Enerpac History: Connections to WWII  

Enerpac History: Connections to WWII  

Editor’s note: It’s interesting to look at today’s tools and equipment and reflect onthe roles it pllayed in history. Enerpac’s history takes us back to the days of WWII. We hope you enjoy this history lesson.

 With a rich history of company transition and growth, Enerpac has deep roots dating back well before the WWII era. Known then as Hydraulic Tool Company, Enerpac supplied devices and products that were used during and after the war. These remnants of the WWII era continue to be found across Europe to this day.

 Lugentz Florent of Belgium found a Simplex Model 29 Mechanical Jack, manufactured in Chicago, IL, in the middle of a Belgian forest in fall of 2016. The forest is close to where WWII battles took place, which means the jack had been sitting in the woods unnoticed for over 60 years.

Simplex RJ2029 15 Ton 18” Stroke Ratchet Jack

It turns out this jack is the “great-grandfather” to Enerpac’s Simplex Model RJ2029 Ratchet Jack. It has an 18-inch stroke, 20-ton support capacity, and 15-ton lifting capacity. The product number 29 transformed into RJ2029 over the years as the product line expanded. The Simplex Model 29 was used in Western Europe during WWII and after, for bridge repair, lifting and positioning operations.

Simplex developed this “no hydraulics” system at the turn of the 20thcentury, manufacturing these jacks for over 100 years. The product is still used today for work on railway track systems. In 2007, Simplex was acquired by Enerpac and continues to be a world leader in mechanical jack systems.

Not only have Enerpac’s products transformed throughout the years, but they have also been designed and created for specific solutions that were needed after the war.

In the years following WWII, Germany rebuilt their infrastructure and transportation systems. While doing road maintenance and building new bridges, embedded, unexploded ordnance left from the war were found. These munitions need to be defused before being removed from their locations to prevent personal injury and property damage. Enerpac was approached to create a special tool to diffuse the bombs by carefully removing the fuse device. This operation required precise control of the process and a high level of applied force to accomplish removal.

The Enerpac cylinder tool met both of these essential requirements.

The diffusion tool consisted of a small, high-pressure hydraulic cylinder mounted into a frame assembly that would attach to the nose of the bomb and remove the fuse. To create this device, Enerpac used a model in testing the design and safety of the tool. This model has remained in the Enerpac lab and is always a topic of conversation for visiting employees.

While this project occurred in the late 1980s, it is believed this tool is still in use today.

In addition to hidden munitions, an abundance of equipment and tools were abandoned across Europe after the war. Some have been recovered and preserved, and are now displayed in museums.

 The National War and Resistance Museum, located in Overloon in the Netherlands, is the largest WWII museum in Europe. There are over 200 pieces of military vehicles and equipment displayed. One of the largest tank battles of WWII Battle of Overloon took place here between September and October of 1944. The battle lasted nearly three weeks and resulted in the deaths of many soldiers. The Germans defended their occupation of this area by attacking the Allied Forces, but finally retreated and abandoned their equipment at the site. The city of Overloon built a museum around the discarded equipment and left most in battle condition to keep the memory of WWII alive.

In the room that displays the tank support vehicles used to perform field repairs, a Porta Power hydraulic tool can be found. This tool from Applied Power, the parent company of Enerpac, was used for maintenance operations requiring the application of high force, such as bending, straightening and pressing. These tools are still produced and used today, performing very similar operations.

Enerpac’s reputation as being a technology leader began back in 1910 and still remains as the company continues to develop innovative tools for thousands of applications across virtually every industry. Enerpac products made their way into the war and part of history and will continue to deliver impactful solutions for the future.

 

Utah Landfill Shuffles, Gains Space

GPS rover and level/slope measuring system help relocate garbage to gain 2.3 million yards of landfill space

By Jeff Winke

Ask the average person on the street where garbage goes after the garbage truck picks it up and takes it away, and most will likely say, “the dump.” At one time, most communities had a town dump located near the edge of town or just outside. That was where town-folk could toss out anything.

One can imagine Andy and Opie hauling an old chair that Aunt Bee wanted out of the house to the Mayberry town dump. Fortunately, in 1976, eight years after the last episode of The Andy Griffith Show aired, the United States government passed the Resource Conservation and Recovery Act. This law put new rules into effect to protect water supplies and control how trash was thrown away. As a result, many dumps were closed or changed to follow the new rules.

