Backhoe Loader Case
RB420F Road Drainage Application Scenario
An illustrative selection scenario for trenching, spoil loading and drainage preparation with the RB420F.
Scenario Summary
- Model
- RB420F Backhoe Loader
- Project type
- Road drainage and culvert preparation
- Application
- Road construction
Operating Requirement
This illustrative scenario starts with a contractor who needs one machine for drainage trenching, spoil loading, aggregate movement and culvert-area preparation along changing work fronts.
The selection must be based on documented digging depth, loader capacity, travel dimensions and written configuration—not on an assumed customer result.
Model Selection Rationale
The RB420F is the model to review when the requirement aligns with a 1.5 m³ loader bucket, 2,800 kg rated load and 4,100 mm standard maximum digging depth. A telescopic arm is optional and must be written into the quotation if the deeper 5,000 mm figure is required.
Selected machine
RB420F Backhoe Loader
A 4WD backhoe loader with a 1.5 m³ loader bucket, 2,800 kg rated load and 4,100 mm standard maximum digging depth.
Pre-Order Verification
- Confirm the exact model, standard equipment and every selected option in the quotation.
- Check the final specification against the dated product-truth record before order approval.
- Agree the inspection evidence, manuals, parts scope and shipping documents in writing.
- Keep every unresolved performance, compliance or commercial claim marked for confirmation.
Intended Use
The intended workflow is to open roadside drains with the backhoe, reposition the machine between short sections, load excavated material and support aggregate handling during culvert preparation.
Why This Configuration Fits
The configuration combines loading and excavation functions in one 4WD machine. Final suitability still depends on trench geometry, ground conditions, access, attachments and the buyer-approved specification sheet.
