1. Haulage transporter lines control system consists of a set of arterially connected modules, including start-up, timer, central automation, multiplication of sets of contacts and warning signals, while the modules are powered by spark neutral inputs, which are also connected with the circuit breaker switch of conveyer belt or with the line cut out switch, while each of the conveyers works in concert with the excess output sensor, temperature sensor, conveyer speed and slippage sensor and with emergency switch; is characterised in that it includes delay block (2) powered by spark neutral combine loader circuit switch (W1) via bridge rectifier (1), whose positive output terminal is connected in parallel with the emitter of the keying transistor (T1) and via serially connected separating condenser (C1) and resistor-potentiometer divider (R1, P1, R2) with transistor mass(T1) while the negative terminal of the rectifier's output (1) is connected through the direct current relay voltage coil (2PDT-1) with transistor collector (T1), while the transistor base circuit (T1) is controlled from circuit containing auxiliary set of contact (PP1) of the variable current relay (3PDT-1) connected with contact (S1) switching off the combine cutter power...<IMAGE>
