YOUR SOLUTION FOR
RAILROAD HOT BOX & DRAG DETECTION
Hot wheels and hot boxes are a major threat to any railway
operation. A hot box can lead to severe damage to your axles
which could trigger a derailment. Hot Box and Hot Wheel
Detection systems are solutions that decrease faults to
guarantee a safe railway operation. They can monitor the
temperature of axle-bearing boxes and wheel rims and
reduce the risk of catastrophic failures.
Hot boxes or hot bearing detectors (HBD) are used to
measure the temperature of the journal bearings of a train.
They typically consist of two infrared eyes on each side of the
tracks looking up at the train’s bearings. They register the
radiation from every journal bearing that passes over them. If
a bearing reaches the maximum temperature for safe travel,
the detector will flag and count it as a defect. Because
bearings can burn off in as little as three minutes, hotbox
detector installations are extremely common on many
railroads. Find out how CDL Group of Companies can provide
Hot Box and Drag detection solutions to your railroad system.
