By Mark S. Kuhar

A total of more than 17,000 visitors attended Hillhead 2012 in Buxton, England, compared with 15,500 in 2010, a growth of approximately 10 percent. Throughout the three days of the show they experienced more live demonstrations and new plant equipment than ever before, presented by a record 459 exhibitors.

Hillhead is the UK's major construction event and the biggest working quarry show anywhere in the world. Rock Products’ Editor Mark Kuhar reported live from the show, the only U.S. aggregates industry editor in attendance.

“We’re very pleased with the number of exhibitors and attendees,” said Richard Bradbury, commercial director, at a dinner of international editors. “The weather really cooperated for us, and those I have spoken with are finding the show to be a valuable experience.”

Hillhead was established in 1982. The first event at Hillhead Quarry took place in 1983 and has been held there every two years ever since.

There were three categories of working demonstration areas:

  • Quarry face: large wheel loaders and excavators load dump trucks from a 10,000-ton rock pile and hydraulic breakers are used for secondary breaking.
  • Rock Processing: a wide variety of screens and crushers are used to process material into single-size or graded products.
  • Recycling: well over 1,000 tons of waste material is sorted, crushed, shredded, screened, and stockpiled into reusable aggregate or waste material.

The show is organized by Nottingham-based QMJ Publishing Ltd, magazine publishers and exhibition organizers for the quarrying, natural stone and associated industries.

Following are some of the products that made waves at the show:

Komatsu Hybrid HB215LC-1 Hydraulic Excavator
Marubeni-Komatsu Ltd announces the first commercial availability of hybrid technology for the UK construction machinery market. The HB215LC-1 replaces the PC200-8 Hybrid, which was showcased at BAUMA 2010. With an operating weight of 21.220 kg and bucket sizes ranging from 0.8 cu. m to 1.05 cu. m, the HB215LC-1 fits into the large 21-ton class of hydraulic excavators.

The HB215LC-1 is a second-generation hybrid machine and a product of ground-breaking research going back to the beginning of this millennium when Komatsu decided to develop hybrid technology for construction machinery to a level compatible with full-scale serial production.

Together, the 900 Komatsu hybrid machines currently owned by customers in Japan, China and the United States log more than one million hours of field operation. Komatsu has now further refined its exclusive hybrid technology and continues to strengthen its leadership in innovation in the construction equipment with the even more efficient HB215LC-1 and its enhanced hybrid components.

Looking ahead, Komatsu plans to expand its hybrid technologies to larger excavator models and construction equipment other than hydraulic excavators. Komatsu will continue to introduce new equipment that is specifically designed to curb environmental impact on the natural environment of planet earth, thereby meeting the requirements of the times, the company says.

Sandvik CI511
Sandvik launched its second generation of compact horizontal impact (HSI) crushers and the CI511/512 crusher combines the ability to configure one base crusher into either a primary or a secondary configuration, according to the company. Sandvik said the new HSI crusher possessed a revolutionary chamber design resulting in greater reduction ratios.

Sandvik said the crusher was able to produce products with two curtains, while other machines often require three-curtain crushers to produce the same. The CI511/512 is equipped with an infinite hydraulic curtain adjustment combined with a brake-positioning system relieving pressure and setting when uncrushable objects enter the machine. Sandvik said that no hydraulic power was required during normal operation, saving on operating power and reducing total power consumption.

Rammer Hammers Return
Rammer hydraulic hammers and attachments returned to the marketplace via Hillhead after a five-year brand absence with a display that reinforces the company’s reputation as an innovator. Although the company’s products have been on display under the brand of parent company Sandvik, this is the first time the Rammer name has been at the Hillhead show since 2007. But the company has not been idle. None of the representative models on display were more than two years old.

It’s exhibit featured the company’s Large Range of hydraulic hammers: the 3,540 kg Rammer 4099; a pair of 2,350 kg Rammer 3288 models, one in heavy duty, the other in hard rock configurations; and a 1,700 kg Rammer 2577. Designed around a new operating principle that can be matched to specific applications, the Rammer 3288 and Rammer 4099 are suitable for carriers between the 27- to 40-ton and 35- to 60-ton operating weight class, respectively, and benefit from a number of class-leading features. The new operating principle that combines stroke length, blow energy and Rammer's proven idle blow protector, is easily modified to allow breakers to be matched to individual carriers and applications, improving hydraulic efficiency and productivity. Both hammers deliver massive impact energy and a high blow frequency for exceptional power-to-weight ratio, the company said.

Viby Attachment Service
Viby Attachment has invested not only in dedicated UK sales representation for the first time, but also in setting up partnerships with other organisations in the UK to demonstrate – and deliver – its commitment to after-sales support. For example, it has set up a next-day parts delivery service partnership with Spillard Safety Systems, from its depot in the West Midlands, as well as a partnership network of expert engineers in the UK to ensure any urgent repairs and maintenance. The thinking behind these recent changes has now come to fruition, with UK sales hitting record highs in 2012, and with Viby’s profile and reputation now at least as strong as it was 25 years ago.

Weir Minerals Belt Tensioner
Gemex belt-tensioning systems – used in many process industries worldwide – are now available from Weir Minerals across Europe. The addition follows Weir Minerals’ acquisition of Sweden-based Gema Industri AB, the developer of the Gemex system at the beginning of 2012.

The hydraulically adjustable and mechanically lockable motor platforms allow belts to be checked and changed rapidly by removing the need to re-align the motor each time. Belt drives are one of the most commonly used transmission systems across almost every industry sector, driving fans, pumps, strainers, crushers, pulpers, compressors and other machinery.

Monty Riemann, Gemex product manager at Weir Minerals, said: “Belt-drive systems underpin a vast number of industrial processes across a wide range of sectors, because it has a number of innate advantages over alternative transmission methods, being quiet and highly efficient and delivering a large load capacity for its size. The Gemex belt-tensioning system removes one of the only down-sides to belt-drive systems – the time consuming process of changing worn out belts – by ensuring that alignment is only done once on installation. The drive transmission is a critical cog in any process and downtime can be very costly, so the potential savings this system can deliver are significant.”
