Conventional configuration: 1) Room control. 2) Driver`s room is opened or closed types. 3) Wound rotor motor is used on each mechanism, changed speed by resistance. 4) Working ambient temperature: -10° C~+40° C. Other configuration user can choose: 1) The wired ground control, convenient for use and control. 2) Fixing wireless remote control to realize the remote control. 3) Changing speed brake method: Pole changing control, plug braking, dynamic braking, frequency control, etc. 4)The other feasible configuration user propose. Features: 1) Reasonable structure 2) Favorable performance 3) Smooth starting and stopping 4) Safe and reliable traveling 5) Low noise, commodious cabin and good view 6) Convenient maintenance, excellent exchangeability for parts and components 7) Saves electricity Mostly used for outdoor processing and material handling, gantry cranes consist of a two legged A-frame support. Gantry cranes also come with cantilevers. Cantilevers are a projecting structure, supported at one end and used for carrying a load at the other end or along the length. There are three types of gantry cranes, including single girder cranes, truss girder and double girder cranes.
