Background

A crane safety device refers to a device that prevents the crane from being damaged in an accidental situation. Besides the common electric protection device, the sound signal and the color lamp, the crane also has various other safety devices for absorbing the kinetic energy when the crane or the trolley collides with the terminal block seat when the switch fails. Such devices are widely used with rubber, springs and hydraulic dampers, where the hydraulic damper is used on cranes or trolleys with high operating speeds (such as the trolleys of a carrying bridge) and absorbs a large amount of energy upon impact. Some cranes are also provided with photoelectric anti-collision devices to avoid the mutual collision of two cranes running on the same track. Its simple principle is: when two cranes approach to a certain safety distance, the light wave emitted by the projector of the crane A is received by the light receiver of the crane B, an electric signal is generated through the photoelectric tube, after wave shaping and amplification, the relay acts, and the buzzer gives an alarm and automatically cuts off the power supply of the running mechanism. Two cranes are respectively provided with one set of crane and interact with each other.
