Doosan in action


Specialist demolition equipment hirer boosts Doosan fleet

Doosan Crawler Excavator DX300LC-3 at work at Demolition Site

JCH Plant Hire Limited, the Coatbridge-based specialist demolition equipment rental company, has taken delivery of a new demolition specification Doosan DX300LC-3 Stage IIIB compliant 30 tonne crawler excavator, purchased from Scotia Plant Ltd, the Authorised Doosan and Bobcat Dealer for the central belt of Scotland.

The new Doosan DX300LC-3 crawler excavator has been put straight to work together with other Doosan excavators and associated equipment in the JCH Plant Hire fleet on a project being carried out by Falkirk-based Masterton Demolition to demolish the former buildings of the Auchmuty High School in Glenrothes. 

Opened in 1957, Auchmuty High School was the first state secondary school in Glenrothes.  The school quickly outgrew the original building and additions were added in about 1970.  Now a new building has been constructed on the old school playing fields as part of Scotland’s school regeneration programme and was completed in the summer in plenty of time for the start of the new school year in September 2013.  The demolition of the old buildings being carried out with equipment from JCH Plant Hire will pave the way for the creation of new playing fields for the pupils at the school. 

With the new DX300LC-3 model on board, the JCH Plant Hire fleet now includes four demolition specification Doosan crawler excavators and a Doosan DL300 wheel loader for use on demolition projects throughout Scotland.  The other Doosan excavators in the fleet include a 25 tonne DX255LC excavator and two 35 tonne DX340LC models, one a long arm version and the other a standard arm excavator.  The equipment in the JCH Plant Hire fleet is available for rental by demolition contractors working across Scotland.

Robust Machines, Low Running Costs

Company Owner, James Currie, commented: “We formed the business over 18 years ago and over that time we have built up substantial expertise and experience in supplying a full range of hire equipment for demolition contractors.  I have been purchasing Doosan excavators for more than 10 years and have found them to be very robust for the demanding work on demolition sites, as well as offering lower running costs.” 

Like all other excavators in the Doosan range, the new DX300LC-3 model is a dependable, high performance machine.  It is powered by the Doosan DL08K ‘common rail’ 6-cylinder turbocharged diesel engine meeting Stage IIIB emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies.  At 159 kW, the Doosan DL08K engine in the DX300LC-3 excavator delivers 2% more power at a lower speed of 1800 rpm than the existing DX300LC Stage IIIA model.  Factory tests show a 5 to 10% reduction in fuel consumption, depending on the operating mode selected and the work being done. 

A new ECO Gauge on the control panel helps the operator to lower fuel consumption by providing real time monitoring of fuel rate and actual engine-percent load.  Two new operating modes (P+ mode: Power Plus and L: Lifting) improve controllability and efficiency. 

Workload/hour outputs have increased by an average of 6% across the different power modes in the DX300LC-3.  In the DX300LC-3, a new travel device has increased the maximum travel speed to 5.3 km/h, while the drawbar pull is increased by 4% to 29,800 kg and lifting capacities have been increased by 6%.

New hydraulic pumps and valves increase hydraulic flow by up to 11% and pressure (350-370 bar) to boost front, travel and power functions as well as increase lifting capabilities and reduce cycle times.  Overall, the new hydraulic system improves the productivity of the machine through highly responsive controls. 

The new ROPS and OPG certified cab offers more space (+6%) for the operator and several convenient features, including direct control through the joysticks, which have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments.  A new high-quality, heated air suspension seat reduces operator fatigue, while a new cab suspension system helps to cut vibration by 20% and reduce the sound level in the cab to 71 dBA.  

To support both Doosan and Bobcat products, Scotia Plant offers a large selection of genuine accessories and parts.  The company carries most essential spare parts and provides a back-up service with rapid delivery for other items. 

Customers benefit from the company’s on-site service network, covering everything from emergency repairs to routine maintenance.  The company’s trained engineers have years of experience of repairs and servicing of heavy plant and machinery and the company’s service vans are fully equipped with workshop tools and parts for on-the-spot service work.
