FIELD: mining, particularly surface drives for rotary drilling.
SUBSTANCE: construction machine comprises pole, working tool carrying skid operated so that skid may slide along front pole side, at least one driving chain for skid moving extending along pole, at least one driving sprocket rotary supported by skid so that the sprocket is brought into engagement with driving chain and at least one driving means for driving sprocket rotation to provide longitudinal skid displacement. Driving chain and driving sprocket are arranged in skid direction opposite to front pole side. At least one driving chain encloses corresponding driving chain at front sprocket side facing from pole to create pressing force directed towards front pole side.
EFFECT: increased reliability and decreased size.
