Cylindrical reservoir breaks from convention

Mon, 07 May 2012 18:20:00 +0000

The Cyclone reservoir has a cylindrical shape, and was originally developed and patented for use in hydraulic fan drives for mobile equipment by Price Engineering, Hartland, Wis. Now available for general application, officials at Price Engineering say the Cyclone reservoir reduces fluid volume and associated costs up to 95%.

The dramatically smaller size makes space available for mounting other components in a machine. It also reduces weight and is more environmentally friendly because less fluid is needed in the hydraulic system.

Mired in the Muck

Mon, 07 May 2012 17:49:00 +0000

Menzi Muck AG, Widnau, Switzerland, makes all-terrain excavators named after a legendary elf, Mr. Muck, known as “the little man who does everything.” Menzi Mucks allow each leg or wheel to be raised, lowered, extended, retracted, or moved in or spread out so the operator can adjust the working base of the machine to conform to the terrain. This control provides extreme maneuverability and remarkable flexibility, stability, and safety in operation.

Simulation results for leakage parameters

Fri, 04 May 2012 18:07:00 +0000

The leakage input parameter was set to 2.75 in.3/sec for all the previous investigations. Now it is going to be seen how this value is only an estimate of the peak leakage that results from the simulation. Furthermore, the simulated peak leakage is affected by the amount of overlap that is used for any specific computer run.

Rock crusher overheating and shutting down

By Robert J. Sheaf, Jr., CFC Solar

An automotive company built an assembly plant on land that had a limestone base. Research found that if the limestone was removed, crushed and re-laid, the plant stability and harmonics would be improved to a point that would offset the cost of crushing the limestone.
