Adopt the structure design of the utility model; Two of assembly units lift main truss at the construction field (site); Lift two lifting main trusss respectively to Dun Ding with tower crane, and carry out the anchoring of main truss with fining twisted steel anchor pole and fixing steel plate, forward and backward crossbeam of welding and straight skidding track are linked to be a whole truss with two lifting main trusss on two lifting main trusss; As promoting support body, through hoist engine, wire rope and slippage i iron, assembly pulley heavy steel support is risen to Dun Ding then.
Be fixed with between said straight skidding track and the lifting main truss and strengthen column and diagonal brace, can further strengthen the resistance to overturning between straight skidding track and the lifting main truss.
In order to reduce construction cost, handled easily, said lifting main truss adopts the Hanging Basket main truss, is the Hanging Basket main truss of construction semi girder.
Compared with prior art, the utlity model has following advantage:
1, make full use of turnover material such as member on the Hanging Basket as the truss that promotes bearing, practiced thrift cost, safety has also obtained guarantee, and the scope of application is wide, can reduce construction cost;
2, construction technology is simple, easy operating, and safety is controlled;
3, less equipment investment, mechanization of building operation is less demanding, and construction safety risk is little;
4, the construction plant is less demanding, has solved the difficult problem of narrow and small, the high pier in place, the lifting of heavy bearing.
In a word, adopt the described hanging apparatus of the utility model to construct, significantly reduced construction cost, practiced thrift construction cost, have good economic benefit and social benefit.
