Interview with Designers of the Ultra-Large Excavators
The cutting-edge technologies for downtime and maintenance cost reduction, developed on the world-class EX8000 Ultra-Large Excavator, are adopted to the New EX-6 Series Giant Models.
EX5500
More Than Durable - Just Plain Tough
Built-in toughness means the Hitachi will continue to get giant-sized jobs done fast.
Rigid Box Design - Resists bending and twisting forces.
Computer-assisted analysis was used to check that the frame box can withstand heavy-duty excavation work.
Solid Cast Track Frame - More strength for this key area.
The track frame is cast as a solid unit and includes a flange for improved reliability. This non-welded design is used exclusively on large Hitachi models.
Strategically Positioned Oil Coolers - Helps keep oil temperatures
Two oil coolers are used for optimal cooling efficiency. They are positioned far from the engine radiator for even better cooling potential.
High-Mounted Compact Travel Motors and Optional Travel Motor Guard - Help to boost durability at rugged work sites.
This design helps protect the travel motors from damage by rocks.
Rugged Track Links - Shoes include roller guides for extended service life.
This design has proven itself on Hitachi's popular Giant EX Series. The roller guides have been added to help extend service life.
Constant Correct Track Tension - Nitrogen gas accumulators absorb abnormal track tension.
Helps prevent abnormal track tension from causing damage. Travel is automatically stopped if accumulator pressure exceeds a preset level.
