Disclosed in the present invention is a crane, method and apparatus for monitoring the swing angle, weight or gesture of the crane load, belonging to the technical field of crane; the purpose of the present invention is provide an apparatus for monitoring the swing angle, weight or gesture for the crane's hoisting, and to provide a crane which comprises aforesaid apparatus; when hoisting a load, the swing angle, weight or gesture are displayed in both the native crane cab and the collaborative crane cab by wireless transmission and switching channels in the cab; then, not only can the drivers operate the cranes to eliminate the deflection of load and achieve the vertical hoisting according to the load's swing angle of each crane displayed on the screen, but also operate the cranes to make balance of weight distribution according to the real-time ratio of load weight or load gesture. |

1. An apparatus for monitoring the swing angle and the weight of a crane load, comprising:
a monitoring device of the crane load's swing angle installed as follows: on the outside of a guard plate of a movable pulley of the lifting pulley block of the crane, or on the inside vacancy between the two length-extended sides of the guard plate; wherein the monitoring device further comprises:
a platform fixed, whose surface becomes a horizontal plane when the crane load's swing angle is 0 degree, thereon an angle measuring instrument is installed,a wireless swing angle transmitter with two channels switched by a remote controller which is positioned in a crane cab, to transmit the crane load's swing angle signals which are generated by the angle measuring instrument, as well as two wireless swing angle receivers with two switchable channels installed in the crane cab to receive the crane load's swing angle signals,or a wireless swing angle transmitter with three channels switched by a remote controller which is positioned in the crane cab, to transmit the crane load's swing angle signals which are generated by the angle measuring instrument, as well as three wireless swing angle receivers with three switchable channels installed in the crane cab to receive the crane load's swing angle signals; a monitoring device of the crane load's weight which further comprises: a load weight detector installed on the crane, meanwhile a wireless load weight transmitter with two channels switched by a remote controller which is positioned in the crane cab, to transmit the crane load's weight signals which are generated by the load weight detector, as well as two wireless load weight receivers with two switchable channels installed in the crane cab to separately receive a native crane's load weight signals and a collaborative crane's load weight signals, or a load weight detector installed on the crane, meanwhile a wireless load weight transmitter with three channels switched by the remote controller which is positioned in the crane cab, to transmit the crane load's weight signals which are generated by the load weight detector, as well as one wireless load weight receiver with three switchable channels to receive the native crane's load weight signals and two wireless load weight receivers with three switchable channels to receive the collaborative crane's load weight signals which are all installed in the crane cab, at least one load ratio processing monitor installed in the crane cab to display the real-time ratio of load weight, the two inputs of which are respectively connected to the output of the wireless load weight receiver receiving the native crane's load weight signals and the output of the wireless load weight receiver receiving the collaborative crane's load weight signals. |
