Products HZQ series rail-cum-bridge machine is a box-shaped double-beam bridge machine, it is to draw from the characteristics of various types of foreign and successful experience erecting machine factory highway bridge machine, according to a small part of the railway roadbed construction , bridge and tunnel more closely linked to the characteristics of bridges and tunnels, according to "Crane Design Manual", "Crane Safety Regulations Handbook" "rack railway bridge girder Manual" and other relevant technical information standards and requirements. My company and the construction unit after careful study carefully investigate repeated several times to modify the design plan, design and manufacture of the new bridge machine. Main Features 1 height is low, but the machine can pass through the tunnel, the beam can be fed in the tunnel. 2 pieces of weight does not exceed the maximum 7.1t, length does not exceed 10m, to meet the automotive requirements of gauge cargo transportation boundaries. 3 additional auxiliary trolley and flip gantry, function relatively complete, and can be bi-girder, and can track laying. Partially modified, replacing some components can be erected highway beams. 4 comes with power, can be a greater distance traveling on the railway tracks. 5 models of small, disassembly, and easy maintenance. Train transport transitions just part of the Union, without cranes, gantry with flip disassemble can.