There never was an episode showing toxic waste absentmindedly tossed into the Mayberry dump seeping into the ground and causing problems to underground water, streams, rivers, and the local “fishin’ hole.”

Today dumps are illegal, and trash is taken to a landfill. Modern-day landfills are sophisticated operations and are designed to receive garbage and keep the environment safe. A landfill has a liner system at the bottom to catch toxic waste that could pollute groundwater Trash is piled and smashed down to “fill” the landfill space.

Well before the federal law was passed, three forward-thinking cities near Salt Lake City, Utah came together in 1959 and decided to convert a popular dumping spot into a landfill. Slowly other local cities bought

into the project. Currently, the Trans-Jordan Cities Landfill is now owned and governed by seven cities with several other non-owning cities also bringing their Municipal Solid Waste (MSW) to the site. The once Mayberry-style community dump is now a technologically advanced, sophisticated landfill serving approximately 500,000 residents, as well as accommodating the commercial waste from the same south half of Salt Lake Valley region.

The Class 1, Subtitle D landfill is managed by Trans-Jordan, South Jordan, Utah. At the site, Trans-Jordan digs down a hundred feet from ground level and fills it up to a point higher than original ground level.

“Our company started with seven full-time employees and has grown to a staff of 39, plus five temps,” stated Jason Turville, operations supervisor at Trans-Jordan Cities Landfill.  “We take in 365,000 tons of MSW a year at the Trans-Jordan Cities Landfill with steady growth as the communities continue to build out and the demand increases.”

Since its start, the company has made conscious, concerted efforts to be a positive corporate neighbor. They offer an active Green Waste program where they accept, grind and mulch trees, brush and associated organic materials, which are converted into compost and chips that is sold to the public at a reasonable price. The compost is a high-quality product that meets the USCC (US Composting Council) certification for compost.

There is also a public convenience center (PCC) for residents to drop their trash on a hard, concrete surface with recycling of many materials including metal, carpet pad, Freon containing appliances, electronics, and second-hand store donations. Another service offered is a Household Hazardous Waste (HHW) collection and processing facility–free to residents and fee-based for small businesses.

The Trans-Jordan Cities Landfill currently accepts 365,000 tons a year of MSW from the 7 member cities which are West Jordan, Sandy, Draper, Riverton, South Jordan City, Murray and Midvale, as well as local commercial contributions.

“The best way to describe our company is ‘we manage airspace,'” Turville said. “Our job is put as much MSW into as little airspace as possible to maximize the life of the landfill space we have available.”

That goal of maximizing space was behind a recent Trans-Jordan project. The landfill has six cells. The company determined that they could gain significant space by relocating 500,000 cubic yards of MSW from a corner of an old cell to the new active cell. The move would literally gain 2.3 million yards of future landfilling space.

“Our current lowest elevation for our operation in Cell 6a has us at an elevation 50 feet lower than the bottom of the old trash placed in the corner,” Turville said. ‘Therefore, by moving it into the active area of the landfill, we gain the 50 feet of depth directly underneath and also from where the natural earthen slope will be removed to maximize the depth and space of the area.”

For the Old Cell 6 Trash Relocation Project, Trans-Jordan used a Cat 349F excavator and two Cat 740B haul trucks. Digging a new cell with an excavator is common practice, but digging trash out of an existing cell is not. The trash had been sitting there for 20-plus years and was very compacted. Trans-Jordan claimed that it actually was harder to pull out than dirt.

Trans-Jordan does not employ GPS machine control on any of its machines; however, they do use a handheld Trimble TSC3 GPS controller for establishing design grades and top of waste (TOW) grades. The Trimble rover is used for site measurement, stakeout, and grade checking operations. The controller, which is paired up with a Trimble R10 LT Receiver uses Utah’s VRS wireless network. In conjunction, all machines use JohnnyBall 3D onboard measuring systems, which is designed to provide operators with real-time level and slope.

“We manually put out stakes to follow, then use JohnnyBall as a tool to accurately maintain a level working area and establish a 4:1 working face on a daily basis,” Turville said. “Our MSW side slopes are 3:1 and with us having many new operators it is a great tool to teach them and show them the exact slope required for the operation.”

Base cups for JohnnyBall have been mounted in seven Trans-Jordan machines–dozers, compactors, an excavator, and a motorgrader–which enables the four JohnnyBalls they currently own to be moved seamlessly from machine to machine as needed.

