Definitions

  • cranes which are swivelling and comprise telescopic booms.
  • Cranes are mounted on vehicles, such as trucks, or on other self-propelled machines, such as forwarders. Cranes are used, for example, for loading, and as so-called loader cranes.

  • the control system is typically based on a hydraulic power generation system.
  • the crane typically also comprises outriggers which are connected to the trailer and may be placed in a position where they support and stabilize the crane during its operation.
  • the control system may comprise a control device, by which the operator may remotely control the functions of the crane or its boom, for example in a wireless manner, so that there is no need to provide the trailer with a cabin, a seat, or a station with control devices for the operator.
  • the boom of the crane may consist of one or more boom sections.
  • the end of the boom is equipped with a hook for suspending loads to be transferred, or a tool for transferring loads or objects. It is also possible to connect a man cage or a scaffold to the end of the boom, for a worker.
  • Cranes mounted on vehicles and machines become large, and thereby possibilities to use them in, for example, confined indoor spaces and buildings turn out to be very limited. Also, exhaust gases from the vehicles and machines may pose a problem. It may be difficult to move cranes mounted on trailers manually indoors, and it is not even possible to use a towing vehicle or machine in confined indoor spaces, buildings, or on different floors of a building. Furthermore, bringing a crane mounted on a trailer to the work site may be very difficult or impossible, for example due to the difficult terrain or location of the site.
