Four new backhoe-loaders with ‘oomph’ for North America from Case

Four new backhoe-loaders with ‘oomph’
for North America from Case

As one of the pioneers of backhoe-loader technology, whenever Case Construction Equipment introduces new models they never fail to surprise. The latest introduction raises some interesting observations and shows the company’s determination to remain a leader and further broaden the appeal of these versatile work tools.

Realising that there is only so much more you can do to the general overall design of backhoe-loaders, they went back to the drawing board to see how design and new technology could be better integrated to enable much higher productivity. The company remains determined to deliver the best-in-class backhoe and loader for breakout force and lift capacity. It will be interesting to see competitor reaction as Case Construction Equipment has raised the bar to new levels with its new N series centre pivot backhoe loaders which it has just introduced to the North American market. This represents a complete update of its backhoe-loader product line

In a statement the company describes the N Series as “Stronger Everywhere” unveiling dramatic increases in backhoe breakout force and lift, along with increased loader breakout force, lift and reach.

The four models - Case 580N, 580 Super N, 580 Super N Wide Track and 590 Super N - replace the former series. The models are powered by a modern 4.5 litre turbocharged engine: a Case 445T/M3 rated at 59 kW (79 hp) for the 580N and Case 445TA/E3 delivering up to 80 kW (108 hp) for the other models.

Building on heritage

Rob Marringa, Marketing Manager for Case said at the introduction “The N Series was engineered from the ground up. We’ve taken the flagship product of the Case line-up and delivered best-in-class performance from back to front. The new N Series really is ‘stronger everywhere.’ The N Series extends a legacy of loader/backhoe leadership that began when Case introduced the industry’s first factory-integrated loader/backhoe in 1957.”

     “One new feature that is a real game-changer is Case-exclusive Power Lift. This channels the hydraulic power directly to the boom with the touch of a button. As a result, our backhoe lifting capabilities outperform competitive models by as much as 39% – while running at low engine RPM.”

To manage the additional lifting capability, Case engineers have redesigned the boom for greater strength. The new fabricated boom design increases strength while maintaining the over-centre design. Backhoe bucket pins are larger and stronger to accommodate the higher lift capacities. However, the boom retains maintainability with triple bushings and floating pins from the former series booms.

With the higher lifting capacity, the new backhoe-loaders have a working parameter similar to that of a 5 t excavator and the dig depth of a 7.5 t excavator - but the roading ability means no trailer necessary to get the ‘excavator’ to site.

Case did not leave everything to the design engineers. They enlisted the experience of equipment operators from across North America to test and provide feed back on the enhancements. Dennis Zentner from DRZ Contracting, in Delta, British Columbia was one such customer. His comment: “The 580SN WT backhoe performed well on grading, trenching, backfilling, heavy lifting, hole-patching and rock-breaking. Its heavy-lifting ability is fantastic. It will save me from using an excavator for lifting.”

To increase lifting capacity demands more power, which also means an increase in breakout and improved working envelope. The new loader arms are stronger and longer, providing greater loader reach meaning operators can dump material into the centre of a truck for faster loading and increased payloads.
