I once witnessed on a construction site with a cable trench that was three meters deep, how the construction team got stuck because they couldn't compact the bottom of the trench. That space was so narrow that even a small excavator couldn't turn around. At that time, I brought my frog-type tamper with me. I went down to the bottom of the trench and pulled the starting rope. With a loud roar from the engine, the machine began to jump steadily in the narrow trench. At that moment, I was not only demonstrating the machine, but also showcasing an ability to solve extreme problems.
Why do I highly praise its flexibility? First, please pay attention to its base design. I deliberately designed the tamper plate in this rectangular or smooth geometric shape, just to make it fit the corners and edges of the trench. I found that many so-called "multi-functional machines" are always powerless when facing 90-degree right angles, but the frog-type tamper I control can precisely compact every inch of the land by adjusting the angle of the handle. I reject that cumbersome steering mechanism. I use the rebound force of the machine's jumping to simply push it, and it can complete a turn in place.
I also want to talk about its power transmission system. I gave up the complex hydraulic pipelines because in a narrow space, any leaking pipeline would be a disaster. I insisted on using simple and direct belt transmission or gear transmission. The structure I designed makes the entire machine's center of gravity very concentrated. I found that the more concentrated the center of gravity is, the more stable the machine is when jumping, and it won't have excessive left-right swaying. This means that even in an extremely cramped space, I can ensure that it only exerts force where I want it to.
Every frog-type tamper I exported to various parts of the world embodies my thoughts on "extreme conditions". I not only consider how the machine can enter, but also how it can exit. I designed the handle with a foldable or quick-disassembly function to make it convenient for workers to hoist it into deep pits. You know, true mechanical experts won't just give you a list of parameters. I will tell you how to use this machine to conquer those complex environments that others avoid. I recommend this machine because I personally tried it in those most difficult tasks, and it never let me down.
