Wheel loaders Tier 4 Final loader offers many improved features The Volvo L250H wheel loader is a highproduction machine designed to deliver improved productivity and profitability in applications including quarry mining and heavy infrastructure Operators will experience short cycle times high breakout force and improved controllability with this heavy duty machine The L250H will load a 25 ton triaxle onhighway truck in two passes two full buckets for one full truck Featuring advanced technology the L250Hs Volvo Tier 4 Final engine provides high performance and low fuel consumption During the fully automated regeneration process particulate matter collected in the diesel particulate filter is burned without interrupting performance or productivity the company says Fuel efficiency is enhanced with Volvos OptiShift technology which combines the companys Reverse By Braking RBB technology and a torque The eco pedal applies a mechanical push back force when the throttle is used excessively converter with lock up to eliminate power losses and reduce fuel consumption by up to 18 percent Automatic Power Shift APS and Fully Automatic Power Shift FAPS further ensure minimal fuel consumption and fast cycle times shifting the machine gears in line with engine and travel speed for optimal operation Meanwhile Volvos unique eco pedal encourages the operator to ease off the throttle therefore 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 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 Working in hard materials Volvos Z bar linkage provides high breakout force for digging in hard materials and facilitates quick load cycles for increased productivity even in demanding applications The optional Boom Suspension System BSS further boosts productivity by up to 20 percent according to Volvo 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 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 The cab provides a clean and spacious work environment with low internal noise levels vibration protection ergonomically placed controls and ample storage space Fuel and oil levels as well as warning messages are displayed on an easy to read information panel that is clearly visible from the operators seat even in bright sunlight When working in the dark safety and visibility 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 For added safety an optional fire suppression system consisting of up to 16 nozzles is automatically activated inside the engine compartment if excessive heat is detected The system purpose built for Volvo wheel loaders can also be manually activated from inside and outside the cab When carrying out regular service checks the cab can be tilted through 35 or 70 degrees via a hydraulic pump to provide wide access to the vital components www volvoce com 20 PIT QUARRY April 2014 www pitandquarry com
