Coates Hire has launched a new shoring solution: the MP250 hydraulic strut — the largest proprietary shoring prop available in the Southern Hemisphere.
Following on from the highly successful launch of the MP150 hydraulic shoring prop, Coates Hire has recently introduced the MP250, a 250 tonne capacity hydraulic shoring prop.
The MP250 is designed to provide direct support between concrete capping beams in basement type excavations, however, it can be used to span steel section waler beams with appropriate bearing checks.
Individual struts can also be fitted with Coates Hire’s wireless, fully automated load monitoring system.
According to Nigel Robbins, Coates Hire National Sales Engineer, during the recent construction of a residential block car park basement the piled walls of the basement at one end of the excavation were beginning to rotate, with the potential for failure.
He says the engineering team at Coates Hire was called to see if they could provide a solution to arrest any further movement of the wall and with time being critical they set about providing a comprehensive technical solution to prop the walls using the latest MP250 which could span the distance of 23.2 metres across the site to prop off the opposite wall.
“A design was quickly submitted and approved and within three days the equipment was supplied and installed under the full supervision of the engineering team at Coates Hire. As part of the installation process the props are hydraulically jacked out using a small petrol shoring pump and are pre-stressed as part of the installation process. This puts support back into the walls and limits any deflections down to an absolute minimum. Once jacked out to 1200Psi the hydraulics are locked off and the prop is safely installed.”
Robbins says six of the MP250 props were installed in less than one day and the emergency make-safe project was successfully completed to the satisfaction of the main contractor and his client.
“The speed at which the Coates Hire team responded was highlighted as a huge positive, as was the speed of installation and extraction process. Coates Hire also incorporated the latest technology prop load monitoring system into each prop to allow the full monitoring of the loads inside the props during the remainder of the excavation works.
“This unique technology provides peace of mind and contributes to the overall safety package that Coates Hire can now offer its customers,” he says.
Traditionally excavations have been supported by the use of tie back solutions but more often, due to next door properties having similar basement construction, the use of tie back (anchor) solutions is regularly being refused.
Robbins says the introduction of the high capacity hydraulic shoring props by Coates Hire has provided an alternative go-to solution for the Australian construction and building industry.
“With the support of an experienced design and engineering team providing comprehensive support solutions, Coates Hire is enabling its customers to remain on time and within budgets while at the same time providing the safest of working environments for their employees,” he concludes.
