Forensic Clues: Agricultural Machinery - PTO Hazards

By: John Ryan, BSME, PE

Every year there are thousands of debilitating injuries and deaths on farms. Many of these are related to power take-off's (PTO's). PTO shafts are used to power various farming implements, from mowers, hay balers, augers, and many other types of farming machinery. The PTO shaft was invented in the 1930's. The PTO shaft is essentially a shaft powered by the tractor engine that rotates at high speeds, providing power for a wide array of implements. While this provides a convenient source of power to drive farm implements, serious accidents can occur due to entanglement in PTO's. PTO's must be properly equipped with guards including master shields which covers the stub shaft and universal joint. These shields prevent inadvertent contact with the rotating machinery. Contact with unshielded rotating PTO parts can instantly pull a person into the PTO, causing catastrophic damage.

After the Storm: Mitigating Losses Involving High-Technology Equipment Following a Flood

By: Envista Forensics - Bruce Swales

The role that water plays in our existence is well understood. Without it, most living things will rapidly wither and die. Equally catastrophic of course, are the consequences of too much water. Not only to living things, in terms of widespread flooding, but also in terms of damage to machinery and equipment from exposure to water.

Surface-Piercing Propellers

By: Paul Kamen

The art of positioning a propeller underneath a boat hull is not a new one. Designers and naval architects have been grappling with every aspect of the propulsion-by-propeller problem for generations, and the result has been the evolution of a well known set of standard and efficient solutions

Anti-Scale Valves

By: Dr.-Ing. Dirk A. Lindenbeck

In various industries there are valve applications where the standard valves used do not function satisfactorily. When scale is formed on the moving elements of ball valves or gate valves the consequence is either blocking of the valve movement or damage to the valve seats and consequent leaking through the valves

The Value of Lubricants and Lubrication Knowledge and Skills

By: John H. Marino

For me it is fascinating that in this highly competitive global marketplace, so many American companies lack the lubricants and lubrication knowledge or skills needed to protect, let alone achieve, the greatest return on their production machinery

What is most misunderstood and costly to your operation? Lubricants and Lubrication!

By: John H. Marino

Do you know that your equipment produces a profit on a thin film called lubricant? The most important but yet the most mismanaged in 99% of all companies is lubricants and/or lubrication. That’s why, it has been reported, that 60% to 70% of all mechanical failures are due to inadequate lubricants and lubrication practices
