The Abacus headframe offers flexibility through the opportunity to add a latching mechanism to the headframe, enabling it to be supported while raised and removing strain on the stainless steel cables, for long term benefits.
Latch engages when mobile headframe is raised towards mast head.
Once mobile headframe has docked, latch engages, raising a flag confirming to the operator that it’s secure.
Mobile headframe is raised to disengage latching, before being lowered to ground level for maintenance.
