The device has cantilever controllers for controlling the cut horizon of an extraction machine, especially a plane for a coal mine, a joint pan connection for admitting a ball joint of an arm cylinder and with one forked arm offset with respect to the joint pan connection for attaching the head part of an arm bar by means of a hinge pin, whereby the forked arm connection has two legs with parallel pin holes for admitting the hinge pin, whose inner sides face each other at a distance. The legs (12) are connected at a base (11) and the inner sides of the legs run out to the edge (18) of the leg in each case via a chamfer (17). |
