The pour and parking positions need the same site sketch
A site sketch should place the required pours relative to a proposed setup area, with the entrance, route, turns and overhead restrictions shown. Structures and obstructions along the boom path matter as well as the final hose position.
The selected boom's envelope needs the required positions marked using its stated datum and equipment configuration. Vertical reach, horizontal reach and movement over an obstruction answer different questions. Separate maximum figures cannot be combined into one assumed working position.
The KEEYAK concrete pump truck category organizes candidate chassis configurations. These labels do not assign a universal boom length or pump output. Request the actual installed equipment and completed dimensions for each proposal.

| Part of the job | Information to provide | What must be checked |
|---|---|---|
| Getting to the position | Entrances, turns, road limits and overhead restrictions | Finished travel dimensions and route suitability |
| Deploying the equipment | Available setup area and ground information | Support geometry, documented reactions and site assessment |
| Covering the pour | Required positions and boom-path obstructions | Exact boom envelope and permitted working conditions |
| Delivering concrete | Concrete specification and requested duty | Selected pump and pipeline capability under stated conditions |
Assess support space before committing to reach
The chassis rectangle occupies only part of the working installation. A setup drawing needs the full outrigger arrangement, nearby excavations, underground features and deployment restrictions. The ground-support assessors also need the equipment documentation relevant to their review.
SCHWING's outrigger-system descriptions associate different front and rear arrangements with identified machines. They demonstrate why support geometry is model specific. A KEEYAK installation needs its own footprint, reaction information and any documented reduced-deployment capability.
Restricted setup space requires an approved arrangement for the offered equipment and required working area, checked with the responsible site and equipment specialists. A permissible working sector from another model cannot be transferred to this truck. Partially extended supports are not a general option.
Specify concrete duty separately from the boom
Concrete specification, placement duty and the delivery-line arrangement provide the basis for pump selection. Quoted output and pressure need the conditions that support them. The supplier should identify usable duty for the selected package because maximum output and maximum pressure may describe different conditions.
Boom-mounted line, planned additional line, connections and cleaning arrangements need to be identified in the proposal, with compatibility and selection responsibilities assigned. A chassis or boom category leaves those details open. This guide supplies no pumping or cleaning procedure.
Keep travel requirements in the assessment after the equipment is selected. The completed pump installation, carried accessories and operating equipment affect mass, axle loads and transport dimensions. Use the vehicle-limits guide for the finished-vehicle checks.
Compare scope and evidence before the order
A comparable quotation identifies the chassis, pump, boom, support system, controls, pipeline equipment and accessories. Documents, inspections, commissioning and destination responsibilities need to be included or excluded explicitly, with the installed equipment models named.
Dimensional, equipment-identity and functional checks should be recorded against the actual unit. A contractual pumping demonstration also needs agreed material, setup, measurement and acceptance conditions. Unloaded boom movement demonstrates a different function from concrete placement.
Use the quotation-comparison guide to resolve exclusions. Leave an unanswered setup or duty requirement visible rather than converting it into an assumed capability.
Concrete pump truck questions
Should the buyer select the longest available boom?
Choose the envelope that covers the required positions from a viable setup. Additional nominal reach does not resolve restricted access, inadequate support space or an obstructed path. Give every candidate the same site sketch.
Does an 8×4 chassis tell us the pump output?
No. Identify the actual pump and boom package and its documented duty. The axle label helps describe the vehicle configuration, but it does not specify the installed pumping performance.
Can a pump truck operate where outriggers cannot fully extend?
Only a documented arrangement for the exact machine and required working area can establish that possibility, alongside the competent site assessment. State the restriction before selecting equipment. This guide does not approve a reduced-deployment setup.
