Hydraulic crawler cranes offer the best of traditional crawler cranes associated with sheet piling together with the benefits of a mobile crane with their telescopic jib. The cranes have a maximum capacity of 40 tonnes at 1.0m radius and boom lengths up to 30.0m. The modern design enables fully hydraulic control for a smooth and reliable safe operation. The undercarriage extends to 4.500m for full operational duties and retracts to just 3.000m for transportation. These cranes can also work with a reduced capacity on retracted tracks when they are required to work on particularly restrictive sites.
