Safety operation rules of tower crane 25, welcome to consult various models price
With domestic advanced construction machinery production line, precision testing equipment, can ensure reliable quality and safety. Below, the factory according to tower crane production and use experience, summarized tower crane safety operating procedures 25.

(15) Safety protection devices, such as the barrel-variable amplitude brake, the walking limiter, the torque limiter, the hook height limiter and various stroke limiter switches of the tower crane must be complete and complete, sensitive and reliable, and must not be arbitrarily adjusted or removed. It is strictly forbidden to replace the holding mechanism with a limiting device.

(17) Tower lifting machinery must be operated according to the prescribed tower lifting function, and objects with unknown components shall not be overloaded or lifted. Under special circumstances, when overloading is required, it must be checked, there must be technical measures to ensure safety, and with the consent of the person in charge of the enterprise's technology, there must be a person in the field to supervise the lifting, but it must not exceed 10 % of the limit.
(18) It is strictly forbidden to hang heavy objects in the air for a long period of time. In case of sudden failure in operations, measures should be taken to land heavy objects in a safe place, and the motor should be closed or the power supply cut.

 In the event of a sudden power outage, all knobs should immediately be set to zero, the main power switch should be disconnected, and measures should be taken to safely lower the weight to the ground.

(20) When lifting heavy objects, they should be tied smoothly and firmly. Sporadic objects should not be piled or hung on heavy objects. Pieces of data and objects must be secured by hanging cages or wire ropes before they can be lifted. Items marked with the status or marking of the binding shall be tied according to the indicated position. The angle between the tied wire rope and the object shall not be less than 300

(21) In the event of strong winds or heavy rain, heavy snow, fog and other bad weather, the tower should be suspended from the open air operation. When working after rain and snow or in rain and snow, you should first go through the test crane to ensure that the brake is sensitive and reliable before operating.
(22) When the lifting load reaches 90 ° and above of the additional lifting weight of the tower, The weight should be lifted from the ground 20 to 50 cm to stop lifting and perform the following inspections: stability of the crane, reliability of the brake, stability of the weight, and firmness of the tying. After confirmation, it can be lifted continuously. For heavy objects that may be shaken, Shuanlasheng must be killed.
(23) The speed of promotion and descent of heavy objects must be average. It is forbidden to move quickly and suddenly. The left and right roll back action should be stable, when the turn does not stop before the reverse action. Non-gravity reduced tower crane, not allowed to carry free landing.
(24) The minimum distance from the top of the tower hook device to the bottom of the car frame: 1000mm at the upper rotary rate of 2 times, and 700MM at the 4 times rate; The downward rotation is 800mm at 2 times. The rate of 4 times is 400mm, which should be able to end the lifting immediately.
