Description:

The Dongcheng DZD35 1200W Concrete Vibrator is a professional handheld electric vibration machine designed for concrete compaction, reinforced concrete construction, foundation work and general civil engineering applications.

Powered by a 1200W electric motor, the DZD35 delivers a 4,300 RPM no-load speed, providing rotational power for operating a compatible flexible concrete vibrator shaft and needle assembly.

The machine is designed to assist in the consolidation of freshly poured concrete, helping release trapped air and reduce internal voids when used with a correctly selected vibrator needle and proper compaction techniques.

One of its main features is the 8mm Output Shaft Specification, designed for connecting compatible concrete vibrator shaft assemblies. The output connection size must be matched to the selected flexible shaft before operation.

The Cast Aluminium Head Construction provides a durable front housing suitable for professional construction environments.

Another important feature is the Large Cooling Opening Design, developed to promote motor ventilation and help reduce excessive heat buildup during appropriate operating conditions.

The Rubber-Covered Handle provides a comfortable gripping surface, supporting controlled handling during concrete compaction work.

With a 2.0kg net weight, the DZD35 offers a portable handheld configuration for suitable construction applications.

When connected to a compatible flexible shaft and vibrator needle, the machine can be used during the casting of reinforced concrete slabs, columns, beams, foundations and other structural concrete elements.

The Dongcheng DZD35 1200W Concrete Vibrator is suitable for construction contractors, civil engineering teams, concrete workers, RCC construction projects and professional building maintenance applications requiring portable concrete compaction equipment.

Motor & Performance Specifications:

Manufacturer Specification Note:

Dongcheng’s current official international product page specifies 1200W rated input power, 4,300 RPM no-load speed, 8mm output shaft specification and 2.0kg net weight.

The manufacturer identifies four main features:

1. 1200W Powerful Motor
2. Cast Aluminium Head — Strong and Durable
3. Large Cooling Openings
4. Rubber-Covered Handle for Comfortable Grip

An older Dongcheng product catalogue and another regional Dongcheng website specify 4,700 RPM for the DZD35. This listing uses 4,300 RPM, as shown on the currently linked official international product page. The actual machine nameplate should be checked before publication if the supplied stock is from a different regional version.

The manufacturer does not specify the vibrator needle diameter, flexible shaft length, output vibration frequency, shaft coupling details, rated input voltage or frequency on the referenced page.

Important: The 8mm measurement refers to the motor’s output shaft connection. It is not the diameter of the vibrator needle.

The no-load rotational speed should not automatically be described as the number of vibrations per minute at the concrete needle, since that depends on the compatible vibrator assembly.

Included Items:

Manufacturer-Listed Product & Packaging:

• 1 × Dongcheng DZD35 1200W Concrete Vibrator Motor Unit
• Colour Box Packaging

Accessories to Confirm Before Dispatch:

• Flexible Vibrator Shaft
• Concrete Vibrator Needle
• Shaft Coupling / Connector
• Additional Accessories

Note: Dongcheng’s official product page confirms colour box packaging but does not identify a flexible vibrator shaft or needle in the standard accessory list.

Some distributors sell the DZD35 motor separately, while others offer complete packages with 1.5m or 3m flexible shafts and different needle diameters.

Confirm the exact supplied package before describing the product as a complete concrete vibrator set.

Application & Safety Note:

Connect only a compatible flexible vibrator shaft and needle assembly to the machine’s 8mm output connection, following the manufacturer’s installation instructions.

The flexible needle assembly, not the electric motor housing, is inserted into freshly placed concrete. Use appropriate insertion spacing and duration to avoid inadequate compaction or excessive vibration that could cause segregation.

Keep electrical connections and the motor protected from water, use suitable construction-site electrical protection and follow the manufacturer’s operating instructions. Do not operate without a correctly fitted compatible shaft where the manufacturer prohibits it.
