current tower crane and other construction machinery maintenance problems, the people concerned attach importance to the maintenance of the tower crane, but neglect it. They think that the tower crane is a waste of time and affects the progress of the project. It is also expensive and laborious Do not engage in maintenance within a certain period of time will not appear much problem, even if there is a failure to repair the unit, the problem will be solved. Usually speaking of the prevention of mechanical safety accidents, speaking of the prevention of mechanical failure less. It is very important to do well the check and maintenance of tower crane. Some units in the use of the process, the inspection of the maintenance of the non-maintenance, small failure regardless, only do not maintain, until the tower crane can not work, think of the lack of maintenance. In fact, the functions of mechanical maintenance and repair are separate. If the machinery is not maintained in use, its technical performance will be reduced, and failure will definitely occur if it is not maintained for a long time But the role of maintenance and mechanical performance decline, failure is not immediately reflected, there is a longer process, easy to be misunderstood, ignored. .

Many users of the legal management awareness is weak, not in accordance with the mechanical maintenance system for tower crane maintenance, especially the use of their own day-to-day maintenance and other low-level maintenance plan is not implemented. It is considered that the technical condition of tower crane is mainly decided by the repair unit, and that the repair unit has not kept pace with the repair force because the tower crane can not operate. Some users and machinery management departments, once encountering engineering tension or field conditions, do not strictly implement the maintenance provisions of the tower crane, not in accordance with the quantity and quality of maintenance provisions. There are also some units to simplify the rich content of maintenance tower crane, heavy tower crane appearance scrub, clean, light machinery internal inspection, maintenance. In order to cope with the superior inspection and evaluation, on the Organization of personnel temporary raids, tower crane cleaning as the main maintenance content, beautiful appearance, the actual YTHT, tower crane maintenance of various registration centralized fill, play word play. Even some units lack the necessary tower crane maintenance tools, accessories and consumables. They are reluctant to buy tools, spare parts, or even to buy oil for maintenance. As a result, a small amount of money was saved and a large amount of money was spent on the maintenance and use of machinery. The Tower Crane drivers who operate the tower crane lack the necessary knowledge of mechanical theory, and do not know much about mechanical structure, principle and performance. In general, they pay more attention to the study and training of use and operation skills And maintenance, troubleshooting skills to learn not much, do not know how to arrange, organization maintenance work; maintenance and do not know what the specific content of maintenance, make tower crane maintenance can not be implemented. The Tower Crane and other construction machinery maintenance is improper even can cause the tower crane breakdown or the safety accident. Timely, high-quality, efficient maintenance of construction machinery, such as tower crane, to extend the service life of machinery, improve the rate of machine integrity, to ensure the completion of construction and life and other tasks are very important. Secondly, there is the quality problem. Tower cranes are special equipment. The state has quite strict requirements for their manufacture and use. This requires going to the production site to inspect and see if their production techniques meet the requirements Can Be divided into three parts to examine 1. Welding Quality 2. Quality of supporting mechanism 3. The quality of the raw materials and materials can be examined with emphasis on the above three points, such as lifting mechanism, rotary mechanism, amplitude-changing mechanism, electrical system, etc. Welding and raw materials now with the management of higher authorities to basically eliminate the phenomenon of non-conformity, now some manufacturers have the idea of supporting institutions, because this area for the user less clear, it's not really a matter of quality and safety. This problem is more difficult, because some professional knowledge is layman do not understand, when purchasing better with the staff who know more about tower crane can not be cheated, once some users take the price of Qtz40 to buy a QTZ315 back, you can also seek professional personnel consultation. Again, the tower crane after-sales service, we must make clear the warranty period, warranty content, some manufacturers promise to warranty, but warranty period is not charged personnel service fees, accessories or charge. Now the tower crane warranty is basically half a year, seems to have become the tower crane industry agreed into the secular period.
