November 2011 The LinsiTrak can mow any lawn, even on the most extreme slopes. Company owner and engineer Werner Müller explains his hydrostatic drive concept. In landscape gardening you will find special-purpose vehicles for almost every task – from the riding lawn mower to the equipment trailer. And anyone confronted with steep slopes faces a [...]
July 2011 A uniform concept for hydraulic and electrical components. A modern production strategy nudges the new series of Dynapac paving machines into the fast lane. Each and every year, ten thousands of kilometers of streets and roads are built around the world. But there’s one machine that has to finish its work before vehicles [...]
July 2011 Wherever it’s necessary to dig, lift or tow, that’s where mobile working machines are needed. A look inside will show that hydraulic power is behind the many different movements. But how are these motions coordinated, and which mobile control concept is suitable for which application? Mobile hydraulic systems have to be not only [...]
March 2011 Special tooth geometry reduces noise in external gear pumps. The SILENCE PLUS innovation offers numerous advantages in practice and can reduce system costs for customers. by Christian Böhmcker, Marc Lätzel and Dietmar Schwuchow, Bosch Rexroth AG For decades now external gear pumps have demonstrated their usefulness as rugged and economical workhorses. Their primary [...]
October 2010 Electric, hydraulic, pneumatic: How do the different types of drives work, and which drives are the best choice for a specific purpose. Electric drives How they work Electrical energy is converted into mechanical kinetic energy. Two magnetic fields, one each at a stator and a rotor, interact. As the magnetic fields constantly try [...]
April 2010 Modern deep drilling rigs with extensive hydraulic equipment can sink wells quickly, quietly and safely. In nine years the oil reserves in the U.S.A. will be exhausted. That was the forecast made by the United States Geological Survey in the year 1919. Neither does anyone today know how much fossil energy actually still [...]
April 2010 The market for mobile working machines is facing massive challenges. By keeping an eye on the big picture, though, Rexroth systems are helping, even today, to master those tasks. Manufacturers of mobile working machines are concerned by four major aspects: ♦ energy ♦ the environment ♦ costs ♦ functionality. Upcoming statutory requirements such [...]
April 2010 How diggers, loaders and tracked vehicles will work tomorrow. Would Rudolf Diesel have been in the mood for partying if he’d been able to attend his 150th birthday not too long ago? His spontaneous combustion engines, patented in 1893, are coming under considerable pressure. The makers of passenger cars and trucks, and the [...]

This was the somewhat surprising result of a poll of 2,600 companies, conducted by Simon Kucher & Partners corporate consultants. In spite of declines in orders received and the credit crunch, [...]
The new EU Machinery Directive went into force at the end of 2009 and imposed new safety requirements. How should these regulations actually be implemented when designing machine controls? A guideline. On December 29, 2009, the new 2006/42/EC Machinery Directive went into effect. In addition, a new standard on functional safety, ISO 13849-1, became binding [...]
