, breaks, or deformities on the casing of this box. This structure indicates that the device is a battery-powered model. However, no comment can be made from the images regarding the battery’s capacity, charge status, or health. No control panel or charging cable is visible in the images.

Labels and Other Information

No label or writing indicating the brand, model, serial number, or technical specifications could be read on the device. Only a small yellow label with a warning pictogram (a crossed-out drop icon) indicating that liquid should not be spilled on it is visible on the side of the track mechanism.

Potential Risk Assessment

Based on visual inspections, no obvious defect (such as crushed cables, deep cracks in the casing, rust on critical parts) that would pose an immediate risk of failure has been detected on the device. The product’s overall structure, mechanical components, and visible electronic units are well-preserved. In this state, the device is assessed to be mechanically functional. However, a definitive statement cannot be made without testing the battery status and the full functionality of the electronic components.
