Traction and efficiency rule

You can find special-purpose vehicles for almost every task of landscape gardening – from riding lawn mowers to equipment trailers. These vehicles are normally designed for relatively flat and level fields, so an operator confronting a steep slope can pose a real challenge. A solution to this problem is a system similar to auto-leveling systems found in combine harvesters. For mowers, the chassis and mower unit remain parallel to the ground’s surface while the operator pod stays level. The result is safer and more comfortable mowing on slopes.

    Pinpoint power-loss problems

    Fluid power technology emphasizes the use of efficiencies as key figures of merit for many products across multiple marketplace segments. Such reasoning is sound, especially with the push to reduce energy consumption. However, efficiency is too simplistic a measure, and dare say, tends to be rather abused....More

    Virtual slip rings transmit power or signals across air gaps

    Power Coupling Units (PCUs) can inductively transfer dc signals across air gaps to interface with solenoids, digital or analog sensors, switches, relays, and actuators on rotary indexing tables or moving equipment. Sensor Coupling Units (SCUs) take it a step further — transferring power and data simultaneously to rotating or moving sensors....More

    Return-line hose snakes its way to pumps

    A big challenge to designing mobile equipment is finding a place to put all the hydraulic components. Locating cylinders is pretty straightforward, and valves and pumps need to be placed where they are accessible. But reservoirs are often placed anywhere on a machine that has a large enough void. This complicates routing of return lines because standard hydraulic hose may lack the flexibility to bend around obstacles....More

    Separator keeps air out of braking systems

    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....More

    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....More
