This isn't grandma's greenhouse.

Five years in the making, Original Harvest Farms new 3,000-square-foot operation redefines what an organic farm can be.

It doesn't just run on sun, soil, water and sweat. Hamilton's V-Groove casters, which power a mobile and raised plant bed system, boost the company's growing space by 30 percent.

A square foot is the most expensive part of this highly advanced greenhouse and growing system, said Graham Boothby, co-founder and president of Original Harvest Farms. By putting our beds on casters, we increased our growing area by 500 feet.

Year round, that adds up to thousands of pounds of additional fresh produce from tangy mustard greens to edible flowers and a dozen varieties of lettuce.

Rooted in Efficiency

While the concept might sound complex, it's remarkably simple. In the average greenhouse, aisles divide plant beds so employees can access the produce.

With Hamilton, Original Harvest Farms cuts out what Boothby calls wasted space. If I'm not standing, walking or working in an area at any given moment, I want to be growing there.

Now we simply move a row to the side to create an aisle for us to till soil, plant or harvest, he said. And even though a row weighs about 2 tons, the casters allow two people to move them with ease.

As for why the company didn't just build a bigger greenhouse?

At this size, we're a self sufficient, zero-net energy operation, he said. If we added just a few hundred feet, we'd increase our construction costs, carbon footprint, and the amount of electricity we’d need to offset.

With the first building up and running, Original Harvest Farms is already looking to the future.

We're planning expansions to Brooklyn, Chicago and Detroit, said Boothby. And you can bet Hamilton's part of our growth plan.

So, you just bought a new set of casters for a cart. Now what?

The obvious answer is to place them on the four corners of the cart, but we don’t recommend that because it can make the cart harder to maneuver, and it may create a dangerous trip hazard.

To score points with plant safety managers, place the swivel casters at the steering/pushing end, and far enough forward from the end to avoid conflicting with the feet of anyone pushing the cart. Consider the entire swivel envelope of the casters when positioning them. Keeping swivel casters at the side edges will maximize lateral stability.

Rigid casters should also be mounted at the outside edges, but approximately ¼ of the way back from the front of the cart. This compromises some of the stability but greatly enhances the maneuverability.

Should the anticipated load be somewhat tall or the cart have a high center of gravity, then placing the rigid casters at the end may make sense. Just remember that it will be much harder to maneuver the cart, particularly in tight places.

We created a handy graphic that covers the most typical cart applications for (3) standard platform sizes. But, if you want to save yourself the effort, pick out one of our carts at the new, and we’ll do the mounting for you.

Have questions about placing casters? Drop us a line. We’ll be happy to help.

The invention of the wheel? Awesome. Winning your fantasy football match-up? That’s debatable. Truth is, we’re all guilty of overusing the word “awesome,” to the point where it’s become about as meaningless as celebrity marriages.

Jill Shargaa, comedian and one heck of a speaker, lays out her plan to save the word (and much, much more) in this AWESOME TED Talk. Watch it, get inspired and help restore “awesome” to its glory days.

You’ve fired off emails and left voicemails with the receptionist, only to be met with radio silence. We’ve all been there – trying (and failing) to track down a sales prospect who’s always out in the field.

Fear not. With these three tips, you can up your chances of getting a call back from an elusive sales lead.

Do Your Homework.

You know the ins and outs of his factory operation, but do you know he loves canoeing and his son plays football at Kansas State? Use this information to make yourself memorable and break through the cruft in his inbox. To up your sleuthing game, try connecting with your prospects on LinkedIn, or following them on Twitter.

Use the Right Dose of Humor.

We all have bad days, and some times, all it takes is a well-timed laugh to make everything OK. We don’t mean overdo it with a raunchy joke, but if you both share the same devotion for a winless sports team, now might be a great time to poke fun.

Reverse Engineer Your Question.

Put yourself in their shoes. Respond to your email the way you think the prospect would. If it’s too wordy or taking forever to get to the point, chances are your question is too complicated. Keep it simple and easy to answer. And remember, it doesn’t all have to be work related. Hint: humor!

Lastly, don’t be discouraged. It might take a few broken casters (non-Hamilton, of course) before the prospect even thinks about calling you back. But with these tips, you’ll stay top of mind when that time comes.

Before the Navy plunks down billions on new ships, it tests how they float in 12-million gallon indoor ocean.

Inside the football field-sized basin, scaled-down fiberglass models – about the size of a canoe – feel the wrath of the ocean.

