What the buyer or site team sends
Vehicle data, approach direction, floor or pit condition, local power, destination, site photos and a marked plan, CAD file or hand sketch.

Civil work and electrical preparation
Plan a car turntable installation for CTA pit-mounted or CTB pitless projects. Check pit or floor preparation, concrete, drainage, conduit, voltage, cabinet position and the details needed for quote review.
Quick Project Review
Name, country, application and one reply channel are enough to start. Vehicle, site and installation details can be added now or in the follow-up.
Quick facts
Key information for early model selection before Huanyu reviews the site, vehicle data and installation conditions.
Fast installation review
Send diameter, vehicle model, floor or pit condition, voltage, destination country and site photos for quote review. This is faster than asking for a generic price because Huanyu can compare CTB pitless and CTA pit-mounted options around the real site.
Architects & contractors
Help a buyer, architect, civil contractor, electrical contractor and equipment supplier agree the site inputs before final drawings and quotation.
This brief is for planning only. The approved project drawing, quotation and local code requirements govern final dimensions, loads, interfaces and installation work.
A useful installation review starts with the largest vehicle and the real site constraints, not with a guessed platform diameter.
Two common planning directions have different civil interfaces. Final selection remains subject to project review.
| Planning direction | Typical site interface | Review first |
|---|---|---|
| CTA / pit-mounted direction | Platform is planned around a prepared pit so the finished surface can align with the surrounding floor. | Pit geometry, structural support, drainage, conduit route and finished-floor tolerance. |
| CTB / surface-mounted direction | Platform is planned above the existing floor when a new pit is impractical or undesirable. | Floor flatness and capacity, access transition, edge treatment, cable route and clear height. |
The local project team should resolve civil conditions before equipment arrives.
Electrical inputs must be confirmed for the actual project and local rules.
Delivery planning is part of installation planning. Confirm access and lifting responsibilities before dispatch.
The following is a planning allocation. The project contract and approved documents must assign final responsibility.
| Workstream | Buyer / project lead | Local architect / civil | Local electrical | Installer / mechanical | Huanyu / supplier |
|---|---|---|---|---|---|
| Vehicle and use brief | Own / approve | Review | Input if needed | Input if needed | Review and advise |
| Site measurement and access | Coordinate | Own / verify | Verify electrical access | Verify install access | Review submitted information |
| Pit, slab, floor and drainage | Approve scope | Design / execute locally | Coordinate conduit | Check readiness | Provide project interface information |
| Power, protection and earthing | Approve scope | Coordinate | Design / execute locally | Coordinate | Provide project electrical requirements |
| Packing, freight and unloading | Coordinate destination | Confirm site access | Not normally owner | Plan lifting / receipt | Provide project packing information |
| Mechanical installation | Provide access | Confirm civil handover | Coordinate power readiness | Execute per agreed scope | Provide project instructions / support per contract |
| Commissioning and handover | Witness / accept | Close civil items | Complete electrical checks | Complete mechanical checks | Support per agreed project scope |

Project review
Huanyu confirms the final design after reviewing the site, vehicle data, destination country and installation preference.
Short answer
For pit-mounted CTA projects, confirm the pit, concrete, drainage, conduit and cabinet position before production. For pitless CTB projects, confirm the finished floor, ramp space, vehicle clearance, power route and drainage before shipment.
Many installation pages mention a pit, but buyers still need to know when the pit drawing, diameter, depth, cabinet side and finished floor level should be confirmed.
Surface-mounted CTB projects avoid a deep foundation pit, but the floor, ramp area, vehicle clearance, cable route and drainage still need to be reviewed.
Overseas buyers need drawings, manuals, photos, videos and remote guidance, while local civil, electrical and safety checks remain the responsibility of the site team.
Send these details before asking Huanyu to confirm the model, drawing and installation support scope.
Evidence-backed project handoff
A useful installation review names what the buyer sends, what Huanyu confirms and what the local team must verify. It also fixes the packing and unloading scope before the machine reaches site.
Vehicle data, approach direction, floor or pit condition, local power, destination, site photos and a marked plan, CAD file or hand sketch.
The applicable model, approved project drawing, equipment and packing scope, installation documents and remote technical-support scope. Project documents take priority over catalog references.
Foundation or slab, pit, drainage, conduit, lifting access and local safety requirements. Mechanical work needs trained installers; electrical work needs a qualified electrician.
Module split, unloading access and included accessories can change freight and on-site work. Confirm the packing and installation scope in the quotation before shipment.

