DEVICE FOR DETECTING SWAY ANGLE OF SUSPENDED LOAD OF CRANE

摘要

PROBLEM TO BE SOLVED: To provide a device for detecting a sway angle of a suspended load of a crane, capable of precisely detecting a sway angle of a suspended load in real time with a compact and simple mechanism, without requiring angle conversion by a controller or without constraints on assembly such as causing the length of a detection rod to be a specific length or more.;SOLUTION: A detector body 17 provided with a MEMS inertial sensor detecting a two-axis angle or angular velocity about a luffing axis 13 parallel to a crane luffing center axis and a horizontal pivot 14 orthogonal thereto is suspended from a crane distal end 1 via a suspension member 16, and the detector body 17 is provided so as to be movable relative to a wire rope 2 hoisting up and down the suspended load and capable of following the sway angle of the wire rope. Accordingly, the detector body 17 suspended by the suspension member 16 can follow the sway of the wire rope 2, and the sway angle is precisely detected in real time by the MEMS inertial sensor provided at the detector body 17. The device is thereby made compact.;COPYRIGHT: (C)2013,JPO&INPIT
