On 11th April 2017 Liebherr delivered its 50,000th wheeled loader – providing a good excuse for a retrospective.
Hans Liebherr is most famously associated with the early development of self-erecting mobile tower cranes, with his first machine, the TK10, in 1949 but it wasn’t long before he was making excavators and loaders, and by as early as 1955 he had diversified into domestic refrigerators.
The very first Liebherr wheeled loader was the Elephant Type 90 (pictured above), designed and built as a prototype in Kirchdorf, Germany in 1954. It had a bucket volume of 1.25 m³, a 66 kW (90 HP) engine output and an operating weight of 12,000 kg. To steer, both pairs of wheels were braked in opposing directions, like on a skid-steer loader. However, the Elephant never went into series production and acted only as a test unit for further development. The Liebherr engineers developed a second, larger variant alongside the test vehicle, the Mammoth 90.
DDS Demolition is using a trio of heavy-duty breakers to destroy reinforced concrete structures during a rebar mill clear-up at Sheerness Steel works on the Isle of Sheppey in Kent.
The breakers, supplied by Sandhurst, are Atlas Copco HB2200, HB3600 and HB4200 units. These immensely powerful breakers weighing two, three and four tonnes respectively were purchased to suit DDS Komatsu excavators working on the site: PC290, PC350, PC360, PC450 and a PC490.
DDS Dmolition, of Manston in East Kent, has a £3m contract for the Peel Port Wellmarsh tear-down and site clear-up, which is expected to take 52 weeks.
In Greek mythology, the Minotaur had the head of a bull and the body of a man. At Case Construction Equipment it has the head of a bulldozer and the body of a compact tracked loader.
The DL450 compact dozer loader, also known as Project Minotaur, was launched as a concept machine by Case Construction Equipment at Conexpo 2017 in Las Vegas in March.
Case says it is the industry’s first fully integrated compact dozer loader and it has more than 30 new patents pending for it.
Specialist vessels have started to arrive at the Port of Dover for harbour dredging works on the £250m Dover Western Docks Revival (DWDR) development.
Main contractor for the project, which is designed to enhance port capacity and kick-start local regeneration, is a joint venture between VolkerStevin and Boskalis Westminster – VSBW. Various items of floating equipment has begun arriving in Dover to undertake initial harbour dredging to remove soft sediment. Up to 20 different VSBW vessels over the next eight weeks as it enters the harbour dredging phase this month prior to the start of piling.
The first vessel to arrive was the Kreeft, a self-propelled crane barge which is fitted with bespoke attachments for identifying and removing obstructions.
A PD screening bucket has solved a problem for a customer needing to process pulverised fuel ash (PFA) at a power station.
For more than 40 years PFA from the power station has been sent to landfill. As the material is very fine it needs 12-14% of moisture adding to it so it doesn’t blow away. This means it is conditioned with water to stay on the floor.
Logistics firm Hargreaves Services, whose roots are in the coal industry, wanted to recycle some of the landfilled PFA. The material it wanted to process was nine years old so had settled firmly into place. They had started reclaiming the old PFA and bulldozing it up. This unfortunately meant that much of it was in big boulders of 10-20mm in size. They needed it shredded down to 15mm for the use they had planned for it.
