Heavy-duty suspension from Hendrickson

Hendrickson developed the INTRAAX EDT and EDL trailer suspension systems for severe applications. The EDT (top) is top-mounted and the EDL (bottom) is for low-ride-height/liftable configurations.

Hendrickson International (Booth S-9941) claims as an "industry first" its integrated 13,610-kg (30,000-lb) capacity INTRAXX 300 Class suspension axle system for mining and other off-highway applications. Offered in both top-mount and low-ride-height/liftable configurations, the ride height of the 300 Class ranges from 355 to 483 mm (14 to 19 in) for the top mount and 230 to 430 mm (9 to 17 in) for the low-ride-height/liftable.

The most robust of the new system are the extreme-duty AAEDT 30K and AAEDL 30K for severe applications. They feature low-pressure air springs with steel pistons and full bottom plate coverage as well as high-damping, extended-service shock absorbers. Heavy-duty options include rear-mount shock absorbers and chain down-stops. Both suspensions are full 13,610-kg (30,000-lb) structural- and axle-capacity systems. For more mainstream heavy-haul applications, Hendrickson offers the AAT 30K and AAL 30K that provide a 13,610-kg (30,000-lb) suspension capacity matched with a full 11,340-kg (25,000-lb) axle rating.

The INTRAXX 300 Class system can be combined with Under Beam Lift (UBL) for heavy-duty liftable applications. The UBL's compact profile allows for close axle spacing and leaves ample room for auxiliary equipment under the trailer. Liftable axles offer increased flexibility and maneuverability, extend tire life, and allow vehicles to carry more payload.

The Under Beam Lift (UBL) can be used with the INTRAAX suspension for liftable applications. The UBL mechanism has a mass of less than 27 kg (60 lb) and allows for auxiliary equipment under the trailer.

INTRAXX's single busing, in unison with rigid trailing arms and solid axle connection, combine to deliver improved ride, stability, and control. The systems feature patented axle-wrap technology and beam-mounted brake hardware for improved durability and brake performance.

GM Powertrain adds industrial engine

According to GM Powertrain, its small-displacement Vortec 1600 is well suited for residential standby power generation.

The Vortec 1600 from GM Powertrain is a 1.6-L single overhead cam engine adapted for the industrial market from the automotive market. The inline four-cylinder engine widens GM's industrial engine range from 1.6- to 8.1-L.

GM anticipates that residential standby power generators will be a major application area for the engine. Its 1.6-L displacement conserves fuel compared to some larger displacement engines but still provides adequate power for most residential needs. Originally designed by Opel, the engine is assembled at the Sao Jose dos Campos engine plant in Brazil. It is currently used in Chevrolet Corsa sold in South America and the Opel Corsa sold in Southeast Asia.

Features of the Vortec 1600 include a 79 x 81.5 mm (3.1 x 3.2 in) bore and stroke, a 9.4:1 compression ratio, and an iron block with a cast aluminum cylinder head with valve seat inserts. The Vortec 1600 also features a distributorless ignition system, which reduces maintenance and increases reliability.

The Vortec 1600, sold without an intake manifold or fuel system, allows OEMs to customize their own fuel/intake system to sell to their customers. The Vortec 1600 will be adaptable for use with gasoline, liquid propane, or compressed natural gas (CNG). Each fuel type has different applications. Gasoline is good for higher output mobile equipment. Liquid propane versions are preferred for indoor material-handling vehicles. CNG is a favorite of genset manufacturers. An OEM calibrated engine control module is available for each specific need.
