Abstract (en)
[origin: WO2013092055A2] The invention relates to a handling unit for drill rods, having an elevator bracket (30), which can be pivoted by means of a tilt arm (34) under the influence of a tilt cylinder (32), and means (42) for the detecting a position of the at least one elevator bracket (30). The handling unit comprises at least one valve (50) as means for the position detection of the or each elevator bracket (30) and as part of a hydraulic switching control circuit (54) that continues outside the handling unit and at least one connecting member (52) for the at least one valve (50), which member can be moved by means of a movement of the tilt arm (34), wherein the or each valve (50) opens the hydraulic switching control circuit (54) when the connecting member (52) is in a first position and wherein the or each valve (50) closes the hydraulic switching control circuit (54) when the connecting member (52) is in a second position, such that the state of the switching control circuit (54) can be evaluated as position information.
