Patent CN111762253B
Updated November 4, 2026Motorized Garden Landscape Flowerpot Transport Cart
Moving heavy potted plants by hand strains workers and slows down landscaping projects. Traditional carts require individual lifting of each pot. This motorized solution uses a synchronized gear-and-incline mechanism to lift and shift an entire batch of pots in one motion, reducing physical labor and increasing efficiency for nurseries and landscape teams.

Splat! What let you down?
⚙️
Gear-Rack Drive
A motor turns a gear that moves racks, translating rotation into linear lift.
📐
Incline-Leverage Lift
Rollers on swing arms ride inclined plates to raise the carrying frame automatically.
🪴
Multi-Pot Handling
The carrying frame is sized to lift several pots at once, reducing trips.
🛑
Blocking Security
Spring-loaded swinging blocks prevent pots from sliding off during movement.

The problem
In commercial gardening and landscape maintenance, moving large numbers of potted plants is physically demanding and time-consuming. Workers typically bend down, lift each pot individually, and place it onto a standard flatbed cart. This repetitive lifting causes fatigue and increases the risk of back injury. Furthermore, loading pots one by one slows down project timelines, especially when transferring stock between greenhouses, trucks, and installation sites. Existing automated solutions are often too complex, expensive, or require precise alignment of each pot, making them impractical for rugged outdoor environments where dirt and debris are common.
The solution
This patent describes a motorized cart that automates the lifting and shifting of pots. Instead of manual handling, the operator positions the cart near a group of pots and activates a single switch.
- A drive motor rotates a first gear.
- This gear meshes with two racks mounted on sliding plates along the sides of the collection box.
- As the racks move backward, they pull guide sleeves and support rods.
- Attached to these rods are swing bars with rollers that rest against inclined plates.
- The backward motion forces the rollers up the incline, causing the swing bars to pivot upward.
- This pivoting action raises guide rods, which lift the carrying frame holding the pots.
- The frame then moves horizontally toward the fixed placement plate, depositing the pots securely.

Who it is for
- Commercial Nurseries: Staff who need to move trays of pots from greenhouse benches to delivery trucks quickly without repeated bending.
- Landscape Contractors: Teams installing plant beds who want to reduce labor hours spent on transporting materials across large sites.
- Municipal Parks Departments: Crews maintaining public gardens who require durable equipment for daily pot relocation tasks.
- Event Planners: Companies setting up floral displays who need to move large quantities of decorative pots efficiently between storage and venues.
How it works
The main parts

| No. | Part | What it does |
|---|---|---|
| 1 | Collection Box | The base structure housing the mechanism. |
| 101 | Placement Plate | Fixed surface where pots are deposited. |
| 103 | Drive Motor | Provides power to rotate the first gear. |
| 104 | First Gear | Converts motor rotation to rack movement. |
| 402 | Racks | Linear gears that move backward when driven. |
| 403 | Guide Sleeves | Hold support rods and move with the racks. |
| 405 | Swing Bars | Pivot arms that lift via roller interaction. |
| 407 | Rollers | Travel along the inclined plates to create lift. |
| 5 | Inclined Plates | Static ramps that force the swing bars upward. |
| 409 | Carrying Frame | Holds the pots; lifted by the guide rods. |
| 6 | Blocking Component | Spring-loaded arm to stop pots from sliding back. |
Operating steps
- Positioning: Push the cart so the pots are located between the carrying frame and the placement plate.
- Activation: Turn on the drive motor. The first gear rotates clockwise.
- Linear Motion: The gear drives the racks backward along the sliding plates.
- Lifting Action: As the racks move, the guide sleeves pull the support rods. The rollers on the swing bars climb the inclined plates, forcing the bars to pivot up.
- Transfer: The upward pivot lifts the guide rods, raising the carrying frame and its pots. The backward motion shifts the frame toward the placement plate.
- Deposit: The pots slide or are placed onto the fixed placement plate. The blocking component ensures stability.

Applications
Greenhouse Stock Management
Nursery workers can stack pots on the ground or low benches. The cart lifts and transfers them to higher shelving units without manual climbing or bending, speeding up inventory organization.
Large-Scale Landscaping Installation
During the planting phase, contractors often have hundreds of shrubs waiting for installation. This cart allows a single operator to move batches of pots from the truck drop zone to the planting bed, reducing the need for extra laborers.
Public Park Maintenance
Municipal crews maintain seasonal flower displays. The cart helps swap out dead plants for fresh ones efficiently, keeping park aesthetics high with less downtime for the workers.
Event Setup and Teardown
For weddings or corporate events, floral arrangements are moved in bulk. The motorized lift prevents damage to delicate pots and reduces the physical strain on event staff working long hours.
Where it is less suitable
- Uneven Terrain: The mechanical lift requires a relatively stable base; rough gravel or mud may jam the rollers or misalign the racks.
- Very Heavy Single Pots: The design focuses on multiple medium-sized pots; a single extremely heavy tree might exceed the structural limits of the swing bars.
- Indoor Tight Spaces: The cart’s width and turning radius may be too large for narrow indoor corridors compared to smaller trolleys.
Frequently asked questions
How does the lifting mechanism work?
It uses a mechanical advantage. A motor turns a gear that pushes a rack backward. This rack pulls a lever arm that rides up a slanted ramp. As the arm climbs the ramp, it lifts the frame holding the pots vertically while also moving them horizontally toward the storage plate.
Can it handle different pot sizes?
The carrying frame is designed for specific dimensions. While the patent mentions handling four pots, customizing the frame size allows for various diameters. However, the vertical clearance and horizontal travel distance are fixed by the incline angle and rack length in the design.
Is it battery-powered or plugged in?
The patent describes a drive motor but does not specify the power source. For commercial use, a rechargeable battery pack is typical for mobility. Wired AC power is possible if the cart stays in one location, like a greenhouse bench.
What happens if the power fails during a lift?
The design includes a blocking component with a torsion spring. If the motor stops, the spring-loaded block engages to prevent the pots from sliding backward. Additionally, the friction in the gear-rack system usually resists free-fall, though a brake is recommended for safety.
Is it difficult to operate?
No. The operator simply positions the cart near the pots and presses a button. The machine performs the lift and transfer automatically. Manual pushing is available via the optional transmission mechanism when the motor is off.
Does it require maintenance?
Yes. The rollers and inclined plates need cleaning to remove dirt and debris. Springs should be checked for fatigue, and the motor brushes (if applicable) may need replacement. Greasing the gear track prevents wear.
Can this design be made and sold in the US?
The patent was filed only in China and has lapsed, so it does not restrict the design in the US or in China. However, garden machinery is a crowded field. We recommend a freedom-to-operate check to ensure no other US patents cover the specific gear-rack lift mechanism. See Patent & Production for details.
