A rigger moves the machine<\/a>. A millwright installs it<\/a>.<\/p>\n\n\n\n That is the functional boundary. Everything else follows from it.<\/p>\n\n\n\n A rigger’s domain is the physical movement of heavy loads \u2014 from their current position to their destination. This includes:<\/p>\n\n\n\n The rigger’s job is complete when the machine is sitting on its new foundation, safely set down, and the rigging hardware has been removed. What happens next is not the rigger’s scope.<\/p>\n\n\n\n Riggers are certified in lifting operations. Their equipment \u2014 every sling, shackle, and hook \u2014 carries a rated working load limit and a current inspection certificate. Every significant lift is preceded by a documented lift plan. The discipline is regulated under lifting equipment legislation in every industrial jurisdiction.<\/p>\n\n\n\n A millwright’s domain begins where the rigger’s ends. Once the machine is on its foundation, the millwright takes over:<\/p>\n\n\n\n The millwright’s job is complete when the machine is mechanically ready for production. Electrical connection is typically a separate scope \u2014 but the millwright ensures the machine is in the correct mechanical condition to receive it.<\/p>\n\n\n\n Millwrights are trade-certified, typically through a four to five year apprenticeship. Their specialist tool set includes laser alignment systems, precision levels, dial gauges, hydraulic torque tools, and bearing installation equipment.<\/p>\n\n\n On a production line relocation, the sequence is consistent regardless of project scale:<\/p>\n\n\n\n Riggers first.<\/strong> Equipment is extracted from its current position using the appropriate lifting method \u2014 hydraulic gantry, crane, or skate system. It is loaded, transported, delivered to the destination, and set down on its new foundation. Riggers manage this entire phase.<\/p>\n\n\n\n Millwrights second.<\/strong> Once equipment is on its foundation, millwrights begin installation \u2014 levelling, aligning, connecting mechanical systems, and commissioning. For a production line with multiple machines, this happens sequentially across the line, with each machine aligned relative to its neighbours before the line is commissioned as a complete system.<\/p>\n\n\n\n The quality of the rigging work<\/a> directly affects the millwright’s task. A machine that has been delivered accurately positioned \u2014 set down level, on its correct foundation marks, without transport damage \u2014 is faster to install and align than one that arrived with problems the millwright now has to correct. On well-managed projects, the rigging and millwright teams communicate throughout, not just at handover.<\/p>\n\n\n\n On smaller projects \u2014 a single machine move within a facility, a light installation with no significant lifting \u2014 it is not unusual for one experienced tradesperson to cover both roles. Millwright training includes rigging fundamentals, and many experienced millwrights are competent at light rigging tasks.<\/p>\n\n\n\n The boundary is defined by the lift itself. As soon as a project involves crane operations, hydraulic gantry work, or any lift where a failure would result in significant equipment damage or personnel risk \u2014 a dedicated qualified rigger is required, regardless of how capable the millwright on site is at general rigging tasks.<\/p>\n\n\n\n
