China HSHCL mtr launching gantry girder erection crane equipment

Product Description

China HSHCL mtr launching gantry girder erection crane equipment for bridge construction is generally used in the erection of the Highway Bridge and Subway Bridge, using the precast segmental pre-stress concrete box beam (PC beam) assembly.

The main feature of mtr launching gantry girder erection crane equipment is the high efficiency of construction and self-traveling. Generally it is composed of the main beam, leg and winch trolley, the main girder is used for bearing, the leg is to execute machine transverse moving, longitudinal moving, leveling, support, cross span, cross scale and other functions, and the winch trolley used for lifting the precast girder.

3.What are inspection standard for load test of China HSHCL mtr launching gantry girder erection crane equipment?

a. Dynamic load test

1.1 times rated load, main girder does not down deflection, all mechanisms work well, performance parameters meet the design demand, all limit switches and safety protection interlock devices are reliable, all spare parts does not have cracking and flexible connection, all motors and contactors are not overhead.

b. Static load test

1.*5times rated load, all mechanisms work well, the crane stops *0min to *0min as trial load is lifted *0cm high, then measure main girder down deflection(theodolite, ruler). Put down trial load to measure main girder upper camber, repeat 3 times, steel structure does not have permanent deformation.
