Main girder of gantry craneBe welded of steel plates with honeycomb hole, connected by high strength precision bolt.There is sliding rail for trolley to travel upper the girder which is fixed on outrigger by high-tension precision bolt.2. Traveling mechanism of gantry crane-consists of driving gear box and passive wheel box- the driving gear box supplies power to finish the crane' travelling.-What the difference between driving gear box and passive wheel box is that passive wheel box lacks transmission structure such as dynamo, resucer and a pair of exposed gear.3. Cabin of gantry crane-Glass window can make the operator see all the working condition and the cabs installed in the front and two sides- As a group of independent cabin, fixed outside of cab is connected by control cable and linkage station which is set up in thecab.4. Trolley with gantry crane- the trolley is assembled with motor, reducer brake, trolley frame, hook, pulley, rain cover and other parts.- Include lifting mechanism and crossing travelling mechanism.- the trolley is strictly designed according to the application and working environment.5. Electric system of gantry crane- Hoisting motor, long traveling motor and hydraulic power motor are included.-The whole electric system is controlled by PLC(programmable logic controller).-Two operation modes: cabin and remote control. Company ProfileHenan Eternal WinMachinery Equipment Co., Ltd, established in 1998, located in crane hometown, which integrates the R& D, manufacture, sales, installation and service of all kind of overhead crane, gantry crane, ship crane, spider crane ect lifting equipment.
