Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators. it is the small model of excavator work with help of syringes.

Watch the video and learn how to make a homemade syringe operated hydraulic excavator using Wooden sheet, syringes and 12 V DC motor. It’s also called bulldozer.Created mainly from house glue and timber boards, the finished product is really cool.


By the end, the little machine is a fully functional digger, being able to scoop thanks to its ingenious hydraulic system created from household syringes and it can even move around thanks to some basic robotics and remote control gear.