Customer-supplied installation evidence
This privacy-masked photo shows a completed 4.5 m CTA pit-mounted turntable with a 3,000 kg rated load in an Australian automotive showroom. It confirms the installed setting, but it does not replace the project drawing, vehicle data or local site checks.
Use a CAD plan, floor plan or legible hand sketch. Mark the entrance, gate or garage door, nearby walls and columns, proposed turntable center, available clear circle, vehicle approach arrow and key dimensions.
Photograph the narrowest gate or garage opening straight on. Keep both ends of the tape visible and the number readable; include clear width and, when access height matters, clear height.
Take one wide photo from the vehicle approach and one floor or pit photo. Show slope, finished-floor edges, drains, conduit, cabinet side and fixed obstacles without hiding the surrounding route.
Send the vehicle model or a dimension sheet with length, width, wheelbase, gross weight and ground clearance. A screenshot of a reliable manufacturer specification is acceptable when the values are legible.
Customer, business and vehicle-identifying details have been removed for privacy. The vehicle brand shown does not imply endorsement.
Drawing-based installation notes
Reference drawings show how the pit, concrete, PVC conduit, drainage and turntable clearance are planned. The final drawing is confirmed according to the project model and site.
CTA pit-mounted visual references
Use these visuals as planning references when discussing pit-mounted CTA preparation with a local builder or installer.

Use drawings and site measurements to confirm the circle, vehicle approach and cabinet side.

The pit depth, circularity and finished floor level need to match the confirmed model drawing.

Plan electrical conduit and water outlet routes before the pit is closed by finish work.

A protected pit edge helps reduce concrete damage when vehicles enter and leave the platform.

Frame and drive components are positioned before the final top surface is completed.

The visible platform should align with the surrounding floor and keep service access in mind.

Voltage, cable route, cabinet position and control preference should be confirmed before production.

A cutaway reference helps explain the recessed structure, support frame and service space.
Use this when the garage, showroom, photo studio or driveway floor already exists and the buyer wants to reduce deep construction.
Use this when the project is still in drawing, new construction or renovation and the owner wants a cleaner flush-floor result.
Pin-gear installation manual reference
This summary applies to the pin-gear pit-mounted installation manual, not every CTA or CTB model. Friction-drive catalog models use a different structure, and the approved project drawing and manual always govern the work.
Before installation, the trained mechanical team checks the pit center, motor pit, cable outlet, approved civil drawing and delivered parts. A qualified electrician reviews the electrical work.
The central base, roller assemblies and connecting beams are positioned from the project drawing before the drive and circular frame are closed.
The applicable pin-gear manual sequences the motor reducer, pin-gear ring segments and meshing adjustment before the final closure segment is fixed.
Sector frames and electrical connections follow the marked project sequence. The approved drawing and manual take priority over any public summary.
Mechanical movement and electrical operation are checked before the top panels are installed. If circularity, concentricity or local binding is abnormal, work stops for remeasurement and adjustment.
After the controlled test is accepted, the panels can be installed. The handover record should identify the project, equipment, drawing revision, installation lead, test result and open items.
Before production confirmation
Late changes to platform diameter, cabinet side, voltage, drainage route or surface finish can affect drawings, packing and local installation work.
For an overseas car turntable project, the factory can prepare the rotating platform, drawings, manuals and packing plan, but the site still needs local civil and electrical coordination. The most useful early document is not a general brochure. It is a project drawing that matches the selected diameter, vehicle data, pit or floor condition and control cabinet location.
If the site is outdoors, semi-outdoor or in a basement, drainage should be treated as a design item, not an afterthought. If the site is finished, the buyer should confirm whether a ramp, raised platform edge or visible cable route is acceptable before choosing a pitless solution.
These checks are based on the installation manual workflow and help reduce rework before final fixing and testing.
Yes. Huanyu can provide drawings, manuals, photos, videos and remote guidance. The local contractor should still review concrete, drainage, electrical work, lifting equipment and site safety according to local practice.
For CTA pit-mounted projects, the pit should be prepared according to the confirmed drawing before installation. The pit must match the final model, diameter, depth, conduit side, drainage and finished floor level.
It usually reduces deep civil work on a suitable finished floor, but it is not a no-planning product. The floor, ramp, vehicle clearance, power route and drainage still need to be checked before production.
Common delays come from an unfinished pit, wrong pit level, missing drainage, unclear cabinet position, blocked access for heavy modules, or late changes to voltage, finish or platform diameter.
