Needle Vibrator Petrol – 6HP Lifan Drive, Takes 35 to 70mm Needles

The Jamshedji 6 HP petrol needle vibrator is a Lifan-engined concrete vibrator that spins a flexible-shaft poker needle to drive trapped air out of freshly poured concrete. Like the 7.5 HP unit it runs anywhere without a power supply and takes needle dies from 35 mm to 70 mm — a well-balanced general-purpose site drive. Weight 20 kg, 3 litre tank, roughly 75 minutes running per litre.

Why concrete has to be vibrated

Freshly poured concrete is full of trapped air. Left in place, those voids become honeycombing and weak points that cut the strength of the finished pour and expose the reinforcement to corrosion. A needle vibrator is dropped into the wet concrete and its high-frequency vibration liquefies the mix momentarily, letting the air rise out and the concrete flow tight around the bars and into the corners of the formwork. Proper vibration is the difference between concrete that reaches its design strength and concrete that does not.

Drive and needle — how the system works

A needle vibrator is two parts: the drive (the engine that generates the power) and the needle (the poker on a flexible shaft that goes into the concrete). The two are chosen separately — the drive for the power and portability the site needs, the needle diameter for the pour.

This 6 HP petrol unit runs on a reliable Lifan engine and, like the larger drive, needs no mains supply or cable — so it works on any site. It sits just below the 7.5 HP flagship on power while covering the same wide needle range, which makes it the sensible general-purpose choice for most site pouring.

Which drive for the site

Choose the drive by power supply and the scale of the pour.

• 7.5 HP petrol drive — the most powerful, for the largest slabs, mass foundations and stiff, heavily reinforced mixes.
• This 6 HP petrol drive — cable-free petrol power for general slab, beam, column and foundation work; the everyday site vibrator.
• 3 HP single-phase electric drive — where a mains supply exists and no exhaust is wanted, such as enclosed or indoor pours.
• 950 W and 1300 W portable vibrators — light, hand-carried units for columns, small pours and confined spaces.

Matching the needle to the pour

This drive accepts needle dies from 35 mm to 70 mm. A bigger needle drives more energy over a wider radius for mass concrete; a smaller needle fits between congested reinforcement and into narrow sections. Needles are sold separately so you can match the diameter and hose length to the job:

• 35 mm × 6 m — narrow sections and congested rebar
• 50 mm × 4 m and 50 mm × 6 m — general slabs and beams
• 60 mm × 4 m and 60 mm × 6 m — heavier mass concrete
• 70 mm × 6 m — the largest pours

Applications

Slab casting, RCC beams and columns, foundations, and general site concrete work — anywhere a reliable cable-free drive is needed for day-to-day pouring.
