An emergency switch in Japan. On railways, [1] an emergency stop is a full application of the brakes in order to bring a train to a stop as quickly as possible. [2] This occurs either by a manual emergency stop activation, such as a button being pushed on the train to start the emergency stop, or on some trains automatically, when the train has passed a red signal or the driver has failed to ...
Some other systems used to safeguard the conveyor are belt sway switches, speed switches, belt rip switch, and emergency stops. The belt sway switch will stop the conveyor if the belt starts losing its alignment along the structure. The speed switch will stop the belt if the switch is not registering that the belt is running at the required speed.
Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases. The rotating part of the conveyor is sometimes called simply an auger.
A conveyor system is often the lifeline to a company's ability to effectively move its product in a timely fashion. The steps that a company can take to ensure that it performs at peak capacity, include regular inspections and system audits, close monitoring of motors and reducers, keeping key parts in stock, and proper training of personnel.
Bags are placed on some type of conveyor belt in a secure area not accessible by passengers. In a single-level system, the belt will deliver bags into the terminal from an opening in the wall. The belt generally runs along the wall for a short distance and then turns into the terminal forming a long oval that allows many passengers to access ...
Interest in dead man's controls increased with the introduction of electric trams (streetcars in North America) and especially electrified rapid transit trains. The first widespread use came with the introduction of the mass-produced Birney One-Man Safety (tram) Car, though dead-man equipment was fairly rare on US streetcars until the successful PCC streetcar, which had a left-foot-operated ...
There have been several proposals to replace the line with moving walkways or conveyor belts. In 1923, H.S. Putnam proposed to replace the shuttle with an endless moving platform system. There would have been three platforms with speeds of 3 miles per hour (4.8 km/h), 6 miles per hour (9.7 km/h) and 9 miles per hour (14 km/h).
The difference between drag conveyors, scraper conveyors, and flight conveyors largely depends on whether the chain links have obvious flights or paddles attached. [4] In a drag conveyor, the chain moves the material directly, while a flight conveyor uses a series of wood, metal, or plastic flights attached to the chain at regular intervals ...
