Core Features & What Makes It Stand Out
-
Reversible Operation: You can change travel direction (forward/backward) by moving the guide handle, making compaction around corners, near walls, or in tight spaces much easier.
-
Compatec™ Compaction Control: The machine includes a compaction control system with LED indicators. Alerts or RPM reduction/shutdown can occur when the plate is driven on very hard sub-surface to prevent overload.
-
Machine Protection Sensor: Detects overload when driving on too hard surfaces and protects the engine and mechanical components.
-
Center Pole Adjustability & Quick Lowering: The center pole (guide bar) height is tool-free adjustable; it can be lowered quickly for passage under obstacles and raised back to previous operating height.
-
Water-Cooled Diesel Engine: The Kohler KDW702 uses liquid cooling to maintain performance under heat, reducing wear and improving lifespan.
-
Robust Construction: Thick base plate, heavy frame, large fuel & hydraulic tanks. Built for high durability and long service life.
-
Operator Comfort Features: Low hand-arm vibration (HAV ~2.5 m/s²), reasonably low overall height to permit use under struts or tight jobsite constraints. Large air filter, easy panel access.
Benefits of the DPU90 Lec770
Here are the prime advantages:
-
High Compaction Force: 90 kN is powerful enough for large and deep fill compaction, road bases, and mixed or granular soils.
-
Efficiency on Large Areas: With a working width of ~770 mm and forward travel speed ~30 m/min, this plate covers large areas quicker.
-
Versatility in Tight Spaces: Center pole lowering and reversible travel help in restricted environments.
-
Engine Reliability & Cooling: Diesel water-cooled engine ensures consistent performance even in hot ambient conditions.
-
Long Service Intervals: Features like oversized filters, accessible maintenance points, and rugged build help reduce downtime.
-
Safety & Control: Compatec and overload sensors protect both the machine and operator.
Applications: Where the DPU90 Lec770 Excels
-
Road construction and base compaction for asphalt or pavement.
-
Large scale foundation preparation for buildings or infrastructure.
-
Compaction of backfill for utility trenches or pipe bedding.
-
Compacting mixed or granular soils (gravel, crushed stone, sand).
-
Jobs where reversible direction and high capacity are essential (e.g. tight parking lots, areas with obstacles).
Comparisons: DPU90 Lec770 vs Other Plates
| Model | Centrifugal Force | Working Width | Use Case Comparison |
|---|---|---|---|
| DPU90 Lec770 | 90 kN | 770 mm | Heavy reversible plate ideal for large base compaction, professional jobsites |
| Smaller Reversible Plates (e.g. ~70-80 kN) | Less force, narrower width | Better for smaller jobs, tighter budget, lighter soils | |
| Single-direction Plates | Similar force, but no backward movement | Less flexible, slower maneuvering around obstacles | |
| Remote controlled or “r” variants | Same specs, adds remote control convenience | Higher cost, needs safe handling; good for very hazardous or tough access areas |
Important Performance / Operation Details
-
Travel Speed: Forward travel at approx. 30.3 m/min (≈1.6 ft/s) helps cover ground efficiently.
-
Gradeability: Up to ~34% slope, which allows working on inclines where needed.
-
Sound / Vibration Levels: HAV ~2.5 m/s² permits full-shift use; sound pressure LpA approx 94 dB(A) (standard measured) which is high but typical for this class.
Maintenance & Best Practices
To get the most out of your DPU90 Lec770, follow these recommended upkeep steps:
-
Keep air filter clean; large filters help extend intervals, but in dirty environments inspect often.
-
Regular oil and coolant checks; water-cooled systems need proper fluid levels.
-
Check and maintain base plate edges and thickness to prevent excessive wear.
-
Inspect compaction control (Compatec/overload sensors) since they protect machine health; ensure sensor functions are tested.
-
Grease or check hydraulic/hydraulic fluid (if applicable) – large reversible plates have hydraulic components.
-
Ensure proper fuel quality for the diesel engine; water or contaminants reduce performance and increase wear.
-
Check guide poles, handles, center pole lock, and lights regularly for mechanical integrity.
-
Proper transport tie-downs using the lifting eye; secure machine to prevent damage during moving.
FAQs
Q: What types of soils can it compact effectively?
A: Granular, mixed soils (gravel, crushed stone, sand) are ideal. It’s powerful enough for base layers under asphalt or pavement. Fine clay may require moisture control.
Q: Is it usable in high ambient temperatures outdoors?
A: Yes — water-cooled engine + sensible cooling systems are designed for up to ~50 °C (122 °F) ambient.
Q: How does reversible travel work?
A: The travel direction is changed via handle motion (forward/backward) rather than manual lever. This simplifies operator control.
Q: What is the height & clearance?
A: Protective frame height ~60.7 in (~1.54 m), cover frame height ~822 mm (~32.4 in); ground clearance ~830 mm to certain parts.
Q: What fuel and oil capacities?
A: Fuel tank ~7.20 L (≈1.9 US gal); oil filling, hydraulics, exciter oil etc. capacities are specified in manufacturer data sheets.
Summary
The Wacker Neuson DPU90 Lec770 Reversible Vibratory Plate is a top-tier compaction machine for demanding jobs.
