Florida, USA-based Esco announces its new Hot Wheel wheel heat indicator decal, intended to warn drivers, maintenance personnel and safety inspectors of possible wheel end, bearing and brake failure during walkaround inspections. The self-adhesive decal is attached to the wheel rim; if the temperature of the wheel exceeds 250°F (121°C) the label’s temperature-sensitive white arrow changes to and remains bright orange, warning of an overheated wheel condition. After the wheel problem has been corrected a new decal must be installed. The company notes that although the Hot Wheel decal will not indicate every instance of a wheel end component malfunction, it will indicate excess temperature for prolonged periods that could cause decreased function or failure of wheel end components.
