Key Features & Design Highlights
These are what make the DPU90r Lec770 stand out in its class:
-
Remote Control Operation: Two joysticks for steering (travel direction & rotation), allowing precise curves and control without needing to walk behind the machine. Extremely useful in trenches or tight constraints.
-
Safety via Infrared Receiver Eye / Proximity Sensor: If line‐of‐sight is broken (operator moves out of view), machine stops—important for safety.
-
Compatec System for Compaction Control & Machine Protection: 8-LED display, warns, reduces RPM or even shuts down if overload is detected (e.g. driving on very hard surface). Helps avoid engine overstrain and mechanical wear.
-
Low Overall Height & Compact Transport: Designed so hood and dimensions are manageable for transport; protective, lockable hoods; fold-down lifting eye; compact frame for clearance under shoring/struts.
-
Robust Engine & Cooling: Liquid‐cooled Kohler engine gives more consistent performance under heat or heavy load vs air‐cooled systems. Large tank, large air filter, easy maintenance access.
Benefits / Why It’s Valuable
Here are why many contractors / site managers choose the DPU90r Lec770:
-
High compaction force for challenging soil / rock base — with 20,233 lb-force, it can handle tough compaction layers with fewer passes.
-
Remote control increases safety and operator comfort — especially useful when navigating trenches / braced shoring systems where being behind the unit is hazardous or impractical.
-
Reduced downtime & maintenance — thanks to engine protection systems, easy access panels, large filters, and robust fluid systems.
-
Steering & maneuverability — the reversible and remote-steer capabilities allow tight turns, less repositioning, better efficiency.
-
Strong service life & resale value — built by Wacker Neuson with heavy steel frame, durable base plate, strong brand support.
Applications & Ideal Use Cases
Where the DPU90r Lec770 delivers best results:
-
Trench compaction & sheeting/bracing work where remote operation and steep grade / confined space demands are high.
-
Road base, sidewalk, infrastructure base preparation.
-
Dense fill or mixed granular soils needing high compaction force.
-
Urban job sites with height restrictions, transport constraints, or operators needing remote control.
-
Projects demanding safety features (infrared receiver, automatic cut-offs) and minimal manual labor behind the plate.
Comparisons vs Other Plates / Alternatives
| Comparison | DPU90r Lec770 Strengths | When Another Model Might be Preferred |
|---|---|---|
| DPU90 Lec770 (non-remote) | Same power, but remote adds safety and flexibility; reversible + control ease | If budget is tight and remote isn’t essential; fewer maintenance parts (remote electronics) |
| DPU90r Lem770 | Similar wide plate but possible differences in remote tech or overall height / frame design | If needing slightly different ergonomics or engine version |
| Lighter reversible plates (e.g. ~70-80 kN) | Much more power, fewer passes, more efficient for heavy work | If job is lighter, transport weight or cost constraints matter |
| Bigger plates (e.g. DPU110r) | Wider working width => bigger coverage | But heavier, more fuel, more transport complexity; may overkill for smaller jobs |
Operational Notes & Performance

Maintenance Tips
To ensure the DPU90r Lec770 performs well & lasts:
-
Keep the remote control battery charged and check its operation regularly.
-
Clean and inspect the infrared receiver eye to ensure safety cut-offs operate correctly.
-
Regularly change exciter oil, hydraulic fluid, engine oil & filters per manufacturer schedule. Using correct oil grades (e.g. 75W-90 for exciter) helps.
-
Monitor cooling system (radiator / coolant) closely, especially under hot weather or heavy use.
-
Inspect base plate thickness & condition; damaged or worn plates reduce compaction efficacy and may produce uneven compaction.
-
Maintain recommended fuel quality and regular upkeep of engine (air filters, pre-heating if needed, etc.).
-
Grease / service all pivot points, tie-downs, lifting eyes; ensure frame hoods and access remain tight / sealed.
