Doosan Construction Equipment will be showing new products from the company’s Doosan Heavy, Bobcat and Doosan Portable Power ranges for the first time at the Plantworx 2015 Exhibition being held in the UK from 2-4 June 2015 at Bruntingthorpe Aerodrome in Leicestershire.
This will be first appearance in the UK of the new Doosan ‘-5’ ranges of crawler and wheeled excavators, wheel loaders and articulated dump trucks (ADTs) meeting the latest Stage IV emission regulations. Several Bobcat products will also be shown for the first time, including the new S450 skid-steer loader, the new E17 to E20 1-2 t compact excavators and new Bobcat telehandlers. The stand display will be completed by new generators and compressors from Doosan Portable Power, including several new Stage IIIA, Stage IIIB and Stage IV compliant models.
New Generation Stage IV Machines
Doosan has just launched nine new Stage IV compliant crawler excavators from the 22 tonne DX235NLC-5 to the 52 tonne DX530LC-5 models, as well as the new DX170W-5 and DX210W-5 wheeled excavators. All of the new models, of which several will be on show and working at Plantworx, offer enhanced comfort and controllability together with new features to boost uptime and return on investment, with a focus on increased power, robustness and agility. These advances are marked by a distinctive new machine styling scheme for all LC-5 machines.
The Plantworx stand will also feature the new high performance DL300-5 to DL550-5 Stage IV wheel loaders from Doosan, replacing the successful Stage IIIB loaders launched in 2012. Providing another leap forward in wheel loader design again represented by new external styling, the DL-5 range offers increased productivity and fuel economy, with features such as a new high comfort cab, powerful Scania Stage IV engines, smooth and responsive hydraulics, a ZF powertrain, axle cooling and auxiliary hydraulic connections.
Like the new generation Doosan excavators and wheel loaders, the DA30-5 and DA40-5 Stage IV ADTs go far beyond just meeting the latest emission standards and incorporate many additional features and product improvements to establish a new benchmark in load carrying performance, fuel efficiency, enhanced controllability and high operator comfort, together with improved reliability, durability and reduced maintenance and servicing costs.
Common to all these Stage IV machines from Doosan is the new factory-installed CoreTMS state-of-the-art wireless fleet monitoring system, a tool designed specifically for the Doosan range, providing comprehensive information about machine performance in a dual mode (satellite, GSM). At the heart of all the new Stage IV machines are Doosan or Scania water-cooled diesel engines which offer convenience and lower costs by meeting Stage IV emission regulations without the need for a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.
The new generation S450 skid-steer loader from Bobcat builds on the success of the S130 model it replaces, by combining the advantages offered by a truly compact loader with many of the new features and improvements found on the larger Bobcat new generation models. As well as its compactness, the S450 skid-steer loader can be supplied with a comprehensive choice of 48 different product families of Bobcat attachments (with more to come), offering solutions for a very wide range of applications and providing a perfect illustration of the Bobcat Tool Carrier concept common to all Bobcat compact loaders.
Fully Pressurised Cab Option
Like the larger loader models, the S450 skid-steer loader offers significantly improved comfort and visibility to allow for greater control and accuracy in tight working spaces. In addition, for the first time in a skid-steer loader model in this size class, the S450 loader is supplied with a fully pressurised cab with air-conditioning as an option. Other key features include increased hydraulic performance and efficiency; a new tailgate design; integrated rear bumper and enhanced serviceability.
The new generation E17, E19 and E20 1-2 tonne excavator models from Bobcat provide an unmatched combination of class-leading breakout forces, working range, smoothness of workgroup functions, hydraulic output and fast cycle times, centred around a roomy and comfortable operator environment, durability and excellent service access. The new models are towable on trailers for up to 2000 kg, with transportability further enhanced by new tie-down points. An expandable undercarriage, automatic slew brake and advanced diagnostics and instrumentation are just some of the many standard features included on all three excavators.
Alongside the Bobcat compact loaders and excavators at Plantworx, the company will be focusing on the latest developments in the Bobcat range of telehandlers. These include the new 13 m and 14 m lift height T35130S and T35140S telehandlers aimed particularly at the rental industry. The new T35105, T35105L and T36120SL 10-12 m middle lift telescopic handlers have replaced the previous five models from the T35100 to the T35120SL telescopic handlers and at the other end of the range, the new TL358 model is 6 m lift height compact telehandler, available with two rated capacities of 2.6 or 3 tonne.
New Doosan Generators and Compressors
Among the new Doosan Portable Power products being featured for the first time at Plantworx are the Stage IIIA compliant G40-IIIA and G60-IIIA generators and the new Stage IIIA compliant 7/53, Stage IV compliant 12/154 and 12/254 and 7/125-10/110 Stage IIIB Dual Mode portable compressors.
Providing 40 kVA and 60 kVA prime power, respectively, the G40-IIIA and G60-IIIA models are part of the new platform of generators from Doosan and share a common design with the G80-IIIA to G200-IIIA models launched over the last two years. The Yanmar-powered G40-IIIA and John Deere-powered G60-IIIA generators are both available with electronic speed regulation (optional on the G60-IIIA model) providing, in addition to stability and better load take-over capabilities, a flexible dual frequency 50/60Hz working mode (optional for both models).
The new 7/53 portable compressor is a 36 kW Stage IIIA compliant replacement for the 7/51 model and has been redesigned to allow Doosan to keep this model in the Stage IIIA category, avoiding the need to transition to meet Stage IIIB regulations. The new features on the 7/53 portable compressor include forklift slots and a new bunded base option.
The largest single axle model from Doosan, the new 12/154 compressor is the Stage IV successor to the previous 12/150 model and is again powered by the Cummins QSB6.7 6-cylinder diesel engine and meets Stage IV regulations without the need for a diesel particulate filter (DPF).
Also meeting Stage IV emission standards, the new 12/254 compressor is powered by the 247 kW Cummins QSL9 diesel engine meeting the regulations without the need for a DPF. The 12/254 model again offers both compact size and easy serviceability for added value performance. Several additional features such as multiple air outlets, a 110% bunded base, central drains and forklift slots have also been incorporated as standard in the 12/254 compressor.
New ‘Dual Mode’ Feature Increases Flexibility
The 7/125-10/110 Stage IIIB model has a new ‘Dual Mode’ feature as standard, with a choice of two pressure and flow ratings on the same machine. By pushing a button on the keypad, the operator can switch between ‘LO’ (low pressure mode: rated pressure 6.9 bar/free air delivery 12 m³/min) and ‘HI’ (high pressure mode: rated pressure 10.3 bar/free air delivery 10.6 m³/min). This ‘two-for-one’ solution replaces the need to choose between different models as used to happen in the past and offers much greater operational flexibility from the same machine.
The new 7/125-10/110 portable compressor is powered by the Stage IIIB Cummins QSB 4.5 water-cooled diesel engine providing 97 kW of power and meeting emission regulations through the use of cooled exhaust gas recirculation (EGR) and diesel oxidation catalyst (DOC) after-treatment technologies, without the need for a DPF.
