Double Rail Ultrasonic Flaw Detector FD-GT60 FD-GT60 double-track rail ultrasonic flaw detector is a
double-track rail ultrasonic electric flaw detection vehicle
independently developed by our company. It has excellent defect
detection capability and precision. It has high driving stability,
good maneuverability, low noise and convenient disassembly and
assembly. It can adapt to a variety of rail types from 43kg/m to
75kg/m and comprehensively detect internal defects of rails. The FD-GT60 double-track rail ultrasonic flaw detector has a
maximum travel speed of not less than 20km/h, a maximum detection
speed of not less than 15km/h, a cruising capacity of 60km, and a
braking distance of less than 20m at the highest speed. It has a
fixed-speed cruise function and anti-overturning. The device has an
automatic parking function; has a centering alarm system; consists
of 6 modules, each module weighs no more than 60kg; the wheel probe
consists of 6 70° probes, 2 37° probes and 1 0° probe. It meets the
needs of detecting the damage of rail head, rail waist, middle part
of rail bottom, etc. The wheel probe holder has automatic centering
function, and it can safely pass through 12 kinds of ballasts in
the detection state; dustproof, waterproof and anti-vibration
design. Competent for wind, sand, rain and snow, and other natural
environments; outstanding anti-interference ability, competent for
electrified operation environment; instrument with A, B type flaw
detection data real-time processing, display, marking, storage,
playback function, with distance compensation function, with more
than 200km detection data Storage capacity, with mileage
calibration, speed limit setting, etc., with rich peripheral
interface and compatibility; defect detection capability fully
meets China Railway Corporation "Rail ultrasonic flaw detector
