In such a device, remote control is effected electrically. The di~tance between the control panel and the moving object may be suitably varied within the vi~-ibility range of the moving object during operation.
With the foregoing device, there is a real hazard that the operator may enter a dangerous zone, that is, a zone wherein the working member o~ the moving object per-forms its functions under control effected over a corres-ponding circuit. Thus, the operator may be injured by the working member of the moving object, lack of opera-tional safety being an apparent disadvantage of the afore-said device.
There is also known a device for controlling a mov-ing object (cf. Glukauf mining journal, 3(2), 1967, K.~,~eber - et al. ~Portable installation for remotc control ol .1in-ing equipm!nt by radio", pp 16 - 21~,which compri~s a port-able radio tran~mitter, a radio receiver and a control .- unit, all of ~hich are in~talled on a moving object. ~he - knorm device ensure~ con-trol of a moving object within 15 m. If thi~ di~tance i3 e~ceeded, the controlled object . i3 turned of~. Said moving object ma~ be controlled with ~ .

~ he knor~ device doe3 not provide operational sa~e-ty ior the operator may control said moving object in a dangerou3 zone. ~herefore, accidents may not be reliably prevented.

the ~econd input o~ the frequency divider 26.
The ~witch 5 compri~es a tran~istor 31 wherein the emitter is connected-to the zero potential bus 13, the collector is connected to the cathode o~ the light-emitt-ing diode 6 and the base i9 connected to the first output o~ the ~requency divider 26 through a resistor 32.
~ he anode of the light-emitting diode 6 and the ~irst input oP the encoder 3 are connected to one lead of the power ~ource 2 who3e other lead is connected to the zero potential bus 13 which is al~o connected to the se-cond input of the encoder 3.

~ aid infrared radiation i~ received by the photo-diode 9 (Figure 2) of the detector 3. A~ has been stated, the detector 3 and the photodiode 9 are arranged in the rear portion of the moving object 1~, an aperture in the photodiode 9 being turned in the direction opposite to the working member of the moving object 12. Such an ar-rangement o~ the detector 8 provides for ~ormation o~ the infrared radiation receiving zone B behind the moving ob-ject 12 since the photodiode 9 i~ beamed in the direction oppo~ite to the working member o~ the moving object 12.
The ~elective amplifier 10 (~igure 1) passes only the signal at the frequency of the generator 4. Thus, coded control instructions from the transmitter 1 appear at the output o~ the detector 8.
The decoder 11 permits obtaining initial instruc-tions, ~hile the control unit 7 effects control o~ the actuators of the moving object 12.
Said infrared radiation is received by the photo- -~
diode 9 only when the operator 14 (~igure 2) carrying the ;~
transmitter 1 is found in the reception zone B of the photodiode 9. Referring to the dra~ing it i3 apparent that the light-emitting diode 6 (Figure 1) of the trans-mitter 1 acting as a radiator mu~t be turned to the mov-ing object 12 (Figure 2). The configuration of the in- ;~
rrared radiation receiving zone B depends on the type of photodiode 9 used.
