Volvo is positioning its L110H and L120H wheel loaders as the company’s most environmentally-friendly and fuel-efficient machines to date. The company’s latest generation of machines for the 18-22 ton class are powered by an 8-liter Tier 4 Final/Stage IV-certified engine with fully automatic regeneration designed to combine high performance with low emissions and low fuel consumption.
The fuel efficient Volvo D8J engine is paired with a Volvo powertrain and intelligent hydraulics, which only supply power on demand. The load-sensing hydraulics are designed to ensure fast response for outstanding control over the load, as well as shorter cycle times. The Reverse-By-Braking (RBB) function automatically reduces the engine rpm and applies the service brakes when the operator changes the direction of the machine. This not only conserves fuel but also reduces stress on the drivetrain, thereby extending component life. Meanwhile, Volvo OptiShift technology combines the RBB function with a lock-up torque converter to create a direct drive between the engine and transmission, eliminating power losses in the torque convertor and reducing fuel consumption by up to 18 percent. The eco pedal further reduces fuel consumption, thanks to mechanical push-back force, which encourages the operator to ease off the throttle when the engine rpm is about to exceed the optimum operating range.
The L110H and L120H are designed for a wide range of applications, from material handling and rehandling and road construction to utility work. A choice of Volvo attachments - including a variety of buckets, material handling arms, forks, sweepers and snow blades - contributes to that versatility. The attachments are designed as an integral part of the wheel loader, with functions and properties matched to minimize energy losses and increase productivity. Meanwhile, the Volvo unique Torque Parallel (TP) linkage is designed to deliver high breakout torque and excellent parallel movement throughout the entire lifting range. The optional Boom Suspension System (BSS) reduces bucket spillage, boosting productivity by as much as 20 percent on rough ground according to the OEM.
H-Series wheel loaders are designed to provide a safe, clean and comfortable operator environment, whatever the conditions outside. The operator enters the ROPS/FOPS-certified cab via a three-point access ladder with anti-slip steps supported by sturdy and ideally-positioned handrails. The wide doorframe opens at a 95-degree angle and can even be opened remotely as an option. A cab entrance light is also available as an option for increased safety when entering and exiting the machine.
Inside, the cab is designed to be spacious, with plenty of storage for personal belongings. Sound insulation helps keep internal noise levels to a minimum, while improved seat and vibration protection ensure a smooth and comfortable ride. Air quality is managed by an industry-leading filter that allows 90 percent of the cab air to be recirculated for continuous dust removal.
To limit operator fatigue, all the controls and information panels have been ergonomically positioned. For ease of operation, the optional multi-function joystick gives the operator simultaneous and precise control of the hydraulic functions. Forward, reverse and kick-down functions are also included on the right hand arm rest. The machine’s vital information – such as fuel and oil levels – is displayed on an easy-to-read screen that is clearly visible from the operator seat, even in bright sunlight. Basic configurations and tests can be performed without the operator having to move from the seat.
Daily service checks on the machine can be carried out using grouped service points. The engine hood opens electronically so the operator or technician can easily gain full access to the engine compartment. Other components are designed so that they require minimal maintenance. The rear axle cradles contain maintenance-free lubricated-for-life bushings and bearings. The cooling fan can be reversed for self-cleaning of the cooling units.
