Why Municipalities Are Paying Attention to Kaiser Walking Excavators

Unmatched versatility and outstanding performance

The Kaiser S2 Walking Excavators are in a class of their own. Billed as the ideal all-around machine for a variety of deployments in the toughest terrain, these workhorses can truly handle any jobsite. Whether you work on steep slopes, in riverbeds, or even on impassable marshlands, the Kaiser S2 can get you where you need to go. Because of all of these extraordinary capabilities, the Kaiser S2 walking excavators have become the go-to solution for municipalities throughout the United States.

 

“We clean all of our storm ditches and ponds out with the Kaiser,” says Janice Storm, maintenance supervisor for the City of Oldsmar, Florida. “It literally walks on water, so we are able to go places that we could never go before. We have almost eliminated flooding in our town thanks to the machine. We also use it after storms for cleanup since the Kaiser can walk down a street blocked by debris to pick it up and clear the way for first responders.”

A variety of attachments for any application

In addition to its unsurpassed maneuverability and power, the Kaiser S2 can also handle a variety of attachments to make any municipal job easy. Whether you’re looking for grapple hooks, mowing heads, ditch cleaning buckets, or a demolition hammer, the S2 has the hydraulic capabilities to effectively power whatever tool you need.

 

 

In Putnam County, Florida, the Kaiser S2 is affectionately known throughout the municipalities as the “spider”. “Putnam County is about 850 square miles and most of it is rural,” says H.P. Tompkins, public works director. “There is a lot of off-road work that needs to be done, and the county did not have the type of equipment that was capable of doing what the Kaiser S2 does. The neighboring county where I came from had a spider, and we had to borrow it several times to do some emergency work until we were able to purchase our own.”

 

Now that Putnam County is equipped with the Kaiser S2, municipal crews have gone to work in areas previously inaccessible to conventional equipment. In addition to improving productivity, Tompkins believes it has also improved employee morale. “If you want us to do the job and to provide the service to the residents, we need the equipment to do it. It means a lot to the crew to have the right equipment.”

Oscillating v. Vibrating Rollers: Which is Right for Your Business?

When choosing a compaction machine, an important consideration is whether to purchase a vibratory or oscillating roller. Both systems have advantages and disadvantages, so it is important to understand the differences so you choose the right machine for your job.

Vibration
Traditional vibrating rollers are equipped with one or more weights rotating on one shaft in the center of the drum. When the mechanism rotates, the drum begins to vibrate, causing compaction forces in a downward direction to the soil. This is what typically increases the compacting force up to six times the actual static weight of the drum assembly itself, allowing for greater compaction with fewer passes. However, due to the up and down movement, the roller drum is not in contact with the ground for up to 50% of the time it is in motion.

Oscillation
An oscillating roller is equipped with two rotating weights placed away from the center of the drum, which generates an oscillatory motion. This means that, opposed to a vibratory roller, the drum does not move its axis of rotation, but rather oscillates around it. These changes in force provide compaction energy both horizontally and vertically to the front and rear of the drum. Unlike a vibratory roller, the oscillating roller does not lift off the ground and maintains constant contact with material.

Which is best?
Vibratory rollers have long been the workhorse of the compaction business, and have a history of providing excellent results. These machines are able to achieve uniform compaction with a wide variety of materials, and produce good depth effect.

Oscillating rollers have recently started to gain more widespread use due to their benefits. These rollers provide continuous ground contact to reduce the number of passes needed compared to vibratory machines. In addition, they offer a higher degree of compaction without destroying the granular structure of the asphalt. Simply put, you cannot over compact with an oscillating roller. Finally, they produce a perfectly smooth surface, and provide optimal, dynamic compaction all the way to the joint without harming the cold road surface.

If both systems offer benefits to your business, or if you can’t decide, Sakai manufacturers machines that have both options on one machine. The Sakai SW850ND is one example of a machine that offers the best of both worlds, and may be the perfect solution for your business.

