BAUMA PREVIEW
gear units made from sustainable biomass .
GearFluid Poly 220 E1 is the first CO 2-reduced gear unit lubricant on the market made from sustainable biomass , with CO 2 emissions at the end of the lifecycle of GearFluid Poly being 84 % lower than conventional polyglycol oils , according to SEW-EURODRIVE . Consequently , this new premium lubricant helps customers reduce their overall corporate carbon footprint .
While offering maximum wear protection for the gearing and the rolling bearings , the premium lubricant ’ s low friction coefficients increase gear unit efficiency and , compared with conventional biodegradable oils , GearFluid extends the interval between lubricant changes by up to 300 %.
Pump servicing workshop
Tsurumi , a dewatering pump leader , intends to lift the veil on its new safety pumps at Bauma 2022 , offering visitors the chance to learn how to service a pump properly .
For the first time , the exhibitor is coming to the show with a workbench where visitors can demonstrate their skills . The task is to service a pump , especially in the sensitive areas of hydraulics and electrics , reinforcing the need to carry out regular maintenance to avoid pump failures .
Safety is also the focus of the new product presentation , which the Japan-based company has saved as a further treat .
The company will debut the KRDX , a model in its new series of safety pumps that are approved according to IECEx and ATEX standards .
The three-phase submersible heavy-duty pumps are designed for slurry drainage / pumping and have motor outputs from 3.7 kW to 7.5 kW . They are equipped with an agitator and an outlet of up to 100 mm to pass solids up to 33 mm in size . Tsurumi states a pumping capacity of 2,200 litres / min .
Completing the safety trifecta will be Tsurumi ’ s Connect system for monitoring of pumps and other machines , including those from third parties . Via a small box on the unit , the operator can determine the location , read out performance data and set alarm and error scenarios . The aim is to raise safety and efficiency to a new level , with the first systems already in use on the market .
The manufacturer will also use the show to provide information on many other pump models , including the LSC2.75S residue dewatering pump , and the KTZ and KRS pump series .
Mine development options
To this point , Austria-based Wimmer has set its

Wimmer ’ s Blue Badger progressing through rock at a gemstone mine owned by Suacuai Mineracao LTDA in Brazil
sights on the tunnelling industry , with its flagship Blue Badger tunnel boring machine ( TBM ) being used around for tunnel cross-sections from 3.5 m in height .
Since the release of the original Blue Badger in 2018 , the company has supplied around 20 machines to projects across the globe . One of these was for a gemstone mine owned by Suacuai Mineracao LTDA in Brazil where the machine was previously boring through rock that had a uniaxial compressive strength of 60-120 MPa .
The company has expanded this range with the miniBadger – for driving tunnels with a crosssectional area of 6.2 sq . m or more where the working height is 2.7 m – and the eBadger – a TBM driven by an electric motor that delivers up to 50 kW of power on battery for tramming and positioning and is connected to the mains infrastructure while tunnelling .
The introduction of the Yellow Fox is where the company could potentially find further mining applications .
Based off a Liebherr 914 Compact Litronic superstructure with a Liebherr 920 Compact Litronic undercarriage , the Yellow Fox can be used for working heights of 4.2-7 m . As with the Badger family , the excavator boom is custommade by Wimmer , offering high breakout and tear force alongside a boom that can be swivelled by 45 °. All heads can also be switched out , changing from , say , a roadheader attachment to a drill , depending on the application .
The Yellow Fox is powered by a 90 kW US Tier 4 Final-compliant engine .
