摘要： The present disclosure relates to a plow guide assembly for guiding a mining plow. The plow guide assembly may comprise a base member including a first guide beam for guideing the mining plow and extending along a first axis, and a second guide beam spaced apart the first guide beam for defining a service clearance therebetween, and extending along a second axis axially aligned to the first axis. The plow guide assembly may further comprise an insert element insertable into the service clearance and having a third guide beam extending along a third axis. In an assembled state of the insert element, the third axis is axially aligned to the first and second axes.

摘要： A plow bit for a bit holder including a recess of a mining plow is disclosed. The plow bit also has a bit shank configured to be inserted into the recess of the bit holder. The bit shank has a front shank face, which is concave. The bit shank also has a rear shank face disposed on an opposite side of the bit shank with respect to the front shank face. The bit shank further has a first lateral shank face connected to the front shank face and the rear shank face. The first lateral shank face includes a first groove extending from the front shank face in direction of the rear shank face. The groove receives a securing pin.
