Analysis on technical measures of collision safety for tower suspension
6, in the crossover construction, the driver should be hanging outside the cross area, the hanging object to the designated location, can change the horizontal interval.
7, during the construction of the intersection area, the two towers should rotate counterclockwise to avoid the two crosses. Tower price.
8, in the cross-zone construction, the two towers hanging objects steel wire rope should be tightened to avoid the upper tower hanging steel wire rope collision with the next forearm.
9, during the construction of the intersection area, should avoid the two towers to hang the long material objects at the same time.
When operating in the intersection area, it is forbidden to hang two towers at the same time in the intersection area at night.
It is strictly forbidden to operate without command and simultaneously while operating in the crossover area.

12, in the area of operation, in the event of wind more than four grades, should stop the large plate operation.
When the 13, 6  West Unit is hung with a large template, if the 5th Building needs to be hung with steel bars, it is necessary to negotiate with the 6th Building in advance to stagger the hanging time difference to avoid collisions.
III. Collision Risk Sources, Risk Time Analysis and Prevention:
1. Determine overlapping specific parts: 5  and 6  overlapping arms 24 meters; 5  and 8  overlapping arm 48 meters, overlapping tower 8 meters.
2. Determine the height difference when the crane arms overlap

3.5 Due to the early start of construction, the building has now been constructed to the 11th floor. During the lifting or daily use of the tower, it is higher than the three standard sections ≥ 9 meters of the 6 # tower crane. Therefore, there is no danger of collision of the upper arm. The collision risk period is 5  buildings. During the lifting of steel bars, the upper arm rotates within the radius of the 6 tower crane, and it is easy to collide the wire rope.
4.8 The construction of the  building has just started. During the basic construction phase, at the time of the installation of the tower crane, the two project managers reached a common call for the tower crane installation site and mutually agreed on the handling of the tower crane lifting area, rotary area and special circumstances.

In addition, the intercom frequencies used by the two sides are the same, but they are only in different bands. When there is mutual needs for coordination, the drivers of both sides can adjust the bands to handle the negotiations.
5. Overlapping area marking, driver visible.
6.6 The project Department of the building has 3 full-time drivers and 4 command staff. Each shift has 3 people working up and down at the same time and is under 24-hour security supervision to prevent collisions.

7. Equipped with a full number of walkie-talkies, drivers, commanders, and everyone.
8. The security officer monitors the management every day.
9. Time-lag system for overlapping areas
1) General lifting work, according to the empty car to allow heavy vehicles, that is, empty operation tower suspension to avoid hanging heavy lifting tower.
2) First come first: that is, according to the first come and then to the order of construction, special circumstances such as emergency rescue can be adjusted.
3) Call each other a siren to prevent collisions
4) Location during downtime: When the operation is temporarily stopped or work is released, the stop direction of each tower crane does not interfere with the scope of other tower crane rotation operations.
The temporary lifting of a tower in an overlapping area during non-working hours should be reported to the project department. Each project department should adjust to avoid the scope of operations.
Measures taken at the time of decommissioning:
1. the safety officer correctly grasped the weather forecast and wind direction every day. When the tower crane driver set off work, the two towers were parked in the downwind direction.

2. night duty staff, pay close attention to the change of the red flag at the front of the arm and the steering of the tower crane. Inform the security officer and the tower crane driver when you find out the situation.
3. when the wind direction changes, the tower crane driver should immediately put the tower crane arm in the downwind direction, and lower the hook, lock the wire rope and the ground fixed pile to prevent the tower crane collision due to sudden wind direction.
4. strictly prohibit the tower hanging free rotation, causing collisions.
5. in case of inspection, attached walls, top lifting operations, notify other tower hoists one day in advance to avoid collisions when the tower hoist is in the high-risk operating environment of inspection, attached walls, and top lifting operations.
