Abstract
A telescopic crane arm including a boom with a bearing area for a boom extension, a boom extension movable out of and into the bearing area of the boom by travel movements so that a tip of the boom extension protrudes more or less far from the boom. The boom extension has a body at least partially in the form of a hollow profile, and a supply line is configured to simultaneously transmit both electrical energy and data signals. The supply line runs from the boom via the hollow profile of the boom extension to or at least in the vicinity of the tip of the boom extension, and is mounted and configured such that the supply line follows the travel movements. A mechanical tensioning device holds the supply line under mechanical tensile stress during the travel movements.
Claims16
A telescopic crane arm comprising:
- a boom with a bearing area for a boom extension,
- a boom extension configured to be moved out of and into the bearing area of the boom by travel movements, so that a tip of the boom extension protrudes more or less far from the boom, the boom extension having a body at least partially in the form of a hollow profile,
- a supply line configured to simultaneously transmit both electrical energy and data signals, the supply line runs from the boom via the hollow profile of the boom extension to or at least in the vicinity of the tip of the boom extension, and is mounted and configured with such a length that the supply line follows the travel movements, and
- a mechanical tensioning device configured to hold the supply line under mechanical tensile stress during the travel movements.
A crane, in particular a loading crane or forestry crane, comprising:
- at least one telescopic crane arm including:
- a boom with a bearing area for a boom extension,
- a boom extension configured to be moved out of and into the bearing area of the boom by means of travel movements, so that a tip of the boom extension protrudes more or less far from the boom, wherein the boom extension has a body which is at least partially in the form of a hollow profile, and
- a supply line, which is suitable for simultaneously transmitting both electrical energy and data signals, wherein the supply line runs from the boom via the hollow profile of the boom extension to or at least in the vicinity of the tip of the boom extension and is mounted in such a way and designed with such a length that it can follow the travel movements,
- wherein it is preferably provided that the at least one telescopic crane arm is mounted in an articulated manner on at least one further crane arm, and
- a mechanical tensioning device configured to hold the supply line under mechanical tensile stress during the travel movements.
