The design and deployment of aerial lifts, truck-mounted cranes, telehandlers, scissor lifts, man lifts and other modes of vehicular material handling demands two requirements above all others:
Safety for the operators
Operational integrity for the vehicles
Achieving these dual goals requires constant monitoring of out-of-level conditions. For three-quarters of a century following the Industrial Revolution, analog technologies addressed this challenge with visual indicators at each axis, which an operator then had to diligently monitor, making mechanical adjustments to ensure personal safety and the safety of the load—a task that required extreme vigilance and precise execution.
By the last decades of the 20th Century, electronic controllers powering audio signals and flashing lights had arrived on the scene to help reduce a handling system’s dependence on the operator’s monitoring of individual gauges for each axis of control. Many of today’s material handlers continue to rely on such electronically powered alert systems.
But with the advent of the Internet of Things (IoT) and the near-limitless interconnectivity possibilities it presents, a seismic shift has occurred in material handling control. The Universal Tilt Sensor (UTS) technology was specifically designed to optimize operator and load safety while facilitating interconnectivity.

OEM designers benefit from open protocol connectivity
Universal Tilt Sensors operate over a CAN bus using an industry-standard SAE J1939 communication protocol and an integral Deutsch DT four-pin connector. With UTS, OEM designers can deploy one product to achieve single, dual or three-axis mobile control, while it's plug-and-play connectivity with a full range of Parker hydraulics and electronic control components ensures system-compatible data collection, monitoring, and alerts. The communication scheme also facilitates daisy-chain-style single-harness configurations that reduce exposure to accidental cutting and pinching and other operators or environmentally induced damage.
For OEMs and their customers, this means one single part can perform the many functions that formerly required a multitude of individual products, slashing inventory requirements, simplifying both installation and replacement, as well as reducing related labor.
Compactness and versatility
UTS technology features a low-profile form and three slightly offset mounting holes around its diameter that make it easy to install and remove, even in challenging field conditions. This fool-proof mounting profile ensures the UTS is properly and consistently mounted across a vast array of machines while enabling a full range of horizontal, vertical and angular mounting positions.
Meets robust and reliability
UTS technology features glass-filled hybrid-plastic construction with no moving components and is designed to resist corrosion and vibration. Its robust sensor technology can withstand rugged material handling environments. With a spin weld design and a sealed connector, environmental protection for outdoor as well as indoor applications is ensured. The UTS is rated IP68/IP69k in all orientations, and IP68 upside-down. For lifts working around electric or magnetic fields, UTS provides effective insulation against electromagnetic and electrostatic interference, meeting or exceeding EMI and ESD ISO environmental protection standards. In addition, customers who have field tested the UTS reported it providing predictable linearity over its specified operating temperature range (-40°C to 85°C) and without deviations experienced with competitive products.
Where the IoT connectivity comes into play
Perhaps most exciting of all is the infinite possibilities for connectivity possible using UTS technology. This closed-loop electro-hydraulic solution communicates over an open, industry-standard protocol, enabling plug-and-play IoT connectivity to controllers, hydraulic components, data collection, and reporting software, as well as to the entire family of Parker hydraulic and electronic products and accessories.
Design engineers, OEMs, and operators new reality
Ladder engines using UTS for auto leveling and boom elevation transmitting operational behavior back to an OEM design team, which they can use to analyze safety-lapse trends and improve next-generation vehicles
Refuse trucks, dump trucks or forestry equipment operating on steep inclines transmitting individual route profiles back to the home office to identify problem areas and improve safety training
Material handlers transmitting information on operator behavior to spot and intervene when irresponsible handling repeatedly requires override intervention
Every mobile hydraulic vehicle’s field performance being monitored by OEMs to facilitate warranty reviews and reduce liability
Bringing this all together
As more and more components and processes attempt to leverage the IoT, UTS technology will become a drop-down configurable component within an increasingly complex, interconnected system that:
Promotes operator safety
Optimizes equipment performance
Provides comprehensive reporting for analysis and improvement
Increases productivity through predictable maintenance and improved uptime IoT connectivity
Improves customer satisfaction and loyalty through proactive data-driven service engagement
Selectively shares data across distribution and supply channels

Celebrating 50 years since humankind’s lunar landing and our significant role in that achievement
On July 16, 1969, Apollo 11 launched and on July 20 was the first landing of humans on the lunar surface with Parker Aerospace making the journey possible - from blast off to first step, and the return. Parker equipment provided vital functions on all three booster stages (first, second, third stage), the Command Service Module (CSM), the Lunar Module (LM), and even the astronauts’ suits.
