Nearly every equipment operator has found themselves operating in muddy, mucky conditions whether working on ditches, drainage fields, ponds or other waterlogged environments. Experienced operators know how these harsh conditions can cause wear and tear on their excavator's attachments, shortening the life of their equipment and resulting in costly downtime. For the Wisconsin Department of Natural Resources (Wisconsin DNR), PowerGrip is just the tool to overcome these job site obstacles. PowerGrip, a versatile, durable multi-purpose bucket with enclosed rotary actuator hinge technology, consistently delivers outstanding performance without suffering the downtime and maintenance issues experienced with cylinder-style buckets.
Bill Ryan, operations team supervisor at the Wisconsin DNR, has witnessed the durability and reliability of PowerGrip in the field. His skilled team restores miles of fragile trout stream habitat in Wisconsin, which involves bringing back the natural features of the stream that is critical to trout viability such as riffles, pools, meanders and woody debris. The habitat around the stream also must be restored often requiring difficult bank sloping and vegetation removal and replacement. Over a year ago, Wisconsin DNR replaced a cylinder-style jaw bucket on their CAT 320C with a PowerGrip to alleviate the service and maintenance issues they were previously having with the cylinder-style jaw bucket. They also found PowerGrip to be a safer solution as there are fewer external moving parts that they need to contend with, resulting in greater productivity.
"We replaced our cylinder-style jaw bucket with a PowerGrip and couldn’t be happier. Due to the enclosed actuator hinge mechanism, we haven’t had to do anything with it, except complete the tasks on hand. PowerGrip has proved to be safer, more reliable and is extremely durable,”

An innovative operation design solution
The harsh conditions in and around the stream often wreak havoc on heavy equipment and attachments. PowerGrip is equipped with a durable, enclosed rotary actuator hinge that’s ideally suited for working in muddy, mucky conditions. With the rotary actuator hinge technology offering 120 degrees of jaw movement, there are no exposed cylinders and rods in the bucket shell or clam that can become polluted with debris, leading to attachment malfunctions. The rotating movement is generated by the massive rotating pivot point between the jaw and back of bucket with Parker’s Helac sliding spline operating technology, which converts linear piston motion into powerful shaft rotation. The end caps, seals and bearings work in unison to keep debris and contaminants out of the inner workings of the actuator, prolonging life and reducing required maintenance. High strength, abrasion resistant steel is used throughout for added durability. In over a year, Wisconsin DNR hasn’t had to do any maintenance to PowerGrip, allowing them to get more work done in less time.
When dealing with the various obstacles inherent in restoring a trout stream, sloping a ditch or building a retention pond, it is imperative to have an adaptable multi-purpose tool that can change jobs on the fly. PowerGrip has been engineered with the flexibility to function as a trenching, grading or clamshell bucket and for gripping and loading. The inherent flexibility of our actuators allows the Wisconsin DNR to keep PowerGrip on their machine 80 to 85 percent of the time, year-round. PowerGrip’s versatility allows operators to accomplish a wide variety of tasks without having to change machines or attachments. When selecting the PowerGrip, the Wisconsin DNR went with the PG-08 product model that’s available for 20-ton machines. PowerGrip buckets are available in three sizes with bucket width ranges from 24 to 48 inches in the trenching profiles and 48 or 60 inches in ditching profiles.
Time is preciousWhether you are doing demolition work, road construction, pond building, site-preparation or restoring miles of trout stream; every second counts. Maximizing productivity can prove to be much more than an organizational objective towards profitability, in the case of restoring a fraye trout stream ecosystem - it can prove to be the difference between survival and extinction. PowerGrip increases the tasks a single machine can perform, reducing the number of dedicated-task machines needed on a job site. PowerGrip can do everything a thumb can do, and more. And it’s ready-to-use, pin-on attachment that’s easier to install and operate. There’s no welding, fabrication or in-field measurement needed to install or remove the attachment, saving you valuable time and money.

Though gas-powered, internal combustion engine driven vehicles have been the norm in the automotive industry for over 100 years, electrification is growing. The traditional engine design was efficient, reliable, and easy to use, but gasoline powered vehicles are loud, dirty, and harmful to the environment. Given these drawbacks, electric vehicles have started to gain market share in commercial and personal markets. Public transportation is moving toward electrification at a faster pace than other markets, spurred by the deployment of electric vehicles in China.
The eHPS is ideal for buses and large commercial vehicles that require large amounts of hydraulic power for steering assistance, but also necessitate the quiet operation of an electric system. In addition, the eHPS has IP67 protection, is tested to SAE J1455 vehicle standards, and designed to ISO 16750 standards, making it ideal for replacement applications. Electrification is the future of the automotive industry, and public transit is leading the charge.

Phil Meyer, operations manager of the Whitman County Public Works Department, in Washington State, is tireless in his search for the right tools to help his 42-person team maintain over 1,900 miles of roads and 360 bridges and large structures in Southeastern Washington. The department has a daunting workload and inclement weather that can border on the extreme, productivity, durability and versatility are critical requirements of the equipment used at Whitman County. Typical projects include ditching to maintain flow lines, culvert maintenance, placing rip-rap, brush removal, bridge demolition, gabion basket installation, sloping and more.
The seven PowerTilts and their PowerGrip have been important assets for the Whitman County Public Works department. With PowerTilt and PowerGrip, the department accomplishes most tasks 25 to 50 percent faster. The Whitman County Public Works department has even recommended PowerTilt and PowerGrip to other local agencies such as the Washington State Department of Transportation and the North Latah County Highway Department in Idaho.
PowerTilt uses Parker’s innovative sliding-spline operating technology to convert linear piston motion into powerful shaft rotation. Each actuator is composed of a housing and two moving parts — the central shaft and piston. As hydraulic pressure is applied, the piston is displaced axially, while the helical gearing on the piston outer diameter and housing’s ring gear cause the simultaneous rotation of the piston. PowerTilt's end caps, seals and bearings all work in tandem to keep debris and other contaminants out of the inner workings of the actuator.
Over a decade of research, innovation and engineering has gone into making the PowerTilt and PowerGrip attachments integral solutions for work site efficiency. PowerTilt’s robust design has allowed Whitman County Public Works to keep a PowerTilt on their machine 100 percent of the time, year-round.
