A brief of introduction	It is a kind of heavy duty crane ,it is widely used in plants, warehouses, materials stocks to lift goods or materials. This crane mainly consists of strong bridge beams,crane traveling mechanism, electric winch trolley and electric system,and could be classified into several working duties,e.g.A5,A6,A7,according to the working frequency and pure working time.
Feature description	1.High quality thanks to proven crane components 2.Particularly high performance thanks to the double-girder design which enables high 3.long and cross-travel speeds to be achieved 4.Low deadweight reduces investment layout 5.Possible fittings: Optional maintenance platform for maintenance of your building 6.fittings and operation of the crane by means of cabin or radio control
Mechanical feature	1) Double welding box girder, DIN/FEM standard deflection. 2) Material Q235B or Q345B. (Similar to the international steel Fe360 or Fe520) 3) Whole length CNC cutting for complete web plate, high deflection accuracy. 4) High quality automatic welding and NDT inspection. 5) Shot-blasting Sa2.5 for complete girder after welding, stress release. 6) Epoxy zinc rich high quality painting, 2x2 with 140m. 7) 10.9 class High tension bolts mounting between girder and legs, life time safe connection. 8) Double flanged or flat wheels, anti-friction bearings, cellular buffers, derailment protectors. 9) Full-length service platform along the crane bridge is supplied, where it is equipped with protective hand railing and toe strips.
Electrification and outfitting	1) Conductor power supply. 2) Phase control guard opens the main contactor in case of phase failure. 3) All hoist and crane movements are independent and can be run simultaneously. 4) Contactors meet crane applications, rated for severe vibration. 5) The control panels are finished to withstand corrosion, IP55. 6) Heavy duty plug head 7) The components are positioned in a maintenance friendly way, and the whole layout provides good protection against accidental contact. 8) The multi-wire type fixed cables with plastic insulation are intended for crane usage. 9) Cables are coded either with numbers, colors or tags for easy identification. 10) The flate cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists. 11) Festoon cables are suspended on cable saddles, fixed to cable trolleys, running in a galvanised C-track, which is connected to the main girder with bolted or welded support brackets.
Safety protection	1) Rain cover for outside hoist, driving units, electrical cubicle. 2) Warning indicator: flashing lights and warning sound. 3) Wireless infra-detector for anti-collusion 4) Various safety limit
Control mode	1) Pendant Independent festoon station or fixed suspended under hoist. Protection class IP65. 2) Remote Control Easy control, no additional driver, remote access. Two steps push button or joy stick station with emergency stop. Protection class IP65. 3) Cabin Control Professional chairs, adjustable and fully turning. Multi-faceted window, big view. Two steps push button or joy stick station with emergency stop
Advantage	1). Compact design, optimal use of the size of work areas 2). Control the load easily and position the load exactly 3). Superior safety and reliability 4). Minimum& Easy maintenance 5). “One-Stop Shop” for your crane and hoist needs
