Starlifter CX-3T

The CX-3T crawler crane has proven itself in civil engineering and other industries as an invaluable solution to lifting, in conditions restricted by height and width, or where difficult access defeated other plants.

Compact, rugged and highly manoeuvrable, the versatile CX-3T, with 360-degree slew, rubber tracks and the telescopic boom has been used extensively under and above ground. This light crane is easily portable by air, water, rail and road.
