Device for cleaning surfaces with high pressure water jets

摘要

The device consists of a trolley (10) which supports an arm (12) in a bearing (32). This enables the arm to swing about a horizontal axis and to rotate about a vertical axis. This arm (14) is connected by pivoted links (16,18,20,22,24) to a nozzle (30) which is supplied with high pressure water from a flexible hose. Each pivoted joint is actuated by a hydraulic cylinder to enable the jet of water to be directed onto any part of the surface to be cleaned.
