The frog-type rammer is a compaction machine with a simple structure and easy operation. It works reliably, has high efficiency, is easy to maintain, and is widely used in construction. It can swing flexibly, so you only need to grasp the handle to control the forward or reverse direction of the rammer during work.

[0003] The current frog-type rammer uses an eccentric block on the wheel to produce centrifugal action, which causes the rammer head to reciprocate up and down to perform tamping. Such a wheel structure can easily cause personal injury, and the eccentric block cannot be adjusted to change the tamping force. For this reason, we propose a tamping device for construction projects. Utility Model Content
