发明名称 SELF PROPELLED ROOF SUPPORT
摘要 The movable consolidating trestle (2) has driven caterpillars (1). The consolidating trestle comprises a cap (3) being supported on the frame (11) via props (5). The cap (3) has at least one front-side section which is bent, rounded or bendable in direction to the frame. A bent section (8) includes with the plane of the cap (3) an angle ( alpha ) which is greater than the maximum angle ( beta ) of inclination with which the cap can be obliquely adjusted relative to the frame (11). When giving the cap (3) an inclined position, there results a horizontal component of the load-exerting force (14), said horizontal component facilitating saving of the consolidating trestle.
