Position；
Crossbeam is dropped to truck crane and does not stresses by 200 tons of truck cranes, the high-strength bolt on mounting flange；
Electrical equipment side leg large vehicle walking is turned to 90 °, and prepare to go on board shipping.
Further, in described step a, cart is dismantled electrical equipment side and is interfered the cable of supporting leg displacement, inclined ladder peace after turning to
Platform；Construct for workmen at electrical equipment side leg top mounting process platform.
Further, in described step c, before demounting bolt, first to pull up good wave wind rope to ensure electrical equipment at electrical equipment side leg
Side upright and stable, and dismounting wave wind rope before described step 5 electrical equipment side leg large vehicle walking turns to.
Further, described wave wind rope includes that one end is connected to 8 of supporting leg top, electrical equipment side two and both sides, bottom
Steel wire rope, the steel wire rope other end is connected with the corresponding balancing weight being positioned at bottom surface by 5T chain block.
It is an advantage of the current invention that: 1. by carrying out shipment shipping after being shifted by tyre crane supporting leg again, decrease tyre crane
Take up room, reduce cost of transportation；2. first dolly is travelled before displacement and be fixed to, near power side, add safety
Property, and due to the skew of center of gravity, truck crane crossbeam electrical equipment end of slinging is easier to；3. wave wind rope is installed on electrical equipment side leg carry out
Reinforce, it is ensured that in supporting leg shifting process, electrical equipment side leg will not topple.
Detailed description of the invention
The invention discloses a kind of tyre crane supporting leg displacement method, left side is the power side of tyre crane, and right side is tyre crane

1.3) cable, inclined ladder and the platform of supporting leg displacement is interfered in dismounting electrical equipment side；
1.4) construct for workmen at electrical equipment side leg top mounting process platform 2；
1.5) marine cradle 3 is installed.
Second step, marks line of displacement:
2.1) electrical equipment side crossbeam complete machine hanger centrage 5 and the centrage 6 of two crossbeams are marked on the ground；
2.2) the truck crane centre of gyration 7 is marked by electrical equipment side crossbeam complete machine hanger centrage and two crossbeam centrages；
2.3) centrage 8 after the saddle beam displacement of power side puts in place is marked.
3rd step, the bolt that dismounting girder is connected with electrical equipment side leg:
