Priority Geotechnical adds an EMCI 4.50 rig to its fleet

In the search for a smaller, more compact rig to add to its fleet, ground investigation contractor, Priority Geotechnical Ltd (PGL), has invested in an EMCI 4.50. PGL was assisted in the purchase of the new EMCI rig by UK-based, ground engineering and rock drilling specialists, Skelair International.

Due to its size, the EMCI 4.50 is adaptable and versatile and is designed for projects with restricted headroom or where mobility is restricted. With its overall height of 3,700mm and a stroke of 2,400mm, the EMCI 4.50 has already proven to be beneficial for PGL's more complex projects.

"We are always working to develop and provide innovative and workable solutions to our clients," said Timothy McGillycuddy, director at Priority Geotechnical. "A lot of the rigs we have in our fleet are larger than 3t and we have been on the lookout for a smaller, adaptable rig for quite some time. The EMCI 4.50, being just 2.7t is easier to transport, and its size helps us to adapt to even the most versatile environments while continuing to maintain performance and function. We have also been very pleased with the post-purchase support provided by both Skelair and EMCI."

Priority recently used the new rig to complete a variety of projects throughout Ireland, including sites on public roads, hospital environments, overwater platforms and in particular, sites with restricted access but very specific project sensitive requirements. Working to minimise disruption and to reduce the overall impact of the geotechnical work, the EMCI 4.50's size and performance has proven to be an invaluable addition to the fleet.

Working at depths in excess of 20m bgl and diameters of 140mm in areas of restricted access where larger rigs would represent potential health and safety risks, the EMCI 4.50's compact size has helped to overcome these challenges. The capability to perform multiple techniques including coring, dynamic and percussive sampling, open-hole drilling and in situ testing, on a single site with an EMCI rig, simplifies day-to-day work arrangements while offering clients greater options.

With less external plant requirements and smaller overall size, the EMCI 4.50 has helped to complete projects with little disruption and at much lower costs - while at the same time helping to safeguard the workforce and reduce the overall footprint of individual jobs and projects.

Steph Keane, sales director at Skelair International, explained: "Understanding the requirements of PGL for a smaller rig that did not compromise on output and was suitable for difficult environments, it was clear that the EMCI 4.50 would be an ideal choice. With a rotary head that has a twin hydraulic motor with a maximum torque of 300daNm and a maximum speed of 480rpm. The 49hp Yanmar diesel engine is more than enough power for the rig's 2,780kg weight - acting as an invaluable enhancement to PGL's existing fleet."
