1. The load capacity and technical performance of the beam truck should meet the requirements of beam and plate transportation. Have a factory certificate. Before the beam is transported, the beam truck should be inspected comprehensively. The beam and slab should be bundled firmly to avoid overturning the beam slab. When the bundle is loose, it must be immediately stopped and reinforced.
2. The operator must be familiar with the structure of the beam truck, the lifting beam, the frame beam and various technical parameters. Before starting work, it is necessary to do all kinds of inspection work, such as: road clearing, electromechanical, running parts, special inspection of hydraulic system, structural connection, communication, signal, hook, wire rope, inspection of the bearing capacity of the underground of the crane. All inspections can be carried out through the rear.
3. Before loading the beam, it is necessary to check the walking road, remove and harden the road teeth at the door of the beam field, and lay the steel plate on the water channel. All the duty and staff members wear the traffic reflective vest. And should carefully check the appearance of the finished box girder, beam length, number, etc., and check the rear can be hoisted.
4. Before starting the beam truck, check the support and support of the box girder and check the direction and braking of the beam truck. Check if the safety triangle wedge under the joist table wheel of the conveyor truck is plugged.
5. The box girder should control the elevation of the four fulcrums of the beam body to remain in the same plane during transportation. The elevation of any fulcrum shall not exceed 2 mm from the other three-point plane.
6. When transporting the beam of the vehicle beam to the beam field, personnel should be arranged to block the Gaoxin Avenue. There should be red flags and brand signs before and after the beam. And there is a special person command, the commander should wear a reflective vest.
7. In the downhill direction, the beam should be provided with a slippery wooden wedge, and a special person should be responsible to prevent the beam from moving.
8. Set up special contact between the two transport trucks, keep the communication link unblocked, calculate the time of the car, and prevent the beam truck from meeting the meeting point.
9. When the beam truck meets at the meeting point, a special person will be given to conduct the command to prevent the beam truck from hitting and hanging to ensure the safety of the vehicle.
10. During the entire beam-moving process, special personnel should guide and observe the road surface changes and the entry and exit of vehicle personnel on both sides of the transport beam to prevent sudden changes. The operators should also concentrate on the work, pay close attention to the situation of the road beam truck and the roads, vehicles and personnel ahead, find abnormalities, take appropriate measures as soon as possible, and non-emergency situations, prohibit high-end emergency stop.
11. When the beam truck is driving on the curve or turning around, the speed should be slowed down to prevent the box beam from shifting on the beam truck due to the centrifugal action.
12. Under the harsh conditions such as rain, snow and strong winds, no beaming operations are allowed. Wet, slippery and frozen road surfaces should be protected to reduce the speed of the beam.
13. When the front end of the beam approaches the tail of the bridge machine, it should be decelerated in advance and fed at a slow speed. If necessary, click on the counter position, and it is strictly forbidden to collide or hit any part of the bridge machine.
14. The key point is the safety of mobile personnel and vehicles when transporting beams across Gaoxin Avenue. Before the transportation, do all the preparatory work, block the isolation channel, and hang the police line. Do a good job in traffic diversion; organize evacuation, evacuation, personnel and materials in dangerous areas; strictly control the entry and exit of personnel and vehicles, prevent and stop all kinds of activities that are not conducive to social stability, when the situation occurs, first report to the team leader, the team handles Can't report to the project manager.
