Lithium batteries, in general, are normally used for a wide variety of applications and are known to last longer than their competitors in addition to producing twice the voltage as well. When it comes to aircraft engines that are started electrically, one can go in for a lithium ion starting unit that will not only last longer but will provide a superior start as opposed to lead-acid batteries that have been in the market for sometime now.

One of these devices is specifically known as the Lithium twin pack, which is a 28 VDC pack, and comes with dual, redundant chargers with a total of 7 amps output and requiring a recharge time of approximately four hours.
There’s no doubt that these starting units are the very latest that the market has to offer when it comes to portability and in being long-lasting as well especially for turbine engines that are used for very light or light turbine engines.

As mentioned earlier, its portability is a big advantage as it is 42 % lighter and 32 % smaller in comparison to lead-acid batteries but yet is able to provide the same power as well. Finally, as with other batteries, sulfation problems do not exist with this type of battery.

However, what one must keep in mind is that the battery should not run down to 23 volts.

Titanium alloys consist of a combination of titanium and other chemical elements, such as aluminum or tin. Such metallic alloys are lightweight, corrosion resistant, and possess high strength-to-weight ratios.  Due to these qualities, titanium alloys have been used in a variety of applications, including power generation equipment, marine hardware, and chemical processing.

While there are several types of titanium alloys, the most commonly used alloy is the titanium 6Al-4V alpha-beta alloy. It is a two-phase, a + b structure with aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Titanium 6Al-4V applications include: compressor blades, discs, and rings for jet engines; rocket engine cases; and helicopter rotor hubs. The metals engineering company, Richard Metals, used Ti-6AI-4V-Eli (extra low interstitial) to create the escape mechanism for NASA’s Ares Orion rocket. It is also the grade of alloy most commonly used for thick-walled highly-stressed parts, such as the Japanese “Shinkai” for taper stress joints. These alloys are available in plate, sheet, bar, or forged billet form.

As one of the simpler processes in the world of manufacturing, roll forming is an ideal method for producing parts that are long in length or that will be made in large quantities. Roll forming lines begin with metal strips housed on a large spool.  These strips generally measure between 1" and 20" in width and 0.0004 and 0.125" in thickness.  This strip is unrolled from the spool (which is held on a dispenser) and fed into the special metal fabrication machinery that has been designed specifically for this process.  The metal strip, after passing through the cutoff attachment, is sent through the forming rolls, from which the process gains its name.  Generally, shaped rolls have been arranged in a sequence in order to create the intended shape over a series of stages.  Some common roll layouts include overhung spindle rolls, flower-shaped, side rolls, and progressive upper/lower rolls.  The arrangement depends on the desired final shape.

I specifically requested a truck with a lift gate and an electric stacker on the phone yesterday and the guy on the line says , “Yeah, he’ll be there.” Of course, I take his word for it.

Rookie mistake.

Of course, the driver shows up bright and early the next day  at 7 a.m., and, of course, he shows up without any material handling equipment.  I’ve been there since 6 making sure all the tags are hung and the purchase orders are squared away and the declaration documents are annotated. This is absolutely the last thing I need. The Canada job is next week, and it was a mission to gather all our supplies and pack them up for cross-border shipment.  The customs and NAFTA paperwork was more complicated than I thought they’d be and I’d had to stay late to make sure the prep job on the barrels had gone according to plan. They’d arrived naked, with no finish, and we’d had to stain them to match the color palate that had been chosen in the design. I’d stayed late to palletize the signage and the balsa wood animal heads and the jars and here I was early the next morning and dealing with this.

Without the benefit of an electric pallet jack or even a hand pallet jack, we somehow had to manage the thousand pound laden pallets, six in total, onto the back of his truck.  Of course, the lift gate was inoperable.  Jose said he’d had an accident just yesterday There had been a row of manlifts and work platforms he’d been trying to avoid in the yard he’d pulled into. It looked like he’d backed into the loading dock and busted the latching equipment and probably some hydraulic lines and the controls as well.

Of course Julie was hysterical demanding I call the company back and get Vineet on the line and how dare he-? Frankly, I didn’t have the time or inclination to listen to her tantrums. We needed the pallets on those trucks and in the next shipment or they’d never be ready for the casino job. It was set to start bright and early Monday morning and this gear had to be in country fast.

We had one of those combination dolly/platform trucks, but the tire was busted flat on it and the thing was just about useless. I talk it over with the driver.

He climbs in and pulls out just about the sorriest looking hydraulic lift table and a dented dolly that had definitely seen better days.
It wouldn’t be much of a lift table.  And the work platform on the truck was narrow and cramped.

This was gonna be rough.