From the development of the program, the early tests of Apollo 7 and Apollo 8, the landmark Apollo 11 landing, and through the final Apollo 17 Mission, Parker played an important role in the historic events. Parker Aerospace is proud of the important role played by our engineers and equipment.
During prelaunch operations and during the mission, Parker made sure the crew and spacecraft were safe. The ground support shutoff valves located in the launch pad complex directed liquid oxygen and fuel to the various Apollo systems. Eight six-inch ball valves were used during the fuel and oxygen fill operations of the first stage. The valves were also used to drain the vehicle in the event of an extended hold condition on the mission. Ten eight-inch pre-valves were used during the fuel and oxygen fill operations for the vehicle second stage
Fluid systems throughout the Apollo vehicle relied on specially designed Parker seals and fittings to prevent leaks that could cause serious mission delay. Critical sealing applications, such as the vehicle observation windows, relied on Parker seals to safeguard the astronauts. High-precision tube fittings, designed to meet exacting NASA specifications, were used throughout the vehicle to ensure leakproof, dependable connections on essential systems.
Beginning with ignition through the entire flight of the first stage, the four-inch ball valves circulated and maintained liquid oxygen (LOX) for the engines while the gaseous oxygen (GOX) flow control valve maintained a constant tank pressure during the first-stage operation.
After burnout and separation of the first stage, the accumulator reservoir manifold assembly (ARMA) provided the hydraulic energy for positioning the second-stage outer engines to assure proper mission trajectory. One hydrogen control valve and one oxygen control valve regulated the second-stage hydrogen and oxygen flow to the propellant tanks to maintain a constant propellant pressure during operation. Propellant shutoff valves were installed in each of the second-stage engine inlet lines. These valves would close in the event of an emergency, to shut off fuel to the malfunctioning engine.
When the vehicle reached an altitude of approximately 108 miles above the Earth, the second-stage separated, and the third-stage ignited. At the time of ignition, the LOX check valves served a vital function by preventing liquid oxygen and liquid hydrogen backflow into their respective supply tanks. Further protection of the all-important third stage was assured with the use of highly reliable hydraulic check valves throughout the hydraulic system.
During the entire mission, from countdown to separation of the service module prior to re-entry, the Apollo program utilized the Parker fuel cell reactant supply modules and oxygen and hydrogen modules. The fuel cell reactant supply modules controlled the flow of hydrogen and oxygen to the fuel cells, which furnished complete mission electrical power. The oxygen and hydrogen modules controlled the temperature and pressure in the oxygen and hydrogen storage tanks. Oxygen used for cabin pressurization was also controlled by this module.
The oxygen control assembly performed vital pressure control through the entire mission until lift-off from the lunar surface.
The assembly also controlled the oxygen used to pressurize the LM cabin and the astronauts’ suits. In addition, the oxygen control assembly was used to fill the astronauts’ backpacks for their lunar exploration. This assembly received high-pressure oxygen from the LM supply tanks and regulated the pressure to a usable level.
When the moment arrived for the astronauts to leave the lunar parking orbit and proceed to the surface of the moon, a command was given for Lunar Module (LM) separation from the Command Service Module (CSM). From here, the reaction control system (RCS) maneuvered using reaction control valves that were used to turn the LM to the descent attitude and control steering and attitude during descent to the surface of the moon. These valves were also critical to astronaut safety during ascent from the lunar surface and during hover, rendezvous, and docking maneuvers.
The descent engine was used to slow the LM from the lunar parking orbit and guide it to the lunar surface. The engine propellant tanks were pressurized by a Parker pressurization system. This system was comprised of a helium pressure-reducing valve, quad-check valve, burst disc, and relief valve. The helium pressure-reducing valve regulated the LM high-pressure helium, which forced the fuel and oxidizer into the engine.
