The entrance to Volvo Construction Equipment's ConExpo-Con/Agg exhibit (F3432), through what the company has dubbed “excavator alley,” will lead to the manufacturer's largest excavator offered in North America: the 100-ton (90-tonne) EC950F crawler excavator. The reason Volvo CE is emphasizing its excavator lineup is simple, according to Ray Gallant, VP of sales support: more than half of the units sold in construction equipment are excavators.

JCB worked with design and engineering specialists to build a spectacular speed record-breaker that topped 150 mph.

For farmers in a hurry, JCB's Fastrac series agricultural tractors are capable of speeds up to 43 mph (69 km/h) in stock form. But the British company believes in challenging its engineers to improve the breed, and in doing so they've taken the concept of a high-speed ag tractor to new heights.

Off-highway industrial machines require multi-function implement operation with dynamic duty cycles. In many cases, machine implements demand short bursts of full engine power and brake dynamic loads requiring 50% or more of energy consumed. Many next-generation machines reduce energy loss and improve productivity by incorporating hybrid-electric approaches with energy storage. An efficient implement solution enabling the hybrid-electric approach is essential to achieve maximum improvement potential.
