Tritech takes delivery of BSP's first radio controlled piling rig

tritech ground engineering has taken delivery of the uk’s first radio controlled bsp jx 8

Tritech Ground Engineering has taken delivery of the first radio-controlled BSP JX-8 piling rig mounted on a low ground pressure JCB JS200 crawler carrier.

The latest addition to the fleet of piling equipment has been specifically designed to offer highest capacity/lowest ground pressure combinations anywhere in the UK, according to the firm.

For piled foundations that require a detailed engineered piling mat to be placed around the area to be piled, Facilitating this work can involve large amounts of material either being brought into site or existing material being engineered to a specific weight bearing design in order to carry the piling rig.

The new rig has been built to use the minimum requirements for heavily engineered piling mats. Already operating an earlier JX8 rig, Tritech operations manager Karl Amos looked at tweaking the new arrival’s design to make it more productive and easier in operation.

Mounted on a JCB JS200 carrier, the piling equipment is a collaboration between Colets Piling and BSP and comprises a 12.5m single mast and BSP DX25 hydraulically accelerated drop hammer.

The piling equipment comprises a fixed 12.5m boom capable of handling piles of up to 8m in length and a primary braked winch carries the 4.5t piling hammer whilst a secondary winch is used to handle the piles. This version of the rig incorporates a mast foot and pile guide, a very useful addition according to Karl. The BSP DX25 hammer is an ideal tool for this sort of work combining a robust build with productivity unsurpassed for its size.

Requiring 150l per minute of oil flow at 160bar, the hammer can deliver up to 25kNm at 60 blows per minute. This performance far exceeds the requirement on most projects for concrete driven piles resulting in the machine working at just 25% power for fear of damaging the pile tops.

The combined weight of the rig is just over 27t and this light weight, combined with a wide and long undercarriage reduces the ground pressure imposed by the machine to just 82kN/m2 without a pile. The design of the rig means that the weight of the outfit is only increased when a pile is lifted into position and reduces again as the weight of the hammer is carried through the pile once it is located in the driving position.

One of the first projects for the new rig was in Formby where Tritech had been engaged to drive almost 450, 150mm concrete piles for a new housing development. Working for the ground work sub-contractor, Tritech was able to mobilise the new outfit quickly thanks to the reduction in engineering works prior to the company starting on site.

“The standard cab view can be limiting for the operator, said Amos. “The operator, can now be on the ground, in full control and not need the constant attention of his assistant at all times. This again makes us safer and more productive.”
