Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.
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.
THIS MODEL . IT CAN BE DISASSEMBLE IN 36 PARTS.
Step 2: TOOLS REQUIRED
Step 3: MATERIAL USED
2. PLY WOOD
3. STEEL SHEET, METAL SHEET
6. NAILS AND SCREWS
Step 4: HOW TO CONNECT SYRINGE

2. FIRST FILL BOTH THE SYRINGES WITH OIL.
3. CONNECT PIPE TO ONE SYRINGE.
4.PRESS THE SYRINGE AND REMOVE THE OIL AND THE PIPE WILL FILL BY OIL.

Step 5: WOOD MODEL
Step 6: AFTER PAINT
1. AFTER COMPLETION OF WOOD MODEL, PAINT THE MODEL .
2. CONNECT SYRINGES TO THE MODEL.
3.AND SET THE REQUIRED MOTION YOU WANT.
Step 7: OIL
THERE ARE TWO TYPE OF SYRINGES
1. SYRINGES CONTAIN RUBBER.
2. SYRINGES LATEX FREE (CONTAIN NO RUBBER)
I HAVE NOT USED THE SYRINGE CONTAIN RUBBER BECAUSE IT WAS NOT AVAILABLE IN MARKET.
HENCE I HAVE USED SYRINGE LATEX FREE (CONTAIN NO RUBBER)
IN SYRINGE LATEX FREE IF WE USE WATER WE WILL NOT GET THE REQUIRED MOTION OF EXTENSION AND RETRACTION
INSTEAD OF USING WATER . I HAVE USED OIL IN IT.BECAUSE OF OIL I GET THE MOTION EXTENSION AND RETRACTION BUT IT WORK SLOW.
