Seven Principles for Ensuring the Safe Operation of Self-lifting Tower crane
The self-ascending tower crane, also known as the inner climbing tower crane, refers to the tower crane that relies on its own special device to increase and reduce the tower crane standard festival(ie, the attached tower crane) or the overall climb. Because of the adjustable height of the crane, it often has the flexible advantage that other towers can not be reached when multiple buildings are constructed at the same time.
For the majority of tower crane drivers, in addition to the general driving technology, safety production procedures are also very important. To this end, the following seven major disciplines have been summarized, hoping to help friends who are fortunate enough to drive self-propelled towers:
First, when lifting the member, the balance weight according to the prescribed weight is moved to the specified position before lifting.
The concrete strength and reinforcement of the attached or fixed tower foundation and the attached building must meet the design requirements.
Third, the cable must be relaxed before the top rise. The length of the cable must be slightly larger than the total top rise height, and the cable reel must be tightened.
Fourth, the special elevator is prohibited from overtaking people. When the arm rod is rotated or lifted, it is forbidden to lift the elevator. After use, it must be lowered to the nearest position on the ground. It is not allowed to stop in the air for a long time.
Fifth, in the lifting process of this type of tower, the rotary part should be braked, and the rotary tower cap should be strictly prohibited. When the top is lifted, the fault must be found. It must be stopped immediately for inspection. After the failure is resolved, the top can continue to rise.
Sixth, when the top rise, there must be a special person to supervise the power supply, control the hydraulic system and fastening bolts. Non-workers are prohibited from boarding the top lift platform, and they are not allowed to arbitrarily press the switch or other electrical equipment. It is forbidden to carry out the top lift at night. work. Those above level 4 are not allowed to carry out overhead work.
Seventh, after the lifting of the ceiling of the self-ascending tower, it is necessary to check whether each connection bolt is secured, whether the climbing sleeve roller is in good agreement with the standard section of the tower body, whether the left and right joysticks are returned to the middle position, and whether the power supply of the hydraulic ceiling mechanism is cut off.
