‘Earth-friendly' heavy-duty lift

The Envirolift uses a vehicle's weight to recharge with each lowering cycle, greatly extending battery life. Under a 72,000-lb. load, for example, batteries complete 50 full cycles as opposed to the standard eight to 10. Panolin, the lift's biodegradable synthetic oil, lasts up to six years before requiring full replacement. Virtually all — 98% — of the materials used to build the unit are recyclable.

Prevents batteries from going dead

Available in 85A and 200A versions, Smart Battery isolators 48525 and 48530 prevent loads on the auxiliary battery from draining the starting battery, so equipment in the field always fires up. Able to work regardless of alternator type, the isolator allows bi-directional charging from the alternator or from other power chargers or converters. Cole Hersee Co. www.colehersee.com.

Medium-duty diesel-electric hybrids

T270 Class 6 and T370 Class 7 trucks automatically select the ideal power mode — electric-only, combined diesel and electric, or diesel-only — and update the driver through a dashboard display. Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. (For more information on how these engines work, see “Heavy hitters” on page 33 of our December 2007 issue.) Kenworth Truck Co. www.kenworth.com.
