METHOD OF SAFETY DEVICES ADJUSTMENT OF CLIMBING CRANES OF JIB TYPE WITH EQUAL CRANE EQUIPMENT Russian patent published in 2010 - IPC B66C15/06 B66C23/88 

FIELD: machine building.

SUBSTANCE: invention relates to pick-and-place machine building, particularly to method of adjustment of safety device of climbing cranes of jib type with equal crane equipment. Method includes mounting of adjusted device on outfitted crane, connection to it load transducer and attitude position transducers of jib type equipment and adjustment of signals in measurement of load channels, outreach and/or angle of slope of jib from condition of providing of correspondence of run-down characteristic of device to specified cargo properties of crane. Method includes copying from nonvolatile memory of safety standard instrument, adjusted in advance on single-type, standard crane with usage of tare cargoes of specified weight, into nonvolatile memory of adjusted device information about measured values of load, boom and/or angle of slope of jib in points of cargo property of crane with known parametres of boom equipment. Copying is implemented before and after mounting of adjusted device on new outfitted crane or on crane, which is in operation after its relocation with removing of transducers and its following installation during crane mounting. After mounting of adjusted of transducers on outfitted crane and connection to its of transducers it is installed boom of outfitted crane into one of positions in the limits of working range angles of slope and azimuth, there are measured parametres of its boom equipment in particular position of boom and there are adjusted signals in channels of load measurement, boom and/or angle of slope of jib by means of addition of pickup signals of adjusted device with signals, corresponding difference of values of pickup signals on measured boom of outfitted crane and equal to it boom of standard crane.

EFFECT: achieved decreasing of labour-intensiveness of safety device adjustment.
