New Doosan 34 t Excavators Increase Safety on Aldeburgh Beach

To increase safety for the public, the UK Environment Agency has hired two new Doosan DX340LC-3 Stage IIIB compliant crawler excavators from Lynch Plant Hire to demolish and remove steel box piles, rails and wood that made up old groynes on the beach at Aldeburgh in Suffolk. The new DX340LC-3 excavators from Lynch were supplied by Berkshire-based Promac Solutions Ltd, the authorised Doosan dealer for South East England.

Launched to meet the new Stage IIIB emissions regulations, the new Doosan DX340LC-3 excavators from Lynch are the first in the country. Merrill Lynch, Operations Director at Lynch, said: “Stage IIIB machines are now being specified on many of the projects we are supplying such as Crossrail and the legacy works after the 2012 Olympics. We are investing heavily in new equipment to meet current and future environmental regulations as part of our company mission – ‘Meeting Hire Demands’. This is complemented by the comprehensive training undertaken by Lynch personnel, covering environmental and site-specific inductions as well as that for sector-specific training cards (National Grid, Rail, Thames Water, etc.)”

The Environment Agency team carried out the removal work on the old groynes on a 600 metre section of the beach at Aldeburgh from the Martello Tower to the end of Slaughden Road and removed approximately 20 steel piles and associated debris from the beach. The work involved digging around the redundant piles and pulling them out of the ground and then back-filling with the excavated beach material.

Along with the larger DX380LC-3 Stage IIIB compliant crawler excavator, the DX340LC-3 model features new D-ECOPOWER technology, providing operators with increases in productivity and fuel efficiency, as well as smoother controls. D-ECOPOWER technology utilises an electronic pressure-controlled pump within a closed centre hydraulic system to accomplish increases of up to 26% in productivity and up to 12% fuel consumption improvements, depending on the mode selected.

Owing to the use of a new Doosan Mottrol travel device, the maximum travel speed of the DX340LC-3 excavator has been increased by an impressive 13% to 5.4 km/h and drawbar pull has massively increased by 16% to 32,200 kg, compared to the previous DX340LC model. The swing speed and torque performances have also been boosted by 5% and 7%, respectively, with both the bucket and arm digging forces rising by 5%. These changes ensure outstanding performance on any ground surface and for any work requirement.

The DX340LC-3 excavator is powered by the Doosan DL08K ‘common rail’ 6-cylinder turbocharged diesel engine meeting Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. The engine delivers 202 kW, a 7% increase in power at a low RPM of 1800 compared to the DX340LC.

Like all the equipment in the Lynch fleet, the new Doosan DX340LC-3 excavators are available for hire via the Lynch National Hire Number 0845 400 0000 from the Lynch London ‘super depot’ in North London, the Lynch Midlands depot at Rushden in Northamptonshire and from various satellite depots around the country.

Merrill Lynch added: “Every Lynch machine and attachment goes through an extensive pre-delivery inspection before it arrives on site, ensuring that when it starts to work it is in perfect condition. In order to extend the Lynch health and safety ethos onto every site, a range of extras are available, such as safe-load indicators and height restrictors. This means that all Lynch our machines operate to the very highest health and safety standards.”