Citrus County Road Maintenance Updates Their Vacall Fleet

Citrus County Road Maintenance Updates Their Vacall Fleet
When it was time for Citrus County Road Maintenance Department to purchase new equipment, they called GS Equipment, their dealer for over 15 years.

Long Lasting Equipment
The last time the department purchased a new Vacall machine was in 2003. “The machine held up really well,” said Larry Brock, Assistant Public Works Director at the Citrus County Road Maintenance Department. “Twelve years is a long life for a machine, especially one that works on municipal projects that require continuous use in harsh conditions. After talking with our salesman, we are now considering purchasing the AJV912 sewer jetting and vacuuming machine.”

Durable Design
Vacall uses a variety of materials that outlast other brands, including thicker steel for the debris tanks and aluminum baffled water tanks. For a company operating in Florida, though, the galvanized debris body is especially important. “We’re a coastal county which means we encounter a lot of salt water while we work,” explains Mr. Brock. “The galvanized debris body on the Vacall prevents rusting. None of the other manufacturers offer that.”

Recommended Dealer
The Citrus County Road Maintenance Department can’t afford downtime; they only have one sewer truck to service the entire territory. They trust GS Equipment to keep their Vacall up and running. “We’re very happy with the level of service and expertise at GS Equipment,” says Larry. “We recommend them anytime a company or another municipality is looking to make an equipment purchase.”

Storm water drainage with XL 3100 IV model is priority for spring rainfall preparation

GS Equipment Gradall Case Study 97aLike most cities and counties in the state of Florida, keeping storm water drainage mechanisms clear and functioning is a top priority for Casselberry, Florida. From catch basins to culverts and retention ponds, water management is a critical job for this city – a residential community on the outskirts of Orlando.

GRADALL VERSATILITY ADVANTAGES
Not long after the city of Casselberry took delivery of its XL 3100 IV Gradall excavator, it was put to work clearing soil and vegetation from critical drainage culverts along Rt. 436. “The material that has collected in front of the drains is anywhere from one to four feet deep, collecting over several years,” said Rod Wongus, crew supervisor for the storm water division of the city’s Public Works Department. “GS Equipment Gradall Case Study 97bWith the Gradall, we can clear away the entrance to about four catch basins a day, and then clean out the inside of the pipe with a hydro excavator. Without the power and boom movements of the Gradall, we’d have to do it by hand – a much slower and, obviously, labor intensive process.” With a short rear tail swing, the XL 3100 IV can be positioned and maneuvered along the edge of the six-lane highway, only blocking one lane. Operator Scott Mandigo said that not only is it easier to reposition the carrier from the upper cab, the machine is quieter, more powerful and more sensitive to movements of the joystick controls. “I really love this machine,” he said. “It’s also very good in swales.” That’s another storm water management task for the machine, according to Wongus. During the dry season – before the spring rains – the Gradall will be used to dredge about 23 miles of ditches and low-lying swale tracts to make sure water runoff can be handled efficiently. “When that is done, we’ve got plenty more for it to work on, like sidewalk replacement and general repairs,” he said.

XL 4100 IV meets county’s needs for mobile equipment that can handle different jobs

GS Equipment Gradall Case Study 96aBrevard County, Florida, is one of the largest counties in the state – known mostly as home of the John F. Kennedy Space Center on the east coast and serious about maintaining its infrastructure with high-value equipment. On a jobsite at Merritt Island in the county, the Public Works Department relied on just one piece of equipment to unearth and repair a water line beneath a street and then replace an outdated catch basin cover followed by loading dirt.

