A stand which consists of sections type V29 and V32 is an immediate supporting friction stand, characterized by a nominal and working support which gives a possibility to use it in mine housing.
Currently company Dremex can offer a friction stands:
- type SV29, SV29t, SV29tw
- type SV32, SV32t, SV32tw
Stand is mainly designed for use as:
- an element of the straight support construction,
- an element which strengthens the existing arc housing or the one under construction,
- an element supporting binding joists and steel or wooden girders that strengthen the construction or directly support the rock mass.
Basic technical parameters of the stand:
Nominal support of the stand:
- Stand SV29180kN
- Stand SV29t280kN
- Stand SV29tw380kN
Working support of the stand:
- Stand SV29180kN ± 25%
- Stand SV29t280kN ± 25%
- Stand SV29tw350kN ± 25%
- Stand SV32200kN ± 25%
- Stand SV32t315kN ± 20%
