Terex-Hanomag High Lift Loaders: Legacy, Reliability, and Practical Insights
#1
Understanding the Terex-Hanomag Lineage
The Terex-Hanomag high lift loader represents a unique intersection of German engineering and American branding. Hanomag, a historic German manufacturer known for its robust construction equipment, was acquired by Komatsu in the 1980s. During the transitional period, some Hanomag machines were marketed under the Terex name, particularly in North America. These hybrid-branded machines—like the high lift loader in question—are often considered rare, yet mechanically solid.
Terminology Clarification
- High Lift Loader: A wheel loader equipped with extended lift arms or linkage geometry to achieve greater dump height, ideal for loading high-sided trucks or hoppers.
- Hanomag: A German manufacturer of construction and agricultural machinery, later absorbed by Komatsu.
- Terex: A global manufacturer of lifting and material handling equipment, which at one point distributed Hanomag machines under its own brand.
- TD25C: A model designation often associated with dozers, but in this context may refer to a specific loader variant.
Mechanical Reliability and Parts Availability
While the Terex-Hanomag high lift loaders are praised for their mechanical robustness, parts availability can be a challenge due to their hybrid branding and limited production run. Owners often report the following:
  • The drivetrain and hydraulic components are durable, with minimal failure rates under normal operating conditions.
  • Electrical systems may require retrofitting or rewiring due to aging harnesses and obsolete connectors.
  • Filters, seals, and wear parts can often be sourced through Komatsu channels, given Hanomag’s integration into Komatsu’s supply chain.
  • Some structural components, such as lift arms or linkage pins, may require custom fabrication if damaged.
Recommended Maintenance Parameters
To ensure continued reliability, operators should adhere to the following service intervals and checks:
  • Engine oil change: Every 250 hours
  • Hydraulic fluid inspection: Every 100 hours; full change every 1,000 hours
  • Transmission fluid: Every 500 hours
  • Greasing of lift arms and pivot points: Daily or every 10 hours of operation
  • Tire pressure and tread inspection: Weekly
  • Electrical system check: Monthly, especially grounding and fuse integrity
Case Story: A Loader That Outlived Its Fleet
In rural Indiana, a contractor reported using a Terex-Hanomag high lift loader for over 15 years in a gravel pit operation. Despite the rest of the fleet being replaced twice, the Hanomag loader remained in service with only minor hydraulic repairs and a starter motor replacement. The operator noted, “It’s not the prettiest machine, but it’s the one that never lets us down.”
This anecdote reflects a broader sentiment among owners of legacy equipment: reliability often trumps modern features, especially in demanding environments.
Operational Advantages of High Lift Geometry
The high lift configuration offers several practical benefits:
  • Increased dump height allows direct loading into tall-sided trucks without ramps or intermediate conveyors.
  • Improved reach reduces the need for repositioning, enhancing cycle times.
  • Ideal for agricultural silage loading, waste transfer stations, and aggregate handling.
However, the extended linkage also introduces higher stress on pivot points and hydraulic cylinders, necessitating more frequent inspections and greasing.
Modern Alternatives and Retrofit Suggestions
For operators seeking similar functionality with modern support, consider the following:
  • Komatsu WA320 High Lift: Offers similar geometry with full parts support and telematics integration.
  • Volvo L70H High Lift: Known for smooth hydraulics and operator comfort.
  • Retrofit kits: Some companies offer high lift conversion kits for standard loaders, though structural integrity must be verified before installation.
Solutions for Parts Sourcing
If OEM parts are unavailable, consider these alternatives:
  • Cross-reference part numbers with Komatsu equivalents
  • Use aftermarket suppliers specializing in legacy equipment (e.g., FP Diesel, H&R Construction Parts)
  • Partner with local machine shops for custom fabrication of pins, bushings, and brackets
  • Join regional equipment owner networks to exchange surplus parts or technical manuals
Conclusion: A Machine Worth Preserving
The Terex-Hanomag high lift loader may be a “rare bird,” but its legacy of reliability and practical design makes it a valuable asset for operators who prioritize durability over digital dashboards. With proper maintenance, creative sourcing, and a bit of mechanical ingenuity, these machines can continue serving for decades—often outlasting newer, more complex counterparts.
In the world of heavy equipment, sometimes the best lift comes from the past.
