Lowering Headframe Masts – Latching

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.


Step 1

Latch engages when mobile headframe is raised towards mast head.


Step 2

Once mobile headframe has docked, latch engages, raising a flag confirming to the operator that it’s secure.


Step 3

Mobile headframe is raised to disengage latching, before being lowered to ground level for maintenance.
