Tandem powered support consists of two groups of paired girder and roof timber, group A and group B, with the function of self-advancing driven by hydraulic. The two groups support on one roof, when one group A starts advancing, group B provides support, thus there’s continuous support pressure. All movements are realized by hydraulic system, which requires simple operation skills.


Flexible Configuration

  • Side guard plate can be added for temporary protection

  • Pedestal can be enlarged for soft floor

  • Electrohydraulic control can be configured for remote control


Sphere of Application

  • Mechanized heading, blasting heading

  • Rectangular gateway, trapezoidal gate way, arched gateway and special-shaped gateway

  • Metal net, arched steel shed and other different supporting method

  • Winding gateway


Advantages of Tandem Powered Support

1. Continuous supporting force to roof

2. Large canopy guard area with high supporting strength

3. Rapid advancing and quick metal net laying

4. Supporting in time to ensure safety

5. Customizable dimension according to gateway actual space size, small occupied floor area

6. Easy operation by self-advancing

7. Replaceable to existing gate-shed

8. Customizable design for different types of gateway

9. Alternative control method including hydraulic centralized control or electrohydraulic control, and realize remote control.


Practical Application of Tandem Powered Support

Because of special structure and principle, the tandem powered support is widely applied to many kinds of gateway/tunnel, including rectangular gateway, trapezoidal gate way, arched gateway and special-shaped gateway, the practical applications are as below:

  • 1. Temporary roof rock support in rapid coal/rocks advancing and tunneling occasions: multiple heading with one anchor bolting in mechanized heading, anchor bolting while heading in mechanized heading, rapid blasting heading.

  • 2. Working face terminal roof support

  • 3. Working face forepoling roof support

  • 4. Replaceable to existing gate-shed

  • 5. Vertical shaft supporting

  • 6. Exploiting non-coal mines like underground copper mine, manganese mine and phosphorite mine

  • 7. Other tunnel exploiting and advancing like water conservation, transportation and railway.
