Doosan has launched two new-generation six-tonne compact excavators, the new DX62R-3 reduced tail swing (RTS) and DX63-3 conventional tail swing models.
Designed as replacements for the existing DX60R and DX55E machines, the new models incorporate advances in many areas to maximise performance, versatility, operator comfort, durability, ease of maintenance and serviceability with minimum impact on human health and the environment.
One of the stand-out features on the new excavators is the increase in hydraulic performance, which has been boosted with a 33% increase in maximum flow rate to 132 l/min. In addition, the hydraulic system now incorporates a load sensing system which guarantees high hydraulic performance and allows smooth and efficient combined operations. Two-way auxiliary hydraulic flow is also available for the primary auxiliary circuit for operating high flow attachments.
The TRIAS hydraulic system has been heralded as one of the most technologically advanced features incorporated into the design of the Zaxis-5 medium excavator range by Finnish contractor Maaperustus Saarinen Oy.
The Järvenpää-based family-run company, founded in 1990-91, has invested in three generations of Hitachi excavators.
Its current fleet includes a Hitachi ZX50 mini excavator and five Zaxis medium excavators: a ZX135US-3, three ZX225USRLC-3s and a ZX225USRLC-5. The latter was delivered in April this year by Rotator – the Hitachi Construction Machinery (Europe) NV dealer in Finland – and it has been immediately dispatched on the company’s wide range of utility, general and road construction projects.
Work started back in January 2013 deep in the Romont chalk quarry in the east of Belgium. The new EX1900-6 was being put through its paces with Ciment Belge Reuni (CBR).
The Hitachi excavator is the largest of its kind in Belgium, it’s not only helping to enhance productivity on the 30 hectare site, but is also a key part of the company’s environmental efforts.
A rare foray into cranes again here, for one of those jobs that makes me glad that we digger boys don't have to do these sort of things.
The historic town of Carcassone in the south of France is a Unesco world heritage site. It is basically a medieval fort that has change little over the centuries. It’s not the kind of place that you want to be creating any damage. So driving a crane through its streets sounds like a job to be avoided.
Fortunately grutier (‘crane driver’) Fabrice Bresson was up to the task, aided by the compact dimensions of his Liebherr LTC 1045-3.1 and the frantic signalling of the two marshals he brought with him to guide him through the 800-year-old town.
Neil Whatling started his working life at Mirrlees Blackstone as an engineering apprentice at 16 and left with a HNC in mechanical engineering.
In 1987 Neil founded Neil’s Plant. His first machine was a Cat 3C Backhoe Loader, which he operated himself. Expansion followed a few years later when he bought his first tracked machine, a second hand Cat 215 followed by a 428 Backhoe Loader.
