Deflection angle detecting device of suspended load rope and crane having the same

摘要

Problem to be solved: to provide a shake angle detecting device and a crane provided with the deflection angle detecting device capable of stably detecting information about the deflection angle in the longitudinal direction and the left and right direction of the suspension load rope.The shake angle detecting device 60 comprises a first oscillating member 61, a second oscillating member 62, a first rocking connection portion 60t and a second rocking connection portion 60s.The first rocking connection portion 60t connects the first rocking member 61 and the boom tip portion 16q to each other so that the first rocking member 61 and the second oscillating member 62 can be swung together about the first rotation center axis CL1.The second rocking coupling portion 60s couples the first oscillating member 61 and the second oscillating member 62 to each other so that the second rocking member 62 can be swung relative to the first pivot member 61 relative to the second rotary central axis Cl2.The swing angle sensor 63 is mounted on the second oscillating member 62 to detect the angle of deflection of the main winding rope 51 in the forward and backward directions and in the lateral direction.Diagram
