Deck crane is a special equipment dedicated to the cantilever assembly and installation of bridge prefabricated segments. It features hoisting, luffing and traversing functions, allowing for the accurate positioning and installation of prefabricated segments. It is widely used in the symmetrical cantilever assembly construction of long-span bridges.

Welcome to inquire for designing, fabricating and commission non-standard big-scale construction machinery. If need any solution of derrick crane, please kindly inform the following informaiton.

Project Basic Information

Component type and maximum weight per unit（Concrete beam， steel box girder or steel truss )

Cross-sectional dimensions and lifting point drawings of the component

Maximum lifting capacity and lifting radius

Maximum lifting height or lifting depth

Number of cranes required for integral construction(single unit or multiple units)

Transverse slope and Longitudinal slope data of the bridge

Permissible positions, dimensions or drawings of fulcrums and anchorage points

Is the luffing function required? (During the process of the boom from the minimum angle to the maximum angle, what is the maximum distance between the hook and the center line of the boom’s lower hinge point?)

Is the slewing function required? (The upper structure of the crane can rotate 360 degrees or 100 degrees to the left and right.)
