With a rated power of 2200W/3HP, speed of 2800 RPM, and voltage of 220V (50HZ frequency), this motor generates the high vibration force needed for heavy-duty concrete work—from high-rise building foundations to dam construction. Its robust design includes a built-in frame for stable placement, a fast heat dissipation system for continuous operation, and a cast iron casing for durability against construction-site impacts. Measuring 435280255MM and weighing 14.5KG, the motor balances portability with stability, while features like one-button start and a high-strength rod enhance user efficiency. Certified for safety and performance, the ZN-70 is engineered to meet the demands of large construction teams and infrastructure projects.
The ZN-70’s 2200W/3HP power and 2800 RPM speed generate exceptional vibration force, capable of compacting high-strength concrete (up to C60) and deep pours (up to 3 meters). The vibration frequency is tuned to eliminate even small air pockets in dense concrete mixes, ensuring the final structure has maximum load-bearing capacity and resistance to cracking. This makes it ideal for critical projects like bridge piers, industrial floors, and high-rise foundations, where concrete quality is non-negotiable.
To support long hours of continuous use (common in large construction projects), the motor is equipped with a fast heat dissipation system—including a large fan cowl and heat-dissipating fins on the cast iron casing. The fan draws cool air through the motor, while the fins accelerate heat transfer, keeping the winding temperature below 150°C (F-class insulation limit) even during 8+ hours of continuous operation. This prevents overheating and extends the motor’s service life, reducing downtime for construction teams.
Unlike portable vibrators without frames, the ZN-70 includes a heavy-duty frame that provides stable placement during operation—eliminating the need for workers to hold the motor continuously. The frame is adjustable, allowing users to position the motor at different angles for hard-to-reach areas (e.g., formwork corners). The cast iron casing adds structural strength, resisting impact from falling tools or debris on construction sites, while the high-strength vibration rod (made of alloy steel) withstands bending and abrasion from concrete aggregates.
The motor features a one-button start for quick activation, reducing setup time and minimizing user error. The power switch is located on the handle, which has an anti-slip grip to prevent accidental drops—even when hands are wet with concrete slurry. Additionally, the motor’s wiring is protected by a durable terminal box with a waterproof seal (IP54 rating), shielding it from moisture and concrete dust. A latch on the frame secures the vibration rod in place, preventing disconnection during operation.
In high-rise building foundations and large commercial structures, the ZN-70’s high vibration force ensures concrete is compacted evenly across thick slabs (up to 300mm) and deep formwork. Its continuous operation capability allows construction teams to pour and compact large volumes of concrete without interruptions, speeding up project timelines.
For dams, canals, and other hydraulic projects, the motor’s ability to compact high-strength concrete (C50–C60) is critical. The vibration force penetrates deep into the concrete, eliminating air pockets that could weaken the structure and lead to water leakage. The frame design allows the motor to be mounted on scaffolding or formwork, making it easy to access large, vertical concrete walls.
Industrial warehouses and factories require thick, durable concrete floors to support heavy machinery. The ZN-70’s 2800 RPM speed ensures the concrete is compacted to a high density, reducing the risk of cracking under heavy loads (e.g., forklifts or storage racks). The fast heat dissipation system allows the motor to be used for 10+ hours a day, covering large floor areas efficiently.
In road and highway projects, the motor is used to compact concrete in pavements, curbs, and median barriers. Its high-strength rod can reach into narrow formwork for curbs, while the frame provides stability on uneven ground. The waterproof design ensures the motor can be used in outdoor environments, even during light rain or wet conditions.
The built-in frame serves two key functions: stability and user comfort. It keeps the motor securely positioned during operation, so workers do not need to hold it—reducing fatigue during long projects. The frame is also adjustable (via locking knobs), allowing the motor to be tilted or raised to reach different areas of the concrete formwork. For vertical applications (e.g., wall pours), the frame can be mounted to scaffolding for hands-free operation.
Yes, the ZN-70 is compatible with most standard vibration rods with a 16mm or 20mm diameter (common sizes for concrete work). The rod connects to the motor via a threaded interface, which allows quick replacement. For deep pours (2–3 meters), we recommend using a 2.5-meter alloy steel rod; for shallow pours (0.5–1 meter), a 1-meter rod is sufficient. Always ensure the rod is rated for 2200W/3HP to avoid damage.
Under normal conditions (20–45°C ambient temperature), the motor can run continuously for 8–10 hours. This is made possible by the fast heat dissipation system, which prevents overheating. If the ambient temperature exceeds 45°C (e.g., hot summer days), reduce continuous operation time to 6–8 hours and allow a 1-hour cool-down period between uses.
The motor weighs 14.5KG, which is manageable for two workers to carry short distances (e.g., between formwork sections). For longer transportation (e.g., across a construction site), the frame includes built-in lifting points that can be attached to a small crane or forklift. The compact dimensions (435280255MM) also allow it to fit in most construction vehicle toolboxes.
First, check the power supply: ensure the 220V outlet is functional and the power cord is not damaged. If the power is normal, inspect the motor’s thermal overload protector—this device shuts off the motor if it overheats. Allow the motor to cool for 1–2 hours, then press the reset button (located on the terminal box) to restart. If the motor still does not work, check the vibration rod connection—loose connections can cause the motor to stall. For persistent issues, contact our technical support team.
