LBX Company LLC, makers of Link-Belt excavators, scrapmasters and logmaster recently announced the addition of the 8000 Quantum hydraulic excavator in a standard and mass version 1.34-cubic-meters to 4.59-cubic-meters (1.75 cu. yd. to 6 cu. yd.) bucket rating. This 80,000-kilogram (176,400 lb.) standard excavator and 80,300-kilogram 177,000 lb) mass excavator model is newest addition to the Quantum Series. The Link-Belt 8000 Quantum made its North American debut during ConExpo. Since the end of April the prototype machine has been on demonstration in the Northern Kentucky area. This all-new 8000 Quantum features a long undercarriage, a Nephron oil filtration system, an illuminated LCD service monitor, and the same operators control station found on all Quantum models, which provides control, accessibility and operator comfort. The 8000 also features the Quantum-style rounded sheetmetal design and red/granite gray color scheme. Easy Maintenance System (EMS) The 8000 Quantum features the Easy Maintenance System (EMS). EMS incorporates a new technologically advanced bushing pin and seal design that lengthens the greasing interval for all attachment pins. The industry standard calls for greasing intervals of every 50 hours. Where EMS greasing intervals are extended to 1,000 hours or six months, whichever comes first. Intelligent Quantum (IQ) Control Intelligent Quantum (IQ) control is a computer-aided, hydraulic control system designed to ensure maximum efficiency at any job-site, no matter the condition. IQ control features four selectable working modes: heavy, standard, light and fine. The excavator can be set to accommodate any task, from heavy production digging to fine precise lifting control. The working mode system, combined with heavy lift and boom priority mode, balances engine speed and pump output for increased productivity, efficiency and fuel savings. A push-button cushioned attachment control can be selected for the boom and arm hydraulic circuits, which incorporate a cushion valve to reduce vibratory shock. Quantum excavators also feature free swing control, allowing the operator to disengage the swing brake, which provides precise control and added safety when swinging a load. The excavator can be set in an attachment work mode, which matches the engine’s rpm to the hydraulic requirements. By doing this, the operator matches the oil flow to the needs of specific allied attachments. With an auto warm-up system, the 8000 will warm itself up automatically, depending upon the engine coolant temperature at start-up. This system will operate for about 15 minutes with engine speed increasing gradually until normal operating conditions are reached. Additional features include three-speed travel (high, mid-range or low) single pedal travel, automatic downshift, auto idling, and a one-touch decelerator. Nephron Oil Filtration System Link-Belt’s exclusive Nephron Oil Filtration system was designed for longer component life while being environmentally friendly. By eliminating contaminants of one micron or more in size, the Nephron system significantly reduces hydraulic system breakdowns, repair costs and downtime. The main advantage with the Nephron system is that hydraulic fluid in the 8000 Quantum excavator needs only be changed every 5,000 hours, as opposed to every 2,000 hours for other excavators, resulting in a significant cost savings. In addition, cleaner oil results in longer life for hydraulic components. Most important in terms of the environment — less frequent oil changes reduces waste contaminants impacting our environment. Superior Cab Design The 8000 Quantum operator’s control station provides the operator with comfort and control. A reclining, sliding, fully-suspended seat and control consoles can be adjusted to fit the operator, providing all-day comfort. A full-view front window and large rear and side windows provide excellent visibility in all directions. LEXAN MARGARD is used in the rear and side view windows, which eliminates the need for vandalism covers. Both control consoles have illuminated soft-touch membrane switches, which are dirt and moisture resistant. A liquid crystal display monitor displays up to 19 messages, programmable in 14 different languages which keep the operator in touch with critical machine functions. The selected travel speed! swing lock on/off, working mode and time is continuously displayed on the monitor. Also displayed are the fuel level, hydraulic oil temperature, and coolant temperature. Because the cab is mounted to the frame on six fluid-filled mountings, the operator experiences minimal vibration from the excavator’s strenuous activity. Other features include a heater with a three-speed fan, an oscillating ventilation fan, air conditioning, an AM/FM radio, a pop-up skylight window, an intermittent windshield wiper and washer and three safety control lockouts including a gate lock safety shut-off. Increased Accessibility and Serviceability Servicing the 8000 Quantum is simplified by the use of standard equipment, which includes large wide opening doors, and catwalks located on both sides. An on-board self-diagnostic system helps the service technician troubleshoot before turning any wrenches. Standard quick disconnects for pressure checking and central lube banks for attachment pins also provide quick routine maintenance. A grease gun and tool kit are provided as standard service equipment. A swing-out oil cooler assembly comes standard. This cooler design provides an extra wide opening access for routine servicing and thorough cleaning. A removable dust protection screen situated in front of the radiator protects its core from large particles of dust. For more information, call 606/543-0303 ext. 444.