Equipped with 216 electronically controlled wave boards, it precisely simulates the conditions of all seven seas – from calm to typhoon-like.

Floating isn’t the only test on deck at the Naval Surface Warfare Center, either. How do ships hold up under pressure with a full tank versus running on empty? Can sailors handle their duties without losing their lunch?

These are the questions Naval engineers hope to answer in about six weeks of trials per vessel.

Production time? Not so fast. According to Smithsonian Mag, a recently tested submarine won’t hit the high seas until 2031. And when that time comes, we’ll be standing by dockside with the toughest casters on the planet.

The oil industry is booming with Hamilton and Frank’s International on the pipelines.

A world leader in oilfield services, Frank’s chose us to build a 25-foot-long trailer to haul diesel and hydraulic hammers. They’re used to drive pipe into the ground as the first stage of new oil well installations.

“Because the hammers are longer than they are wide, we couldn’t load them onto forklifts to carry them into the maintenance area of the workshop bay,” said Ray Barrileaux, assistant operations manager at Frank’s International.

While the company builds a brand-new facility, it currently operates in a temporary shop with height restrictions. Our extra-long trailer bypasses those height constraints by carting hammers in and out of the work bay.

“We weren’t about to let a few low ceilings sink our operation,” said Barrileaux. “With Hamilton’s help, we’re able to help our customers keep the oil flowing.”

Tech Specs

  • All steel, caster-steer trailer
  • Size: 72” wide by 300” long with 18” deck height
  • Load capacity: 40,000 pounds
  • Running gear: Two dual-wheel swivel casters with 12” by 4” Superlast polyurethane wheels; four dual-mounted, 15” by 9” press-on polyurethane wheels
  • Eight lashing rings evenly spaced along each frame
  • Loop-type towing tongue

We don’t build bridges, but our casters play a key role in their construction at the factory level. That’s why they fascinate us, especially ones that seem to defy gravity.

Here’s the scoop behind some of the world’s most incredible bridges:

The Second Penang Bridge – Southeast Asia

On a good day, it takes drivers more than 20 minutes to cross South China’s 15-mile-long bridge. To construct it, engineers bored steel piles more than 400 feet into the sea. As for the bridge’s signature curvy looks? “To prevent drivers from getting drowsy, discourage speeding and improve road concentration,” said construction director Hamizol Ngah.

Gateshead Millennium Bridge - England

It seems plucked from a galaxy far, far away. Locals call it the “Blinking Eye Bridge” because of its titled appearance when it opens 40 degrees to allow boats to pass through. But the coolest detail? During construction in 2000, the world’s largest floating crane, the Asian Hercules II, lifted the entire bridge into place in one piece.

Baakenhafen Bridge – Hamburg, Germany

Since opening in August 2013, this German landmark has won just about every engineering award in Europe. Its sleek and curved orthotropic deck, supports weight and helps contribute to the bridge’s overall load-bearing capacity. What’s more, a 98-foot-wide block in the middle can be removed to accommodate über-tall ships that need to pass through. Das genius!

Lumberjacks are becoming extinct. Watch this machine turn a 30-foot-tall spruce into sawdust in seconds, and you’ll understand why.

Manufactured by Canada’s Denis Cimaf, the excavator mulcher clears out brush in a hurry – from roadside pruning to making way for a new Costco.

And while it doesn’t run on casters, you’ll find Hamilton inside similar factories that manufacture heavy duty lumber equipment.

At some point in your life a Type A boss has told you to multitask to get more done. But instead of turning you into a productivity ninja, studies show that multitasking is giant waste of time.

“For tasks that are at all complicated, no matter how good you have become at multitasking, you’re still going to suffer hits against your performance. You will be worse compared to if you were actually concentrating from start to finish on the task,” said David Meyer, scientist at the University of Michigan.

Concentrating on a single task at one time isn’t the only way to boost productivity, either. Because our brains can only focus for a limited amount of time, experts recommend working in chunks.

Here’s what else you might try to be more productive:

  • Reward yourself! Check your fantasy football scores AFTER you’ve wrapped up that PowerPoint presentation.
  • Get away. Too many distractions at the office? Take a walk outside, or find a nice cubby to call your own while you bang out a few sales calls.
  • Music to “zone out” to. This might come down to personal preference, but loud music with heavy lyrics can become a distraction. Instead, try to find tunes that relax and fade into the background.
