Abstract

Provided is a method of detecting the swing angle of a crane by use of an inexpensive and simple inclinometer. The method of detecting the swing angle of a crane is for detecting the swing angle of the rope of a container crane or the like that hoists cargo using a wire rope to transport it. Electric power and signal lines can be supplied to a spreader. An inclinometer is installed at the spreader and a head block to detect the horizontal inclination of the spreader. If the rope does not sag while the spreader is swinging, the swing angle of the spreader is calculated based on the detected inclination angle of the spreader.

Description

technical field [0001] The invention relates to a method for detecting the oscillation angle of the hoisting load of a container crane, in particular to a detection method for the oscillation angle of the hoisting load which has high detection accuracy and can reduce the cost of the crane system. Background technique [0002] Conventional container cranes are cranes used for container stacking and destacking operations when the containers used as lifting loads are transported from sea to land, from land to sea, or between land transportation. During the stacking and unstacking operation of the container crane, if the hoisting load vibrates, it is very unfavorable for the efficiency of time utilization for the handling operation of the container, and the result is an increase in labor costs. The entire logistics also took a lot of time. [0003] For the vibration of the load lifted by the container crane, for example, a visual sensor such as a CCD camera was once installed o...
