Describe where each load must be placed
A delivery truck with a crane has to carry the material and place it at the destination. Crane mass, the subframe, outriggers and mounting position take up payload and deck space before any cargo is loaded. Select the crane and truck layout together.
The heaviest object is not necessarily the controlling lift. Its pickup and placement positions, radius, height, obstacles, available setup space and ground support can make a lighter delivery more demanding. Put representative cases in the purchase brief rather than specifying only maximum tonnage.
Check the lift and the remaining delivery capacity
For each case, the supplier needs to identify chart coverage and the installed configuration. Then review what the completed truck can still carry. A crane with a larger headline rating may leave less cargo capacity without solving the placement problem.

| Decision | What to establish | Condition or limit |
|---|---|---|
| Load chart | Check load at actual radius and configuration. | Headline crane rating is not capacity at every radius. |
| Boom geometry | Match articulation or telescopic reach to obstacles and placement. | Boom type alone does not guarantee the required envelope. |
| Truck payload | Subtract crane, subframe, body, options, crew and fluids. | A larger crane can reduce cargo payload. |
| Setup | Verify outrigger space, ground support and exclusion zone. | No load chart compensates for an unsafe setup. |
Put representative delivery lifts into the purchase schedule
Build the quotation around a small schedule of real delivery cases. For each case record the object and lifting accessories, pickup position, placement position, obstacles and available setup space. Ask the supplier to identify the applicable chart and installation drawing for each case. Mark unsupported cases as unresolved rather than allowing a headline tonnage to stand in for chart coverage.

| Scenario | Procurement evidence | Decision boundary |
|---|---|---|
| Kerbside material delivery | Pickup and placement radius, clearance and permitted support deployment | A restricted outrigger footprint needs an explicitly permitted chart configuration. |
| Repeated pallet delivery | Loaded truck axle schedule, usable deck area and representative handling cycle | Crane installation mass reduces the truck allowance available for cargo. |
| Placement over an obstacle | Boom path, required height and chart coverage throughout the proposed movement | A reachable endpoint does not prove an acceptable path to that point. |

- Exact installed crane and chart revision
- Completed truck mass and axle calculation
- Deck and stowed transport dimensions
- Attachment and lifting-accessory scope
- Signed list of covered and excluded delivery cases
Agree which delivery cases the offered configuration covers
Keep the load and lifting-accessory masses, pickup and placement positions, obstacles and setup envelope together. Ask for the applicable chart and installation drawing, with unsupported cases left open. Procurement review does not replace a qualified lift plan for the eventual site.
Information to prepare for this review
- Maximum load and dimensions
- Required horizontal radius and vertical reach
- Pickup and placement obstacles
- Lift frequency and duty pattern
- Required remaining deck payload and body length
- Ground condition and available outrigger space
Records to request and keep
- Load and placement schedule
- Manufacturer load chart and configuration notes
- Completed-vehicle mass and axle calculation
- Outrigger, subframe and installation documentation
Common mistakes and what to check instead
- Selecting a crane whose headline rating equals the load: Read capacity at the required radius and setup.
- Ignoring cargo payload after crane installation: Calculate the completed truck and intended deck load.
- Assuming outriggers fit every delivery site: Survey access, deployment space and ground support.
Scope of this guide
This guide is not a lift plan or operating instruction.
Qualified persons must control installation, inspection, setup and lifting.
Stop work when the load chart, setup, ground, outrigger deployment, exclusion zone or load control is uncertain.
Sources and applicability
U.S. construction crane operating requirements and manufacturer procedures. Applicability depends on jurisdiction and activity; not a KEEYAK certification.
Sources checked:
U.S. reference linking permitted outrigger deployment to manufacturer procedures and the load chart. Local rules and exact installation documents remain controlling.
Sources checked:
Controls the project-input, quotation, approval and inspection workflow described in this guide.
Provides public checklists and worksheets; the signed project documents remain controlling.
Defines the relevant product family and published configuration boundaries. Project-specific ratings require the selected OEM documents.
Official U.S. reference supporting configuration-specific load charts, stability factors, inspection identity and removal of hazardous deficiencies. Local rules may differ.
