Heavy pressed SPT-SuC support feet heavy pressed SPT-SuC
- support feet are used in underground headings classified as "a", "b" or "c" methane explosion hazard level and class A or B coal dust explosion hazard,
- heavy pressed SPT-SuC support feet are intended for mounting side arches of the following dia. : V25, V29, V32, V34 or V36 sections.
- The SPT-SuC heavy pressed support foot consists of an appropriately shaped piece of metal sheet in which two stabilizing elements are pressed, forming a socket, arranged relative to each other in a way that allows for the correct installation of the V25, V29, V32, V34, V36 sections. The support foot may have an area of 400÷750 cm2 and a nominal thickness of 10÷14 mm. Depending on the surface of the foot, its length varies from 200÷300 mm, and its width, ranging from 200÷250 mm.
