Hydraulic robot jet lance
First Claim
1. Jet lance device comprising a hydraulic crane with an articulated jib, said articulated jib having a plurality of rotatably connected arm parts movable by hydraulic motors whereby said arm parts rotate about horizontal rotational axes, said articulated jib having one end connected to the crane and a free end opposite the end connected to the crane, a hydraulic rotator mounted on said free end of said jib such that a rotatable support element thereof is turnable about a rotational axis extending vertically through said jib, and a jet member mounted on the support element, which jet member comprises a jet lance, and pivoting means connected to said jet lance for pivoting the jet lance on a pivot axis transversely of said rotational axis of the rotator and said jet lance connected to a source of jet liquid under high pressure, and wherein the device further comprises control and drive means for operating said jib, rotator, and pivoting means.

Abstract
A jet lance device comprising a hydraulic crane with an articulated jib movable by hydraulic motors, a hydraulic rotator mounted on the free end of the jib such that a rotatable support element thereof is turnable about an axis in the vertical plane through the jib, and a jet member mounted on the support element. This jet member comprises a jet lance which is pivotable on a pivot axis transverely of the rotation axis of the rotator and connectable to a source of jet liquid under high pressure, and the device further comprises controllers and drivers for operating the device.
