|250 ton Europe style electric overhead traveling crane|
This Euro-style double girder overhead crane with winch trolley is of higher workduty, which can reach A7, A8,large tonnage, such as 50 ton, 80 ton, 100 ton, 200 ton, 300 ton, 500 ton.
It is of advanced technology, whose design is based on international standard: FEM (Europe), DIN (Germany), ISO(International), equipped with many advantages such as: strong rigidity, light dead weight, low power, outstanding structure design etc. Of top configurations, such as Schneider electricals, ABMrd / SEW/Siemens triple gear motor (three in one: motor, gear box, brake), galvanized high strength wire rope, self-adjusted disk brake, hard tooth reducer, programmable lifting limit switch, and so on.
|Key Components~~Top configurations, SEW geared motors, Schneider electricals, PLC, VFD, VFD, Cabin|
|Crane trolley, End carriages, wheel blocks|
Independent Trolley Mechanism:
It applies lightweight design, direct acts the lifting load on end carriages of trolley frame both sides. With clear force and compact layout, it has high driving efficiency, low noise, low crane height and low dead weight
Trolley Traveling Mechanism:
It is of triple compact design of motor, reducer, brake. The motor is of F insulation class, IP55 protection class, 40% load continuity rate; with thermal protection, power-distribution magnetic disk brake and reducer with hard gear surface which has been grinded or gear shaved. It’s not necessary to replace the oil in gear box during the work lifetime. It has forged wheels, wheel rim and the hardness of tread surface of HB330-380. It adopts the VVVF control speed---low speed at heavy load, fast speed at light load; adjusting range is 1:10; with stable traveling, no impacting. Trolley Limit switch adopts the cross type traveling limit switch, which can reduce the speed to zero before the collision of buffer with blocks of the rail end.
