Volvo CE’s new L250H wheeled loader uses OptiShift to boost performance, safety and fuel economy
Volvo CE unveiled its new L250H wheeled loader at Conexpo 2014
Volvo Construction Equipment’s new Tier 4 Final/Stage IV-compliant L250H wheeled loader has been designed to perform heavy tasks with better performance, safety and fuel economy levels using the manufacturer’s OptiShift technology.
In North America the L250H is ideally suited to working with on-highway trucks, and the L250H will load a 22.7tonne tri-axle on-highway truck in just two passes. That’s two full buckets for one full truck says Volvo.
Volvo CE’s OptiShift technology works by combining the company’s patented Reverse By Braking (RBB) technology and a torque converter with lock-up to eliminate power losses and reduce fuel consumption by up to 18%.
And the use of automatic Power Shift (APS) and Fully Automatic Power Shift (FAPS) technology further ensures minimal fuel consumption and fast cycle times, shifting the machine gears in line with engine and travel speed for optimal operation.
Volvo CE’s innovative eco pedal encourages the operator to ease off the throttle, lowering fuel consumption, by applying a mechanical push-back force when the throttle is used excessively and the engine rpm is about to exceed the economic operating range.
And intelligent load-sensing hydraulics supply power to the hydraulic functions only when required for smooth, fuel-efficient operation, as well as excellent control over the load and attachment.
The L250H’s optional Boom Suspension System (BSS) is said to boost productivity by up to 20% by absorbing shock and reducing the bouncing and bucket spillage that occurs when operating on rough ground. This enables faster and more comfortable work cycles and increases machine life. The model’s optimally-shaped bucket has been designed to incorporate a spill guard, side cutters and wear plate for faster and more efficient bucket fill and longer service life.
With a variety of product options, Volvo CE customers can adapt their machine to access more applications, such as rock and waste handling.
When working in the dark, safety and visibility on the L250H wheeled loader are enhanced by reflectors that follow the contour of the machine. LED entrance lights illuminate the cab for safe entry and exit and additional LED work lamps light up the work area.
The L250H’superior durability and ease of maintenance ensure maximum machine uptime and minimum expenditure on servicing replacement parts. The batteries are maintenance-free as are the rear axle cradles, which are fitted with greased-for-life bushings and bearings.
Machine wear is reduced thanks to an optional, automatic lubrication system that can be adjusted according to application.
When carrying out regular service checks, the L250H’s cab can be tilted through 35° or 70° via a hydraulic pump to provide wide access to the vital components.
