The compelling case for high-pressure geroler motors

High Torque Low Speed (HTLS) motors using gerotor and geroler technology have been in use since the 1950s but are generally considered for low and medium pressure applications.

Eaton has been expanding the envelope by developing geroler motors that operate reliably at higher pressures, up to 345bar (intermittent pressure drop). High-pressure motors are able to accomplish more in a smaller package compared to medium-pressure technology.

When it comes to enhancing performance of both mobile and stationary hydraulic systems, high-pressure technology can be used to reduce package size, improve starting torque, and reduce system costs. At the end of the day, this means that skid steer loaders, drilling equipment, grinders and mixers, material handling and other mobile equipment can get more done, generate less emissions and use less fuel.

Switching from medium to high-pressure models is typically driven by three factors:

1. Equipment size: as machines become more compact and nimble, higher pressure products allow the same capability in a smaller envelope.
2. Capability gains: applications where more capable motors yield more productive or efficient machinery
3. Future compatibility: supporting future upgrades and changes

The Future Of Pneumatics As Aircraft Go More Electric

Pneumatic systems power and provide air for an array of aircraft functions. Best known are cabin pressurization and air conditioning, main engine start and anti-icing, but other functions include fuel tank pressurization, fuel tank inerting, avionics cooling and engine pneumatics.

Distinct from hydraulic systems, which tend to power mechanical devices such as flaps and landing gear, pneumatics also differ in that they use their medium—air—as a power source and a function. This has been the case for most of the modern jet era, but new technology is shaking things up.

Until the Boeing 787, most aircraft performed the pneumatic functions outlined above by drawing air from an aircraft’s ram-air intakes and from the engines using bleed-air systems. This can be inefficient, because a bleed system takes air that could be used for thrust. Furthermore, the ducting and valves needed to pipe that air around the aircraft add weight, and more bleed air is taken than can be used.

With the 787, Boeing replaced the traditional bleed-air control with electric-motor-driven compressors that feed the rest of the aircraft’s environmental control system (ECS), and changed its wing deicers from pneumatic to electric. In comparison with an Airbus A320, which can generate up to 270 kW of electrical power, the 787’s alternators can generate up to 1,500 kW—enough to power the homes of a small town.

One size doesn’t fit all

Those of us who work in areas with inclement winter weather know how important proper winter storm response can be. While only a part of our overall road maintenance responsibilities, our effectiveness when dealing with snow and ice events is the certainly the most scrutinized. Nine months of great road maintenance work and public goodwill can be completely wiped out in one mismanaged winter storm. Some agencies steadily outperform others during winter weather response. How do they do it, and what do they know that we don’t? More importantly, how do we get there?

Those are the questions the Johnson County Highway Department was asking during the winter season of 2013-2014. Salt supplies were depleted around our region, and we were fighting more frequent and colder winter storm events than usual. Staff were exhausted from top to bottom as snow event cleanup continued into subsequent winter storms. But public expectation of clear roads did not change, whether on our narrow low-volume roads or our suburban collectors pushing 15,000 vehicles per day. Located just south of Indianapolis, Johnson County is the fifth-fastest growing county in Indiana, due largely to suburban growth in the central Indiana region. Additionally, neighborhood streets account for roughly 22% of the total road miles in our unincorporated jurisdiction, which is rare for a county in our state. Goods still had to be moved, residents still had to get to work, and children still had to get to school. To say we had to get creative during that season to clear the roughly 1,200 lane miles in our jurisdiction would be an understatement.

However, we were watching other agencies finish their storm cleanup consistently faster than we were. We had seen this before in previous seasons but had accepted that we were facing different challenges than our municipal neighbors, such as fewer resources available per mile and blowing snow in rural areas, that required additional time. While this was all true, it was time to stop using this as an excuse for poor performance and develop a new way to deal with winter storms.

