Designed as simple, cost-effective heavy-lift truck cranes, the 140-ton (120-mt) HTC-3140 and HTC-3140 LB (Long Boom) deliver unparalleled capacity and transportability as the largest truck cranes in North America. For 2012, they also deliver a host of new features and the latest emissions technology available. These latest upgrades keep the 3140 on the cutting edge without adding unnecessary complexity.
The new 3140’s now have Cummins engines in both the upper and lower. The upper uses the Tier 4i/Stage IIIB QSB 6.7 engine with 215 horsepower (160 kW) and 685 foot-pounds (929 Nm) 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 horsepower (434 kW) and 1850 foot-pounds (2 508 Nm) of torque. Not only do these engines meet the latest emissions requirements, they provide the power to move effortlessly on the job or on the road.
Mated to the new engine is an Eaton UltraShift PLUS transmission with 11 forward speeds, 3 reverse speeds and no-clutch-pedal shifting. The transmission’s Hill Start Aid prevents roll-back or roll-forward when launching on grades, simplifying operations for even the most inexperienced drivers. The crane also has a two-speed auxiliary transmission for precise jobsite travel. On the road, the 3140 can top 65 mph (104.6 kph).
Further updating the HTC-3140/3140 LB is the in-house designed Link-Belt Pulse total crane operating system. Link-Belt Pulse monitors multiple crane functions including real-time latching boom operation, counterweight removal and installation, and has extensive diagnostic capabilities. Link-Belt Pulse also functions as a rated capacity limiter with indicators for maximum allowable load, load on hook, overload, crane geometry, wind speed, and two block conditions.
Also new to the 3140 are redesigned cabs with new gauges and revised control placement. The upper cab tilts up to 20 degrees keeping the operator comfortable at high boom angles. Gauge and control placement has been overhauled and includes a new outrigger operation with self-leveling. A durable, 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 is user friendly with office racks, a hat rack, and an easy-to-read LCD display.
On the carrier, the 3140’s 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.
Just as important as what these cranes have is what they don’t have. The 3140’s gained no weight despite adding new emissions technology and many other features. The HTC-3140/3140 LB is still the strongest, most versatile truck crane on the market.
