The powered support MVPO 3500 is the supporting fence four props support for the blocking of the break out rooms in low or middle-thickness seams, that are flately located and it is used by the controlled caving method. The support is suitable for the seam bracking with the low rigid hanging walls. It is delivered for mining by the shearer and for ploughing of coal.

The suport MVPO 3500 is delivered in the range from 0,75 m to 2,1 m. It can be equipped by the telescopic double-acting props or props with the mechanical telescopic lengthening bar with the possibility of the safety blow-out valve mounting. Iit is possible to deliver the fixed or pull-out pre-roof bar. The basic frame is delivered with equipment for its tiliting during the support transfer and with the possibility of the compact frame or with the tilting front part, which facilitates the seam copying by the longitunidal fault of the extracted seam.. Supports are equipped by side hydraulic stablizing cylinders, that make required support levelling possible in dependence on inclination changes. The control of the individual support is hydraulic with the full flow of hydraulic liquid or impulse with multi-channel hose. The individual support parts are designed by computer method. Weldments are very rigid and they are made of very qualitative materials, which guarantee by their rigidity trouble-free operation in extreme conditions.

Basic technical parameters:

Working range: 0,85 - 2,0 m
Capability of support: 3 000 - 3 500 kN
Number of props per support: 4 pcs.
Max. face gradient along a pilar: ± 35°
Max. face gradient along mining strike: ± 25°

he powered support MVPO 4000 is the supporting fence four props support for the blocking of the break out rooms in low or middle-thickness seams, that are flately located and it is used by the controlled caving method. The support is suitable for the seam bracking with the low rigid hanging walls. This suport is delivered in the range from 1,3 m to 2,4 m.

This standing-fence support has a two pairs of props, the orientation of front pair is top-front and the orientation of rear pair is top-rear.

Slope of the roof bar it is possible to adjust by the relative position of front and rear pairs of props. The control of the individual support is hydraulic, impulse or by customers request. Support width is 1460mm. Supports are equipped by side hydraulic stablizing cylinders, that make required support levelling possible in dependence on inclination changes. The suport is equipped by the telescopic double-acting props with the possibility of the safety blow-out valve mounting. It is possible to deliver the fixed pre-roof bar.

Basic technical parameters:

Working range: 1,3 - 2,4 m
Capability of support: 4 000 kN
Number of props per support: 4 pcs.
Max. face gradient along a pilar: ± 35°
Max. face gradient along mining strike: ± 40°

The powered support is designed for coal mining by caving method in low thickness seams from 0,9 m to 1,4 m in variety of geological conditions. It consists of two pairs of hydraulic props in the shape of V with space for working among the props. The powered support can be used as a standing or standing-fence support depending on the slope of the roof bar. Slope of the roof bar is adjustable by the relative position of front and rear pairs of props. The control of the supports is electro-hydraulic manufactured by MARCO.

Supports are equipped with telescopic side with double side hydraulic stabilizing cylinders to cover space among the supports or to level relative inclination of supports. The front part of roof bar is equipped with tilting pre-roof bar controlled by 4 hydraulic cylinders. Support is equipped with ram equipment with hydraulic cylinder and auxiliary hydraulic cylinder destinated for lifting of front part of support frame to be able to replace support and transport the conveyer.

Basic technical parameters:

Working range: 0,9 - 1,4 m
Capability of support: 4 275 kN
Number of props per support: 4 pcs.
Max. face gradient along a pilar: ± 40°
Max. face gradient along mining strike: ± 30°

This is a shield support, designed for sub-level caving. It is equipped with a shield closure, a chute, a pillar support, lighting and dust wetting. The section of the support has got high stability. The foundation frame moves under a face conveyor with closed bottom side. Control of the support is by pulses - according to the customer´s needs. The support is suitable for floor with low carrying capacity.

Basic technical parameters:

Working range: 2,6 - 3,1 m
Capability of support: 2 400 - 3 200 kN
Number of props per support: 2 pcs.
Max. face gradient along a pilar: ± 10°
Max. face gradient along mining strike: ± 20°
