While the National Association of Manufacturers’ annual Labor Day Report is good news for manufacturers, soaring energy costs are hurting manufacturing workers at the pump and in their paychecks. “The report provides a snapshot of the U.S. economic performance over the past year,” said John Engler, president and CEO of NAM. Manufacturing production increased at its fastest pace in six years and jobs on the factory floor have posted their strongest gains since 1998. “But while workers’ total compensation has continued to outpace inflation, wages have not,” Huether said. “Surging energy prices have propelled inflation at a faster pace than workers’ take-home pay and have resulted in declines in real wages for working Americans.” “Over the past year energy prices have risen 23% due to increased global demand, limited domestic supplies, natural disasters and global instability,” Engler said.

We could say the overriding preventative maintenance motivation can currently be simply characterized as "preserve equipment." Almost without fail, our current maintenance planning process starts directly with the equipment, and its sole purpose is to specify actions required to "keep it running." But recognize from the outset that Reliability-Centered Maintenance is not just another cleverly ...

While there's a lot to be said for continuous improvement, every once in a while it's nice to stop, look around and survey what has been achieved. At manufacturing facilities such as Chrysler's Belvidere, IL assembly plant, such a survey resulted in its selection as PLANT ENGINEERING's Top Plant for 2005.

In an effort to build a link between the operations and maintenance side of plant operations, Invensys Process Systems announced Oct. 5 its new asset performance management solution designed to put both sides of the plant productivity equation together with the same information. “I believe this is a pivotal day for Invensys Process Systems,” said president Mike Caliel. “What I think you’ll see from us is a more continuous rhythm as we build this model of asset performance management.” Caliel said the new asset performance solution allows both operations and maintenance to operate off the same platform, and in a cooperative fashion.
Review tank designs first I read PLANT ENGINEERING every month. There is always good information. However, as I read the May 2005 Solutions tip titled "Changing hoses and fittings" I was alarmed. Though your "Safety First..." disclaimer does generically cover most concerns with this idea, it does not cover the mechanical design of the tank to which someone might apply this tip.
Applying drill pressure Problem : Drilling holes in awkward positions is difficult because it is hard to apply much force with one hand. Is there an aid available? Solution : Make a manual assist by combining a handle bar, chain, and hooking arrangement. Applying pressure on the drill with the handle bar greatly improves drilling ease. This tip was originally published in September 1997.

To learn more about the program call Robert Asdal at 973-267-9700 x13. Hydraulic Institute pumplearning.org Write 301 on PE card Hose assembly safety Hose Assembly Safety Program is a free service to industry.

Back in the late 1950s, air-conditioning had not yet become a routine part of building construction. So it wasn't a consideration when the L-shaped Building 101 on Boeing's St. Louis campus was first constructed in 1958, nor when a second phase was added in 1962. In 2001, however, Boeing began taking a fresh look at Building 101.

Workers protest Incentive plan deemed unfair To say that the workforce objected to the company's recently announced incentive plan would be the understatement of the year. The union kept haranguing management with worker protests of unfairness. Since the plan was part and parcel of the collective bargaining agreement, Union Delegate Frank Delgrasso demanded detailed information related to the time-study analysis on which it was presumably based. Although annoyed by what he regarded as harassment, Plant Manager Al Levinson complied. His compliance didn't satisfy Delgrasso. He persisted in claiming that there were too many loopholes and too much confusion. As patiently as possible, Levinson tried to explain every item presented to the union delegate's satisfaction. Delgrasso kept shaking his head.
Regular out sick Can management pick sub? Was it a virus, or what? Maintenance Supervisor Oscar Coleman had no idea.

She sighed.

Warren Leopold interview with Mark Baker
Since the Clean Air Act (CAA) was enacted in 1970, and amended in 1977, and again in 1990, the Environmental Protection Agency (EPA) has continued to tighten the limits on emissions of Hazardous Air Pollutants (HAP) and Volatile Organic Compounds (VOC). Fortunately, the development of new air pollution control technologies has kept pace with changing EPA regulations.

Making round holes • Problem: When drilling through thin sheet metal, often the hole ends up out-of-round and a bolt will not pass. How can the hole be made round enough to pass a bolt? • Solution: To make the hole round, run the drill bit through the hole until the shank of the drill bit is in the sheet metal. This rounds out the hole to let a bolt pass through. Contributor: Wayne E.
The cost of leaking steam traps can be huge. If steam, for example, costs $5/1000 lb, a leaking trap with a 1/8 in. orifice in a 50-psi system would waste 29.8 lb/hr, or 260,333 lb/yr. The energy waste from this trap would be $1302 annually. In a system with 100 traps and an estimated failure rate of 25%, the annual cost would be $32,541.
Factory managers who need to tighten their budgets for operating supplies will find the going gets tougher in 2003. That's because the margin cushion that suppliers built this past year has been rapidly disappearing. Increases in the costs of raw materials, specifically steel and petroleum-related products, are squeezing producers.
Plant engineers who buy operating materials and supplies need to watch two products carefully. Three months ago, the lubricating oils and greases (SIC 2992) industry and the wood pallets and skids (SIC 2448) industry were registering declines - and in the case of oils, rapid declines in their average production costs.
Regular readers of this column may notice that the demand data in the Plant Engineering operating materials and supplies table have been revised downward. In some cases, the revisions are significant. For example, in the 12 months ending July 2001, end-market demand for lubricating oils was revised from 7.
