CONTROL SYSTEMS

ELECTRO-HYDRAULIC CONTROL

Electrohydraulic control is used for parallel control of the mining cover sections which can perform from 2 to 22 control functions.

Electrohydraulic control is composed of a performance block equipped with 3/2 way performance valves as well as with pilot valves to control the particular functions.

PILOT CONTROL

The pilot control is used for parallel control of the mining cover sections which can perform from 2 to 24 control functions. Due to the small force needed for control and increased throughput of the dividers, it is especially useful for high-efficiency wall complexes, cover sections with high diameter of hydraulic supports as well as everywhere where short time of the section spacer is required.

The pilot controls are in divisible and compact versions.

  • DIVISION PILOT CONTROL

The divisible version of the pilot control has a control block and a performance block connected with a multi-duct conductor.

  • COMPACT PILOT CONTROL

The compact version of the pilot control is characterised with the connection of the control and performance blocks into one.

DIRECT PILOT CONTROL

The direct pilot control is used for parallel control of the mining cover sections which can perform from 2 to 18 control functions. Due to the small force needed for control and increased throughput of the dividers, it is especially useful for high-efficiency wall complexes, cover sections with high diameter of hydraulic supports as well as everywhere where short time of the section spacer is required.

  • DIRECT CONTROL

 The direct pilot control is used for parallel control of the mining cover sections which can perform from 2 to 12 control functions. The hydraulic dividers directly control the servo-motors the cover section is equipped with.
