Minecarts are small vehicles used to transport materials in and out of underground mines. They operate on controlled paths using motors or other mechanisms and can be manually operated. Minecarts have a hinged design and can carry heavy loads, but are limited in the amount of material they can carry.
A minecart is a small vehicle used to transport materials in or out of an underground mine. These wagons often consist of wooden or metal boxes mounted on steel wheels, although designs can vary by region and mining technique. Mining carts carry materials such as iron ore, coal or metals from the ground for processing and can also be used to remove dirt and other waste products. While minecarts in movies are often presented as out-of-control thrill rides, most minecarts actually operate on a very controlled path using motors or other mechanisms.
In many mines, the minecart travels on a series of tracks that are built into the ground. Workers rely on various types of motors to propel these cars along the tracks, although some may be manually operated. Many use a locomotive-style engine which allows multiple minecart units to be connected and pulled with ease. Others use a winch or hoist system, or even a cable system like those used to move workers onto a vehicle for the ride. Specialized minecart pushers can also be used to automatically transfer cars in or out of the mine.
The standard minecart features a hinged design that allows the base of the cart to swing back and forth. This allows workers to easily empty the car and send it back to the mine for refueling. Traditional box or outrigger trolleys feature this type of swivel design, which allows users to manually unload the trolley on either side. Gable mine carts feature a W-shaped design, which can make it easier to roll over heavy loads.
Modern minecart manufacturers often use a slightly different design style to make the unloading process even easier. One side of the cart can hinge open like a door to allow materials to be removed through that side. Others feature a falling bottom or a rear door that can be opened while unloading.
To maximize mining productivity, many mines feature a circular track style, which allows minecarts to travel down the mine while others are traveling back on the same set of tracks. Compared to mechanized mining devices, mine carts are inexpensive and fairly simple to operate. Despite their simplicity, the weight of the materials in a minecart can make them extremely heavy and overburden the miners who have to empty the carts. Since many of these carts are relatively small, they are also quite limited in the amount of material they can carry during each load.
