Describe the material movement
Record material information, source and destination, haul distance, grades, road support, passing/turning areas and placement requirements. Obtain the project operating and haul-road requirements before matching equipment. Loose volume and mass need an explicit basis when comparing bodies, bowls and payloads.
Compare complete loading methods
A loader/excavator and truck system differs from an open-bowl or elevating scraper sequence. Include any loading support, road maintenance and placement machine. For the 623, unresolved width/height conflicts remain visible; they cannot be replaced with the 621 dimensions for convenience.
Start at the receiving area
A tipper and an ejector-body truck have different discharge equipment and envelopes. The 730 EJ comparison should include receiving conditions and the manufacturer-approved unloading procedure. An ejector does not remove the need for site-specific stability and operating planning.
Model the cycle and ready-to-work cost
Separate loading, travel, discharge, return and waiting using supported assumptions. Inspect bodies/bowls, discharge mechanisms, articulation, brakes and tires, and price repairs needed for equivalent readiness. Compare the whole fleet and mobilization package without assigning a generic output or cost per moved unit.
Decision worksheet
| Requirement | Evidence to collect | Effect on equipment choice |
|---|---|---|
| Material and distance | Density/basis, route and receiving brief | Choose supported payload and loading method |
| Cycle balance | Loader, haul and discharge assumptions | Avoid queueing hidden by a capacity headline |
| Ready-to-work package | Body/bowl, tires and repair quotes | Compare complete systems and transport needs |
Before you decide
Questions to close out
- Define material quantity and measurement basis.
- Check route and receiving-area requirements.
- Include loading and road/placement support.
- Obtain condition and transport quotes for the complete package.
A supported haulage decision links the loading method, route, receiving area and fleet condition in one transparent scenario.
