SELF-PROPELLED BOOM CRANE WITHOUT ROTARY PART CONTROL SYSTEM Russian patent published in 2020 - IPC B66C13/18 

FIELD: transport machine building.

SUBSTANCE: disclosed is control system of boom self-propelled crane without rotary part. System comprises interconnected controller (1) and display-controller (2), to outputs of which are connected light signaling device (6), audio signaling device (7), control device of crane (15). Analog sensors of working equipment of crane (3, 4, 8) are connected to inputs of controller (1), for example, pressure sensors, force sensors, angle sensors and digital sensors (9, 10, 11), by means of CAN-line, control elements (12, 13), limit switches (5). Controller (1) and display-controller (2) are configured to start the algorithm of the operating method and adjust the control system, maintain the system log, generate electrical signals for the discrete or proportional control of the valve. At that, display-controller (2) is additionally made with possibility of switching with analogue sensors (3, 4, 8) of crane working equipment and digital sensors (9, 10, 11) by means of CAN-line. Each analogue angle transducer comprises a sealed damping fluid-filled housing, inside which there is a sensitive element, on which there is a pendulum configured to deflect by angle of 110 degrees, consisting of a shoulder with an axis on which the plumbs are fixed.

EFFECT: enabling higher reliability.
