1, group tower operations, between the tower and the tower height of 5m must be maintained above a safe distance.
2, operation, check the on-site environment, to ensure safe working distance and a variety of security conditions.
3, the operation must be checked before the limiter, safety devices are flexible and reliable. The wear of rope, with or without injury, whether you want to replace. Begin operation, the first whistle to alert, to draw attention.
4, the driver in the operation according to the signal given by the command signal, semaphore, gestures to operate, before the whistle to indicate operation. Found unclear or command signal has mistakenly caused the accident, the driver the right to refuse and to take measures to prevent accidents.
5, the base operations tower, the tower and the tower must be maintained between the height of 5m above the adequate safe distance, keeping low and high tower boom Tata body over a distance of 5m.
6, plus low-rise tower section, the tower to stop. High-rise tower, the tower shall not be lower in high-rise tower within the operation.
7, the tower crane hook and amplitude must be disabled car received the required position.
8, the construction must have sufficient night lighting, warning lights should be on the tower crane.
9, group tower operating principles:
Low tower to tower: the arm should be preceded by a low tower observation tower in the operation further operations.
After the first tower to tower: tower crane tower arm in two cross-zone operation, entered the region avoid the first tower crane tower crane into the region.
Run the tower so quiet tower: tower crane tower arm in two cross-regional operation, the operation of the tower crane should give way to a stationary state of the tower crane.
Light rail vehicles to heavy trucks: two tower crane at the same time running, no-load Heta machine should take the initiative to avoid load Heta machine, tower crane in the arm, the non-adjacent sites simultaneously in the same tower crane lifting operations.
10 tower cranes operating conditions shall be in accordance with relevant standards, a reasonable choice of sling. Is prohibited or different models of different types of rigging together to use.
11, are not allowed to pull heavy objects with the hook hanging directly, must be rigging or special equipment.
12, slender fugitive items, to bundle two or more, and have two hanging points; in the process of lifting, lifting objects to maintain the level of allowed deflection, or vibration so as to avoid heavy weight such as reason for removing them from the bundle in an accident. Lifting Sansui items, use the net, basket or other container dressed, not tied with a rope. Lifting bulky or long objects, the object should be suspended at both ends of a rope to prevent the swinging of the slip.
13, operating according to regulations. Starting from the zero point only by file operations, file operations more strictly prohibited. Mass transport in the direction changing device operation, the first controller, pull back to zero until the drive is stopped and then reversed, changing the direction of rotation directly is strictly prohibited. Operation to be smooth.
14, hook lifting height and the distance between the boom head at least shall not be less than 1m. Lifting heavy pan, the height of the leap from the height of not less than 1m. Luffing boom crane for hoisting heavy tone arm against amplitude.
15, crane downtime, rest or relax when half-way power brake, remove the weight, not the weight hanging in the air.
16, the driver operating room during the winter to take security measures to prevent fire, electric shock accident.
17, lifting the stick to the "do not hang ten" requirement: ① not allowed to lift command signal is unknown. ② stayed inclined not allowed to hang. ③ hoist overload weight unknown or not allowed to hang. ④ bulk material loading strapping material is not strong or at least not allowed to miss hanging. ⑤ hoist was not allowed to hang on. ⑥ buried objects are not allowed to hang. ⑦ safety device failure or sick are not allowed to hang. ⑧ not see the dark spot light hanging objects are not allowed to lift landing point. ⑨ edge blade material in direct contact with the rope hanging without protection measures are not allowed. ⑩ six or more strong winds are not allowed to hang.
18, six more strong winds and wet weather prohibited operations. Crane to be done when the storm special treatment.
19, prohibited the use of cranes lifting personnel. Do not drink and operate. Non-heavy free-fall, when the weight fell about 1m away from the place at the point, it must use a slow place. In the heavy lifting or hanging down, in the bottom of hanging objects and not people stop walking.
20, is strictly prohibited in the operation of crane repair, adjustment and maintenance operations, in addition to checking the necessary circumstances are not allowed to live. Drivers must be up and down the ladder, and are not allowed to carry heavy objects. After the end of operation when the tower crane, crane parked in the driver should not prevent rotation of the position. Any organization with a rotary brake or normally closed brake crane, after the cessation of operation, the driver must release the brake, the absolute prohibition of restrictions boom wind rotation.
21, the boom luffing jib crane to put the most significant position of the crane trolley car to the instructions provided for open positions, and rise to the highest point of the hook, hook on the hanging weight is strictly prohibited .
22, the driver before work, the hook must be raised to higher than 3m above the highest obstacle, after work to pull the controller back to zero, turn brake relax, cut off the indoor power supply, make shift recording, shut all doors and windows and locking down the tower, and then cut off the supply of main power switch.
