Bridge and road maintenance machine HZQ
 
 
    Central Construction Machinery production HZQ road bridge machine to its instruction manual, highlighted before the formal lifting equipment, lifting first trial, the test must also be overloaded. General industry standard for lifting in excess of 30% is appropriate, but the crane hoisting large tonnage, by design, technology, materials and machines involved in the security sector overload agreed amount, but must overload test must be carried out. Several indicators try hanging checks must be clear, such as deflection, roll, midline; the same result must explicitly try hanging the finished (and whether it meets the design requirements.
    After the airplane and all lifting equipment installation is completed according to the requirements of design drawings, first project organized by the Ministry of erecting machine and lifting equipment to conduct a comprehensive and detailed examination; the final quality inspection department inspection, who found deficiencies must be promptly reinforcement or rework, after acceptance, in order to carry out the test crane and lifting operations and lifting equipment inspection tables fill archive file as a machine a biography.
    Girder bridge machine metal structure is the main force structure, proper maintenance of the bridge machine is directly related to the bridge machine performance, safety and life, therefore, the use of maintenance is also very important.
    1. Check the machine each girder bridge connecting welds found cracks should stop using, implementing re-welding.
    2. When they find the main beam or girder residual deformation instability phenomenon, should immediately stop using, and dealt with as appropriate.
    3. Take the regular maintenance of painting to prevent the corrosion of metal structures.
    4. Must avoid abrupt starts, braking, playing the anti-car.
