This is one of Twin City Concrete's trucks. This type of truck is very rare in this area. It can hold 12 yards of concrete.
	This is where the Batch Man sits. The batch man can run the entire computerized plant from this location. The computers keep up with the amount of concrete and aggregate in the hoppers, the amount of water mixed with concrete and the amount of water in the aggregate. They serve many other functions as well.
	This is a picture looking into the underground hoppers that Twin City stores their sand and aggregate in. This allows them to control the environment much better than outside hoppers would. The trucks can drive up a ramp located at the top of the hopper for easy unloading.
	This is a picture of the rear hopper in the underground storage area. This hopper holds the sand so that the chance of it freezing is reduced while it is housed in the rear. You can also see an inovation by Twin City to prevent the sand from clumping and not coming out in an orderly flow. The gate valve senses when the flow of sand is subsiding and activates a vibrator which will loosen the sand particles. This valve prevents the vibrator from running all the time.
	This is a picture of a ventilation pipe at the rear of the underground storage area. This pipe vents out hot air in the summer and lets in warm air in during the colder months. This pipe is one left over from a previous assignment and is utilized in this manner instead of allowing it to sit dormant.
	This is a picture of a tank filled with gravel, which is located toward the end of the conveyor running out of the underground storage area. This prevents the conveyor belt from coming into contact with the gate of the hoppers when the belt is turned on.
	This picture is of a cement truck loading the hopper which contains the cement mixture. The cement is injected into the hopper through a pressurized hose which sends it all the way up to the top. The cement is then mixed into a slurry and lowered into a holding tank. When a truck is ready, the cement can be loaded immediately, because it has already been weighed.
	This picture is the holding area where Twin City's trucks empty any remaining concrete. The cement and aggregate go to the bottom, which leaves usuable water for adding to the trucks. They sell the heavier items to local contractors as fill material.
