Tower crane in the installation before there is a certain amount of preparation, only the preparation in place, to ensure the normal follow-up installation, and the tower crane in the installation before what preparation to do well? Today's small series here for you to carry out the following finishing, I hope you can help us on the tower crane installation knowledge has a more in-depth understanding. Tower Crane installation preparation work: 1, Tower Crane Foundation Inspection: Check Tower Foundation concrete pressure test report, until the design strength of concrete can be organized tower crane installation. The horizontal error of the upper surface of the concrete tower foundation is not more than 0.5 mm. The concrete tower base should be 150mm higher than the natural ground, and have good drainage measures, strictly prohibit the tower base water. 2. Check every parts of the tower crane, such as structure welding seam, Bolt, pin shaft, guide wheel, steel wire rope, Hook, hanger, hydraulic climbing system and electric equipment, and solve the problems in time. Check the tower crane switch box and power supply line to ensure safe power supply during operation. Check whether the technical performance of the installation and use machine is good, check whether the installation and use of safety protection products meet the requirements, and solve the problems immediately, to ensure the safety of the equipment and safety protective equipment used in the installation process. 4, the tower crane in the installation process must be kept clean and orderly, so as not to hinder the work affect safety. Set up the work area cordon, and set a special person responsible for vigilance, to prevent the tower crane installation of unrelated people into the tower crane installation site. 5, tower crane installation must be carried out during the day, and should avoid rain, wind, fog weather, such as in the operation of sudden changes in weather to stop the operation. 6, to participate in the tower crane installation and demolition personnel, must be specially trained by the Labor Department, after passing the examination and holding a license to post. Tower Crane installation personnel must wear a hard hat, high-altitude workers to fasten the seat belt, wear anti-slip shoes and work clothes, work to unified command, action coordination, to prevent accidents. Anti-collision measures for tower crane operation. The minimum erection distance between the tower and the tower should ensure that the distance between the end of the lower tower crane arm and the tower body of the other tower crane is not less than 2 meters, and that the tower crane at the higher level (the hook rises to the highest point) and the tower crane at the lower level, in any case, the spacing in the vertical direction shall not be less than 2 metres. Only after the above safety inspection is completed can the normal collocation of the follow-up tower crane be ensured, the safety performance of the follow-up tower crane in the use process be guaranteed, and the normal development of the project be ensured.
