IFPE Download: New hydraulic drives for excavators
Comer Industries, Reggiolo, Italy, recently expanded its product range with a line of purpose-built track and slew drives specifically for the excavator market. The PGR 18000 series is for 80 to 100 ton size machines, and is built to meet the highest performance and reliability requirements in the toughest working conditions, said company officials. They […]
NFPA hosts Research Symposium at IFPE
The NFPA will present its IFPE Research Symposium March 11-13 during lunch presentations. This program showcases the latest fluid power research being performed at U.S. universities with funding provided by a new program within the U.S. Department of Energy to improve the energy efficiency of hydraulic systems on off-road vehicles. The Symposium will be held from […]
What makes mobile hydraulics different from industrial hydraulics?
The need for lower weight, size and costs mean that mobile machinery often sets the stage for power density improvements in fluid power. All hydraulic machinery should be similar in scope and design, one would think. After all, the point of fluid power is to transmit force. Why should any given mobile machine be vastly […]
New design overcomes piston-pump limitations
Piston pumps and motors have been on the market for many years, and they are arguably one of the most important components in many hydraulic circuits. The basic design behind a conventional piston pump usually has seven or nine pistons that convert mechanical torque into oil pressure. In a piston motor, the process is reversed. […]
Linde Hydraulics opens new plant in Weifang, China
In an official ceremony, Linde Hydraulics GmbH & Co. KG opened its newly-built production plant in Weifang, China. The global project team took only two years for completion from concept to opening of this 36,000m2 facility which encompasses an administration building along with 25,000m2 production halls. The new facility consolidates processes previously housed in several […]

Modular pumps offer numerous control options
The LH30VO Series 20 of hydraulic pumps from Liebherr Components complements the company’s existing portfolio of hydraulic pumps in the medium pressure range. It is based on a modular system that can be adapted flexibly to customer requirements and enable various applications in mobile and stationary hydraulics. The swashplate-type axial-piston unit features a compact housing […]
Hydraulic travel drive controls tire pressure
Controlling the tire pressure of crop harvesters has numerous advantages, due to different vehicle handling characteristics whether operating on roads or in fields. To address the need, Bosch Rexroth introduced the GFT 8150 TIS (Tire Inflation System), which enables dynamically optimized tire pressure in machines, at Agritechnica 2019 in Hannover, Germany. The new GFT 8150 […]
What are PTO through-drive motors?
By Josh Cosford, Contributing Editor If you’ve spent any reasonable amount of time working on or around mobile machinery, you’re very familiar with PTO-driven machinery, including the hydraulic pump. The PTO shaft exiting the rear of a farm tractor is used to power mechanical implements through a drive shaft, such as bailers or mowers, themselves […]
