Building on M-Series models, the new Next Generation Cat 906, 907 and 908 wheel loaders boast a reengineered operator’s station, leveraging exclusive technologies to improve operator experience and provide larger wheel loader model comfort on a smaller platform. The loaders’ new Cat C2.8 engine, plus upgraded drive and powertrain, deliver faster roading speeds and drive train performance than the predecessor series. The 906, 907 and 908 models have respective operating weights and bucket sizes of 5,730 lbs. and 0.95 yd.; 5,792 lbs. and 1.05 yd.; and, 6,632 lbs. and 1.15 yd.
The new sealed and pressurized cab improves the operator experience, while keeping previous design functional aspects like raised floor pedals and two doors to make cab cleaning easier. Optimum visibility is achieved with larger standard side mirrors, optional parabolic lens electric and heated mirrors, plus front and rear camera options. Seat mounted controls improve the loaders’ operating ergonomics.
A multifunction joystick controls travel direction and speed, proportional auxiliary flow, differential lock, and constant hydraulic flow without operators removing their hand from the joystick. Like larger Cat wheel loaders, compact-model operators will be able to choose from a range of seats, including a new premium heated and ventilated model.
A first for this class size, new in-cab-programmable kickouts with high-definition rotary sensors mounted to the loader arms better protect operators from unwanted shock and vibration due to buckets striking the ground and/or hitting dump stops at max height. Proper kickout operation also saves up to 20 percent of bucket cutting edge life. Rather than leaving the cab for setting, the operator remains inside the cab while setting upper, lower and attachment kickout positions at the touch of a button. Cylinder snubbing is also enabled to provide the operator with added protection.
The heart of the new cab design is the Next Generation control monitor, which offers a range of real-time machine operating information. It allows the operator to configure hydrostatic transmission response, auto engine idle shutdown and a utility powertrain mode that provides operators with a more intuitive means of controlling ground and engine speed—ideal when working with hydromechanical attachments.
In dusty environments, the new reversing-fan option assists in keeping cooling cores clean for more efficient temperature control. Through an in-cab soft-touch button, the system can be turned off, set to operate in an automatic mode or momentarily activated by the operator. Automatic mode uses the factory-setting to reverse direction for 10 seconds every 10 minutes. Frequency and duration of automatic reversing can be changed easily by the operator via the new control monitor.
To meet demand for increased multifunctionality with lift and tilt while powering hydromechanical tools, the Next Generation wheel loaders feature a new standard pressure compensated valve, allowing operators to simultaneously control implements and operate hydromechanical attachments seamlessly. Increased working auxiliary pressures make work easier and improve steering to reduce operator fatigue.
Efficient, high-illumination LED lights options are now available for both working/roading and under-hood-service lights to better illuminate work areas in low-light conditions. Task-focused LED under-hood lighting simplifies servicing in poor ambient light. A unique resistor bank built into the body of Cat LED roading lights keep the lamp assembly warm enough to melt snow and ice, improving efficiency over conventional LED roading lights when operating in colder climates. — Caterpillar Inc., www.cat.com/requestCatinfo