GRADALL VERSATILITY ADVANTAGES
“We use it daily,” said operator James Aquino of the county’s XL 4100 IV excavator. That day, the Gradall was used to remove pavement and then dig down five and a half feet to determine the cause of a leak that had created a dip in the asphalt pavement. At the end of the workday, the Gradall boom was used to install steel covers over the hole for overnight safety. GS Equipment Gradall Case Study 96bThe next day, Aquino used the XL 4100 IV to remove the steel covers, refill the hole with limerock and then spread more fine aggregate material, creating a smooth grade with the delicate Gradall bucket movements. After compaction, a crew topped off the hole with asphalt. But that wasn’t the end of the workday for the Gradall. From the upperstructure cab, Aquino drove the machine several hundred yards down the street onto a grassy park area, around a guardrail and fence and into position to repair a catch basin cover. Never once leaving the operator cab, Aquino removed an old concrete cover over a cGS Equipment Gradall Case Study 96catch basin and replaced it with a new one, precisely positioning the huge concrete slab with the XL 4100 IV precise boom movements. “This machine is used for all kinds of jobs, like pulling out old sidewalk, removing trees, highway repairs and ditch cleaning,” said Aquino. “And lots of times, at the end of the day, we use it to load trucks with fill dirt to be used at different locations the next day.” Aquino, who has been operating Gradalls for about 10 years, said he is very pleased with the Series IV model. “With the automatic transmission, it’s much easier to get down the road from the equipment yard to wherever we need to work,” he said. “It’s also a lot more comfortable and easier to work with because it has more power.” Changing the mobility controls from the carrier cab to the upperstructure cab is also much easier than with earlier models, he said. “I like this one a lot, and I can get a lot more done with it on an average day,” he added.

Site development project gains efficiency without the need to stop and lower outriggers

GS Equipment Gradall Case Study 95aHigh efficiency work practices are critical for American Engineering Development Corp. of Hialeah Gardens, Florida – a major site development resource for general contractors and developers in South Florida. With over 400 employees and state-of-the-art equipment, American Engineering strives to complete large and complex jobs in the most efficient way possible.

GRADALL VERSATILITY ADVANTAGES
An XL 3300 III Gradall excavator was a key piece of equipment assigned to complete a massive site work project around a modern eight-story apartment complex being constructed in Plantation, Florida. Moving dirt, rock and debris and then creating a complex landscape plan included the creation of a retention pond, intended to collect rain water on the property. GS Equipment Gradall Case Study 95bRobert Roscoe, who has operated Gradall excavators for about 10 years, was at the joystick controls of the XL 3300 III as he moved large pieces of material and carefully tilted the telescoping boom and 60-inch bucket to carve out the retention pond. Although the XL 3300 III was equipped with outriggers, Roscoe said he never uses them. “I don’t have to,” he said. In fact, wheeled Gradall excavators have front axle oscillation locks and a strong, low-profile boom and chassis that creates excellent weight distribution and allows the machine to move and place heavy loads at the front, rear or either side of the machine – all without the need for optional outriggers or to lower an optional grading blade. “Outriggers would slow me down,” said Roscoe. “If a machine requires me to use outriggers, I would have to stop, lower them to work, then raise them to move the carrier to dump in a truck and then repeat the process. That takes a lot of time.”

Replacing culverts in residential neighborhood is faster and more efficient with XL 4100 IV

GS Equipment Gradall Case Study 94aMaintaining infrastructure is an ongoing challenge for most municipalities and counties throughout the U.S. At Port St. Lucie, Florida, near the state’s east coast, the drainage division of the city’s public works department has an ongoing program to replace culverts in residential neighborhoods. Functional culverts are important for collecting and channeling storm water, but they can become ineffective if the pipes deteriorate or they become overgrown with vegetation.

GRADALL VERSATILITY ADVANTAGES
The city of Port St. Lucie uses an XL 4100 IV excavator for its culvert replacement project, which includes replacing steel pipes that were installed beneath concrete driveways up to 20 years ago. GS Equipment Gradall Case Study 94b“The process starts with cutting concrete on the driveways,” said Bob Colson, crew leader for the drainage division. The XL 4100 IV removes the pavement and then carefully excavates dirt from around the culvert pipe before actually removing the pipe. “If the pipe is in good condition, we set it aside and re-install it later,” said Colson. “But a lot of them have rusted away and have to be replaced with aluminum.” The XL 4100 IV is used to clear out dirt to restore the proper grade before re-installng pipe and then spreading dirt and aggregate in preparation for a new concrete driveway section. “With the Gradall, we can replace three driveway culverts in a day, and also lay new lines between the culvert pipes under the driveways,” said Colson. “Without the Gradall, we’d have to do it by hand and we couldn’t manage anything near that level of productivity in a day.” Arthur Agnew, who said he’s been operating Gradall excavators for nine or 10 years, said he really appreciates the automatic transmissions that are standard on Series IV models with highway speed undercarriages. He drives the XL 4100 IV from the equipment yard to work sites every day. “The new Series IV excavator is also a lot more powerful than the Series III models,” said Agnew, adding that he also appreciates how fast he can transfer mobility functions from the carrier cab to the upperstructure cab. Although there’s an in-cab switch to change the joystick configuration from Gradall to Deere or SAE, Agnew said he prefers the original manufacturer’s pattern. “That’s what I’ve always used, but I can see where it would come in handy with a new operator,” he said.

