Is intended for work with taking-out narrow-cut combines.
The powered support 1М20 consists of two-props sections with four-chain
linking system of the basis with the barrier and the rigid-linked or integral
ceiling ensuring the highest effort to support the hanging wall. The basis of the
section - rigid-linked catamaran-type. Extension boards management for the section
adjustment in the seam plane and workspace protection under the support against small
stuff – independent separate double-sided.
