The invention discloses a rail-crossing crane. The rail-crossing crane comprises a rail beam capable of travelling at the lower end of a crane beam, wherein a driving air cylinder capable of controlling the rail beam to move is arranged on the crane beam; hoists are arranged at the lower end of the rail beam, the two ends of the rail beam are provided with hoist limiting plates used for limiting the travelling range of the hoists and starting and stopping air cylinders used for controlling the rotation angle of the hoist limiting plates, and locking devices are arranged at the two ends of therail beam correspondingly; and an air compressor for providing power for the driving air cylinder, the starting and stopping air cylinders and the locking devices is further arranged on the crane beam. According to the device, by moving the crane beams and rail beams, rail butt joint of the rail beams on two cranes at any position except stand columns of workshops can be achieved; and the cranes can be limited and locked at any position and any time except the stand columns of the workshops through the locking devices, and the hoists can be controlled to move to another rail-crossing crane, sothat the working efficiency is greatly improved.

    本发明公开了一种过轨起重机,包括能够在行车梁下端行走的轨道梁,行车梁上设有能够控制轨道梁移动的驱动气缸,轨道梁下端设有葫芦,轨道梁的两端设有用于限定葫芦行走范围的葫芦限位板和用于控制葫芦限位板转动角度的启闭气缸;轨道梁的两端均设有锁紧装置,行车梁上还设有为驱动气缸、启闭气缸以及锁紧装置提供动力的空压机,本装置通过移动行车梁和轨道梁,可以实现两个起重机上轨道梁在厂房立柱之外的任意位置对轨,通过锁紧装置实现起重机在厂房立柱之外的任意位置、任何时间进行限位锁定,能够实现控制葫芦移动到另一过轨起重机,大大提高了工作效率。
