Heavy Vehicles
Shovel car digs the ground
Bulldozer flattens the ground
Dump truck carries soil
All cars are necessary in the construction spot
To end construction as soon as possible
To push forward work as possible safely
Work as many as possible every day
For the happiness of all
Shovel car digs the ground
Bulldozer flattens the ground
Dump truck carries soil
All cars are necessary in the construction spot
There is a role to each car
All cars are necessary in the construction spot
