Tower crane simultaneous operation of multiple security measures

Simultaneous operation of multiple signal tower and the tower unit commanding officers should be relatively fixed, no special reason tower cranes are not free to replace the commander: commander without the consent of the competent and responsible, not unauthorized changing of the guard. Strict implementation of the process command signal commanding officers and the tower crane driver response system, that action command signal issued by commanding officers, the first call number is tower machine, tower crane driver response until after the commanding officer may give a signal tower crane movements instruction.

Commanding officer must always be visual signal tower crane hook and the hoist. Mechanism of the process of tower arm, commanding officers have to look around the signal tower adjacent to the working state, and issued safety instructions language. Safety instructions language must be clear, brief, clear and complete. Tower crane suspended work long hours, the highest point of the hook should be played, and the car pulled the nearest point lifted the sling hook, big arm to a parked by the wind. Tower crane and command staff must be equipped with radio signals, radio frequencies must be determined by the unity of locking, frequency of use of personnel not be transferred, and to do special plane. Technical measures should be reasonable arrangements to use units progress to ensure that the interference range of the rotary tower crane in lifting Canada to maintain a sufficient section of the height difference. Should be "on the fast not to slow" principle, according to the progress of unification to determine lifting tower height and position time. The tower crane must be the correct height, the time schedule to complete the top up, not in advance or delay. At the construction site layout and preparation of tower crane to install the program should be fully considered safe distance over machine operation requirements, so that the plane between the horizontal or vertical direction to maintain adequate safe distance, "when the same construction site when there are two or more cranes, should be maintained between the two aircraft nearly any location (including the hanging weight) distance not less than 2m. more machines running at the same time the principle of light rail vehicles to operate heavy vehicles in the two-tower run time, no aircraft shall give way set Horta Horta machine-load . off the main tower to tower to the actual work of different units of the regional division of crane working area, if the tower crane arm into the work area to this unit, the passenger area of the tower to make the main area of the tower crane. enforcement priority in the former out the principle that when there are a number, press the order of priority in the former. low-high tower to the height of the lower tower crane, the transfer arm should be observed before the high tower high tower crane operation after operation . After the first tower to tower crane tower arm in two cross-region runs, entered the tower confidential avoid the region first tower crane into the region. Fixed tower to tower static tower crane tower arm in two cross-case running When, in a non-slewing tower cranes, luffing and other actions, the other for rotation or amplitude of the tower crane should carry out avoidance. organizational measures to secure the construction project should be organized for people related to multi-machine operations personnel, such as construction scheduling Members, tower crane operators, tower crane Division hearing officer accordingly pre-job training and job security before the technical disclosure.
