Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Together We Serve - Parker Fluid Systems DivisionCorporate social responsibility (CSR) means different things to different people. For some, it means improving the communities in which they live or helping feed people in need of assistance. Other people prefer to support the military and military families. At Parker Aerospace, CSR efforts include all these causes and more thanks to a variety of support efforts provided by Parker employees.

Together We Serve is the collective name given to the many initiatives that make up CSR at Parker Aerospace’s Fluid Systems Division (FSD). Parker Hannifin provides corporate support through the Parker Foundation with grant money for charitable organizations. The selected organizations are nominated by local employees, and through a review process, the site chooses the specific charities that become recipients of the grants. In addition, the local Together We Serve team identifies the charitable initiatives and determines which organizations we will offer employees opportunities to support through either volunteering their time, donating items, or giving money to purchase the necessary items for donation.

In the case of FSD in Irvine, California, the local charities selected for the first half of 2019 included projects that help feed people, care for animals, and support families.

Second Harvest

Parker Employees Volunteer to Support Local Social Causes - Second Harvest - Parker Fluid Systems DivisionSecond Harvest is a large foodbank near Irvine, California, that serves children, senior citizens, and even entire families in need. It is open to anyone whose income falls into what’s considered below the poverty level, which includes some military families. Last year, the non-profit food agency served approximately 250,000 people in the Irvine area. The food bank depends on volunteers to sustain approximately 40 percent of its manpower.

Twenty-three Parker team members and their families (including some children) worked at the food bank during a Saturday in February of 2019.

“People on the Second Harvest team had a sense of purpose and desire to give back to their communities ... Events like Second Harvest help employees feel more engaged with Parker and help them pass compassionate values on to their children.”
— Jennifer Perez, human resources specialist at Parker FSD in Irvine, CA

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Second Harvest - Parker Fluid Systems DivisionPerez noted that team members came from many different roles at Parker. “We had people from engineering, quality, finance, and human resources,” she reports. She indicated that they all worked together with a different type of teamwork and energy compared to their regular workplace routines.

“It was exciting to work around the table with my husband and people I care about,” explains Perez. “It was a different experience, like a race. People were eager to sort one type of food, then ask what else we could get done for the food bank. We wanted to hit record numbers. Afterward, there were lots of high fives and we had a great lunch together.”

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Second Harvest - Parker Fluid Systems DivisionTo get the work done, team members gathered around a large table, broke open large bulk packages of food, eliminated any rotten or expired foods, and then re-packaged the food into smaller parcels for families. Parker employees also sorted donated towels, diapers, formula, and other items based on the needs of select groups like families with small children or senior citizens living by themselves.

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Second Harvest - Parker Fluid Systems Division“When working around the table, there is an energy that is contagious,” says Perez. “Time flies, but it’s also an eye-opening experience when you reflect on the people who benefit from the work.”

Orange County Animal Care

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Orange County Animal Care - Parker Fluid Systems DivisionIn addition to Second Harvest, Parker employees volunteered for an animal care project on a Saturday this past May. FSD members came together to help a local animal shelter in need of a good spring cleaning. With lots of enthusiasm and a can-do attitude, volunteers set to work to help the Orange County (OC) Animal Care organization.

This nonprofit operates 14 shelters and takes in more than 30,000 animals annually. During the event, the team was able to tour the Irvine facility, visit the animals, and pitch in with cleaning areas of the shelter devoted to abandoned and rescued animals.

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Orange County Animal Care - Parker Fluid Systems DivisionA total of 22 Parker team members visited the Irvine OC Animal Care facility. There were also a few children who volunteered with their parents. All volunteers were clearly animal lovers.

Some volunteers and staff ended up adopting animals, according to OC Animal Care’s Public Education Officer, Brittany Hayes. She indicates that quite often volunteers find animals with which they build special bonds.

“Volunteering at OC Animal Care is definitely a feel-good thing,” says Hayes. “It’s almost an indescribable feeling because you are contributing to the well-being of the animals at the shelter. Whether you’re walking a dog or helping clean a kennel, you are making that animal feel loved and giving them a better opportunity to get adopted.”

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Orange County Animal Care - Parker Fluid Systems DivisionOC Animal Care often hosts children volunteering with their parents. “Getting children involved in programs not only builds self-confidence, but it teaches them empathy,” notes Hayes. “Whether they are reading to an animal or if they are making them blankets, even the smallest hands make a big difference!”
Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees Orange County Animal Care - Parker Fluid Systems Division“I think all employees who volunteered for this day at OC Animal Care are genuine animal lovers,” says Janet Dunscomb, the event coordinator and a cost/price analyst specialist at FSD. “So, they were very happy to be presented with an opportunity for themselves and their family members that combined their love for animals, their desire to help the community, and a chance to meet and get together with other Parker employees on a non-workday.”  

