The Volvo EC140E Hydraulic Excavator model measures 3" long from the from the back of the track to the front of the tracks. From track to track, the width is 1.75".
The upper side of the vehicle (the cab) is made of metal and can rotate about 270 degrees; everything else is made of plastic. The articulations in the arm can move. The first link of the arm measures about 3.5 inches long from pivot point to pivot point. The second link of the arm measures about 1.75 inches from pivot point to pivot point. Both arm links can move. The scoop also has movement. As you move each articulation the pins (pistons/cylinders) also move accordingly just like on the real thing. The tracks are fitted and can roll.
THIS IS NOT A TOY. It is very small and fragile. It is made mainly for display purposes. This model comes in an individual window box.
