Pit-mounted CTA Turntable
A CTA pit-mounted car turntable sits inside a prepared pit to create a flush-floor finish. It is best planned during a new build or major renovation because pit depth, concrete, drainage, conduit and cabinet position must match the confirmed model and project drawing.

Send pit and drawing details before choosing a pit-mounted CTA turntable
A pit-mounted car turntable can create a clean flush-floor result, but the pit, concrete, drainage and conduit route must match the selected model. Send drawings and site photos early so Huanyu can check CTA feasibility before production.
What to send first
Pit diameter, pit depth, center point and surrounding finished floor level
Vehicle model, wheelbase, gross weight and expected daily use
Drainage point, conduit route, cabinet side and local voltage
Project stage: drawing, new-build, renovation or existing pit
Destination country, site photos, CAD file or hand sketch for review

CTA pit-mounted system
Pit-mounted planning for flush-floor turntable projects
Pit-mounted turntables are suited to new-build villas, basement garages and permanent installations where a flush floor finish is preferred.
The CTA catalog planning reference uses a 250 mm finished pit depth; the approved project drawing governs the site work.
The catalog pit-diameter reference is the platform diameter plus 30-40 mm, with circularity checked against the approved drawing.
A 200 mm concrete base with C30 or higher concrete is a catalog planning reference, not a substitute for local structural design.
Check pit level, circularity and foundation tolerances against the approved drawing before permanent fixing.
The catalog planning reference includes a 50 mm conduit; the final route and size follow the approved electrical drawing and local electrician.
Outdoor, semi-outdoor and basement installations need a drainage route that keeps standing water away from mechanical and electrical parts.
Installation flow visuals
From site marking to finished vehicle access
These planning reference visuals help buyers, architects and contractors understand the pit-mounted CTA workflow before quotation.
2. Pit and conduit
Prepare the recessed pit, conduit path and drainage direction according to the confirmed layout.
3. Frame positioning
Position the circular frame, drive components and leveling points before final surface work.
4. Flush platform
Check the finished floor level, edge clearance and anti-slip platform surface after installation.
5. Vehicle check
Review vehicle position, turning clearance and daily access after the platform is finished.

Project-specific pit-mounted residential and commercial applications
Best fit
Choose CTA when the project can plan the pit early
A pit-mounted car turntable is strongest when the owner, architect or contractor can coordinate civil work before the final floor finish.
New-build villas, basement garages and architect-led residential projects where the pit can be coordinated early.
Permanent driveway projects where the owner wants a cleaner flush-floor result.
Showrooms or display areas where the platform should integrate with the floor finish.
Projects where civil drawings, conduit, drainage and local installation responsibility can be confirmed before finishing.
Not ideal for
Finished floors where opening a pit would be too disruptive or expensive.
Outdoor or basement sites where standing water cannot be controlled.
Projects without trained mechanical installers, a qualified electrician or a local team able to prepare the site.
Temporary or leased spaces where future relocation may be required.
Planning item
Typical CTA requirement
Confirm before quote
Equipment and pit depth
The CTA catalog uses 250 mm as an equipment-height planning reference.
Use the approved project drawing to confirm finished pit depth, floor level, edge detail and service clearance.
Pit diameter
The catalog civil reference allows 30-40 mm beyond platform diameter.
Confirm the selected model, approved drawing, pit circularity and contractor tolerance before concrete work.
Foundation and edge
A 200 mm C30+ concrete base is a catalog planning reference.
Local structural review, reinforcement, pit edge protection and the approved civil drawing govern construction.
Power and conduit
The catalog reference includes a 50 mm conduit near the cabinet side.
Confirm voltage, frequency, phase, cable route, cabinet position and local electrician requirements.
Water control
Outdoor, semi-outdoor and basement pits need a planned water outlet.
Confirm exposure, drainage capacity, waterproofing and how standing water is kept away from mechanical and electrical parts.
Project responsibility
A flush-floor result starts with a complete handoff
Catalog values support early planning. The approved project drawing, quotation and installation documents govern production and site work.
Buyer or project team sends
Vehicle data, approach dimensions, site stage, pit or floor drawing, local power, destination and clear photos of the planned installation area.

Pit-mounted car turntable FAQ
When should a pit-mounted car turntable be planned?
Plan it before final concrete and floor finishing. Pit depth, pit diameter, conduit, drainage and cabinet position are much easier to coordinate before the building work is locked.
Does CTA always require drainage?
Indoor dry projects may have different requirements, but outdoor, semi-outdoor and basement projects should review water flow carefully. Standing water in the pit can create installation and maintenance problems.
Can a local contractor install the pit-mounted turntable?
The work should be handled by trained mechanical installers and a qualified electrician using the approved project drawing and applicable manual. Huanyu can provide project documents and remote guidance, while local civil, electrical and safety compliance remain with the site team.
