PRODUCT LAUNCH // CAT 6040 “AT THE HEART OF THE 6040 IS A PAIR OF 32-LITRE CAT V12 ENGINES, WHICH OFFER A COMBINED GROSS POWER OF 2079HP”
The new Cat 6040 is available as a 22-cubic-metre face shovel or backhoe, designed to load up to 4000 tonnes per hour.
LATEST 400-TONNER David Wylie reports on Caterpillar’s new 400-tonne class hydraulic mining excavator, the mighty 6040 decade after buying the RH range of mining-class hydraulic excavators from Bucyrus, Caterpillar has closed the historic former O&K factory in Germany. These monster miners are now designed in Tucson, Arizona and built at Cat’s Batam factory
A
in Indonesia. In addition to promoting the latest versions of its 300- and 600-tonners at the recent Minexpo show in Las Vegas, Cat took the opportunity to launch the new 400-tonne 6040 model. The 6040 is designed to load up to 4000 tonnes an hour with a 22-cubic-metre capacity bucket, either as a backhoe or in the classic O&K configuration of a TriPower face shovel. It can load a Cat 785 in four passes, while it’s a five-pass match to a Cat 789 and a six-pass match to Cat 793 mining trucks. Both types of front-end working equipment have a design life of at least 60,000 hours. At the heart of the 6040 is a pair of 32-litre Cat V12 engines, which offer a combined gross power of 2079hp (1550kW). Interestingly, this massive twin power pack meets the Stage 5 ultra-low emissions
standards without the use of either a diesel particulate filter or an AdBlue system. As has already appeared on the 600-tonne 6060 model, the 6040 receives Cat’s new heavy-duty undercarriage. It features extremely durable rollers and idlers that have duo cone seals, steel-back bronze bearings for increased service life and to eliminate overheating during tracking. Updated track pads and a track tensioning system are also part of the new undercarriage package, which is intended to lower long-term operating costs. NOVEMBER 2021
