The lifting scheme of the indoor equipment for the workshop and the outdoor equipment and aerial equipment

Selection of hoisting equipment
According to the characteristics of the equipment itself and the hoisting site, there are two kinds of hoisting vehicles for hoisting engineering..
One kind is the automobile crane, the crane is suitable for outdoor work, the advantages of truck crane is transferred rapidly, flexible, high lifting height, lifting must be landing on the legs, can't load running and in the workplace require a higher, space height and the surrounding space was greater than 10 m ground must be smooth, compaction, so as to ensure the stability and safety in operation.
A lorry crane, crane suitable for indoor and outdoor operation, lorry crane working principle of hydraulic control system, installed on the truck compartment of a new crane. Its advantages are flexible and operation requirements for space and space height and the surrounding space was greater than 6 meters on the line, the most suitable for work in the factory (workshop), weight, and smooth comes with the loading of the goods, lifting operations of the effective working range wide, manufacturers and enterprises handling equipment, relocation, lifting the ideal construction of a lifting equipment.
Two. The determination of lifting method and technical measures
1, construction method of determination
According to the actual lifting equipment body parameters, structure features and construction site conditions, using different hoisting equipment and method, generally high-rise equipment of lifting the automobile hoist, for low layer mechanical hoisting equipment, using a truck crane hoisting, large can use two truck crane with each other auxiliary hoisting.
2), equipment hanging point determination and hanging ear selection and installation
Body equipment lifting equipment lifting lugs can be used its own lug, body equipment installation lug in accordance with the requirements of hoisting equipment at the scene, in accordance with the relevant norms of choice making equipment installation of hanging ear. When the production of the hanging ear should choose the material which is consistent with the main body, and do the inspection work of the material.
3), crane design verification and rigging selection calculation
Hoisting equipment before, we must first of weight lifting equipment, structure of careful analysis calculation, reasonable design of crane location, select the appropriate lifting machinery and rigging. In rigging selection, through specific calculation formula, control various types of steel wire rope, and the allowable stress, determined to settle down. In the calculation, the disassembly coefficient, the imbalance coefficient, the dynamic load factor and the safety factor are considered..
Three, [equipment lifting company, hoisting equipment hoisting, hoisting of precision equipment] hoisting procedure
1), the approach of the facility
In the full preparation of the work, the organization of the approach and the hoisting of the equipment.
2), before lifting the preparatory work
Before the hoisting equipment, must do a thorough and careful inspection and verification of the work. Check the equipment installation datum mark, the marking whether the marking is correct, the crane ear whether the equipment is accord with hoisting requirement.
3, the selection of hoisting rigging
In rigging selection, through specific calculation formula, control various types of steel wire rope, and the allowable stress, determined to settle down.
4, test hanging
Try hanging before the examination, confirm the total lifting of command for hoisting operation disclosure, arrangement of the supervisory positions are key points and the main contents of supervision, lifting down several tests, so that each part is provided with a coordinated and safe, the review of various parts of the changes.
5, hoisting position
From the total command formally ordered to check the posts to the standby situation, and check the command signal system is normal, each position report preparation, and signal to the command station in time.
Four, note
1. Hoisting operation system and commander is the main core of equipment hoisting and the key of hoisting.. Therefore, lifting operator and commander to cooperate closely, the reasonable coordination of the two will become the perfect and efficient operating system for lifting, implement set machine, people, posts and responsibilities, in the whole hoisting process methodically carried out smoothly.
2) during the operation, the coordination of the whole coordination and operation coordination of the hoisting is coordinated to ensure the continuity and stability of the lifting process..
3), the construction site of the crane when strictly enforced "do not hang ten," the principle, namely "weight unknown crane, eat the earth not hanging, a signal is not clear do not hang, have not fallen crane, hanging objects not hanging, no lighting at night is not suspended, sling is not in conformity with the provisions not hanging, hanging objects tied tie is not firmly not hanging, hanging objects have not hanging, six more than the wind is not suspended."