“The GPS rover gives us the ability to take the site design created in our office and implement it in the field,” Turville said. “JohnnyBall helps our operators to efficiently and accurately build slopes where staking is not reasonable or appropriate–and it keeps the machine operator accountable to me and the other managers. The GPS rover used with JohnnyBall is a powerful combination that has become essential to our success.”

The Old Cell 6 Trash Relocation Project was completed in two phases. The company cut half of the old MSW and relocated it from August 2014 through Sept 2015. Phase 2–the other half–started up in May 2017 and finished October 2018.

The project occurred while continuing to take in 365,000 tons a year of MSW from the seven member cities and commercial traffic. The MSW that was moved was added into the daily processing amount.

For processing the trash daily, Trans-Jordan employs two Cat 836K landfill compactors equipped with JohnnyBall 3D onboard measuring systems to maintain a level top, 3:1 side slope, and a 4:1 working face. The company operates a Cat D5 dozer equipped with a JohnnyBall for dressing-up side slopes and working on finish slopes for liner placement.

“JohnnyBall has become a necessary tool to ensure we maintain 3:1, 2.5:1, and 2:1 slopes in the various locations,” stated Turville. “It is simple, easy to use, and provides real time feedback to the operator, which means a lot to us especially since two-thirds of the crew are green and learning how to achieve the grades we need, while working on their own.”

With the Old Cell 6 Trash Relocation Project completed, Turville reflected: “For years we will be talking and reminiscing about moving ‘old Cell 6,’ how this project helped extend the life of the landfill, and how interesting it was to ‘mine’ old trash and see what did and did not decompose over the 20 years it was sitting. A worthwhile and interesting project, for sure.”

Caterpillar Introduces New and Updated Products and Technology

NEW CAT® D6 DEBUTS WORLD’S FIRST HIGH DRIVE ELECTRIC DRIVE DOZER

TOP GRADING PERFORMANCE, FUEL EFFICIENCY GAINS

The all-new Cat® D6 dozer delivers new levels of efficiency and performance with a choice of Electric Drive or Fully Automatic power train. A redesigned purpose-built VPAT dozer offers best-in-class grading, while updated technology features help operators to be more productive from first pass to finish grade. Customer profitability is enhanced with up to 35% better fuel efficiency and reduced service and maintenance costs. An all-new cab resets the standard in comfort, while a range of configuration choices helps customers optimize machine performance for business needs.  At 215 hp (161 kW) and an operating weight range of 47,949 – 53,126 lbs (21 749 – 24 097 kg), the new D6 replaces the versatile D6T bulldozer.

Advanced Power Train Choice

This next-generation dozer offers a choice of advanced powertrain: the D6 XE with Electric Drive or the D6 with a fully automatic 4-speed powershift transmission.

The D6 XE is the world’s first high drive Electric Drive dozer, offering up to 35% better fuel efficiency and increased agility compared to the previous 3-speed model D6T. Constant power to the ground, continuous push, and greater maneuverability mean faster cycle times, making Electric Drive a top choice to achieve the highest level of productivity and fuel efficiency. Added D6 XE productivity and reduced fuel cost mean customers looking for these benefits can expect to see a payback of the added investment over a D6 in less than two years.1

The D6 XE features a next-generation Electric Drive system that offers high performance along with added durability. Simplified diagnostics and the serviceability advantages of a high drive dozer help reduce service and maintenance costs.

The D6 is powered by a 4-speed fully automatic transmission that provides increased productivity and up to 20% better fuel efficiency versus its 3-speed predecessor. The fully automatic D6 reduces momentary hesitation when the traditional machine shifts, so more momentum, and drawbar power are maintained through the entire push. Caterpillar engineers designed the auto shift to work up and down the entire working range, so power to the ground and fuel consumption are optimized for a greater percentage of the time. An added gear between first and second ensures more seamless shifting.

Both powertrains offer unprecedented ease of operation. The operator simply sets the ground speed and the dozer continuously optimizes for maximum power and efficiency based on load. With Electric Drive, there are no gears to shift. The fully automatic 4-speed powertrain optimizes the transmission without the operator having to worry about shifting.

