NEW EQUIPMENT news
EvoQuip has launched a new addition to its impact crushing range : the versatile , fuel-efficient Cobra 230 impact crusher , suitable for construction and demolition , asphalt recycling , quarrying , and contract crushing . According to Matt Dickson , EvoQuip product line director , the quick set-up times , simple intuitive operation , and ease of transport make this machine an ideal solution for all applications . The user-friendly hydraulic assist , which comes standard , allows the operator to adjust crusher settings easily without tools . Powered by a fuel-efficient , high-performing direct-drive system , the Cobra 230 ’ s compact footprint makes it ideal for working in urban areas . Groundlevel access to the engine , hydraulics , service , and refuelling points , along with hinged radiator pack and hinged diesel tank , ensure easy maintenance .
The Martin Tracker Reversing , a new powered conveyor belt tracker from Martin
Engineering , delivers immediate and continuous precision adjustment of hard-totrack reversing conveyors , helping to reduce spillage and extending the life of belts and other system components . The unit , which can run on 110V / 220V power or a plant ’ s existing compressed air , can effectively centre the belt regardless of travel direction , and has greater durability and longer service life than previous designs . The Roll Generator has been designed to serve as a self-contained mini power station , with the tracker using an electric actuator to move the rolls and correct the belt ’ s position . The Martin Tracker Reversing is available in Lower Units for installation on the return side of the belt and Upper Units for use on the conveyor ’ s carrying side .
Bosch Rexroth introduces new hydraulic filter elements
Drive and control specialist Bosch Rexroth has introduced its new PURE POWER range of hydraulic filter elements , incorporating new materials that enhance filtration performance for hydraulic systems while reducing operating costs through increased service life .
Available in sub-Saharan Africa through Hytec Fluid Technology , the new range has been designed using new micro-glass material that , due to the very small diameter of the fibres , increases interstitial spaces in the same given area to trap and retain 50 % more contaminant particles than the range it is replacing . This means overall reduced cost of filter elements , their disposal and associated labour , as well as equipment downtime . “ Hydraulic fluid contamination remains the primary cause of system failures , with over 80 % of all hydraulic system failures due to contaminated fluid , so the need to optimise filtration performance is vital ,” explains Sandor Bottyan , general manager at Hytec Fluid Technologies ( HFT ). “ The new PURE POWER filter elements draw on state-of-the-art materials technology and Bosch Rexroth ’ s extensive industry experience to deliver long service life and optimum performance in a broad spectrum of industry applications .”
The ß-values of the new PURE POWER filter material have exceeded 1 000 in real world tests — significantly higher than the ß-value exceeding
200 requirements of ISO 16889:2008 — maximising system availability as hydraulic fluids are cleaned . It also prevents damage to the system and further contamination by removing a high proportion of the contaminants in the first pass through the filter .
The manufacturer has fitted all elements in its range with an additional antistatic conductive woven filter medium as standard , creating a charge exchange between oil and filter material and so , reducing the risk of electrostatic charge and discharge in the filter .
Filtration efficiency is even more effective when used with Rexroth filter housings with patented Cycloclean cyclone technology , where a doubling in dirt-holding capacity has been measured according to the ISO 16889 multi-pass test , while retention capability using the same test increases tenfold . This is a direct result of the cyclone design maximising filter capacity by effectively pre-filtering the fluid .
PURE POWER filter elements provide up to 50 % more dirt-holding capacity than older Bosch Rexroth filters , and are built standard with a conductive layer .
