Using extensive customer feedback, 小松 re-engineered the D475A-8 - currently the world's largest production dozer. In this edition of Experts Corner, 乍得Perreault, Mining Dozer Technical Specialist at 韦德娱乐1946, shares his insights on how 韦德娱乐1946 and Canadian customers have helped shape the D475A-8的发展.

为什么矿山需要大型推土机?

关于采矿地点, 支持的机器, 就像推土机, can directly impact productivity by keeping blasting, 装卸区清洁, enabling loading and hauling equipment to work more efficiently.

So when the investment to have a dozer product as part of a fleet, it has to have a large enough capacity to match the payload of the other machines. We've been seeing significant growth in these larger dozers in the Canadian market.

What's special about the D475A-8?

的 D475A-8 is currently the largest production dozer in the world, bringing significant improvements over the previous model. One improvement is the dozer has 11% more power in reverse, opening the door to a broader range of practical advantages—the additional horsepower in reverse aids in faster ground speeds, yielding shorter return cycle times enabling the dozer to be up to 10% more productive than previous model. 的 total cost of ownership is also reduced over approximately 60,000 hours due to the durability improvements to the work equipment, 主机, 跟踪帧, 均衡器酒吧, 和枢轴.

所以总的来说, the dozer will remain in the field longer, and when it is undergoing maintenance, it will be back in the field sooner.

的 D475A-8's push group has been enhanced by changing the blade's link structure to a single-link design, 减少70%的叶片摆动. Other highlights of the design change are fewer greasing points, 可调节的关节, 还有更硬的结构. 也, 耳轴增大了16%, 具有更长的使用寿命, and can be reused by rotating 180 degrees, further decreasing maintenance costs.

顾客在说什么??

We're getting early feedback that the D475A-8 操作起来很舒服吗. It uses fingertip control which has been a big hit with operators. 的 finger tip controller(FCCS) improves operator ergonomics and operator stability when working on slopes or rough ground. We're actively monitoring the machine's performance to ensure that it meets our customer's needs, and we expect to have performance data over the next few months.

I should also mention that our customers love working alongside 小松 because the team is always actively listening and open to change designs and product improvements. We give a lot of care and attention to that conversation to ensure that the machine performs to meet the customer's application best.

So, customer feedback on previous models shaped many of the features of the D475A-8.

How does 韦德娱乐1946 add value to these conversations?

We work very closely with 小松 on two levels. 第一个, we have significant engineering and fabrication capabilities for adding modifications according to 小松 specifications. Our modifications or additions always get full approval from 小松 engineers and will not affect the warranty.

的re is quite a range of modifications depending on the type of mine and the customer's production objectives. 我们安装了一个最近售出的 D475A-8 58分.9 cubic yard super dozer blade, , which is 33% larger than the stock blade. Other changes included a ground-level isolator, 额外的照明, 不同的抓斗把手, 附加润滑点, 驾驶室里还有无线电. We install these modifications to give the product a finished look, so they don't look like add-ons.

Our work with product development and enhancements leads to the second level of involvement, where some of our recommendations get adopted by 小松 for future models. 的 new fingertip control is an excellent example– we developed that with our customers, 现在它是一个常规功能. This is possible because 小松 assigns engineers to work with us in Acheson, 也, 当然, 小松 is willing to accept feedback about their designs.

底线是:

像小松那样的大型推土机 D475A-8 is a significant investment for a mine, but because it is not part of the regular production chain, its performance requirements aren't as well established as those for trucks and excavators.

韦德娱乐1946 is working closely with customers and 小松 to close that gap to ensure that key requirements are identified and incorporated in modifications and future iterations of the product.
