Concrete Vibrator Poker Shaft – FLONPRO Range
Ningbo Tongque Machinery Manufacturing Co., Ltd. (FLONPRO) is an export-oriented Concrete Vibrator Poker Shaft manufacturer with 15 years of experience in power tools and concrete equipment. We supply a complete line of poker shafts for internal concrete vibration, covering the most common regional coupling and pin-type interfaces used in Malaysia, Indonesia, Korea, Japan, and China. Our shafts are designed for reliable consolidation of fresh concrete in precast yards, bridge decks, foundation work, columns, beams, and slabs. Every shaft is produced in our 10,000 m² facility near Ningbo Port, with end-to-end quality control from raw material inspection to final assembly. We support OEM and ODM projects, and we prepare each proposal based on the working point, material, and production target.

Application Fit and Workpiece Considerations
Concrete vibrator poker shafts are selected primarily by head diameter, shaft length, and coupling type. The head diameter determines the radius of action and the maximum aggregate size that can be consolidated. For standard structural concrete with 20–40 mm aggregate, a 38 mm head is common; for congested reinforcement or thin sections, 25–32 mm heads provide better access. Shaft length is matched to the depth of the pour, typically 2–6 m. We supply shafts with flexible hose and inner core cable that transmit vibration from the drive unit to the poker head without excessive heat build-up.
- Material: Outer hose is abrasion-resistant rubber or polyurethane; inner core is high-tensile steel wire; poker head is hardened steel.
- Critical specifications: Frequency range 120–200 Hz (7,200–12,000 vpm), amplitude 1.0–2.5 mm, centrifugal force 200–1,000 kg.
- Capacity: A single shaft can consolidate 5–20 m³ per hour depending on head size and concrete slump.
Configuration and Automation Integration
We configure each poker shaft assembly to match the drive unit (electric motor, gasoline engine, or high-frequency converter) and the site’s coupling standard. For automated precast lines, we can integrate the shaft with a fixed mounting bracket and quick-disconnect coupling to reduce changeover time. The shaft is balanced at the factory to minimise operator fatigue and bearing wear. We do not supply the drive unit as part of this category, but we can recommend compatible units from our Concrete Vibrator Shafts range or the Portable Concrete Vibrator category.
Installation, Acceptance and Maintenance
Installation is straightforward: connect the shaft coupling to the drive unit, secure the hose clamp, and verify free rotation of the core before first use. Acceptance testing includes a no-load run for 2 minutes to check vibration amplitude and noise level. We recommend greasing the core every 50 operating hours and inspecting the hose for cuts or abrasion. Spare parts (core cables, hoses, couplings, heads) are available for all types.
Quality Assurance and Compliance
Every shaft undergoes in-process inspection of the core wire tension, hose thickness, coupling fit, and final vibration test. Our quality system covers incoming raw material (steel, rubber, couplings) and finished product performance. We comply with CE and relevant international safety standards for construction equipment. Documentation includes material certificates, test reports, and a packing list.
Information We Use to Configure Your Solution
To prepare a precise quotation and shaft configuration, we need the following project data:
- Required head diameter (mm) and shaft length (m)
- Coupling type: claw, pin, threaded, or other (please specify market)
- Drive unit type and output frequency (if known)
- Expected concrete mix (max aggregate size, slump)
- Production volume (pieces per order, annual estimate)
- Packaging preference (bulk, individual carton, pallet)
- OEM/ODM requirements (branding, colour, labelling)
Frequently Asked Questions
Q: What is the typical lead time for a custom poker shaft order?
A: For standard types (Malaysian, Indonesian, Korean, Japanese, Chinese), lead time is 15–25 days after order confirmation, depending on quantity and material availability. Custom lengths or special couplings may add 5–10 days.
Q: Can you supply poker shafts with a different hose colour or branding?
A: Yes. We offer OEM and ODM services. You can specify hose colour, imprint your brand logo on the hose or coupling, and choose custom packaging. Minimum order quantities apply for custom branding.
Q: Do you test each shaft before shipment?
A: Every shaft is run-tested for vibration amplitude, noise, and coupling fit. A sample test report can be provided with the shipment. We also retain batch samples for traceability.
Q: What is the maximum shaft length you can produce?
A: We can produce shafts up to 8 metres in one piece. Longer lengths can be supplied with intermediate couplings. Please confirm the required length when requesting a quote.
Q: Which drive units are compatible with your poker shafts?
A: Our shafts are compatible with most electric vibrator motors, gasoline engines, and high-frequency converters. We can also supply matching drive units from our Concrete Vibrator Shafts and Portable Concrete Vibrator lines. If you have an existing drive, please provide the coupling dimensions and we will confirm fit.
