The powered support 1М22 consists of two-props sections with four-chain linking system
of the basis with the barrier; the ceiling with extensible console, equipped with the
flap visor with enhanced effort and device for face keeping (from H ≥ 2.5 m). Extension
boards and a pusher-jack (with a landside) installed onto one side are used in the section.
It is possible to reinstall hydraulic cylinders, boards and pusher-jack onto another side.
Landside location in front area ensures the adjustment of the section basis by every
order of their extension. Increased resistance of the support is ensured due to maximum
diameter and working pressure in hydraulic props. Apply of spacers in the basis and
hydraulic props of the section considerably expands the field of application with
required power parameters.
