Separator keeps air out of braking systems 1

Air or other gases entrapped in hydraulic circuits can cause erratic operation and lead to the formation of foam — which can be especially dangerous in braking systems. In a search for a reliable method to ensure that air would not get into the energy-assisted braking system of its machines, a manufacturer of mobile agricultural equipment found just that.

Cartridge valves add flexibility to excavators

Engcon AB, Strömsund, Sweden, is the world’s leading manufacturer of tilt rotators — attachments that are installed between an excavator’s boom and bucket to continuous 360° rotation and ±40° lateral pivoting of the bucket or other end tool. Engcon’s tilt rotators are equipped with a hydraulic motor for rotation and double-acting cylinders for optimized tilting force and even load distribution. Engcon´s tilt rotators can be used on most existing excavators and backhoe loaders within a weight range of 11⁄2 to 32 tons.

Quick couplings

Patented eSafe coupling combines high flow with low pressure drop in a durable compact envelope that has the dimensions of a standard coupling. Ergonomic easy-to-grip design and low connecting force allow convenient one-hand operation. Coupling vents downstream pressure before disconnection to eliminate hose whip and reduce noise. Complies with ISO 4414 and European EN 983 standards.

Hydraulic troubleshooting video

Last year Webtec sponsored the first “Introduction to hydraulic fault prevention and diagnostics” day at the National Fluid Power Centre, in Worksop, England. The day provided opportunities to participate in hands-on workshops, and hear a number of speakers. Webtec recorded John Savage’s, Director of the NFPC, seminar on hydraulic fault-prevention.

NFPA announces 2013 Fluid Power Systems Conference

Registration is opening soon for the 2013 Fluid Power Systems Conference, formerly known as the Energy Efficient Hydraulics and Pneumatics Conference, November 19- 21, 2013 at the Doubletree Hotel, Rosemont, Illinois.

Hosted by the International Fluid Power Society (IFPS), the FPDA Motion and Control Network (FPDA), and the National Fluid Power Association (NFPA), this two-day educational conference will focus on:

Beauty isn’t just skin deep

Unless you build hydraulic test stands, you probably rarely see bright, shiny new ones. But you’ll find just that in Fountain Inn, S. C. As part of the grand opening for its new hydraulics campus in Fountain Inn, Bosch Rexroth US unveiled a new test stand for evaluating its Rineer brand of vane type variable-displacement hydraulic motors.

Customized motors increase speed by 40%

Work output in a potash mine requires machines with high mobility and reliability. Potash is a salt containing a high concentration of water-soluble potassium, so it is widely used in fertilizer. In response to the world’s increased demand for potash, Canada’s PotashCorp., Saskatoon, SK (PCS) stepped up production at its Rocanville, SK mining facility with an X CEL 44 continuous bore mining machine.

Class 2 Heavy Duty Cylinders

Heavy-duty  cylinders have cast-iron end caps for hydraulic or air pressure to 450 psi. These cylinders incorporate recessed gasketed tube seals and piston o-ring as standard features. Each assembly is prelubricated and 100% pressure tested. More than five mounting styles in 11 standard bores from 2½ to 6 in.

Safety with explosion-proof air springs

ContiTech Air Spring Systems released a new line of ATEX-certified air actuators, making them suitable for explosion-prone areas of industrial applications. As Category 2 and 3 equipment (Equipment Group II), they can be used in atmospheres containing volatile gas or dust.

Simulation table shrinks design-to-market window

Kemflo International Co. Ltd., Taiwan, entered the automotive accessories market in 2009 by acquiring U.S.-based Yakima Products, a maker of car racks and cargo boxes for carrying skis, bikes, and snow boards.

High-strength steel is made for hydraulic cylinders

Ovako North America Inc., Ft. Mill, S.C., offers its Ovahyd 600, 650, and 700 hydraulic steels, which were developed mainly for the manufacture of highly stressed hydraulic components, such as cylinder tubes and piston rods. The steels have impact strengths of 600, 650, and 700 MPa, respectively, and come in bars and seamless tubes. Ovahyd 600 comes in bar ODs from 24 to 160 mm and tubes from 56- to 205-mm OD with 40-mm wall thickness. The 650 and 700 grades come in bar ODs from 24 to 75 mm and tube ODs from 55 to 205 mm with 25-mm wall thickness.
