Bosch Rexroth is showing its electronic Diesel Hydraulic Control (DHC) system at CONEXPO/IFPE, which the company said provides higher dynamics at lower engine speeds.
The Fairfax County Solid Waste Program in Virginia is using a Bosch Rexroth parallel hydrostatic regenerative braking system in the county’s first hydraulic hybrid trash and recycling vehicle.
Rexroth’s three practically-oriented mobile hydraulics component sets—with corresponding documents for instructors and students—illustrates fundamental control principles for mobile hydraulics.
The Center for Compact and Efficient Fluid Power, now in it’s 5th year, has been a nice success story for the fluid power industry. Funded in part by the National Science Foundation, the Center has among its goals the research and development of efficient components, compact power supplies, and compact energy storage.
Eaton announced that customers of its hybrid systems have accumulated more than 100 million miles of service, reducing fuel consumption by 4 million gallons of diesel fuel and emissions by 40,000 metric tons.
Altair Engineering has selected Parker Hannifin’s series hybrid hydraulic drive system for its BUSolutions project. The system will enable the new advanced bus platform to achieve 45-70% increased fuel economy over average diesel powertrains and more than double the fuel economy improvement of hybrid-electrics.
HydraForce has collaborated with Famic Technologies Inc. to incorporate their valve library into Famic’s Automation Studio software.
Designing a hydraulic control system involves several design considerations and tradeoffs. Key among them are selecting the proper system components and setting up the motion controller with the proper control algorithm.
Protective covers for hydraulic hoses are still used to protect hoses on mobile construction and mining equipment. However, with the need for higher-pressure systems and more compact machine designs, there is an increasing need for ways to safely protect machine operators and personnel from catastrophic hydraulic hose failure.
The combination of an AMLOK rod lock, rod and rod eye, plus cartridge valves and bodies supplied by Hydrotech engineering staff resulted in a gate lift system that mechanically holds securely at any angle, with rod release occurring on operator command.
