Speed limiter proposal: 6 slides on the basics

The DOT has packed a lot of information in its 118-page proposal to require speed limiting devices heavy-duty vehicles. Here we highlight some of the basics: the cost-benefit analyses on the three suggested speed settings, the requirements for new trucks, the possibility of requiring older trucks to be retrofit, and the proposed penalties for non-compliance.

Drivers Are Key To Maintenance Success

The first line of defense for well maintained trucks are your drivers. They are required to do pre- and post-trip inspections and submit DVIRs, but the way those inspections are completed varies widely.

There are things you can do to make sure that all inspections are done in a thorough, consistent manner. If you are still using paper forms for pre- and post-trip inspections, you are unwittingly part of the problem.

Volvo’s Iron Knight Truck Sets New Speed Record



Volvo is again using high-profile stunts and viral video to highlight its engineering skills, and the latest is The Iron Knight, the world's fastest truck, breaking the record set by a previous special Volvo truck.

The record-breaker, which has the DNA of Volvo's FH on steroids, is custom-built in every respect – except for a modified Volvo D13 engine and the series-manufactured I-Shift Dual Clutch transmission. The engine has 2,400 hp and the truck can accelerate from zero to 100 km/h in 4.6 seconds.

Nigel Atterbury, Volvo Trucks Senior Designer, explains in the video, “We've pretty much taken a standard gearbox and packaged it into this fantastic beast behind us.”

On a closed-off airfield in Falifors, Sweden, the Iron Knight set two FIA world land speed records. Its two one-kilometer runs averaged 21.290 seconds or 169.083 km/hour (or about 105 mph), and the half-kilometer average was 13.710 seconds and 131.291 km/hour (about 82 mph).

The truck was piloted by Boije Ovebrink, who has more than 30 years' experience of both car and truck racing. He has previously beaten five speed records and in 1994 was European Truck Racing Champion.

“Volvo Trucks' The Iron Knight can be summarized in one single word: perfection,” said Ovebrink. “It's beautiful to look at and is an unparalleled powerhouse when you floor the accelerator. This is the third record-breaking truck I've driven, and I can't think of a better follow-up to Wild Viking and Mean Green,” says Ovebrink.

The last time we reported on Ovebrink, back in 2012, he was driving Mean Green, said to be the world's fastest hybrid truck. Nigel Atterbury, Volvo Trucks Senior Designer, explains that compared to Mean Green, the Iron Knight is 1,000 kilos lighter and puts out 600 horsepower more.

Of course, the point was to demonstrate the I-Shift Dual Clutch, which allowed the ...Read the rest of this story

Dual Shield Protects Power Sources on Trucks

Purkeys has developed the Dual Shield designed to simplify adding additional electrical devices to heavy-duty vehicles and protect the source that powers them.

The Dual Shield provides a single source with multiple protected ports for electrical devices. It gives the vehicle two levels of protection to help counteract parasitic loads from electrical systems like a low voltage disconnect and a timed disconnect.

Other Purkeys products, such as the DC to AC 1500 Watt Power Inverter, have LVDs that protect the vehicle from parasitic loads by shutting off the device when a set voltage is reached. This keeps batteries from becoming too discharged to start the vehicle. In addition to the LVD, the Dual Shield has a timed disconnect that will shut off running devices within an hour after the ignition is turned off.

The Dual Shield has LEDs that can show drivers when there is power running through the system or when devices have been shut off.

This electrical accessory simplifies adding necessary electrical devices to heavy-duty vehicles by providing a centralized, protected location for technicians to connect these supplementary devices. The Dual Shield safety features can stop vehicle batteries from becoming severely discharged, thus keeping them in better condition.
