Durability and Reliability
- Our engineers have decades of experience and a track-record for excellence
- We take a conservative approach and go beyond the standards - such as using pins and bushings that are 15% larger than the SAE standard and then we thread them to prevent flex typically caused by side loading
- All structural components, including the boom and stick are made from high grade structural steel
- 4 independent wheel drives provide true all-wheel-drive and eliminates exposed components under the machine
- Our engine is designed to handle up to 425 horsepower but we are calling for 275
- The engine cooling system is oversized by 18%
- The hydraulic system is designed to run 25% cooler than typical machines
- We developed systems that are more efficient, which uses less power, which places less stress and wear on components, which leads to longer durability
- We perform extensive Finite Element Analysis (FEA testing) and strain gauge testing on all major structural components
- We use Bosch Rexroth for our main pumps and swing pump
- Cooling fans are driven by Vane pumps which are longer lasting and more fuel efficient than gear pumps
- Built-in engine air pre-cleaner is followed by a 2-stage filter system
- The hydraulic fluid runs through a 2-micron kidney-loop filter at 10gpm
Machine Operator's point of view
Machine performance
- Proprietary Bosch Rexroth controller helps to create a very smooth, fast and efficient system
- Electro-hydraulic controls are adjustable for safety preferences and operator preferences
- Joystick steering eliminates the need for a steering wheel – better visibility
Cab - an extremely comfortable and quiet workplace
- Ground access for safety
- Taller, wider, deeper than the typical cab
- Tube construction with double walled, insulated, hand laid fiberglass shell
- Viscous mounting at all 4 corners – the best technology for sound and vibration isolation
- Auto HVAC controller
- High capacity AC unit is in a separate but integrated compartment under the cab
- Cyclone and secondary air filters in a pressurized cabin
- 30% less exhaust noise through use of an exhaust silencer
- Xenon lighting is mounted below cab to reduce glare and provide exceptional night-vision
- AM/FM/CD/MP3/XM ready audio system
- A place for a lunch cooler, thermos, drink, cell phone/2-way radio, and operator's manual
- Two 12V DC power outlets - one keyed the other continuous power
- Fully adjustable lumbar support, headrest, seat back
- Air cushion height adjustment/suspension
- Excellent lateral/lumbar/thigh support
- Glass is tempered for safety and tinted for comfort
- All glass in the cab is safety glass
Maintenance and repairs – Faster, less frequent, more help
- Wires aren't just color coded – every wire is labeled for its specific use
- Most daily maintenance activities are done under one panel with protection from the sun and rain
- Large top cover provides unmatched accessibility
- Lincoln auto-lube system
- Maintenance notification through IQAN is based on predetermined maintenance intervals or feedback from filter monitors
- Engine compartment lighting is under the side panel and the top panel maintenance areas
- Hose burst protection on bore side of main and secondary boom cylinders
- Parker valves, fittings and ancillary pumps with "standard" lined sizes
- Parker and Donaldson filters make it easy to find common maintenance parts
- Main hydraulic reservoir connection points have shutoff valves to reduce waste and mess
- Engine oil drain is a hose with a valve that can come through the upper structure for easy no mess changes
- Accessories are added easily thanks to extra relays, switches and wiring in all 3 electrical boxes
IQAN system - An extensive monitoring & diagnostic system that's also easy to use
- Links to Exodus so your machine can be monitored instantly – no cost and no waiting for travel time (requires T-Mobile service – 1st year is included)
- Sends text messages to the yard manager's cell phone or a dealer as well as alerting the machine operator via the monitor in the cab when maintenance is due or if there is a problem with the machine.
- Programmed by Exodus engineers specifically for our machines so we can better support our customers
- Never see a code – our system describes specifically what's wrong instead of giving a code
- Error codes and pressure spikes are stored in the system
- Cycle count (grapple or magnet cycle) is logged in the system
Maintenance costs and fuel costs
- Tier III John Deere engines have best in class fuel economy
- Regenerative hydraulics feeds power back into the system during boom down functions
- Variable/reversible engine and hydraulic cooling fans work independently and only operate at the level necessary for each system – conserving up to 30hp
