The SKL 25 and SKL 29 clamps

The SKL 25 and SKL 29 clamps are intended for connecting the parts of the roadway support made of V25 and V29 shapes in mining workings exposed to static and dynamic rock mass pressure. They can be used in the ŁP frames, SV props and for untypical constructions of flexible and rigid connections.

The manufacturing programme comprises three types of clamps:

 SKL 25G and SKL 29G top clamp – intended for installation at the end of the external shape in the connector, e.g. of the side wall arch,
span> The bottom SKL 25G and SKL 29D clamp – intended for installation at the end of the internal shape in the connector, e.g. of the roof arch,
 The middle SKL 25S and SKL 29S clamp – intended for installation between the top and bottom clamp.
