Overall Layout of HZY900t Girder Transporter
HZY900 girder transporter is composed of car-frame, sleeper beam, hydraulic suspension, dynamic system,hydraulic system, electric system, control system, braking system, steering system, cab and other parts.HZY900 girder transporter has reared engine, main beam of car-frame in the middle, 2 tandems and 16 axis in total.There are 2 wheels for each axle, 64 wheels in total. It adopts 5.5-axis drive, 22 wheels in total. 26.5R25 tubeless pneumatic tyres enlarge ground-connection area, so that the ground-connection pressure will decrease as soon as possible. Main hydraulic components, such as hydraulic suspension, hydraulic drive, hydraulic brake and hydraulic steering system, use imported international famous brands.Control system adopts FCS (Field Bus Control System). There are the same configuration for cabins in the front and back and main electronic components are imported from Finland.
During transport period, concrete precast box girder must prevent from torsion. Hydraulic suspension system of the girder transporter is in connection in group, there exists three-points bearing method in isosceles triangle shape and box girder as symmetric section. As long as the operator can make sure that the geometric center is unanimous with the center of girder transporter, there will not exist torque in axle direction.
When feeding girder, the bearing will change from statically-defined three point into hyperstatic multi points, which enlarge the bearing stability and decrease the bending moment of main girder of car-frame. Meanwhile, because it changes the situation in still, the support reaction will not have any variation and the stress status of the box girder will be kept.
