GRAPPLING WITH A SCREW PILE

Screw piles aren't your standard foundation, and their installation is quite different from other piling types.

Instead of big fixed mast drilling rigs or cranes with drop hammers that require large platforms and make lots of noise - screw piling simply uses two excavators of varying sizes:
- The "1st" excavator - is there to drill the screw pile into the ground. It is typically larger excavator between 12T and 50T so as to power the powerhead.
- The "2nd" excavator is there to help keep the 1st excavator moving. Typically a 6T to 20T excavator with a grapple attachment.

So whilst the the “1st” rig is the flagship glory hogging powerhouse that ensures the screw pile will get the load it is designed to take - the smaller humbler 2nd rig with it's grapple attachment is the workhorse that toils in the background and keeps the site moving.  It performs tasks such as getting piles unpacked after delivery, putting the right pile next to where it should be installed, getting extension pipe into position to splice to the pile, help to
cut piles to height, and generally tidy the site up.
