Stabilisation to the
Dawson-WAM have just completed emergency
slip repairs to the M25 Motorway between
Junction 26 and Junction 25. These emergency
works were completed for Jackson Frameworks
over a series of night possessions.
Due to the significance of potential impact
to the M25 all equipment had to be mobilised
to site, rigged up, complete the allotted works, derigged
and demobilised each and every night during the works.
With an operating window of midnight to 4 a.m this
meant that the actual working window was only 1 to 1.5
hours per night.
An 80 t ABI TM22 with 30VV vibro hammer initially
installed 9 m long sacrificial sheets to support the car-
riageway and then installed 18 m long AZ38 pairs assisted
by a 70 t telescopic crawler crane.
The 70 t crane was then used to support an impact
hammer to backdrive the sheet piles.
The final works involved the use of the 70 t crane to
support a suspended vibro hammer to install some 6 m
long AZ18-700 sections down the embankment slope
to act as isolated pinning piles.For further information:
Tadano in Port Talbot with Davies crane
The Tadano telescopic ATF 400 mobile crane from Davies
Crane Hire, carried out a special job at the TATA Steel
plant, in Port Talbot, South Wales.
The requirements for this job included fast set-up
times, manoeuvring heavy loads with great precision
and working safely at night with low visibility.
The crane was used to remove and replace 2 x 45 m
conveyors, which transported the shipped coke straight
from the vessels to the blast furnaces. Throughout the
project, the steel production facilities had to remain fully
operational, which meant that most of the work had to
be completed at night.
The Tadano was used to lift the 3 x 15 meter long
sections, weighing 18 tons each, to heights of 40 meters.
During this process the Tadano ‘Lift & Release’ system
played a vital role in safely manoeuvring the sections
– especially where obstacles restricted the view for the
This prevents loads swinging out and thus provides
an additional safety measure for staff working on the
site and for loads being lifted.
The crane operator chose to activate this feature and
used the high intensity xenon boom lights for optimal
night time visibility.
The strong and rigid Tadano boom meant that the
plete lift was carried out with the main
boom and a 36.5 meters luffing jib. A
Tadano ATF 50G-3 mobile crane was
used to rig the luffing jib.
Tadano´s two engine concept kept
the on-site emissions to a minimum dur-
ing the job, complying with TATA Steel´s
sustainability policy. It also meant that
fuel consumption was lower making
this lift profitable, efficient, fast and
