Walker CAT

First Demonstration of SITECH GPS System on Caterpillar Excavator

March 6, 2012

First Sitech 2BELLE - Caterpillar and Walker Machinery Co. have partnered with Trimble’s SITECH dealerships to provide site - wide construction technology for jobsite needs, both in the office and in the field.
Improvements, such as antennas that use GPS satellite signals to compute its exact locations give contractors an easy-to-use, wide area measurement system for a variety of site preparation and stakeout applications. Cat machines are enhanced with technological features that assist in achieving every contractor’s goal of quality work, on time and on budget. Cat calls it “The Connected Worksite”.
On March 6, 2012 Walker and SITECH met with Kanawha Stone Co. to demonstrate the attributes of the SITECH GPS system on a Caterpillar excavator. According to Machine Salesman Steve McGrew, Kanawha Stone’s equipment managers already have several bulldozers that have been equipped with GPS equipment. But installing the equipment on an excavator is an entirely different story, he said. It concerns the difference in intricacies between the two machines.
First SitechOn a dozer, the GPS is installed on the blade and the only concern, to the operator, is the latitude of that blade as he/she travels along the road. First SitechGaining that correct lip soil height is the goal, which is monitored by the GPS. An excavator is more sophisticated, in that it can spin 360 degrees while the tracks remain in place. In addition, it has other moving parts: a boom, a stick and a bucket, which are moving all at once.
“The GPS started on the dozers and has become quite accepted,” McGrew said. “Kanawha Stone had never tried an excavator with GPS before. It is a little later in its evolution than a dozer.”
Field Technician Ronnie Williams, of SITECH demonstrated how new technology can be embedded into the machine and be fully functional. According to Williams, this excavator was the first to be equipped with GPS and demonstrated in Walker territory.
First Sitech1“They are seeing how this will make their lives easier and more productive, which is the whole premise of technology,” Williams said.
The machine the technology is installed on makes a difference, McGrew said. When sensors are installed on a non-Cat brand, sensors must be fastened on sides of steel. One sensor indicates the bucket position, another measures the stick position and another indicates the boom position. On a Cat machine, the sensors are more integrated into the machine from the factory, he said.
“We demonstrated that technology to Kanawha Stone,” McGrew said. “When everything is working right, the operator has the job site planned on his computer. He can work on slope, on banks, the road or the drain. All of these elevations, longitudes and latitudes are in the files used by the on - board computer software. With those sensors and the GPS monitoring where the excavator is, all the time, including the locations of the bucket, boom and stick, the operator can perform all of these tasks without checking with the survey man, which saves time and money. The savings in increased production and speed is worth the added cost of the GPS technology.”
Arrangements can be made to set up demonstrations through Walker Machinery.

Walker Machinery on Cutting Edge of Technology

May 5, 2011

Demo Day 3 029
Brent Sayre, owner of Sayre Excavating, in Kenna, tries out the high-accuracy Global Positing System that Walker Machinery Co. has made available on their Caterpillar machines.


RAVENSWOOD – According to Brent Sayre, a lot of people misunderstand how dirt works, such as where to put it, where not to put it, compaction and the impact of weather conditions. Every job posts its own challenges, he said.
Brent and his father Dencil own Sayre Excavating, in Kenna, W.Va. They attended Walker Machinery’s Caterpillar Connected Worksite Demo Day, May 5. The event was co-hosted by Charles Parker, training director of Local 132 International Union of Operating Engineers., at their training site in Ravenswood, W.Va. and Sales Manager Eric Ramey, of Cecil I. Walker Machinery Co. of Belle, W.Va.
“Most of the jobs I do have no plans,” Brent said. “I do things from experience. I drive the truck myself, most of the time. The hard part is figuring out with the customer, what they want and getting it done the right way. With the GPS, it shows you what’s there. You can actually do a layout and show a customer and say; here is what we can do on your site.”
Brent is talking about the high-accuracy Global Positioning System (GPS) that Walker Machinery has made available on their Caterpillar machines.
Demo Day 3 041Caterpillar is the first to offer a fully-engineered and integrated system from the factory select models of Cat equipment: Developed, designed, tested, integrated, manufactured and supported by Cat.
Many Cat machines are Grade Control Ready as standard, which simplifies system installation and optimizes reliability. Caterpillar and Walker Machinery have partnered with Trimble’s SITECH dealerships to provide site - wide construction technology for jobsite needs, both in the office and in the field.
Improvements, such as antennas that use GPS satellite signals to compute its exact locations, give contractors an easy-to-use, wide area measurement system for a variety of site preparation and stakeout applications. Cat machines are enhanced with technological features that assist in achieving every contractor’s goal of quality work, on time, and on budget. Cat calls it “The Connected Worksite”.
The demonstration was actually a three-day event, May 3-5. The first day benefited the Walker sales team, day two - the operating engineers, and day three - the customers. According to Ramey, in the commercial construction industry, the building commercial excavating contractor is up against serious competition in the bidding process.
“Usually on a project there are cost concerns involved,” Ramey said. “The developer wants it done as cost-effective as possible, which means they want it done right the first time.”
Demo Day 3 024Technology Sales Specialist with SITECH J.D. Weis presented a very basic understanding of the GPS process and an introduction to the technology for the applications contractors are starting to see in their bids.
“That technology is actually written in the specifications to use some kind of machine controlled guidance technology,” Weis said.
In an effort to standardize the work and to kind of guarantee the work, machine control and machine guidance products are being required now for any contractor to be able to bid on that work, Ramey said.
“They want people who are technologically advanced. They want people who know the industry and can do the work for them and achieve the accuracies they want,” Ramey said.
Blaine Furey, owner of Poncove, Inc. in Glen Daniel, W.Va. also attended the event. He has been excavating his entire life in the gas and mining industries. This is the first time he has explored this technology, he said.
“I’m not ready to do it yet, but I can see it in the future,” Furey said. “I’d like to start from ground level, keep up with it and kind of drift into it slowly.”
Technology is becoming a bigger piece of the machine, Ramey said.
“It is changing the way earth moving is done,” he said. “We want to be on the cutting edge of technology. We want to be the market leader of technology in heavy equipment. With these products, our customers can increase their profitability and decrease their costs, making them more competitive in today’s construction market.”
