How about trial lifting and maintenance on HZQ highway launching girder?
Before HZQ highway launching girder lifts precast girder formally, trail lifting and maintenance have to be done. Indexes for trail lifting shall be clear, such as deflection, skewing, centre line and others; meanwhile results for trail lifting must be explicit (whether it meets the demands of design).

How about anchoring of launching gantry?
Anchoring refers to safe use of launching gantry, and we must pay more attention. Anchoring and wind resistance measures supplement and coordinate with each other.
How about test run of HZP1600 segmental assembly launching gantry?
After completing installation of the HZP1600 segmental assembly launching gantry, a test run is needed, which mainly include two parts: functional test and load test.
Functional test includes expected motions of support legs, motions of overhead gantry crane and trolley.
Load test includes static and dynamic load test of overhead gantry crane, load test of the complete machine.
