Lewis and Clark on a heavy haul

Can you imagine a haul that requires four years of planning? That’s the time heavy haulers with Oregon-based Emmert International put into planning and executing a move earlier this year of two massive barrel-shaped coke drums.

Severe Untitled 1Kenworth T800s, spec’d for super-heavy haul with 550-hp engines and 18-speed transmissions backed by a 4-speed auxiliary, hauled the drums for ConocoPhillips. After traveling from Lewiston, Idaho, 700 miles east to the company’s oil refinery in Billings, Mont., the drums will be used in a $50 million upgrade of the refinery due to be completed next fall.

Yellow Untitled 1“The coke drum moves presented us with one of the most challenging routes ever faced by a heavy transport company,” said Terry Emmert, company founder.

Remarkable is the custom design work Emmert put into the two trailers, dubbed Lewis and Clark (pictured), 226-foot-long 32-axle 128-wheel trailers distributing top and bottom sections of each shipment evenly. The nicknames stemmed from the loads following part of the exploratory trail of Meriwether Lewis and William Clark. Emmert used one T800 to pull and another to push each load, grossing 702,200 pounds, with a third T800 serving as a spare power unit.

The first shipment left in February to encounter an arctic blast of winter weather, which delayed its arrival until April. The second was in turn delayed en route by high runoff from the Yellowstone River that flooded the U.S. 12 bridge crossing. It finally made Billings Aug. 4, marking the end of the historic haul.

Aftermarket parts provider Alliance Truck Parts has added an EZ-Assist clutch designed for work truck applications that require severe torque transfer for heavy loads. Rated at 2,050 lb.-ft. of torque, the new model in the EZ-Assist line targets the most demanding applications, including gravel and heavy construction hauling, logging and mining.

Allison introduced a 10-speed fully automatic twin-countershaft range-type truck transmission called the TC-10. Allison Untitled 1Like other Allisons, the transmission will have a torque converter with lockup clutch in place of a standard dry clutch at front. But it will have helical gears integrated with a twin-countershaft layout for the five forward speeds and the reverse gears in the main box, as well as a two-speed planetary range box at the rear. Production will begin Oct. 1, 2012.

In addition to availability enhancements, Eaton expanded its UltraShift Plus line of automated transmissions with the Vocational Active Shifting (VAS) and Vocational High Performance (VHP) models. The 10-speed VAS platform is available between 1,050 and 1,650 lb.-ft. as well as multitorque, and the 13-speed VHP platform is available in models between 1,650 and 2,050 lb-ft. Lower torque options are available in the Vocational Construction Series (VCS) and Vocational Multipurpose Series (VMS) transmissions. The 18-speed Multipurpose Extreme Performance platform, to handle torque up to 2,250 lb.-ft., also has been approved for applications outside linehaul and heavy haul, including logging, mining, oil field, construction, city delivery, refuse and off-road.

Grand Junction, Colo., recently accepted delivery of four natural gas-powered Mack TerraPro Low Entry refuse trucks. Grand Junction operates an all-Mack fleet of 12 refuse trucks, including gas models.

Navistar’s International MaxxForce engines rank highest in customer satisfaction in J.D. Power’s 2011 U.S. Heavy-Duty Truck Engine and Transmission Study and perform particularly well in four factors: engine reliability and dependability, engine warranty, vibration at idle and average fuel economy.

Navistar also introduced private-label International brake drums built to SAE and ASTM standards. Results include 2 to 4 pounds in weight savings per drum and improved heat dissipation.


Tough Tires Untitled 1Tough tires

Continental released two new construction tires, the HSC1 (pictured) and the HDC1. The HSC1, a heavy construction steer tire, is designed with a wider tread and shoulder rib and a tread pattern that prevents stone retention. The HDC1 is a drive tire for construction featuring a 32/32-inch tread depth and self-cleaning pattern. Both tires are available in sizes 11R22.5 and 11R24.5 for load range H.
