In China, the high-speed railway construction is growing rapidly currently. As laying the high-speed railways’ track plates accurately is an important part of construction, a large number of multifunctional advanced special cranes are required in order to complete the construction task on time. In the paper, the advanced design and application of the new type large cantilever special crane, which being used in the high-speed railway track plate constructions of Jinghu railway, Huning railway and Guangshengang railway, is introduced. The special main characteristics of the new type multifunctional large cantilever are described, such as easy to be assembled, easy to change the span, the cantilever beams can being folded, can being used in the tunnel, and so on. The successful applications of the new type crane have solved a number of difficulties in the track plate constructions, and have obtained obvious economic returns and social returns.
