Abstract (en)
[origin: EP2905421A1] The present disclosure refers to a shearer loader (10) for underground mining. A shearer loader (10) may comprise a mainframe (15) extending in a longitudinal axis and having a first end portion (30) and a second end portion (35) opposite the first end portion (30). A ranging arm (20, 25) may be swivel-mounted at least at one of the first and second end portions (30, 35) of the mainframe (15), the ranging arm (20, 25) being provided with at least one cutting drum (40, 45) pivot-mounted at the ranging arm (20, 25). At least one shearer loader component (100) may be configured to be mounted to the mainframe (15) in a removable manner, but fixedly mounted to the mainframe (15) during operation of the shearer loader (10). At least one bearing unit (115) might be arranged at the mainframe (15) at such a position that the at least one bearing unit (115) supports the at least one shearer loader component (100) when it is moved with respect to the mainframe (15) during assembly or disassembly.