Dunscomb received very positive feedback during the event and the day after. “I think everyone was very happy they participated and happy that Parker provided this opportunity,” she explains. “For those who want to continue volunteering in the animal world, this introduced them to new potential opportunities they could pursue after the event.”

South County Outreach

Parker Employees Volunteer to Support Local Social Causes - South County Outreach - Parker Fluid Systems DivisionA donation drive for local children attracted a great deal of heart-felt support from Parker FSD employees in 2019. Through a multi-faceted push that included email from Parker team leaders, visible drop-off bins strategically located within Parker facilities, and an internal website devoted to registrations, Parker was able to  organize 106 backpacks for South County Outreach, near Irvine, California.  

The organization has a vision to end hunger and house hope in Orange County, California. Providing an innovative food pantry and transitional housing program, South County Outreach helps homeless families get back on their feet with the tools and counseling they need to succeed. 

Additional charity through CSR

Parker employees in Irvine have also supported Easter baskets and multiple gift card giveaways for Thanksgiving dinners for military families. Other charities selected by FSD in the past have included Toys for Tots and Angel Tree.

Parker Employees Volunteer to Support Local Social Causes - Parker Aerospace employees outreach through CSR - Parker Fluid Systems DivisionIn Irvine, the Together We Serve team has eight members, which includes Perez, who helps bring volunteer ideas to other team members and then organize the events. The CSR team members sometimes serve as a specific event “champion.” Then, anywhere from 10 to 25 additional employees may volunteer for each event that CSR team members publicize. The group of volunteers changes with each activity.

“We are trying to offer a diverse grouping of opportunities to inspire new volunteers where they might feel drawn to participate,” explains Perez. Employees have previously supported a wide variety of charities through onsite donations of food, school supplies, gifts for the elderly, and toys for children at Christmas time.

“We did not have a formal program geared to serve in the community until recently,” says Perez. “In 2018, I had the opportunity to see how another company was supportive within the community through “serve” events. Ever since then, I have been working with a team here in Irvine to target those types of activities.”

The impact of giving

Parker Employees Volunteer to Support Local Social Causes - 5K Tustin Hangar Run - Parker Fluid Systems DivisionPerez also believes that CSR initiatives like Together We Serve helps Parker attract better employees because today many individuals are looking for more than just a job. They want a sense of purpose. CSR initiatives allow for a better balance of purpose in an employee’s work/life balance. “There is definitely a level of personal satisfaction,” says Perez.

“I know the employees on the team feel a deeper sense of purpose when they can be involved in the team and CSR events, especially if it is one to which they are naturally drawn.”

— Jennifer Perez, human resources specialist
at Parker FSD in Irvine, CA

Perez added that for her, and for most of those who volunteer, the smiles at the end of an event truly reflect joy in the opportunities to give back in some way. “It's two-sided,” she adds. “To the person receiving support, and to the person offering support, it fills the heart to give or receive.”

Power Shift Power Take-Off (PTO) Troubleshooting Dump Truck Chelsea Products DivisionParker Chelsea’s Power Take-Off (PTO) is designed and built to meet the demands of the mobile equipment industry. The Chelsea PTO is intended to provide a long service life, both on-highway and off-highway. In order to maximize the life of Chelsea’s PTOs, it is important to have the PTO in proper use and constantly maintain the PTO as well. 

The Chelsea PTO application worksheet and owner’s manual will help you properly specify your PTO and install it. However, the understanding of how a power shift PTO operates will help the troubleshooting process run more smoothly and effectively. For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. This locks the PTO output gear to the output shaft and allows work to be done. When the power shift PTO is disengaged, the solenoid de-energizes. Air or hydraulic fluid deadheads against the valve. From there, air is released to atmosphere through a valve, and hydraulic fluid exhausts into the PTO. 

Here are some breakdowns of the potential causes and solutions for troubleshooting the PTO. It is first important to understand that many problems from a Power Shift PTO are the result of incorrect plumbing. A good first procedural step can be found in the Owner’s Manual, which is to compare what pressure is coming from the air or hydraulic source against what pressure is entering the PTO. 

PTO unit not engaging

Dealing with the PTO unit not engaging, these are some of the potential causes with solutions for shifting problems from Power Shift PTOs. (Probable causes are listed in a logical test sequence. Don’t assume any one thing is wrong.)

Power Shift Power Take-Off (PTO) Troubleshooting Electronic Overspeed Control Operation Products Division

Chelsea has developed the next generation of Overspeed Controls for Power Shift PTOs. This system helps prevent the driver from going down the road with the PTO engaged and prevents the power take-off and driven equipment from being operated at excessive speeds. When the Electronic Overspeed Control Operation (EOC control) is changed to the “on” position, it energizes a solenoid valve that pressurizes the clutch pack. This then engages the PTO. A main feature of the EOC is the measuring of speed of the PTO electronically and uses that measurement in comparison to the selected overspeed RPM setting. If/when the PTO exceeds the preselected RPM setting, the EOC will de-energize the solenoid valve, disengaging the PTO. The PTO will remain disengaged until the speed has been reduced to the preselected reset speed. At that time, the PTO will re-engage. 
It is a very simple set up with easy set-up buttons. LED lighting is outputted in three settings for great visibility in the EOC. When the PTO is in overspeed protection mode, audio and visual blinking overspeed warning alerts the operator. This system can be used in applications including LP Gas Trucks, Water Trucks, Fire and Rescue, Aerial Devices, Dump Truck & Trailers, Snow and Ice Removal.