The first step toward improvement required learning as much as possible about available technologies and best practices for winter storm response. Through divine intervention, sheer luck, or something in between, we received a mailing for the 2014 APWA North American Snow Conference in Cincinnati during our difficult 2013-2014 winter season and decided to attend. This is where we were first learned the extent of what we didn’t know. While it was clear that improving our winter storm response would be a long-term and ongoing process, gaining access to training resources and making connections with vendors and other government agencies at this conference played a key role in developing a plan unique to our needs.

Market Forecast points to demand for energy-efficient hydraulic equipment

According to recent analysis from consulting firm Frost & Sullivan, the demand for energy-efficient hydraulic equipment is larger than ever, stemming from what they believe are “abundant opportunities in the areas of product development, system design, and cross-industry collaborations.”

Pulling from the Global Mobile Hydraulic Equipment Market Forecast, companies that adopt the position of hydraulic system providers in lieu of component suppliers will open themselves up to providing system-level solutions and strategic partnerships with IIoT service providers in order to broaden their product and service portfolios. Furthermore, greater customer emphasis on single-vendor solutions throughout the lifecycle is expected to drive capital investment in hydraulic solutions.

“Integration of hydraulics and electronics and the greater penetration of predictive analytics are expected to help slow down the market’s movement toward all-electric systems,” said Varun Raman, Industrial Automation & Process Control Research Analyst at Frost & Sullivan. “Electro-hydraulic equipment’s ability to increase energy efficiency, enhance control, and eliminate fluid leaks will restrict the growth of electric systems in applications traditionally catered to by hydraulic solutions,” he said.

Other noteworthy conclusions from the forecast are the inclusion of compact mobile hydraulic equipment and the role metal additive manufacturing might play in what they consider “customized mass manufacturing through a first-mover advantage by reducing product lead times.”

Frost & Sullivan’s analysis highlights growth, restraints, product segments, and end-user industries in the regions of North America, Europe, Middle East, and Africa (EMEA) and Asia-Pacific (APAC). The study also includes future growth opportunities, strategic imperatives for those opportunities, and CEO’s 360 degree perspective.

“The mobile hydraulic equipment market is receiving another major boost from the recovery of the oil & gas industry. This is especially evident in North America, which has a large installed base of legacy infrastructure, and in Asia-Pacific, which is investing heavily in new equipment,” noted Raman.

The Global Mobile Hydraulic Equipment Market Forecast is a part of Frost & Sullivan’s global Mechanical Power Transmission Growth Partnership Service program.

New process to extend serviceability of hydraulic aircraft components

The Air Force Research Laboratory Materials and Manufacturing Directorate recently completed an extensive effort to help certify a maintenance process that could extend the life of aircraft hydraulic system components.

Through participation in a rapid innovation fund team led by the Air Force Life Cycle Management Center, AFRL researchers successfully helped develop, test and validate the cold spray coating process for the life extension of aircraft hydraulic lines. Cold spray is a technique by which metal particles are accelerated onto a surface through high-pressure application. The force of the impact bonds the metal to the surface without the need for temperatures as high as those typically associated with other deposition processes.

This process was identified as a potential solution for replacement B-1 aircraft hydraulic lines, which are prone to chafing damage.

B-1 hydraulic lines are made of titanium, a strong, lightweight metal that can be bent and routed around tight spaces without collapsing upon itself. These qualities make it ideal for aircraft hydraulic systems. However, titanium does have drawbacks. It is a surface-sensitive material, meaning that any nick or scratch can be detrimental to its overall material properties. Because of the proximity of the B-1 hydraulic lines to landing gear components, chafing is a common occurrence, necessitating frequent inspection and replacement of hydraulic lines. This procedure is a costly and time-consuming endeavor.

To alleviate this problem, the rapid innovation fund team began investigating the use of the cold spray process to apply a protective titanium layer to chafe-prone tubing areas. The thought behind this effort was that the sacrificial titanium layer could endure considerable wear while preventing harm to the material beneath.

Certifying the process for implementation on the aircraft hydraulic tubes was a complex and multi-faceted effort on the part of AFRL researchers and project partners.

