installation and disassembly of tower craneBuilding construction site, to address the construction phase of the vertical transportation, speed up the construction
schedule, and improve the operation of the level of mechanization of modern construction, according to the actual situation
in the construction site, generally in the middle or the side of the building installed a number of stationary tower crane
(hereinafter referred to as tower crane) . A set of standard tower crane installation, disassembly and operation of technical security tests, be critical and must
be caused by the project department technical staff are highly valued. In this paper, reality, talk about the actual work to
install, demolition and operation of technical safety tests, be processes and content. 1 shows that this is installed as a normal transition (or new purchase) installation, the installation process should be
strictly in accordance with the installation and removal programs, and shall not be altered arbitrarily. , 2, the installation sequence of chassis (with Level Leveler) ¡ú Standards ¡ú Festival ¡ú coat rack tower slewing

the top of the tower the root of a) ¡ú arm ¡ú balanced tower block ¡ú balance arm ¡ú ¡ú ¡ú Cab ¡ú slewing mechanism and
standard sets of planes at the end of Day ¡ú frame. 4, safety measures, installation (removal) operations before the person in charge of organizational learning by the general
installation of the safety technical requirements for all operations personnel in technical tests, daily work content of the
sub-tests, be one by one: enter the job site must bring helmets, high-altitude operating hours to wear seatbelts, wearing
non-slip shoes; case of overhead transmission lines should pay attention to keep a safe distance; top of the wind speed is
greater than 13 m / s prohibition of operations; sets of planes, the upper and lower bearings, front and rear lifting arm
and other equipment operation before the need for special technical director of security technology correspondent, each time
hanging about 20 cm from the ground must be shut down, check the security of more stable, secure and reliable confirmation
can only continue lifting; long, large object hanging points should be accurate to ensure the crane material balance,
lifting pre-application of a solid rope tied firmly to both ends to prevent the heavy rotation, swing and collision; install
the operating 5 ~ 10 meter zone should be located within the security cordon, to send someone to guard the construction
site, non-operational staff shall enter the warning line . 5, the installation removal considerations
