At the beginning of August, two WWTECH engineers started works to create a new slot in the break shaft of the gantry crane’s drum. Originally, the existing groove was to be enlarged, however, it was used and a decision was made to execute a new one – nominal one.

The machine used for this task – KM300, tool – three-plate finger cutter.

Although the working conditions were hard (high temperature, dust, noise, height 30m) everything was done within 5 hours and the achieved tolerance was 0.03 mm.
