Internal concrete vibrators operate based on the pendulum principle. The drive unit runs at 3,000 revolutions per minute, which is transmitted through a flexible shaft to produce 12,000 vibrations per minute at the poker head. This low-speed output ensures high reliability and an extended service life. These vibrators are compatible with two types of drive units—electric motor or petrol/diesel engine—and are interchangeable. They come with seven standard poker diameters, making them ideal for professional use.
The TPV-SERIES inserting pendulum vibrator pokers are available in lengths ranging from 4 to 12 meters, with bar diameters of 28mm, 32mm, 38mm, 45mm, 50mm, 60mm, and 70mm. Each model is designed for specific applications, offering varying vibration amplitudes and flexible shaft sizes to match different construction needs.
Here is a detailed specification table:
These vibrators are highly versatile, suitable for both small and large-scale concrete projects. Their design ensures efficient compaction, reducing air pockets and improving the quality of the final structure. The range of sizes and configurations makes them adaptable to various construction environments, from residential buildings to commercial infrastructure. Whether you're working with electric or diesel-powered equipment, these pokers deliver consistent performance and durability.
