“The more common business model is to rent the basic attachments that will not only provide a decent return on investment, and often higher than standard fleet, but it also will encourage the rental of core pieces. If you do not offer an attachment that is generally expected to be in your fleet, your competitor will. Any opportunity you allow your client to go somewhere else is an opportunity you also provide for your competitor to develop the account and service their next requirement,” Durante says.
Ron Schwieters, product manager, Komatsu, says the company’s approach is unique in that it uses externally mounted cylinder sensors on the boom, stick and bucket. These are position sensors; there are IMUs in place in other locations on the machine. Compared to other designs using internal sensors, he says, Komatsu’s approach yields faster sensor response times and components that are easier to maintain. Schwieters says their system stores the entire bucket profile, not just the teeth. The semi-automatic system is active only when the bucket or other attachment is in contact with the design surface. Even when the semi-automatic is running, the operator runs the excavator as usual. The performance of the system enables the intelligent excavator to complete tasks that, in the past, would have required a dozer and excavator working together. Because the intelligent excavator can do much of what a dozer has done in the past, that dozer can now work in other areas of the project or on another project.
The operators said that the R 920 also was adept and powerful when handling the bucket in a front-shovel configuration.

“The dedicated style is like the Wain-Roy, the wedge style or the Volvo S3 style coupler where the coupler will only mate to a bucket with a special top connection,” says Lee Horton, Leading Edge Attachments. “The advantage of this method is that the tip radius is usually very small, the weight is relatively low and the buckets can be used with several of the same size class machines fitted with the mating coupler. With this style coupler, because a bucket can be used with many different OEM excavators, it is great for rental houses or larger contractors with multiple machines because they don’t have to worry about matching the bucket to the machine in the same size class.
And it is not just the O-rings in the company’s seal nuts that make them versatile, ZaGO’s seal nuts are also highly corrosion resistant. While typical plastic insert lock nuts are only offered in steel, which is prone to oxidation (rust), the company offers its self-sealing nuts in stainless steel, which has superior hardness. Stainless steel is also easily cleaned and sanitised. Strength and corrosion resistance often make it the material of choice in aerospace, transportation, food, medical and processing equipment industries. ZaGO seal nuts are also offered in other materials including brass and aluminium.
