Arched metal supports KMP-A (KMP-AU)

Арочные крепи металлические КМП-А (КМП-АУ)
Application area

Frame supports metal malleable KMP-A (KMP-AU) are used for fixing capital and preparatory mining workings of mines and mines. Metal pliable arched support KMP-A can be manufactured (depending on the mining and geological and mining technical conditions of the customer):

  • - three - link;
  • - four - link;
  • - five - link;
  • - with a reverse vault.

Metal pliable arch support in four-door and five-door versions is used in large cross-section workings, as well as in conditions where high pliability of the support is required.

Arched support with a reverse arch is used in mine workings with weak soil rocks or prone to heaving.

Completeness

  • the upper part and the racks are made of a special interchangeable profile;
  • locks;
  • spacer brackets;
  • struts;
  • passport.

* - It is allowed to manufacture supports of lighter rolled profiles from high-strength steels in case of their equivalence in bearing capacity with a replaceable profile.

** - For upgraded fasteners manufactured from January 1, 2006.

Note: the characteristics of the supports are given from lighter rolled profiles made of high-strength steels, equivalent in bearing capacity to the replaced profiles SVP 22, SVP 27 and SVP 33.

Meets the requirements of technical specifications 25.11.23-003-16375400-2020 and GOST 31560-2012.
