Pactronic proves itself in Bavarian quarry

Digger Blogger | 11:36, Mon April 20 2015 | 0 Comments

Some readers may recall my post here about the Liebherr HS 8300 HD Hybrid Drive duty-cycle crane when it was launched two years ago at Bauma 2013. Well, I now have more news. The first unit is finally at work on site.

The stand-out feature of this machine is the Pactronic hydraulics system first seen on Liebherr Nenzing’s harbour cranes but not previously in the construction sector.

A large cylinder running along the side of the carbody is an hydraulic accumulator that collects hydraulic power every time the load is lowered – although you can't see it in the photo above; it's on the other side. Surplus energy is stored and subsequently regenerated, thus increasing the material handling capacity while at the same time reducing fuel consumption.

Accolade for Liebherr excavator designers

Digger Blogger | 15:59, Wed April 15 2015 | 0 Comments

Liebherr’s R926 Compact crawler excavator is among this year's winners of the famous Red Dot Awards for Product Design.

This machine is one of 81 Red Dot winners this year out of a total of 4,928 entries.

Liebherr launched the R926 Compact crawler excavator last year to replace the R924. It weighs approximately 25 tonnes and combines the properties of a standard crawler excavator, such as high performance and versatility, with the advantages of compact machine, Liebherr says. With its compact dimensions, it is well suited for urban deployment. Thanks to the wide scope of equipment and options, it can be configured for all earthmoving, deep foundation and demolition tasks.

Hard graft at Comrie colliery

Digger Blogger | 09:21, Wed March 25 2015 | 0 Comments

Hyundai machines have clock up 40,000 hours at a Scottish colliery and are still going strong.

Land Engineering Services (LES), based in West Yorkshire, is a mining, earthmoving and remediation company that operates throughout the UK.  The company won the tender in 2012 to ‘clear’ a contaminated colliery in Scotland.  LES invested in five Hyundai machines purchased from Derbyshire based Hyundai dealer, EP Industries, to help complete the task.

The former Comrie colliery site is recognised as the largest area of post-industrial dereliction in West Fife. When Land Engineering Services (LES) began working on the site in 2011 it was a combination of contaminated land, large areas of hard standing, associated with the former colliery pit head area, and a 40-metre high burning colliery waste tip (called a bing, apparently). Mor than 100 hectares of countryside were unfit for any conventional countryside use.

JCB set-up wins over Brett

Digger Blogger | 13:23, Tue March 24 2015 | 0 Comments

Brett Concrete has an annual production capacity in excess of 500,000 cubic metres but has not always felt well served by its equipment suppliers. It seems happy with JCB though.

Brett Concrete, part of the wider Brett Group, originally bought a JCB 427 shovel for handling concrete at its Royal Tunbridge Wells site. The company has been sufficiently impressed with the performance of the machine that it has now bought a second model to work at its Canterbury site.

Brett uses both machines to move fine and coarse aggregate from bays into steel bins and trucks as part of the concrete production process. Operating in short bursts each machine is going to be handling between 40,000 and 50,000 tonnes per year.
