Electrical Equipment and Automation Systems

• Pit Shafts Signal System Pit Shafts Signal System MASS is designed for coordination of process personnel actions and control of hoisting unit during trips of men, cargo and oversized equipment, as well as during examinations, inspections and overhauls in the pit shafts and head frame rig, and is also used in man, man-cargo and cargo hoisting units of mines (pits).

• Mine Shaft Wireless Communication System, Rope Slacking Prevention Mine Shaft Wireless Communication System is designed for coordinating actions of technological personnel and operators of mine hoisting machines when carrying out work on descent and ascent of people, audits, inspections and repair work in mine shafts, monitoring condition of sensors of lifting vessels (mine cage or skip) and issuing control signals to control circuit of mine hoisting machines.

• Loudspeaking and Warning Signal System Loudspeaking and Warning Signal System is designed for talk-back communication and signaling within range of long wall set of equipment and with mine (pit) supervisor, interlock of power train switches mounted on the entry; indication of states of technological protections, machines and mechanisms of the complex, as well as for talk-back communication along shafts.

• Laser Alignment System UNL The Laser Alignment Systems UNL are designed for fixing horizontal and incline reference directions in tunnels and mine workings, hazardous in mine gas and combustion dust. The Laser Systems UNL can be used for mining and tunelling.

• Frequency Converter Ex (explosion-proof) with air-cooling

• Control Station Control Station is designed for remote control (switching on and off), protection of asynchronous electric motors with short-circuited rotor (from 1 to 10 pc) against overload currents and short-circuiting, and diverging connections in mine electric networks with transformer insulated by neutral.

• Mine Power Unit Mine Power Unit is designed to provide control and automatic devices with DC stabilized voltage and AC non-stabilized voltage, microprocessor systems of industrial equipment, as well as provide automatic devices with information on presence of supply voltage at the unit output by means of discrete output.

• Explosion-Proof Lamp Explosion-proof luminescent lamp is designed for general illumination of underground mine workings, shafts and their above-ground buildings hazardous in mine gas and/or combustible dust of faces, and mine workings hazardous in gas and dust, in mines and pit shafts.

• Intrinsically Safe Power Supply Unit type ZIM

• Movement Control Sensor Movement Control Sensor is designed for monitoring movement of movable operating elements of face and gate drag conveyers in underground mine workings hazardous in explosion of gas and dust.

• Reed Magnetic Sensor Reed Magnetic Sensor is designed for control of object position and generation of signals about location of object in given zone. The sensor can be used in underground main workings of shafts and pits, including salt ones hazardous in mine gas.

• Electronic control units and relays Electronic control units and relays for installation in mining electrical equipment (compact stations and control stations) and contactor starters.
