New equipment launched at Bauma construction equipment exhibition

Deeper, faster, quieter and with greater efficiency and improved accuracy sums up what the latest equipment for the geotechnics industry will offer when it is launched in Germany this spring. These new innovations will be among many new developments for the construction industry that will be on display at the tri-annual Bauma exhibition in Munich from 15 to 21 April this year.

Bauma is not only the largest construction equipment exhibition but, at 555,000m2, it is also the largest exhibition of any type in the world. This preview is a taste of what will be on offer for the ground engineering market at Bauma but many companies wait until the show opens to reveal details of new equipment, so a visit is well worth it if you are looking to position your business at the forefront of technology.

Bored piles

Bauer will be launching the Value Line and Premium Line versions of its BG drilling rig range, as well as a new tablet PC system for rig operators to monitor their work, check the condition of their machine and send drilling logs and maintenance issues to the office or workshop.

The company said that the new versions of its BG rigs have been developed as a result of customer demand for more basic rigs that are optimised for Kelly bar drilling for use in less developed markets. The Premium Line rigs will be capable of carrying out any rotary drilling technique.

Liebherr will also present the latest addition to it rotary drilling rig range with the launch of the LB 44, which extends the range upwards and offers the capacity to drill to 92m depth and up to 3m diameter.

Trevi’s equipment manufacturer Soilmec will show its new generation of SR hydraulic drilling rigs for large diameter piles, which have been redesigned to improve productivity and operating flexibility. The new rigs also feature a new cab that is said to improve operator comfort.

Delmag has announced that it will be launching the RH24 and RH28 rigs, which replace the existing RH22 model. Both models will feature a new docking system to improve the ease and speed at which the rotary head can be changed.

Driven piles

Bauer’s subsidiary RTG Rammtechnik will launch an updated version of the RT 21 T pile driver, which will be displayed on the BS 65 RS base carrier that has now been fitted with a new system to cut noise by up to 6dB(A). RTG will also display its newly developed RM 20 rig for hydraulic hammer applications which features a telescoping tilting mast.

PTC has said that its new 20RHFV vibrodriver is equipped with variable moment technology to help minimise noise and vibration levels during pile driving. The driver can also be fitted with a number of different clamps to allow it to be used with casings, as well as sheet, timber and concrete piles.

ABI has announced the launch of the Mobilram-System TM17 telescopic mast for piling rigs, which will be presented with the new MRZV 28VV vibrator. The company has said that both developments have focused on improving fuel efficiency and the new mast is easier to set up as it doesn’t require a crane.

ThyssenKrupp will be showing innovations in sheet pile design with the launch of ThyssenKrupp Bautechnik’s TKL sheet piling range. Its ThyssenKrupp Tiefbautechnik business will also launch new developments for pile driving.

ThyssenKrupp Tiefbautechnik will have a number of new solutions for the offshore pile driving market on display, as well as a new pile vibrator with a sound dampening system and its new Eco-Power system to reduce fuel consumption. The company has also said that a new excavator-mounted vibrator with side grip will be unveiled for the first time at Bauma and is aimed at sites where height is an issue.

Ground anchors

ABI subsidiary Interoc will unveil its AN150 anchor drill rig at Bauma. The new rig is equipped with a height-adjustable control console and a rod changer magazine, and can be fitted with remote control.

Soilmec will present the new SM-8, SM-14 and SM-16 drilling rigs for micropiling and anchoring, which have been developed with Puntel. The main focus has been on improving safety and the rigs now feature remote controls.

ThyssenKrupp Bautechnik will present its new TK-ASF drilled injection pile solution, which can be used as a back anchor or as a foundation pile. Anchors of up to 32m in length are possible using the solution and use of easy-to-process steel grades also allows for high load reserves between yield strength and tensile strength of up to 30%.

Diaphragm walls

Soilmec will be demonstrating its research and development investment with the display of a concept hydromill that the company believes is capable of creating diaphragm walls to 250m depth, well beyond the 100m depth that has been possible until now. The 250t Tiger SC-200 system has been successfully tested on a trial site near the company’s factory in Italy. The company will also present a version that is capable of drilling to 150m.

According to Soilmec, the main challenges of developing the new hydromills was coping with the pressure needed to pump bentonite fluid to such depths, as well as managing the verticality of the excavation. Mining work, dam improvement and tunnelling schemes are seen as the main targets for these machines.

Sennebogen’s stand will feature the new 55t 655 HD duty cycle crawler crane, which is designed for foundation construction as well as dragline operations. The company has said that it will also present a new diaphragm walling grab.

