Definitions

  • the present invention relates to the field of lifting equipment and cranes used for lifting and loading within the transportation industry, energy industry, process industry and manufacturing industry, and more particularly to a hose guard for an articulating crane and to an articulating arm arrangement of an articulating crane.
  • a crane is generally defined as a machine for lifting and moving heavy objects by means of ropes or cables suspended from a movable arm.
  • One of the most common crane types is an articulating crane.
  • Articulating cranes are special type of jib cranes having an articulating arm jib or boom. Articulating cranes are also often referred to as loader cranes or knuckle-boom cranes.
  • An articulating crane has typically a hydraulically-powered articulated arm arrangement having one or more of the boom sections telescopic.
  • Articulating cranes are used in industry for different applications these including handling of bulk material, such as coal, mineral, scrap metal and other material within the process and manufacturing industry as well as within the energy industry. Articulating cranes are also typically used within the transportation industry as loading and unloading material these including loading and unloading of timber, bulk material, scrap metal and other material.
  • the articulating crane may also be a mobile crane or a truck-mounted crane.
  • a truck-mounted articulating crane is often a crane in which the numerous telescopic boom sections may be folded into a small space when the crane is not in use.
  • Within forestry articulating cranes are used in e.g. forwarders and timber trucks for loading and unloading of timber.
  • Some of the typical articulating cranes according to the prior art are designed to have the hydraulic hoses and pipes fitted inside the articulated arm and the telescopic end-side inner boom portion of the articulating crane.
  • Two typical examples of this type of articulating cranes according to the prior art may be seen in US Patent documents US 5,924,837 and US 6,530,742 B2 .
