EquipmentWorld.com | November 2016 69 I s the new Genie hybrid articulating boom aerial lift more like a Tesla or Prius? Both, actually. Similar to a Prius, the new Genie Z-60/37FE has a small engine coupled to a generator and battery pack and can run off either or both. But where the Prius offers only fuel economy, the Genie offers fuel effi ciency and high performance – hence the Tesla comparison. The Z-60/37 FE gets its fossil-fueled kick from a 24-horse- power, Kubota D1105 diesel engine – a powerplant that's half the size of the typical engine for this class of aerial lift. But when it comes to performance the Z-60/37FE can give you a full day of work in the in the all-electric mode, or a full week of work on a single tank of diesel in the hybrid mode. The system couples the output of the engine to a gener- ator and brushless AC motor that will direct power to the drive and lift functions, or to charge the batteries, or both. Smart control systems combine the diesel power with en- ergy from the batteries for boosted drive and traction. Independent 4WD Each wheel has an independent drive motor mounted on an oscillating axle. Since the motors run on AC current, they can be fully sealed and even submerged in water without affecting performance, says Adam Hailey, prod- uct manager, Terex Aerial Work Platforms, the division of Terex responsible for the Genie brand. The 30-volt, AC drive motors create 3,600 pound-feet of torque each. In the purely electric mode they consume up to 300 amps each, but switch to the hybrid mode and you get an ad- ditional 200 amps to boost gradability and performance. product report | by Tom Jackson | TJackson@randallreilly.com Genie's diesel-electric boom offers hybrid effi ciency – and robust performance Hybrid technology lets you do the same work with an engine only half the size.
