Hydraulic motors are rotary actuators that convert hydraulic energy into mechanical torque. Using the pressure and flow provided by the hydraulic pump, hydraulic motors rotate to pull, drive or winch external loads on various hydraulic machines spanning construction equipment to food mixers. The three most common constructions of hydraulic motors are the gear, vane and […]

PVG 48 pre-compensated proportional control valve for mobile machinery
Danfoss Power Solutions has extended its PVG valve portfolio with the addition of PVG 48, a pre-compensated proportional control valve for mobile machinery. Designed for applications requiring flow rates of up to 180 liters per minute (47.6 gallons per minute), PVG 48 provides customers with a right-sized option between the existing PVG 32 and PVG […]
Check valves serve critical role in work trucks with aerial work platforms
Even when workers follow job site safety protocols to a T, emergencies can happen. And when working with large, powerful machines in dangerous or challenging environments, things can become catastrophic quickly. However, there is one small but critical machine component that can help minimize equipment damage, limit project downtime and keep workers safe – the […]
Hydraulics that “eats trees” — but in a good way
Mobile hydraulics is often called on for tough forestry jobs, and Diamond Mowers’ new Belt Drive Disc Mulcher is suited for contractors and mulching professionals who specialize in land clearing, vegetation and forestry management, and pasture reclamation. It features increased torque to obliterate anything in its path without slowing down, recovers twice as fast as […]

These highly durable and energy-efficient solutions will be showcased on stand N:03d at the Swedish Forestry Expo from June 1-3, 2023. Equipment used in […]
Parker’s disengageable twin flow pump saves fuel and reduces life cycle costs
The Pump & Motor Division Europe of Parker Hannifin has announced the launch of its new disengageable twin flow truck pump, the F4 series, as an innovation for the mobile hydraulics market. The new F4 hydraulic pump merges technology from the successful F2 twin flow pump and F3 axial piston fixed pump series, resulting in […]
A new “Twiist” on position transducer design measures multiple data points
After 10 years of research, Gefran, an Italian sensor and control company, has launched its Twiist contactless linear position transducer to the North American market. The transducer not only measures position but can also measure temperature, velocity, acceleration, and tilt angle. “There are several products on the market that measure position and Gefran has them […]
Liebherr expands axial-piston offerings
At this year’s IFPE 2023 show, Liebherr Components presented its expanded line of axial piston pumps — including two new pumps with nine nominal sizes. To keep pace with ever-increasing demands for availability and durability, the new size 550 cc was developed in close cooperation with customers for use under extreme working conditions, according to […]
New submerged HPUs give boat lifts a boost
In recreational boating, hydraulic power units (HPUs) provide the muscle behind critical operating machinery used to transport, launch, or secure small craft, including lifts, trailers, and jacks. For boat lifts alone, OEMs produce a variety of configurations, such as bottom standing, piling mount, floating, and shore mounted. These machines and configurations rely on hydraulic systems […]
IFPE 2023 wrap-up: Axial-piston variable motor for hydrostatic drivetrains
As it highlighted its system options along with its technologies for electrification at IFPE last month, Bosch Rexroth showcased new and legacy products that can optimize modern machines. One such component was its A36VM axial piston variable motor, which was developed specifically for hydrostatic drivetrains. It allows greater tractive force and speed for mobile machines. […]
