However, in the jungle so many crane operations, there are still a large number of crane belongs to the ultra-service phenomenon, which also brings great risks to construction safety.

    In fact, national and industry-related regulations have already pointed out many times, before and after installation and tower cranes in daily use should it be checked. Every weld metal structure can not be cracked, the metal structure can not be plastically deformed connecting bolt, pin quality to meet the requirements, the only retreat, locking measures, connecting bolt preload to regularly scheduled staff, wire rope lubrication and maintenance is good, broken wires may not be exceeded never allow off shares can not be plastically deformed joints Shengka standard, gearbox and fuel tanks must not leak, the hydraulic system pressure is normal, brake and limit the insurance sensitive and reliable transmission mechanism oiled, complete and reliable safety device, the electrical control circuit insulation is good. In particular, to supervise the tower crane drivers, maintenance electrician and mechanical maintenance man should always check inspection should focus on the vulnerability of the rope, hook, each transmission parts, limiting safety devices, found the problem dealt with immediately, so be people, fixed time, fixed measures to strictly prevent mechanical work sick.
    When crane time more than a decade, should inform the technical appraisal units identified by the use of units, if not to ensure the safety, then it should be done in scrap.
