HOISTING OR CONSTRUCTION MACHINE LOAD LIMITER (VERSIONS)

摘要

FIELD: transport. ^ SUBSTANCE: proposed device comprises load transducers and azimuth pickup connected to control device. Load transducers may measure mechanical stresses or deformation in two directions or load vector components. Load transducer may be arranged in equipment hinge assembly. Control device allows smooth or jump variation of maximum tolerable load depending on time, operating conditions or machine load stage, setting of minimum tolerable load in the machine operating range depending upon azimuth, storing and varying it depending upon azimuth. In case maximum tolerable load value is exceeded, control device generates warning signals for crane operator or machine interlocking signals. ^ EFFECT: higher safety and efficiency. ^ 24 cl, 2 dwg
