Abstract

The invention relates to a feed beam, a rock drilling unit and to a method of manufacturing a feed beam. The feed beam (5) comprises a basic profile element (11), which has two or more superimposed material layers (12, 13). At least one of the material layers may be made of composite material.

Description

technical field [0001] The invention relates to a feed beam of a rock drilling unit. The feed beam is an elongate piece that includes support surfaces for supporting and guiding the rock drilling machine. [0002] The invention also relates to a method of manufacturing a feed beam. [0003] The field of the invention is defined more particularly in the preambles of the independent claims. Background technique [0004] Different types of rock drilling equipment are used in mines and other workplaces. The rock drilling equipment is provided with one or more booms, and the rock drilling unit is arranged at the distal end of the booms. The rock drilling unit comprises a feed beam along which the rock drilling rig is configured to move during the drilling process. Modern feed beams are constructed from extruded aluminum profiles which are relatively strong and lightweight. However, current feed beams still appear to contain some disadvantages.
