Digga does the job for TXM

By Digger Blogger | 15:32 BST, Wednesday, 31 July 2013 | 0 Comments

Augers look set to take over from buckets on Network Rail electrification projects.

TXM Plant is erecting stanchions for overhead cabling on the Manchester-Liverpool railway line. It needs to make holes three metres deep by a metre wide, into which the concrete foundations are then poured. It started out by experimenting with a mix of hydraulic breakers, rock wheels and clamshell buckets. This worked just about well enough, more or less, but it proved to be slow and expensive work. There had to be a better way.

And there was...

Better the devil you know, says Barry

By Digger Blogger | 10:02 BST, Tuesday, 30 July 2013 | 0 Comments

Barry Walsh has been in touch from Youghal in County Cork to tell us about his new JCB. It is the first JS145 LC with the new engine to be sold in Ireland.

Barry – that’s him above on the on the right – set up Barry Walsh Civil Engineering Ltd eight years ago. His work is varied from proper construction stuff like excavation, drainage and general groundworks to sports pitches and golf course construction.

The guy on the left, by the way, is Conor O'Lomasney from the local dealer, ECI JCB Cork.

Brenchley’s sucker punch

By Digger Blogger | 13:53 BST, Friday, 26 July 2013 | 0 Comments

While we like our diggers round these parts, we do recognise that digging is not the only way to excavate. You can suck too, as Brenchley Civil Engineering has discovered.

Brenchley is the first company in the UK to take delivery of the new TT-UK/RSP compact 7.5-tonne City Sucker.

The Portsmouth-based contractor has a street lighting replacement contract for Southern Electric in Hampshire and West Sussex. It has been using a number of larger suction excavators over the past couple of years on this assignment, because digging down on live cables is rather dangerous. Brenchley’s risk assessment calculated that by using suction excavation, their strike rate fell from one in every 142 mains/disconnection holes dug by traditional means (hand or small tools) to one in 546 holes using suction excavation.

Two new-generation six-tonne compact excavators from Doosan

By Digger Blogger | 09:09 BST, Friday, 26 July 2013 | 0 Comments

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.

TRIAS hydraulic system gains family approval

By Digger Blogger | 16:30 BST, Wednesday, 24 July 2013 | 0 Comments

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.
