Characteristics of bridge erecting machine’s hole-passing operation:

1.Still adopt the operation mode of cantilever hole-passing, with the middle car running on four rails and the rail gauge being 2.7m;

2.Before hole-passing, the front support leg, middle support leg and rear support leg should be in the middle position (transverse middle position); install a hook between the lower crossbeam of the front support leg and the transverse beam; pull out the large steel pin on the middle of the transverse beam of the middle support leg and keep the small steel pin below the middle; the front and rear truss cars retreat to the hole-passing position, and after inspection, conduct hole-passing;

3.After the hole-passing is in place, adjust the parallelism of the transverse rails of the middle and rear cars, and control the distance error between the two ends of the transverse rails of the middle and rear cars within 1cm;

4.Jack up the lifting hydraulic cylinder of the front support leg, install the steel pin of the front support leg, install wedge-shaped spacers between the pier blocks at the two ends of the transverse beam of the front support leg and the pier, and support the front support leg well;

5.Jack up the support hydraulic cylinder of the middle car, install the large steel pin on the middle of the transverse beam; install the support block at the specified position between the platform frame and the rail, retract the hydraulic cylinder, at this time the transverse slideway is in a horizontal state, and the height difference at the two ends of the slideway should be controlled within 1cm; under the anti-tipping support pier at the end of the transverse beam of the middle car, install sleepers or square timbers, but a gap of 2-3cm must be left;

6.Dismantle the rear rail of the middle car and move it to the middle to provide space for the girder transport vehicle to transport girders.

Bridge erection machine advantages:

1.Simple support erection: Retractable flexible front legs and rigid O-shaped rear legs support the main beam at two points, forming a beam frame state of one span simple support state, with clear force;

2.Simply supported vias: The crane trolley, auxiliary crane and auxiliary outriggers cooperate with each other to make the vias of the bridge erection machine a span simply supported state, and the whole machine has greater longitudinal stability and high performance.

3.The beam body is hoisted with good stability: the two hoisting beam trolleys cooperate with each other to carry the beam three-dimensional movement, which can meet the requirements of the beam body erection. The hoisting beam body adopts four-point lifting and three-point balance, and the beam body is in good stress condition.

4.The height of the whole machine is low: the rear of the winch is separated from the crane trolley, which reduces the height of the whole machine and has a strong ability to pass the high-altitude limit.

5.It is convenient to erect the first and last span beam bodies: the high-level lower guide beam is adopted, which conveniently solves the erection of the first and last two spans of the bridge line.

6.High operating efficiency: the process of erecting and transporting beams is separated to improve the efficiency of construction operations.

7.Reliable: Lifting device is equipped with monitoring alarm, emergency braking device, limit limit device, overload protection device, winch double-stage braking, working environment wind measurement and control device.

8.Easy adjustment of variable span: auxiliary legs, front legs, etc. cooperate with each other to meet the needs of variable span adjustment of bridge erection machine.

9.Easy operation: Set up two sets of operating devices for special cab and wireless remote control, especially remote control device, which can be close to the job site, good line of sight, simple and reliable operation;

10.Equipped with beam lateral fine-tuning function, alignment error ≤ 2mm.

Working principle of the bridge erecting machine:

The bridge erecting machine is a kind of hoisting mechanical equipment that places the prefabricated beam slices (or box girder steel frames) on the prefabricated bridge piers. Because its main function is to lift the beam slices and then transport them to the position and put them down. The bridge erecting machine belongs to the category of special cranes. The bridge erecting machine is very different from the crane in the general sense. It has strict requirements and there is walking on the beam slices or longitudinal movement.
