Ningbo Tongque Machinery Manufacturing Co., Ltd. (FLONPRO) is a professional Gasoline Vibrator Engines manufacturer with 15 years of experience in power tools and concrete equipment. We supply self-contained gasoline-powered drive units designed to operate concrete vibrator pokers on construction sites where mains electricity is unavailable or impractical. Our range targets infrastructure projects, bridge decks, dam construction, precast yards, and remote-area pours that demand reliable compaction without cord constraints.
As an export-oriented factory operating a 10,000 m² facility near Ningbo and Shanghai ports, we manufacture gasoline vibrator engines under strict quality control from raw material inspection to final assembly. We offer OEM and ODM services to adapt engine displacement, mounting interface, shaft coupling, and fuel system to your brand specifications. Every unit is configured around the working point, material mix, and production target you define.

Application Fit and Workpiece Considerations
Gasoline vibrator engines are the preferred power source for concrete consolidation when site power is absent, unreliable, or too distant. Typical scenarios include:
- Remote infrastructure – bridge abutments, highway barriers, tunnel linings where generator sets add cost and logistics.
- Precast yards – mobile operators moving between moulds without trailing cables.
- Repair and retrofit – confined spaces where corded vibrators create trip hazards.
- High-slump and low-slump mixes – engine speed control allows the operator to match vibration frequency to concrete workability.
The engine mounts directly to a flexible shaft assembly that drives the poker head. We supply the complete drive unit including the centrifugal clutch, throttle control, and frame. The customer selects the poker shaft and head separately based on the required insertion depth and poker diameter.
Critical Specifications and Performance
Each gasoline vibrator engine is built around a four-stroke, air-cooled petrol engine. Key parameters we confirm during configuration:
- Displacement and power – selected to maintain rated poker frequency (typically 12,000–14,000 vpm) under load.
- Fuel system – diaphragm carburettor for operation at any angle; optional primer bulb for cold starts.
- Clutch engagement speed – set to prevent belt or shaft slip during startup.
- Vibration isolation – rubber mounts between engine and frame reduce operator hand-arm vibration.
- Noise level – standard exhaust with optional spark arrestor for use in fire-sensitive areas.
Configuration Options and Automation Integration
We configure each drive unit to match the customer’s poker system and site workflow. Options include:
Shaft coupling
Quick-connect or threaded adaptor for standard 20–30 mm flexible shafts.
Throttle control
Fixed-speed lever or variable-speed trigger for precise frequency adjustment.
Frame design
Tubular steel frame with rubber feet or roll cage for rough handling.
Fuel tank
Standard 0.8 L or extended 1.2 L for longer runtime between refills.
For automated precast lines, we can integrate a remote stop/start solenoid and tachometer output for PLC monitoring. The engine can be mounted on a trolley or fixed pedestal depending on the production layout.
Installation, Acceptance and Maintenance
Every gasoline vibrator engine is test-run before dispatch. We provide a run-in procedure and a recommended maintenance schedule covering oil change, air filter cleaning, and clutch inspection. Installation is straightforward: mount the unit on a stable base, connect the flexible shaft, fill with fuel and oil, and start. No specialised tools are required.
Acceptance testing can be performed at our factory or witnessed by your inspector. We document no-load speed, clutch engagement point, and vibration frequency at the poker end. Spare parts such as air filters, spark plugs, clutch shoes, and throttle cables are kept in stock for fast dispatch.
Quality Assurance and Compliance
Our manufacturing process follows end-to-end quality management: incoming material inspection, in-process checks during assembly, and final functional test on every unit. The engines comply with CE requirements and applicable international safety standards. We also offer custom certification documentation for specific destination markets.
Information We Use to Configure Your Solution
To prepare a precise quotation and configuration, we need the following project data:
| Parameter |
Why We Need It |
| Poker diameter and length |
Determines required engine power and shaft torque |
| Concrete mix design (slump, aggregate size) |
Influences optimal vibration frequency and amplitude |
| Daily pour volume and shift duration |
Defines fuel tank capacity and runtime requirements |
| Site conditions (altitude, ambient temperature) |
Affects carburettor jetting and cooling performance |
| Mounting preference (trolley, fixed, roll cage) |
Ensures frame design matches operator mobility needs |
| Target markets and required certifications |
Allows us to prepare CE, EPA, or other compliance docs |
With this information we select the correct engine model, configure the clutch and shaft coupling, and propose a complete drive unit that meets your production and compliance requirements.
Frequently Asked Questions
What fuel do your gasoline vibrator engines use?
All our models run on regular unleaded petrol with a minimum octane rating of 90 RON. We recommend using ethanol-free fuel where available to extend carburettor life. The engine oil is SAE 10W-30, changed every 50 operating hours.
Can I use your engine with my existing poker shafts and heads?
Yes. We offer a range of shaft couplings that adapt to standard flexible shaft diameters (20 mm, 25 mm, 30 mm). Provide us with the shaft end fitting type and diameter, and we will supply the matching coupling.
What is the typical runtime on a full tank?
With the standard 0.8 L tank, runtime is approximately 45–60 minutes at continuous full load. The optional 1.2 L tank extends runtime to 70–90 minutes. Actual consumption depends on engine load and ambient conditions.
Do you provide OEM/ODM services for gasoline vibrator engines?
Yes. We offer full OEM and ODM services including custom colour, branding, packaging, and modifications to the engine displacement, frame design, and control layout. Contact us with your specification sheet for a feasibility review.
What is the warranty period and spare parts availability?
We provide a standard 12-month warranty against manufacturing defects. Spare parts such as air filters, spark plugs, clutch assemblies, and carburettor kits are stocked and can be shipped within 3–5 working days.
How do you ship gasoline engines internationally?
Engines are shipped with fuel drained and oil removed to comply with IATA/IMDG regulations. We pack each unit in a reinforced carton with foam inserts. Shipping terms include FOB, CIF, CFR, and EXW from Ningbo or Shanghai ports.
