A brief introduction to the difference between brushed and brushless versions.

The brushed version has less walking strength and can only play on flat roads.
The brushless version is powerful and can be played on ordinary shallow mud and sand.

The entire frame and body are all welded steel plates, and the crawler is made of open molds.
All metal materials in the structure part, and the paint is made by professional factory batch baking paint.The boom and small boom buckets are hydraulically driven. The walking rotation is driven by a motor.

3D printed cab. The structure is more realistic.

The maximum pressure of the power oil pump can reach 10 pressures, but the pipe can't stand so much,
Therefore, it is safer to control the working pressure within 5 pressures, and it will not burst the pipe.
The oil pump comes with an adjustable relief valve.

The whole machine is made in batches in factories, not in small workshops. Good quality and not easy to damage.

The body can carry 150 pounds and can travel on flat roads. The strength is very strong, and the big arm can easily lift a bucket of water without any problem.
The following are actual pictures:
