Chock Talk - Train Stabilization with Railcar Holding Devices

Posted by Chelsea Finlay on Thu, Aug 25, 2016 @ 07:43 AM

Safety is undoubtedly the greatest concern for all rail facilities. A loading or unloading facility can quickly become a dangerous place when a railcar is not securely positioned. Soul Asylum said it best, “Runaway train never going back, wrong way on a one way track.” So how do you prevent a runaway train? With chocks!

Wood Pellet Exports Supply Europe's Inexhaustible Need

Posted by H&P Blog on Wed, Nov 18, 2015 @ 09:10 AM

The European Union plans to turn heavily towards using renewable energy in order to reduce emissions by 80 percent before 2050.  They are focused on reaching this goal, not just through the use of solar and wind but also wood pellets.  In numerous European countries, the use of wood pellets to produce electricity is becoming more commonplace.  Pellets are a by-product made from the sawdust, bark, chips and other pieces of scrap wood that are generated by the processing of trees into lumber.  The pieces are milled, dried and pressed into a pellet shape, and the lignin in the wood plasticizes to form a natural glue that allows a pellet to remain in one piece.

Maintain and Upgrade Railcar Dumpers for a Lifetime of Unloading

Posted by H&P Blog on Wed, Jul 22, 2015 @ 09:30 AM

Maintenance involves any actions that are necessary to conserve the condition of a piece of equipment to achieve its maximum useful life, while compensating for normal wear and tear. Routine operations are performed to both keep the device in working order and prevent trouble from arising. Different machines often have their own best practices and maintenance schedules that are unique to their own operation. Similarly, upgrades are the replacements of mechanical or electrical systems with a newer or better version, in order to bring the entire system up to date and improve its overall functionality.

Heyl & Patterson Compares Railcar Unloading Methods in World Coal

Posted by H&P Blog on Wed, Jun 24, 2015 @ 09:00 AM

Unloading railcars is usually accomplished in one of two ways:  a railcar dumper turns cars upside down in order to spill their contents, or bottom dump railcars drop their contents through chutes and gates. There are obvious differences between the two methods, but also some surprising similarities. Choosing between these systems calls for a number of factors to be considered, namely capital costs, maintenance, climate, versatility and economics.  Heyl & Patterson recently explored both sides of the matter in an article published in World Coal magazine's June 2015 issue, entitled "Which Unloading System?"

Heyl & Patterson Blog Celebrates Five Years

Posted by H&P Blog on Wed, Jun 17, 2015 @ 09:44 AM

The word "blog" is short for "web log," and is a website with posts providing commentary on a particular subject, much like a newspaper editorial column.  Blogging grew out of the burgeoning digital communities of the 1980s, which included Usenet, CompuServe and Bulletin Board Systems (BBS), and featured running commentary about various topics.  Early versions were a form of web diary that kept an intimate account of the authors' personal lives, and these ultimately evolved into the distinct class of online publishing we know today.  According to the web platform Technorati, there are now over 2.7 million blog posts published each day, and other recent statistics show that there are over 172 million Tumblr blogs and 75.8 million WordPress blogs in existence.

Unloading Wood Chips for the Production of Paper Pulp

Posted by H&P Blog on Wed, Mar 25, 2015 @ 09:48 AM

Even in today's "paperless" world, there continues to be a huge demand for paper.  Paper is made from wood pulp, which is also used to manufacture a wide variety of products from diapers to particle board to textiles. The pulp itself is the cellulose, lignin and hemicellulose components of wood fibers, which are separated from one another through steaming, cooking or mechanical grinding processes.  Most pulp is made from a mixture of sawmill residue, logs, wood chips and recycled paper, and it is interesting to note that practically all of the fibers that end up as pulp originally existed as trees.

Unloading Iron Ore by Rail

Posted by H&P Blog on Wed, Feb 04, 2015 @ 09:30 AM

Mining-OperationMan has been mining stone, metals and minerals since prehistoric times.  The world's oldest known mine site is located in Swaziland in Africa, where the first mining of metals was recorded via carbon dating as 43,000 BC.  Mining of metallic minerals occurred in ancient Egypt, Greece and the Roman Empire, and metals such as iron ore contributed to the industrial growth of Europe during the Middle Ages.  Iron is the fourth most abundant mineral in the Earth's crust, at about five percent, and it also represents 95 percent of all metal used in any given year.

A Scale Model Railcar Dumper Can Be Part of a Holiday Tradition

Posted by H&P Blog on Tue, Dec 23, 2014 @ 09:15 AM

Model trains are synonymous with the holiday season, often circling the base of a Christmas tree to the delight of children and parents alike.  These toys have existed since the first real railroads stretched across the early United States.  The earliest versions were made of cast iron, and some could even run on steam.  In the late 19th century, a German doll house manufacturer named Marklin sought to create an equivalent toy line for boys.  The company envisioned a constant revenue stream of add-ons that could be bought for years after the initial purchase.
