1. StrictLy implemente the operational procedures of tower crane , tower crane were operated by hand.we Should make Technical  and  safety training to  the drivers, maintenance staff on Assembly   and  Disassembly. Make them  understand the  Lifting equipment structure  work principles,know as operation rulesstrictly enforce the security certificates.
  2.to ensure the security protection device settings of Tower crane complete . 
   There are commonly used lifting height limiter, amplitude limiter, limiter,starting from the weight of gravity limiters.
   3. To strengthen the tower crane inspection, repair routine maintenance. 
   After years of use  and  dismantling of the tower, there is the opportunity to damage, such as cracking poor weld, if the repairs are not timely, it will endanger the safety of tower crane. Steel wire rope inspection  and  maintenance should always reach retirement standards should be replaced immediately. Insisted that professionals carry out regular inspection of tower cranes  maintenance, which can effectively prevent safety accidents.
   4. Strengthen their precautions. Wind disturbance tower crane work. With the tower crane height increase, a greater impact of wind, windy season  coastal areas, paying particular attention to.
  5. Pay Attention to the tower crane foundation design to correctly handle the security of neighboring devices. Will lead to uneven foundation soil tilting tower crane. 
   In order to prevent longitudinallateral tilt of more than provide, for the laying of track roadbed to strict requirements. In addition, we have to consider the safety of adjacent devices, such as the adjacent machine operations will affect the vibration generated when the tower crane foundation; excavator operations will change the foundation bearing capacity; apart when operating close to the tower crane may have collisions, etc..
6. Correctly assess the life of the tower crane. Now many provinces, some manufacturers of tower cranes have been forced to use is strictly prohibited, but the use of tower cranes do not have uniform retirement age standards, recommended relevant departments to develop standards for tower cranes scrapped, to determined retirement age.
7. Make technical preparations for lifting operations, risk analysistechnical tests, to ensure the successful completion of large-scale hoisting an important part of the security.
   First of all, they must be carefully calculatedtechnical feasibility studies to develop practicaltechnical programs; Secondly, we must conduct a risk analysisthe lifting process of lifting  disassembly operations riskshow to preventavoid accidents;
thirdly, fully operational before relevant personnel to participate in operations conducted technical tests, a clear division of responsibilities, implementation of safety measures,operating all the preparatory work for an inspection;
fourthly, the operating process, we need to strengthen  construction hoist safety monitoring.
