Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Universal gantry crane mainly by car, the door frame, carts run and electrical device component. Partial main beam dual-beam rail box-shaped structure, legs and lower beams composed of A-type. According to requirements, the door frame generally have one or two cantilever. Gantry comprises a main beam, the beam, lower beam, saddle, legs and other parts mg ladder platform type, when there is no boom without a saddle. The upper beam as the main walkway with railings, car conductive vertical frame are mounted on the main beam cover. Gantry cranes (News http://www.qizj.net/html/news/) lifting trolley from small frame, since the composition of lifting mechanism and trolley traveling mechanism. Small frame from welded steel, used to place the working bodies. Hoisting mechanism for vertical lifting items, by the drive means (motor, reducer, brakes, etc.) and the winding device (drum set, rope, pulley, hook group etc.). Cab addition to the installation of control equipment has operated the crane, there were a total power gantry crane emergency off switch, power indicator and overload limiter display and other instruments. The door has a ladder platform mg double girder gantry crane for easy entry into the cab driver from the ground, and another on the platform leading to the bridge walkway ramp ladder for maintenance personnel to use. Universal gantry crane use of environmental conditions: (1) three-phase AC power supply crane, the frequency is 50HZ, voltage is 380V. Electric motors and limit the allowable voltage fluctuation rated voltage 10% mg double girder gantry crane hook, the lower limit (peak current) for the rated voltage of -15%, where the crane internal voltage loss in accordance with: nominal weight of 32t and 32t for 5% mg or less double girder gantry crane, 32t to 160t of the above, the internal voltage loss of 4%. (2) Installation of universal gantry crane orbit should comply with GB10183 requirements. (3) The crane installation site altitude does not exceed 2000m. Be checked when the motor capacity to deal with more than 1000m. (4) General gantry crane ambient temperature should be within normal range of -20 ~ + 40 ℃, 24h average temperature must not exceed + 30 ℃. (5) The work environment may not have flammable, explosive and corrosive gases. (6) lifting items radiant heat on the crane hook portion may not exceed 300 ℃. (7) General gantry cranes working pressure of not more than: a, inland 150Pa (the equivalent of six wind) b, the coastal 250Pa (equivalent to seven wind) Maximum pressure (8) Cranes non-working state is not greater than 800Pa (equivalent to 11 wind) NOTE: Customer proposed cranes poor environment, beyond the above conditions, should be used as non-standard products, special design.