The quad-check valve, used in both descent and ascent operations, prevented any backflow that might allow mixing of propellants. The burst disc acted as a seal, preventing propellant liquid or vapors from reaching the relief valve and, causing a corrosive reaction, worked in conjunction with the relief valve to prevent over pressurization of the system.
When the LM was unpressurized or the space suit umbilical cord was used, a suit loop pressure switch was incorporated in the system to assure maximum astronaut safety in the event of a torn suit.
Apollo 11’s touchdown on the moon was famously televised on July 20 and the post-lunar landing conversation between astronauts, “Cycle that Parker Valve,” was heard across the world. These valves were used to isolate the propellant feed systems, which were cycled open and closed immediately after landing. For years after, Parker Hannifin President and CEO Pat Parker would jokingly thank NASA and the astronauts for helping with Parker’s first global television advertisement from the moon.
Parker’s early work on the frontiers of space technology, made possible by our expert engineers and technicians, played a key role in the design, production, and flight of Apollo spacecraft. Parker equipment directly supported the success of Apollo missions as well as its astronaut’s safety.
The people of Parker Hannifin felt enormous pride during the years of the Apollo’s design, production, and flight. Today, remembering the part Parker played in this incredible achievement, we are still proud and humbled to be part of history.

ISO 14001 is recognized as the international standard for environmental management systems and provides organizations/businesses with criteria to follow, which will identify, control, and reduce their environmental impact. Becoming ISO 14001 certified has numerous benefits to businesses, sectors, and activities large or small. ISO 14001 is a voluntary standard that hundreds of thousands of companies worldwide have chosen to become certified in, uniting them in a global goal to reduce the environmental impacts created by companies and businesses, to preserve the natural Earth for future generations.
ISO 14001: was recently updated to ISO 14001: 2015, which introduces a few requirements to a universally beneficial certification. Key benefits of ISO 14001: 2015 include:
Parker reducing environmental impact
When becoming ISO 14001:2015 certified, Parker set ambitious goals. Parker's Precision Fluidics Division was getting two trash and one recycling pickup each week. The goal was to reverse those numbers. It was achieved in 18 months by training, raising awareness to all employees, increasing recycling bins throughout the facility with signs/labeling, and constant monitoring. Goals of this magnitude take time and planning, but the environmental rewards are immense.
Helping our customers and our team
Parker Precision Fluidics is a great example of a company set on reducing its environmental impact. A goal was set to improve the durability of product packaging and eliminate landfill waste at a customer location by introducing recyclable materials. A few simple adjustments were made such as using recyclable trays instead of bubble wrap, bubble bags, and foam inside each shipping container. The change resulted in energy savings, trash reduction, and reduction in the weight production needed of each box. The total result was almost 64,000 pieces of foam a year eliminated from landfill, 100% percent recyclable packaging, and a simpler tray packaging system.
Transitioning to a tray system reduced the weight the production team needs to handle when transporting from the production cell to shipping, providing a much-appreciated safety and ergonomic improvement. Another exciting feature of the new packaging is that our product is even more secure during shipment. Following the ISTA (International Safe Transit Association) test procedure, Parker validated the new packaging to be an improvement over the non-recycled foam — reducing the risk of shipping damage and increasing the product quality when it's received at our customers' locations.
Reduce, reuse and recycle
Another simple adjustment Parker Precision Fluidics has made is utilizing reusable packaging for component parts from repeat vendors.
The picture to the left is a rack of recycled plastic trays on Parker Precision Fluidics production floor. These trays come from various vendors that make parts for Parker. After the trays are empty, they are shipped back to the vendor and reused. This is a great example of a very simple way to reduce, reuse and recycle.
Parker Precision Fluidics is an ISO 14001: 2015 certified division of Parker Hannifin that has set both large and small goals that have been beneficial to the company as a whole, our customers, and best of all, the environment. The above examples show how ambitious yet simple goals can have great impacts. The main objective in ISO-14001: 2015 is having continuous improvement and never being content with what you have achieved.
The first step in becoming ISO 14001:2015 certified is to define your objective. What does your company want to achieve by getting this certification? Make sure you have the support of senior management. Take the time to review any existing processes and systems pertinent to environmental impact. If desired, third-party certifications are available that will conduct audits of your practices against the requirements standards. ISO does not perform certification.
