The Laboratory of Tests conducts the tests of powered roof supports for conformity with the safety requirements acc. to items 5.1 ÷ 5.3.7 of PN-EN 1804-1+A1:2011 Standard.
The scope of fatigue tests of powered roof support includes as follows:
tests of static strength of powered roof support components acc. to item A.1.2 of the Standard,
tests of fatigue strength of powered roof support components acc. to item A.1.3 of the Standard,
tests of strength of front canopies of powered roof support acc. to item A.5 of the Standard,
tests of static strength of transportation catches acc. to item A.4 of the Standard,
tests of powered roof support yield acc. to item A.1.2.4 of the Standard,
tests of static strength of fixation of legs and cylinders of powered roof support acc. to items A.1.1 and A.1.2.3 of the Standard,
tests of static strength of additional equipment of powered roof support acc. to items A.1.1, A.1.2.1 and A.1.2.2 of the Standard.
The scope of functional tests of powered roof support includes determination of linear dimensions, angles and angles of loosing the stability realized within the following:
verification of conformity of basic dimensions with technical documentation,
verification of easiness of assembly and disassembly,
verification of width and height of passage for personnel,
verification of functionality and controllability of powered roof support,
verification of stability of free-standing powered roof support,
verification of cooperation of roof supports on inclinations.