Managing EMI and Lightning Strike Protection in Today's Aircraft - Aircraft - Parker ChomericsComposite materials have been replacing metal structures throughout the aircraft industry primarily to save weight, improve fuel economy and reduce costs.  But the lack of electrical conductivity in these materials is a disadvantage when compared to the conventional metal airframes of the past. The conventional, metal airframe allowed designers to take advantage of the natural Faraday cage it formed to protect equipment against interference. There were many opportunities to ground items of equipment reliably by connecting directly to a convenient surface ground.

Today, a typical airframe consists of around 50% composites. Major structures include the fuselage and wing fairing, as well as large sections of the wings, fin and horizontal stabilizers. 

  Causes of electrical interference

Inside the aircraft there are numerous electrical systems capable of generating EMI which can potentially disturb the operation of critical systems. These include fluorescent lights, light switches, dimming circuits, AC-powered window heaters, motors and generators, data and power cables, and transmitters such as radio and radar. 

External storms are also a major source of potentially disruptive electrical interference and can cause physical damage to the aircraft through lightning strike impact.  

  Recovering lost properties

Replacing metal structures with composites means compromising the EMI shielding and lightning strike protection of the aircraft, as the composites themselves are not electrically conductive. To overcome this issue, woven or non-woven copper-aluminium mesh, or an expanded foil, can be embedded in composite structures to restore lost shielding and grounding properties. The embedded metal provides an optimal combination of electrical conductivity, weight, and corrosion resistance. Solid metal strips can be used in the radome area to handle very high concentrations of lightning energy. 

Embedded conductors, however, do not solve all the technical challenges that come with the increasing use of composites. It is very difficult to ensure reliable electrical continuity between individual composite panels after the airframe is assembled and still promote conduction of lightning energy. 

Electrical components are typically bonded or grounded directly to the airframe. These connections to the mesh can often fail to meet the very low impedance requirements because of environmental stresses such as vibration and temperature variation. The exposed mesh in the locations where grounded or bonded modules are made (fig 1, at left), can be vulnerable to environmental exposure (temperature, humidity, oxidation) that increases electrical impedance.

  Applied performance enhancement

To overcome this challenge, a lightweight coating such as Parker Chomerics CHO-SHIELD technology can be applied to optimize conductivity in this area. CHO-SHIELD® 4994 is a highly conductive, silver-filled polyurethane coating designed for aerospace applications and has superior EMI shielding properties. The coating provides excellent adhesion and wear resistance and is resilient to most operation and environmental fluids. The coating is compatible with many primers and top coat systems.

In areas where high corrosion protection is needed, a copper-based urethane coasting such as Parker Chomerics CHO-SHIELD® 2002 can be used. When used on a composite, CHO-SHIELD 2002 provides the conductivity necessary to achieve excellent shielding effectiveness while maintaining its electrical and mechanical stability in hostile environments. CHO-SHIELD 2002 is designed to be used with Chomerics CHO-SHIELD® 1091 primer to ensure correct adhesion. 


The aircraft antennas will also need to be shielded and grounded against lightning strike. This can be achieved by using an expanded woven MetalasticTM EXP-URE gasket material. Electrically conductive grease can be applied at ground connections, to support reliable electrical connectivity under temperature and vibration. Attention must be paid to viscosity and surface-wetting properties when formulating greases for aerospace applications. Parker Chomerics CHO-LUBE® 4220 has a resistivity better than 100mΩ-cm and is an example of an aerospace-grade grease. It is formulated to support electrical interconnections, improve metal to metal contact and provide long-term oxidation protection for exposed mesh or electrical terminals.

Conductive sealants such as Parker Chomerics CHO-BOND® 2165 or CHO-BOND® 1019 can be applied at locations requiring electrical continuity and environmental protection. Typical airframe areas treated are screw holes, fasteners, antenna connection points and exposed conductors on external areas. Where conductive gaskets are used to promote electrical continuity between composite components, a conductive sealant can be applied to provide improvement in continuity. These areas are generally around the wheel wells, engine mounts, wings and the tail section, where high vibration occurs (figure 2, above). 

In addition to these methods which will improve EMI performance throughout the airframe, a lightweight conductive heat shrinkable tube such as Parker Chomerics CHO-SHRINK® 1061 can be used to shield the aircraft’s cabling against the effects of EMI and can provide a weight saving of up to 60% compared to traditional methods.
