Fast installation review
Send the site details that decide the installation method
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.
What to send first
Target diameter or available turning area
Vehicle model, wheelbase, gross weight and ground clearance
Pitless CTB or pit-mounted CTA preference, if already known
Floor or pit condition, voltage, finish and control preference
Destination country, delivery city or port, site photos and drawing
Project review
Site details Huanyu reviews before quotation
Huanyu confirms the final design after reviewing the site, vehicle data, destination country and installation preference.
CTA catalog references support early pit and concrete planning; approved project drawings govern construction
Pit center, depth, conduit, drainage and finished-floor level are checked before installation
Voltage, frequency, phase, cabinet position and cable route are confirmed for the project
Outdoor and basement projects need a drainage plan that avoids standing water
CTB pitless projects still need floor flatness, ramp and vehicle clearance review
Applicable installation steps follow the approved model drawing and manual, not a generic web diagram
Site photos, vehicle data, approach direction, destination and support scope are confirmed before production
Short answer
A car turntable installation starts with the site, not the product code
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.
Pit drawings before concrete
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.
Pitless is not zero planning
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.
Export support scope
Overseas buyers need drawings, manuals, photos, videos and remote guidance, while local civil, electrical and safety checks remain the responsibility of the site team.
Installation quote input checklist
Send these details before asking Huanyu to confirm the model, drawing and installation support scope.

Evidence-backed project handoff
Separate factory support from local site responsibility
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.
What Huanyu confirms for the project
The applicable model, approved project drawing, equipment and packing scope, installation documents and remote technical-support scope. Project documents take priority over catalog references.
What the local contractor verifies
Foundation or slab, pit, drainage, conduit, lifting access and local safety requirements. Mechanical work needs trained installers; electrical work needs a qualified electrician.
Why packing belongs in the review
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.
Drawing-based installation notes
Foundation, conduit, drainage and clearance should be confirmed before production
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.
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.
Pit edge protection rings help reduce concrete edge damage when vehicles drive on and off the turntable.
CTA pit-mounted visual references
Pit, conduit, edge protection and finished-floor details
Use these visuals as planning references when discussing pit-mounted CTA preparation with a local builder or installer.
Site preparation
Use drawings and site measurements to confirm the circle, vehicle approach and cabinet side.
Foundation pit
The pit depth, circularity and finished floor level need to match the confirmed model drawing.
Conduit and drainage
Plan electrical conduit and water outlet routes before the pit is closed by finish work.
Edge protection
A protected pit edge helps reduce concrete damage when vehicles enter and leave the platform.
Turntable positioning
Frame and drive components are positioned before the final top surface is completed.
Finished flush floor
The visible platform should align with the surrounding floor and keep service access in mind.
Control cabinet
Voltage, cable route, cabinet position and control preference should be confirmed before production.
Base structure
A cutaway reference helps explain the recessed structure, support frame and service space.
Installation factor
CTA pit-mounted preparation
CTB pitless preparation
Project stage
Best during design, new construction or major renovation before the final floor finish is closed.
Best for finished garages, operating showrooms and sites where deep excavation is not practical.
Civil work
Prepare pit diameter, pit depth, concrete strength, circularity, edge protection and final level.
Confirm floor strength, flatness, ramp footprint, access clearance and anchoring method.
Water control
Outdoor or basement pits should include a drainage route so water does not stay under the platform.
Outdoor floors still need water flow planning around the ramp, deck edge and electrical route.
Electrical planning
Confirm conduit path, cabinet side, voltage, cable length and emergency stop access before concrete.
Confirm power source, cable protection, control cabinet position and whether the cable crosses traffic areas.
Finished appearance
Cleaner flush-floor result when the pit, platform height and surrounding finish are coordinated.
Platform and ramp remain visible, which is acceptable for many garages, studios and showrooms.
CTB pitless installation checklist
Use this when the garage, showroom, photo studio or driveway floor already exists and the buyer wants to reduce deep construction.
Check existing concrete strength, levelness and surface condition.
Confirm whether the 120 mm low-profile platform and ramp fit the daily vehicle path.
Review low-clearance cars by wheelbase, front overhang and ground clearance.
Plan where power cable, cabinet and remote-control receiver will be protected.
For outdoor use, review rainwater flow, anti-slip finish and electrical protection.
Send photos or a short video of the finished floor before production confirmation.
CTA pit-mounted installation checklist
Use this when the project is still in drawing, new construction or renovation and the owner wants a cleaner flush-floor result.
Confirm pit diameter, depth, circularity and finished floor level from the project drawing.
Use suitable concrete strength and thickness, with floor flatness controlled before installation.
Embed PVC conduit near the planned electrical cabinet side before concrete is closed.
Plan drainage for outdoor, semi-outdoor, basement or wet-area projects.
Protect the pit edge so concrete is not damaged when vehicles drive on and off.
Keep the pit clean and accessible before the turntable modules arrive on site.
Pin-gear installation manual reference
Reference sequence for an applicable pin-gear pit-mounted system
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.
1. Verify the approved drawing and delivered parts
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.
2. Position the central base, rollers and beams
The central base, roller assemblies and connecting beams are positioned from the project drawing before the drive and circular frame are closed.
3. Install the drive and pin-gear ring
The applicable pin-gear manual sequences the motor reducer, pin-gear ring segments and meshing adjustment before the final closure segment is fixed.
4. Assemble the sector frame and electrical system
Sector frames and electrical connections follow the marked project sequence. The approved drawing and manual take priority over any public summary.
5. Run a controlled test before deck installation
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.
6. Install panels and record the handover
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
Lock drawings, voltage, drainage and finish before manufacturing
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.
Site readiness checks
These checks are based on the installation manual workflow and help reduce rework before final fixing and testing.
The local team has the confirmed project drawing and knows which model and diameter is being installed.
The pit or finished floor is clean, accessible and ready before the modules are moved into place.
A level, lifting tools, hand tools, shims, fasteners and electrical tools are available on site.
The control cabinet position, input power and cable route are clear before wiring begins.
The installer can test rotation direction, abnormal noise, remote control and stop function before final fixing.
Unclear steps are paused and checked with Huanyu or the responsible technical person before operation continues.
Installation FAQ
Can a local contractor install the car turntable?
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.
Should the pit be built before the turntable is delivered?
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.
Is a pitless CTB turntable easier to install?
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.
What causes installation delays?
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.