Loader cranes: Articulating technology

Typifying the current boom in the loader crane market is Dutch manufacturer Hyva which extended its range of hydraulic loader cranes with three new models at the end of 2017. The new models are the HC951, HC1151 and HC1651, rated at 95, 115 and 165 tonne-metres, respectively. Typical applications are in the rental service sector for multi-purpose loading activities with specialist driver-operators, explained Davide Catellani, Hyva director, cranes. “They also meet the requirements for heavy equipment and materials lifting in the oil and gas, mining, logistics, defence and construction sectors,” Catellani continued.

All three new cranes have continuous slewing with two slewing motors, the Liftrod Articulating System (LAS) for constant capacity through the radius range and the Extra Extension Speed (EES) and Smart Extension Sequence functions for faster operating speed, shorter load cycle times, and more precise and safer operation, Hyva said.

Another feature of the design is an integral base that allows the crane to be mounted directly to the truck chassis, reducing height and lowering the centre of gravity. As an example, the HC1151 with eight hydraulic extensions has a reach of 19.52 metres. Included is an automatic lubrication system to simplify maintenance and help maximise resale value.

In Sweden, buoyed by the success of its ePTO electric plug-in-system and Moffett E-series electric truck-mounted forklifts, on-road load handling equipment provider Hiab has continued focusing on maximising the eco-efficiency of its loader cranes. At the end of 2017 it launched the cyclone oil tank which, it claims, reduces oil usage, weight, space and running costs. “The patented technology introduces a new generation of efficient hydraulic oil tanks,” says Joakim Andersson, Hiab senior vice president, loader cranes. “The tank uses a cyclone system to remove air from the hydraulic oil returning to the tank, which is up to ten times more efficient than standard systems. The technology allows oil to be circulated and filtered more often, so that the size of the tank can be reduced. So, for example, instead of the 250 or 300 litre oil tank you would expect to find on a standard truck mounted with a loader crane, we can now fit a 100 litre cyclone tank. This reduced size and weight allows the truck to reduce its fuel consumption and lower its carbon dioxide emissions by up to 600 kg a year. The tank size and weight reduction also gives additional cargo capacity, plus the advantages of lower oil usage of up to 60 per cent, and a more durable hydraulic system, so operating costs are reduced too.”

A boost to swing torque: Cat unveils two new forestry machines 

Caterpillar has announced the launch of two new Cat forestry machine models — the 548 and the 548 LL — with increased horsepower, swing torque, lift capacity and tractive effort.

The new Cat forest machines are versatile, purpose-built track machines that can be customized to perform a complete range of tasks for forestry operations and contractors.

The Cat 548 forestry excavator is configured for forestry tasks ranging from road building and site preparation to processing logs roadside or at a landing. The Cat 548 LL is configured as a log loader and can perform log handling tasks, such as shovel logging, loading, power clam/butt-n-top applications and millyard activities.

The machines are equipped with an enhanced hydraulic system to deliver more power. Upsized pumps, the layout of components, and back-to-back main control valve all optimize hydraulic oil flow.

The hydraulic updates enable the 548 and 548 LL engine to run at a lower steady state rpm while maximizing power. Operating at a lower rpm saves fuel and lowers operating costs.

At the same time, the Tier 4 Final engine and features like a variable pitch fan, variable power modes, automatic engine speed control, one-touch idle and boom and stick regeneration valves also assist with fuel conservation. With automatic engine speed control, the machines will revert automatically to a lower idle speed when there is a lull in operation. Regeneration valves minimize oil required from the pump to maximize efficiency.

The 548 and 548 LL are powered by a Cat 204 hp C7.1 ACERT engine with increased horsepower that maintains maximum performance under load.

Strong hydraulic horsepower allows the 548 and 548 LL to handle a variety of work tools.

An almost 20 per cent boost in swing torque, depending on the model, provides more power to move trees, increasing production and efficiency. Heavy lift mode and other updates enable greater lift capacity to handle larger payloads with improved control, and tractive effort has improved by as much as 13 per cent to allow efficient manoeuvring when working away from the road.
