The device of protection of the PZK-10 crane is intended for protection of luffing cranes against overloads and capsizing at lifting of loads, protection of operating equipment and load against damage during the work to the constrained conditions or in power transmission line zone (coordinate protection), and also for display of information on condition of the crane.
1.2 PZK-10 represents the aggregated complex consisting of the block of data processing and converters.
1.3 Assignment of constituent parts of PZK-10 is provided in table 1.
|Data processing block||Processing of signals of converters, general management of work of PZK-10, control of cargo characteristics, management of the relay of shutdown of mechanisms and indication of parameters of operation of the crane|
|Pressure converter||Transformation of pressure in hydraulic cylinder of raising of arrow in electric signal|
|Corner converter||Transformation of tilt angle of arrow and turning angle of platform to electric signal|
|Effort converter||Transformation of effort in delays of rope of raising of arrow in electric signal|
|Length converter||Transformation of length of the telescoped arrow to electric signal
