Gantry Crane for Shield is a heavy lifting equipment designed for slag discharge, equipment transportation and shield supporting operations in subway tunnel construction. It can automatically complete the slag discharge, slag dumping and circulation operations to meet the material transportation needs of tunnel construction. In addition to slag discharge and unloading functions, the crane can also be used for tunnel tube sheet lifting, shield set assembly and other key operations, is an indispensable and important equipment in shield construction.
Gantry Crane for Shields are mainly divided into four series according to the lifting capacity and applicable tool diameter, which can meet diversified construction needs:
100-ton series: lifting capacity of 100 tons, applicable to the installation of shield structure tools with a diameter of 6.3 meters and below.
200 tons series: 200 tons lifting capacity, suitable for 13 m diameter shield tool installation.
130 tons series: lifting capacity of 130 tons, mainly used for medium-sized shield cutter and pipe sheet lifting.
100 tons series: lifting capacity of 100 tons, applicable to the diameter of 6.3 meters and below the installation of shield cutting tools.
The upper spreader of the shield gantry crane can be swung to adapt to the needs of excavation in different directions. For the special characteristics of shield construction, the spreader adopts special design, equipped with adjustable clamps or hooks, adapting to different sizes and weights, and is able to firmly grasp irregularly shaped heavy parts such as cutter plate, shield body and pipe sheet.
