Compact Equipment Cabs Evolve to Boost Operator Comfort and Productivity

Designs provide more room and control at the operator’s fingertips.

Mercedes-Benz Trucks announced at bauma 2019 it is bringing semi-automated driving in all speed ranges into series production.

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.

Collaboration stretches R&D resources

Danfoss' Application Development Center addresses industry demand on OEM research and development departments.

Wheel loaders designed for operators

Current designs strive to optimize the operator environment

Cummins' aftertreatment device combines the Cummins Compact Catalyst with Selective Catalytic Reduction (CCC-SCR).

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.
