Further, also comprise two of the being connected to crossbeam attaching parts span direction pull bar between mobile trolley used, described pull bar mobile trolley usedly laterally is connected as a single entity when the load traveling two, reaches to eliminate the various external force that the walking wheel on mobile trolley used produces the crossbeam attaching parts.
Further, connect and compose rigid body by link span between described two groups of crossbeam attaching partss.
Further, the crossbeam of described crossbeam attaching parts is Split type structure, and two sections crossbeams connect by connecting external member.
Further, described connection external member is provided with a series of connecting bores, two sections crossbeams by be connected external member different connecting holes position and connect and realize the crossbeam length variations.
Further, described rope suspender is connected with crossbeam by connecting the part cover, and even the part cover can slide along crossbeam.
Further, described rope suspender with connect the part cover and directly be connected or connect by hydraulic actuating cylinder.
Further, described hydraulic actuating cylinder is controlled for interlock.
Further, described mobile trolley used be set to possess turn to, power walking function or possess separately the power walking function.
Owing to having adopted technique scheme, the invention has following beneficial effect:
1, consist of rigid body and set up two crossbeams between the crossbeam attaching parts of two groups of front and back, thereby make the crane of the invention possess corresponding weight capacity, complete the lifting of many tonnages object.
2, the height adjustable buttress supports gantry beam, realizes the adjusting of gantry beam terrain clearance, and is required to satisfy different lifting objects and to lift application.
3, the bearing height adjustable buttress is mobile trolley used, realizes that car load turns to and traveling flexibly.
4, the rope suspender can be along cross beam movement, realizes the adjustment of multi-faceted, the multi-angle of the height of lifting object and position, left and right, thereby realizes fast and accurately with the lifting object exactitude position.
5, the rope suspender with connect the hydraulic actuating cylinder that the part cover controls by interlock and be connected, just fluctuating situation of ground, place is transferred to the hydraulic actuating cylinder oil level just, thus on the guarantee crane, four suspension centres of lifting object is stressed identical.
