Portable Needle Vibrator – 950W, 35mm Integrated Poker

The Jamshedji 950 W portable needle vibrator is a lightweight, hand-held electric concrete vibrator with an integrated 35 mm poker — an all-in-one unit that plugs into ordinary single-phase power and weighs just 2 kg. Unlike the engine and motor drives that take separate needles, this is a self-contained tool for columns, small pours and confined spaces where a full drive is too heavy to handle. 4,300 rpm, 3.7 A.

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 pushed 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.

An all-in-one tool, not a drive-plus-needle

The petrol and 3 HP electric machines are drives: a separate engine or motor connected to an interchangeable needle by a flexible shaft. This portable unit is different — the motor and the 35 mm poker are built into one hand-held tool. There is no separate needle to buy or match.

That makes it light (2 kg) and instantly usable — plug it into a normal socket and work. The trade-off is that it is a fixed 35 mm needle at lower power, so it is made for smaller, tighter work rather than mass concrete: columns, beams, small slabs, repair pours and anywhere a full drive is awkward to carry or manoeuvre. Its high 4,300 rpm gives fast, effective consolidation in those smaller sections. On the biggest pours, the petrol and 3 HP electric drives remain the right tools.

Where it fits in the range

• This 950 W portable — the lightest unit, integrated 35 mm needle, for columns, small pours and confined spaces.
• 1300 W portable — the same hand-held format with more power for slightly heavier portable work.
• 3 HP single-phase electric drive — a full drive taking interchangeable 35–70 mm needles, for larger indoor and mains-powered pours.
• 6 HP and 7.5 HP petrol drives — cable-free power for large pours on sites without electricity.

Applications

Columns and beams, small and repair slabs, footings, precast and formwork pours, and any small-scale or confined concrete work where a light, plug-in vibrator is easier to use than a full drive.
