PRINOTH and McNeilus Collaborate on Design of Tracked Concrete Mixer

A tracked mixer allows vehicles to quickly and easily move through soft soils or rugged terrain to get to jobsites almost or entirely inaccessible by a standard vehicle.

Operator cabs are becoming more simplified to ease operation and improve visibility.

Comfort and Ease of Use are Key Factors for Compact Equipment Cab Designs

As equipment becomes more complex, multifunctional control and more simplified cab designs are improving comfort and machine operation.

The Western Star 49X features a stronger, lighter chassis that is equipped with the company’s new X-series cab. It enables a total weight savings of over 350 lbs. in like-for-like spec’ing versus the current Western Star 4900.

Western Star Builds Next-Generation Vocational Truck

The 49X was designed from the ground up to meet the most demanding vocational applications.

Connectivity, Electrification and Automation Continue to Drive On-Highway Vehicle Market

Manufacturers are advancing electric and autonomous vehicle designs due to growing market interest and improving vehicle performance.

The 536 hp 944K Hybrid Wheel Loader boasts the biggest cab, quickest boom-raise time, and fastest cycle times in its class.

Advanced Powertrains Generate ROI Despite Low Fuel Prices

The focus for advanced powertrains and hybrid drive systems in today's construction equipment looks beyond fuel economy to increased performance and ease of operation.

The Case D Series excavators use the Case Intelligent Hydraulic System (CIHS), which incorporates Boom Economy Control, Auto Economy Control, Swing Relief Control and Spool Stroke Control.

Hybrids Aren't the Only Earthmovers That Can Cut Fuel Costs

While hybrids get all the hype, advanced drivelines and hydraulic system innovations in traditional earthmovers yield major efficiency gains.

The search for efficiency

Diesel engines gain efficiency through downsizing and downspeeding.

As with the Stage IIIB/Tier 4 Interim Ecomax engine, it will be possible to de-tier the Tier 4 Final range, to allow customers to sell used equipment in less regulated territories. All JCB dealers worldwide will have the technology to remove the SCR kit, reduce the fuel injection pressures and recalibrate the engine control system to de-tier the Ecomax engines. A lubricity doser may be required in some countries depending on the quality of local fuel.

The unwanted aftertreatment

A study by Manfredi & Associates investigates how emissions regulations will change how equipment is purchased and sold.

Paradigm shifts present engineering challenges

In engines of similar or same displacement, the main factors that contribute to an increase in specific power are: utilization of more complex-structure turbochargers, such as variable-geometry or dual-stage; an increase in peak cylinder pressure and the use of an SCR-only aftertreatment system without any recycling of exhaust gas in cylinder, especially in engines with a displacement higher than four liters.

The trend toward higher power densities

Tier regulations have pushed for more advanced engine technology and optimized systems, the rewards of which are more power from smaller engines.

'Nothing takes the place of having all of your design engineers sitting around the table and the engineer who is producing the axle knows exactly what the transmission engineer [is] going to do and the engineer who designs the engine knows what the peak torque needs to be,' says Doug Phillips of Volvo CE.

Design integration steps up the game

Systems integration enables OEMs to provide customized features and capabilities for improved productivity and efficiency.

Most manufacturers have moved to high-pressure common rail fuel injection systems, such as the one visible on this QSF2.8 engine that pumps out 49 to 74 hp.

Investigate final Tier 4 options

The 336E H captures the swing brake energy with a hydraulic accumulator. That energy is then used to accelerate the excavator upper structure back in the opposite direction.

Leave nothing to waste

Hybrid technology captures and reuses energy that is normally wasted.