Bauer will also launch the BC 35 trench cutter, which is based on the BC 12 but extends the cutter frame to 12m. The new model is said to improve precise steering, even on soft soil, through wider spacing between the larger steering flaps.

Diaphragm walling applications will be the first to benefit from Liebherr’s new hybrid technology with the launch of the new HS 8300 HD duty cycle crawler crane. Liebherr has said that the hybrid design has been proven in maritime applications and helps to improve fuel efficiency.

Rock drilling and tools

Safety and efficiency has also been a focus for the development of new machines for the rock drilling segment.

Initial field trials of Atlas Copco’s new Flexiroc T45 drilling rig suggest that fuel consumption has been halved compared with the previous ROC F9 model. The new rig also features fewer hoses and couplings so maintenance of the rig is improved. Functionality has been improved with adjustable air flow and dust collection and a folding boom for easier transport.

The new Alpha 330 drilling tools from Sandvik have been designed to increase rod life, improve collaring accuracy and drill straighter holes. The company says that the tools have been developed to match the increased energy output from high power rock drills now used in drilling and tunnelling applications. The new design replaces the R32 connections with a shorter thread design that Sandvik says results in a more rigid, integrated drill string to resist ending stresses and transfer more energy to the drill bit.

Sandvik’s new DC125R wheeled top hammer drill rig replaces the DC122R model but features improved manoeuvrability on difficult ground conditions. The remote controlled mini drill rig is designed for drilling 22 to 45mm diameter holes for a wide variety of applications, including foundations, rock bolting and drill and blast.

Wassara will be presenting its water powered drilling solutions which it believes is more suited to sensitive environmental applications than conventional compressed air drilling. Wassara will show a number of case studies of projects in applications such as geothermal, jet grouting and maritime drilling that could not have been achieved using conventional techniques.

Directional drilling specialist Vermeer has announced that Bauma will be the debut of the company’s move into the rock drilling market with the launch of the D36x50DR rig, which will be exhibited alongside the new D60x90 directional drill rig that is designed for the soft ground directional drilling market.

Breaking and rock scaling

Sandvik’s hydraulic breaker specialist Rammer will launch several new breakers at Bauma. The three additions to the small range are the Rammer 255, 355 and 455, which fill a gap in the Rammer lineup, and are suitable for carriers in the 1.2 to 5.2t operating weight class. The heavier end of the Rammer product line-up will also be extended with the introduction of the 5011 hammer, which is design for carriers in the 43 to 80t operating weight category.

Furukawa Rock Drills will not be launching any new rigs until next year’s ConExpo in Las Vegas, but will be showing its new greasing system and seals to protect breakers in scaling operations at Bauma.

Tunnelling

Aker Wirth’s development of a mobile tunnel boring machine (TBM) for the mining sector is one of the tunnelling innovations that is nominated for a Bauma innovation award. The system was developed for Rio Tinto but the system, which combines the flexibility of a road header with the robustness of TBM, could be used in civil engineering.

The self-propelled machine moves on a crawler and a walking mechanism and excavates rock with six powerful hydraulically actuated arms fitted with disc cutters. The muck is conveyed to the rear of the machine by a loading apron with loading disks and via a chain conveyor where it is loaded.

In addition to Herrenknect’s TBM solutions, the company will also present its new Pipe Express semi trenchless pipe layer, which has also been nominated for Bauma innovation award. The system reduces the space needed for pipe laying activities by up to 70%, reducing land rental issues.

US-based Tei Rock Drills will unveil its new DrillAll 50 mini jumbo at the exhibition. The company has said that the drill is ideal for difficult to access sites and smaller projects involving blast hole drilling, rock bolting, soil nailing or micropiling. According to Tei, the drill features higher torque than other models to deliver greater efficiency on site.

Atlas Copco will launch its new Boomer E-series at Bauma. The redesigned tunnelling rigs feature touch screen control and new operating software that allows for 3D reporting of construction progress.

Moba has announced that it is to launch a new version of its MD S-2000 blast hole drilling system, which uses GNSS antennae to record the drill mast orientation to ensure holes are drilled accurately and according to the site plan. The system also records the drilling angle, depth, time, GPS position and motor data of the drilling device.

Monitoring

Topcon was one of a number of companies to announce collaborative developments with Autodesk at the end of last year. Bauma will be used as an opportunity to highlight how this collaboration on BIM software will benefit customers in a range of applications, including surveying and monitoring.

Materials testing

Italian laboratory equipment manufacturer Controls will be presenting new concrete testing equipment - the Automax range - as well as its latest development for asphalt testing with Pave Lab. The company will not be showing any innovations for the geotechnical market but will have market specialists on its stand.
