What are details of moving system of HZQY900T launching gantry?
HZQY900T launching gantry is driven by 28 driving wheels (14 sets, 2 for 1 set) for rear vehicle and front vehicle, the driving power device is of a built-in hydraulic motor connected with wheel hubs of all driving wheels by speed reduction gearbox. Hydraulic driving motor is of variable piston motor connected with gear reducer by same shaft. Reduction gearbox has brake device.
Parking brake is of normally closed type brake which could ensure a higher brake safety as the motor misses and the complete machine is located on the ramp. All driving motors are in parallel oil supply to ensure a same output torque.
Safety operation rules for launching gantry
In the bridge construction, safety operation rules shall always come first for personnel safety and smooth operation.
How about support legs of walking type launching gantry?
walking type launching gantry for highway bridge construction has 4 support legs in total.
Special points for HZQ40/100 honeycomb girder launching gantry
HZQ40/100 honeycomb girder launching gantry is developed to install pre-cast girder bridge, it can construct bridge in below range:
How about the lifting trolley of launching gantry?
Lifting trolley is made up of longitudinal moving gearbox, transverse girder and rail, transverse moving trolley, winch, movable and fixed pulley group, and hanging beam.
How to construct a skew bridge?
A skew bridge refers that a bridge longitudinal direction axis is not vertical to crossed river flow direction or route axis. The skew bridge is often seen in intersections of two highways or more.
How to construct upslope bridges and downslope bridges for a launching gantry?
As the launching gantry construct the bridge, we usually meet a lot of different working conditions like longitudinal slope. In this case, we have to adjust height of support legs to create a suitable construction environment.
I will take an example that how to construct a bridge with max longitudinal slope 5% which usually is the max gradient the launching gantry could be used.
