Liebherr Piling Rig Hired From Dawson Construction Plant Limited Drives Piles On River Taff Fish Pass

A major piling project on the first phase in constructing the Black Weir Fish Pass on the famous River Taff in Wales presented no problems for specialist piling contractor Thomas Vale Limited, who was tasked with installing 106 SX18 piles by main contractor Carillion. Thomas Vale's Piling Division called on Dawson Construction Plant Limited to provide them with a Liebherr LRB 125 leader piling rig from their comprehensive hire fleet. Thomas Vale chose the LRB 125 because the rigid mast gives accurate driving which provided precise alignment of the piles. Additionally, the powerful 1100H vibrator was more than capable of driving the piles further into the hard ground encountered on the site and this also reduced the need for back driving with an impact hammer. The company reports that the robust and reliable Liebherr rig ensured trouble-free pile driving and the job was successfully completed on time.
Dawson Construction Plant has been a Liebherr partner for around five years and now has a fleet of Liebherr leader rigs for its own international contract piling operations as well as equipment for hire. The company has a long-term plan to add to its piling fleet and replace obsolete equipment with Liebherr rigs until such time as the entire fleet for both contracting and rental is exclusively Liebherr. The latest Liebherr piling rigs to arrive in the Dawson fleet are two LRB 125 XL machines which feature longer leaders than the standard version, providing an effective leader length of 17.5 metres. The operating weight is also greater at 46 tonnes - an additional 3 tonnes over standard models.
Liebherr LRB piling and drilling rigs are designed and built as multi-purpose machines and applications include vibro piling; impact piling; pressing; CFA, Kelly and double rotary drilling; ring vibro and deep soil mixing. There are three classes available - the LRB 125, the LRB 155 and the LRB 255, with operating weights from 40-80 tonnes respectively and with leader lengths from 12.5-30 metres. Engines are all Stage IIIA / Tier 3, which not only produce excellent fuel consumption figures but are also compliant with all the latest noise and exhaust emission reduction requirements. Engine outputs are 450kW on the smallest LRB 125 and 155 models, right up to 670kW for the largest in the available range, the LRB 255, giving power to spare on even the toughest piling tasks.
The LRB pile-driving and drilling range is equipped with Liebherr's tried and tested, high-technology Litronic engine and hydraulics management system and the latest generation CANBUS. Litronic not only contains all the necessary programmes for the various piling procedures but also provides service and trouble-shooting information in a clear and comprehensive format. Process Data Recording (PDE) is available as an optional extra, allowing the machine to continually calculate and store the current working procedures. A GSM modem can be connected to the PDE for remote, long-distance maintenance and process data transmission.
