The Volvo GNBH23 one-way flat plate vibrating rammer has the following advantages: 1. high efficiency: the rammer adopts one-way flat plate vibration technology, which can quickly compact the ground with high-speed vibration. Compared with the traditional manual tamping method, the efficiency is significantly improved. 2. Labor-saving: When using the Volvo GNBH23 one-way flat plate vibrating rammer, the operator only needs to place the tamper on the ground and start the vibration device. Do not need to carry out cumbersome physical labor, greatly reducing the workload. 3. uniform tamping: rammer using flat plate vibration mode, in the vibration can be uniformly transferring power to the ground, so that the ground is uniformly compacted. Can be in a shorter period of time, to achieve better tamping effect. 4. strong applicability: whether soil, sand or gravel ground, Walworth GNBH23 one-way flat plate vibration tamper are able to effectively tamping. Wide range of application, can be used for roads, bridges, housing foundations and other construction projects. 5. Simple operation: Volvo GNBH23 one-way plate vibrating rammer adopts compressor or hydraulic motor as the power source, it is very simple to start, stop and adjust the vibration frequency. The operator can easily master the operation skills. In a word, Volvo GNBH23 one-way plate vibrating rammer has the advantages of high efficiency, labor-saving, even tamping, strong applicability and simple operation, etc. It is an ideal tool to improve the tamping efficiency in engineering construction.
