1. Mobilization and upper arrangement of equipment: the mobilization, upper arrangement and hoisting of equipment will be started when all preparatory operations are completed.
2. Preparations before hoisting: it is necessary to conduct comprehensive and careful inspection and verification of equipment before hoisting. Check whether the equipment datum symbol and azimuth line symbol are accurate; Check whether the lifting lugs of the equipment meet the lifting requirements.
3. Coupling of hoisting rigging: mainly including the lifting lug of the pulley, the tension test and orientation adjustment of the electric winch, the setting of towing and tailing systems, etc.
4. Trial lifting: Huai'an equipment displacement The company needs to remind everyone here that they must check before the trial lifting; The chief commander of hoisting shall conduct hoisting operation disclosure; The key and primary contents of each supervision post for supervision; Lifting and lowering for repeated tests to ensure coordination and safety of all parts; Recheck the changes of each part.
5. Hoisting in place: the commander in chief formally orders each deputy commander to check the readiness of each post and check whether each command signal system is normal; Each post shall report the preparation and inform the command console by signal in time; When the formal lifting makes the equipment break away from the temporary support by 500-800mm, stop and further check whether the situation reported by each post is normal; Withdraw the equipment support and sundries on the ground to continue lifting
The following requirements are necessary for the use of hoisting
(1) The thickness of the roll bar for handling mobile equipment with tumbling method used in soil method construction shall be 50cm longer than the width of the pallet in the same year. It is strictly prohibited to fill the roll bar with gloves. When loading and unloading vehicles, the slope of the beading shall not be greater than 20 °. The erection of the raceway shall be flat, and the rolling speed of the staggered solid joints shall not be too fast. If necessary, the sliding rope shall be used.
(2) If any problem is found during the equipment process, it shall be handled in a timely manner before continuous lifting.
(3) When lifting large tower equipment with derrick mast, it is necessary for multiple winches to operate jointly. The winch speed of each winch is roughly the same. It is necessary to ensure that the force on each lifting point on the tower body tends to be uniform to avoid deformation caused by uneven force on the tower body.
(4) When using the slewing method or the overturning method for large hoisting, it is necessary for the hinged wrist of the equipment at the bottom of the tower body to resist the horizontal thrust generated in the hoisting process to arrange the sliding rope of the tower body in the hoisting process. It is necessary to ensure that the tower body gradually falls into the foundation to avoid accidents and deformation when the tower body rotates in place.
(5) The strength and stability of equipment on the scaffold or building shall meet the requirements of equipment conditions. After the equipment and equipment are positioned, the lifting shall be connected and fastened according to the requirements of the drawings or welded to meet the strength and stability requirements of the design before uncoupling; otherwise, it shall be temporarily fixed
Operating characteristics and parameters of lifting belt
1. It is especially suitable for lifting belts of circular objects.
2. The outer surface of the lifting belt is precise and will not cause damage to vulnerable objects.
3. There are many methods of lifting belt, which can also be used to postpone the hoisted object.
4. The average force on the lifting belt extends the operating life of the lifting belt.
5. The hoisting strength component ratio is high.
6. Wear resistant and anti blocking protective sleeve can be added.
7. A common label is provided, and the world standard color is used to distinguish the carrying tonnage, which is easy to identify even if the sling is worn.
8. Simple and soft, easy to use in narrow space.
9. Non conductive, no contact risk.
10. The hoisting shall comply with European standard EN1482-1:2000 and Chinese industry standard GB/T8521-1997.