Better, Faster Grading

Finish jobs faster by grading at higher speeds with a new purpose-built Variable Power Angle Tilt (VPAT) dozer. The newly designed structure is stronger, yet lighter, so machine balance is optimized for grading without the need for a rear implement or counterweight. A wide-gauge LGP VPAT design, with 36” centered shoes, puts more track on the ground to achieve 5 psi (0.73 kPa) ground pressure. Wider VPAT blade and class-leading range of motion improve performance, especially in trenching and backfilling applications. A new optional finish grading undercarriage has 10 bottom rollers for smoother grades at higher speeds, even in difficult surfaces like sand and gravel.

Technology Choices for Your Business

Increase overall job site productivity by up to 50 percent with a choice of Cat Connect GRADE technologies. Technologies range from standard Slope Indicate to full factory-integrated GPS, all supported by Caterpillar and Cat dealers.

  • Technology offerings on the D6/D6 XE are led by an updated, factory integrated Cat GRADE with 3D system. The new 10-inch touch screen offers a more intuitive operator interface that works like a smartphone, making it easy for operators to pick up quickly. The system uses advanced Inertial Measuring Units (IMU), which provide greater speed and accuracy without position sensing cylinders. Smaller antennas are integrated into the cab roof for even better protection. AutoCarry™ is included with Grade with 3D to automate blade lift to maintain desired blade load, improving load consistency and reducing track slip.

Additional GRADE technology choices include:

  • Cat Slope Indicate is standard, showing the machine cross-slope and fore/aft orientation on the primary monitor for quick and easy reference.
  • Cat GRADE with Slope Assist™ provides basic blade positioning assistance without the need for added hardware or a GPS signal.
  • Factory Attachment Ready Option (ARO) provides optimal mounting locations, brackets, and hardware and simplifies installation of an aftermarket grade control system. The new D6/D6 XE makes it easier to install any brand of grade control system, with specific mounting locations for grade control components. The position of the main display and grade control display can be swapped so operators can choose their preferred location.

Cat LINK telematics technology helps take the complexity out of managing job sites – by gathering data generated by equipment, materials, and people – and serving it up in customizable formats.

  • Product Link™ collects data automatically and accurately from equipment assets – any type and any brand – which can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink®. Cat dealers can help configure a customized subscription, available with cellular or satellite reporting or both.

Greater Durability, Reduced Service and Maintenance Costs

The new D6/D6 XE is designed specifically to reduce service and maintenance costs by up to 12 percent, with updated components, longer service intervals, and fewer scheduled maintenance tasks. Easy access to grouped service points and regular maintenance items, plus a new ladder at the back of the machine, help reduce time spent on routine maintenance and inspection.

Undercarriage updates are designed to save money and maximize service life. A new Heavy Duty Extended Life undercarriage features Positive Pin Retention pins and link improvements for up to 20% more seal life in high impact conditions. Common structures for Heavy Duty and SystemOne™ undercarriage enable changes from one to the other.

A new Cat C9.3B diesel engine has a redesigned fuel system that provides greater durability and more accurate fuel delivery. Elimination of the NOx Reduction System and a simplified single engine Electronic Control Module (ECM) help increase reliability.

New Standard in Cab Comfort

A completely redesigned cab raises the standard in comfort and productivity. A brand new 10-inch touchscreen display provides an easy-to-use operator interface. The standard air suspension seat is wider with added backward adjustment, plus the entire armrest adjusts independently of the seat for customized comfort. Heated/cooled leather seat options are available, and all offer a variety of seat adjustments to customize cushion length, headrest position, lumbar support and seat tilt. More storage spaces have been added throughout the cab.

The new dozers are easy to operate too – with Electric Drive or the Fully Automatic powertrain, operators just need to set the ground speed and go. The machine optimizes performance and efficiency with no added shifting required. Agile turning, especially on the D6 XE, means faster cycle times and more able to work in smaller spaces.

Distributed cab heating/cooling, with automatic temperature and blower control, circulates air more effectively around the operator. Less air directed toward windows helps reduce fogging/frosting. Integrated ROPS and 15% more overall glass area help increase visibility.

Equipped for the Job

The D6/D6 XE is available in VPAT or push-arm configurations with standard or two widths of Low Ground Pressure (LGP) undercarriage. A variety of blade types, track shoe widths and rear attachments enable the machine to be optimized for primary types of work to be done. Waste Handling and Forestry arrangements also are available, equipped from the factory with specialized guarding, seals and other features to help ensure long life in harsh applications.
