Telescopic Leader Rig Installation

Sheet Piling (UK) Ltd own and operate a comprehensive fleet of modern Telescopic Leader Rigs which can be fitted with a range of attachments to ensure optimum performance and safety is achieved during pile installation and extraction.

The multifunctional Telescopic Leader mast provides support for all attachments required for pile driving, extracting, augering and static pile pressing operations, thus eliminating the requirement for traditional temporary works. In addition, the rigs have very low set up times (less than 30mins from transport to operation configuration), vibrators and other attachments can be connected and disconnected using a quick and safe docking system; and the tracked carrier system offers high mobility on all construction sites.

For all types of pile driving and extraction works, Sheet Piling (UK) Ltd are able to offer the following plant.

ABI RE12/15 Mobilram-System Leader Rig with 60Te high frequency vibratory hammer.
ABI TM12/15 Mobilram-System Leader Rig with 60Te variable moment vibratory hammer.
Bauer RTG RG16T Telescopic Leader Rig with 100Te resonance free vibratory hammer.
Bauer RTG RG18T Telescopic Leader Rig with 90Te resonance free vibratory hammer.

The very latest 'resonance free' or 'variable moment' vibratory hammer ensure that vibration oscillations are reduced to a minimum by adjusting the eccentric weights when driving through the natural frequencies of the soil. Consequently, consideration can be given to vibratory pile installation and extraction using these hammers where previously the high frequency vibrations generated on start up and shut down would preclude the method.

In addition to the vibratory hammers, Sheet Piling (UK) Ltd can offer the following attachments to the telescopic leader:

Auger drive motor to carry out preaugering in advance of pile installation to allow loosening of the soils and enable piles to be driven into ground which otherwise might not be suitable for a sheet pile solution or would require a uneconomically heavy pile section.
Impact hammer to allow backdriving of piles to final level with the benefit of short leg guides which avoids deep lead trenches required for crane suspended impact hammers.
Hydro press system which allows vibration-free and low noise installation and extraction of sheet piles in sensitive locations particularly close to existing structures. The Hydro press drives up to 4 single piles into the ground during any set up and both 'U' and 'Z' shaped piles can be installed.

In summary, Sheet Piling (UK) Ltd can off a full range of modern telescopic leader rig and associated attachments to carry out piling works in almost any ground conditions or location.

Key Benefits and Advantages
