Knowing how cranes should be used, and how they should not be used, is critical to crane safety. Overload, side pull, limit switches, secondary braking devices, using the reverse direction for speed control, and daily inspections are surrounded by myth and mystery in the workplace.
The trend of using smaller operative corridors is seen in various surgical specialties. Neurosurgery has also recently embraced minimal access spine technique, and it has rapidly evolved over the past 2 decades. There has been a progression from needle access, small incisions with adaptation of the microscope, and automated percutaneous procedures to endoscopically and laparoscopically assisted procedures. More recently, new muscle-sparing technology has come into use with tubular access. This has now been adapted to the percutaneous placement of spinal instrumentation, including intervertebral spacers, rods, pedicle screws, facet screws, nucleus replacement devices, and artificial discs. New technologies involving hybrid procedures for the treatment of complex spine trauma are now on the horizon. Surgical corridors have been developed utilizing the interspinous space for X-STOP placement to treat lumbar stenosis in a minimally invasive fashion. The direct lateral retroperitoneal corridor has allowed for minimally invasive access to the anterior spine.
Earlier this year, an Arkansas trucking company became the latest to file a complaint against Navistar in federal court, arising out of the now familiar refrain that Navistar knew its 2010-2013 MaxxForce 11,13, and 15 Advanced EGR diesel engines were defectively designed and would prematurely fail, causing damage to the trucks and economic harm to the trucks' owners and lessees, as well as severely diminishing the value of the affected vehicles.
Sharing a machinery and equipment appraiser in a legal conflict is one of the more practical methods of reducing costs and discord. While the concept of shared experts is not new to legal proceedings concerning issues like mergers and collateral lending, I've been encouraged to see this refreshing trend gain momentum in family law cases as well.
I spent last week back east visiting my uncle and cousins at the Young family farm, where my uncle, who grew up there, now raises goats, grains and vegetables and boards horses on the property. My grandfather (Pappy) wasn't raised on a farm, but as a young man he built an old style dairy farm - a farm that not only made a living but fed his family as well. The dairy farm wasn't limited to milking cows; this family farm, like so many in that era, raised pigs, chickens, horses and grew corn, oats, rye; had a full vegetable garden as well as pasture land, an orchard and berry patch.
Every machinery and equipment appraiser is most likely familiar with the phone call - "I've got some equipment that I need to have appraised. How much will it cost?"
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.
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
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
Lubrication Institute provides many different types of courses for personnel, the following is a general outline of what we would present in our introductory benchmarking course
