3) Adoption of one-touch start function
A one-touch start switch is installed to start and stop the equipped work equipment (feeder, crusher, conveyor, side con-veyor and magnetic separator) by touching one button switch, to free the operator from complicated operations .
3 Environment
Engine meeting Tier3 exhaust gas regulation The Komatsu SAA6D125E-5 engine that accomplishes low NOx and PM emissions thanks to the electronically controlled common rail injection system and cooled EGR system is equipped
2) Control of dust
A sprinkler nozzle is installed above the crusher as a standard specification to control dust that is generated in the crushing of rocks and stones during crusher operation. As options, sprinkler nozzles are prepared under the crusher and at the conveyer tip
As an option, a sprinkler tank and pump can be installed for convenience in locations where tap water cannot be supplied at all times
3)Transportability
The following structure has been adopted taking transport-ability in an assembled condition into consideration.
(1)3-direction hopper folding and unfolding structure
(2)Folder side conveyor
(3)Opening and closing of guard above crusher
(4)Folder conveyer (Can be folded at sea freight)
4. Conclusion
The mobile crusher has been developed incorporating the sales points mentioned above to upgrade the product power and to enhance its durability by tackling higher reliability as a major theme.
In the initial stage of and during the development work especially, the entire structure was re-examined with a focus on structures and machine cover by reviewing FEM analysis conditions and test conditions through load measurement at user operating sites, through the analysis of and counter-measures against market claims and through the addition of conditions.
The mobile crusher has been prototyped and put into high volume production through the energetic cooperation of the related pisions and departments.
The product has been placed on the market recently. Assured product enhancement will be pursued in the future also by promptly following up market information and re-quests.
5.A few word by writer
Since the introduction of Komatsu’s first-generation Galapagos model to the market in 1992, the in-house recycling technique has become a routine practice at demolition and civil engineering work sites in Japan. On many occasions, Komatsu’s Galapagos crush-ers have been sighted at work sites.
Since then, the machines have continued to advance while the environment surrounding us has experienced many changes. Recalling the days before and immediately after starting the development work, it is indeed memorable that a crusher with a new, unique mechanism could be developed and manufactured in house.
The BR580JG is a large mobile crusher of the 50-ton class, for which the market demand is highest in the overseas market. It is hoped that more of the BR580JG will be sold and will serve the users well.
