Selection overview
Use the reference to frame a project review
Raise a reviewed roll-forming workflow toward the installation elevation.
Use handover geometry to frame the ARC-C21 decision
ARC-C21 is retained to examine handover geometry where work-zone transitions matter more than a single headline height. Its 21m label is an archived reference class, not evidence of a supplied envelope or operating result. ARCLIFT works as a technical selection and supply partner and uses the reference only to structure the buyer’s evidence review.
Plot the forming location, roof-edge transfer point, and each receiving zone on the same plan. The decision is whether one reviewed crawler route can be assessed across those transitions or whether separate handling arrangements need comparison.
Map the variables zone by zone
The configuration may change with the access route, ground bearing basis, support geometry, work elevation at each handover, panel run-out, and weather and rescue controls. Outreach, roof slope, edge distance, travel orientation, and obstruction clearance belong on the drawing; the archived class does not answer them.
Send the review team:
- Access route survey with turns, gradients, gates, and setup areas
- Ground bearing basis and the proposed support geometry at each position
- Work elevation and horizontal handover distance for every marked zone
- Panel run-out direction, receiving path, and roof-edge obstructions
- Weather and rescue controls, exclusion areas, and local approval documents
Cases that need a different comparison
This reference may not fit if panel transfer crosses an uncontrolled edge, support positions conflict with buried services, travel between zones is unavailable, or rescue access cannot follow the planned sequence. It also cannot confirm a forming-line interface without the issued project inputs.
Close the decision with project records
The signed technical schedule and approved drawings control the final configuration. An approved load chart, interface schedule, and packing data must be issued for the reviewed arrangement before procurement or lift planning. Ask ARCLIFT to review the zone map and interface list as an integrated equipment supplier, without treating archive content as approval.

Project inputs
Prepare these inputs before configuration review
The checklist follows the Crawler lifts family route.
- Work zones and roof geometry
- Panel profile and forming-line data
- Access route and support conditions
Workflows to assess
Review the interfaces around the equipment
These are review topics, not claims that the reference is suitable for a site.
Forming-line interface and material path
Weather and rescue planning
Questions and documents
Close the review with available reference documents
What project data is needed before configuration review?
Does ARC-C21 currently guarantee a 21m working height?
No. 21m is an archived source reference class, not a current-model guarantee. The required work height, outreach and configuration must be checked against the project geometry and confirmed in the signed technical schedule and approved drawings.
What must be supplied before a configuration review?
Send roof plans and sections, required work zones, panel profile and material, coil and forming-line data, ground or support information, access constraints, destination power and local documentation requirements.
Which documents control the final order?
The signed technical schedule, approved general-arrangement drawings, approved load chart, interface list and project packing data control the final configuration. Website text and editorial visuals do not.
Documents to request and validate
- Signed technical schedule
- Approved drawings
- Approved load chart
Availability and applicability depend on the reviewed configuration. The signed project documents, not this page, control an order.
