One of our 80t ABI TM22s working on the M4 with Steel mat hire steel mats spreading the load of the rig to platform below. On this particular part of the site there is a narrow working corridor with a short distance between live carriageway and sheet pile line. The mats reduced the bearing pressure and transferred it lower into the ground meaning that our client did not have to place platform material out to the boundary line.
The rig is positioned to deliver maximum installation energy into the piles and to prevent the ballast weight encroaching on the safety zone to the live traffic. Piles were installed to level with a powerful rig mounted vibro hammer without the need to impact drive.
