Is intended for work with taking-out narrow-cut combines or ploughing facilities.
The powered support 1М2 consists of two-props sections with four-chain linking system of the basis with the barrier and the rigid-linked integral ceiling. Replaceable visor of the ceiling allows to operate the support with variable composition of abatement equipment in the longwall. The basis of the section – hinged or rigid-linked catamaran-type. The section advance – plunger end of the hydraulic cylinder. Extension boards management for the section adjustment in the seam plane and workspace protection under the support against small stuff – independent separate double-sided.
