Hydraulic rescue spreaders are used by emergency response personnel to extricate occupants from a vehicle crash. A lighter and more portable rescue spreader is required for better usability and to enable utilization in a variety of scenarios. To meet this requirement, topological synthesis, dimensional synthesis, and an optimization were used to develop a solution linkage. The topological synth...

An alternative method for fertilizer spread pattern determination was developed based on predicting where individual fertilizer particles land on the ground, in contrast to the traditional method of collecting the particles in bins (ASAE Standard S341.2). A small broadcast granular fertilizer spreader (Lowery 300) was equipped with an optical sensor designed to measure the velocity and diameter...

Abstract The effect of distance between the primary pivots on stability two-chain suspension arrangement a load has been explored. Based concept and methodology for calculating static stability, developed in previous works, it shown that with narrow placement is generally less stable than normal arrangement. reduced such system primarily associated decrease length base triangle (ST) inside whic...
