, of Lexington, Ky., has upgraded the 140-ton HTC-3140 and long boom HTC 3140 LB truck cranes with new features and the latest emissions technology available.
The new 3140s now have Cummins engines in both their upper and lower works. The upper uses the Tier 4i/Stage IIIB QSB 6.7 engine with 215 hp and 685 foot-pounds of torque. The lower uses Cummins’ 2010 EPA emissions-compliant ISX15 with a diesel particulate filter (DPF) and selective catalyst reduction (SCR). It has 581 hp and 1850 foot-pounds of torque.
Mated to the new engine is an Eaton UltraShift Plus transmission with 11 forward speeds, three reverse speeds and no-clutch-pedal shifting. The transmission’s Hill Start Aid prevents roll-back or roll-forward when launching on grades.
Redesigned tilting cabs feature revised gauge and control placement. A rubberized coating keeps the floor resistant to wear and easy to clean. A swing-up roof window with windshield wiper and washer, engine-dependent warm-water cab heating, a sun screen, cup holder, and a five-way-adjustable seat with headrest ensure a comfortable work environment. The lower cab has office racks, a hat rack, and an easy-to-read LCD display.
On the carrier, the 3140s use the same outrigger controls and self-leveling system as the ATC-3275. The outriggers (and winches) comply with the latest OSHA mandates and include a light at each outrigger. Despite their new emissions technology and upgrades, the 3140s gained no additional weight.
