Tower Hoist equipment installation and removal

Tower  Hoist equipment  installation and removal
A preparation before disassembly
Assembly and disassembly of electric hoist tower is the central part of the construction, a great danger, must be fully prepared before construction: ① technician should be based on the construction of the installation manual and the specific characteristics of well construction programs or construction design, and has a safety technical disclosure of the content. Construction program must be communicated to all the pre-job construction personnel, avoid going through the motions; ② construction program response key and difficult parts of the assembly and disassembly method of calculation and discussed in detail, with clear construction methods, choosing the right  Wire rope winch ，  slings , hanging points, tying methods.
2 assembly and disassembly operations
Banner Engineering process must be done unify thinking, unified command, the safe use of procedures by the construction. Should be noted: ① construction  wire rope winch  pull the legs should be playing on firm ground, mat or square wooden planks necessary; ② oblique hanging, side crane, lifting crane select the appropriate location of the lifting points and auxiliary traction and other measures; ③ 2m above aerial must have security protection, rain and wind than five stops operation in case of rain midway construction tower hoist must be installed in a safe condition; ④ boom lifting operation depends not turn, and let someone protection; ⑤ disassembly must strictly follow the order of the construction program requirements, installation frontier boom should not add weight, unassembled not lifting heavy weight. Demolition should be removed after the demolition of the counterweight boom; ⑥ Check the tower hoist the connecting parts are complete, reliable and effective, and its lifting, rigging and so on whether security.
3 hanging point selection
Assembly and disassembly of tower  Wire rope hoist  point selection and mounting methods are an important part of the construction to ensure safety, should pay attention to several issues. ① parts lifting point should be using a fixed location or special lifting point, when necessary, by their own design configuration. Side hanging, hanging oblique inclination should be to ensure reasonable. There are inner and outer structures lifting point should be selected when the structure of the inner sleeve to avoid internal and external isolation, such as TQ60/80  Wire rope hoist  tower spire. ② boom and the balance arm after lifting components such as to keep the horizontal and direction, the longer the mounting boom longitudinal direction as far as possible non-horizontal lifting method, the arrangement of the hinge end of the arm above the head end of the arm, hinged then the boom mounted to the horizontal position, as FO/23B 50m boom hoist tower and so on. ③ tower  Wire rope hoist  boom is hinged two parts into one assembly and disassembly when lifting point should be selected as the arm level, temporary connections rope force is smaller locations. ④ Remove the installation of reverse operation, more dangerous, should be strictly in accordance with the instructions on the construction plan their sequence assembly and disassembly operations, must reverse the order. ⑤ try not to use hooks Jia Shengsuo lifting heavy objects.