With powerful telescoping, tilting boom, Model XL 4200 handles important highway drainage work

GS Equipment Gradall Case Study 54aInterstate highway projects can be among the most multifaceted construction projects. Some aspects of the work are highly visible. But other project elements are less dramatic and less often seen, including cutting drainage ditches alongside new pavement. And yet, proper drainage swale excavation and construction can be of key importance to the overall success of the project.

GRADALL VERSATILITY ADVANTAGES
In Fort Myers, Florida, Kiewit Southern Co. used a Gradall® Model XL 4200 to create important channels at a new interchange along I-75. GS Equipment Gradall Case Study 54bOutfitted with a 60-inch ditching bucket and its standard telescoping, tilting boom, the Model XL 4200 was used to efficiently cut contoured swale slopes, excavating to create flat channel bottoms and then create sloped sides to meet the plan specifications. The ditches run for about three-quarters of a mile along the entrance and exit ramps on both sides of a new Alico Rd. interchange. Ditches must have a 5-foot-wide flat bottom and sloped sides with a depth of one foot to one-and-a-half feet, depending on location. “We tried cutting the ditches with a trackhoe with a bar welded across the bucket teeth,” said Jonathan Farrar, Kiewit Southern’s grading superintendent. “You can do it that way, but the Gradall was able to do it a lot faster.” GS Equipment Gradall Case Study 54c“It’s doing a good job,” added operator Don Blakley. Production ran several hundred yards per day, excavating material with the Model XL 4200 and then loading it into trucks where it was stockpiled for future use. After shaping the ditches, the Gradall excavator’s tilting boom was used to efficiently line the ditch with a 6-inch lift of topsoil, after which it was seeded and mulched.

At busy mining operation, Model XL 4200 II handles rugged cleanup work

GS Equipment Gradall Case Study 51aVulcan Materials Corp. operates a demanding aggregate mine in Brooksville, Fla., that requires constant spillage cleanup to keep the operation working efficiently. Once aggregate is mined, it must be moved and processed before it can be sold as finished rock and sand, mostly used in the manufacture of high quality cement and asphalt. GS Equipment Gradall Case Study 51bTransporting the mined material, including highly pourous limestone, in trucks and on conveyors creates a great deal of spillage that must be removed from under and around conveyors, crushers, scrubbers and hoppers. All are locations that are difficult for most machines to access and not practical to clean up by hand.

GRADALL VERSATILITY ADVANTAGES
Since early 2006, demanding spillage cleanup functions at the Vulcan Materials mining site have been tackled by the Gradall® Model XL 4200 II.The Gradall boom telescopes horizontally GS Equipment Gradall Case Study 51cbeneath the conveyors and other equipment. Often working in locations with little or no overhead working space, the task could not possibly be handled by a conventional knuckle boom. Front-end loaders and other smaller machines do not have the capacity or durability to handle the demanding aggregate cleanup. For even greater reach capability,Vulcan has a standard boom extension for extra horizontal reach under conveyors, plus the company has a live boom attachment that is able to reach over obstacles and into holes. This is also helpful when the Model XL 4200 II is used to clean limestone residue out of truck beds. “The power of this machine is very good,” said Terry Lee,Vulcan’s maintenance supervisor. “It fits everywhere, and it has excellent boom-end strength.”
