How does a monorail move

Shock absorbing mechanisms are in place to allow the compartments to move at slight angles on all sides to compensate on weight and turns. Click on Deccan Chronicle Technology and Science for the latest news and reviews.

A monorail track is usually less expensive to build than a comparable elevated conventional rail line of equal capacity.

Due to a smaller footprint, they are seen as more attractive than conventional elevated rail lines and block only a minimal amount of sky. Monorail is, by design, a grade-separated system.

They do not interfere with existing transport modes. Disadvantages Monorail vehicles are not compatible with any other type of rail infrastructure, which makes for example through services onto mainline tracks impossible.

Monorail tracks do not easily accommodate at-grade intersections. In an emergency, passengers may not be able to immediately exit because an elevated monorail vehicle is high above ground and not all systems have emergency walkways. The passengers must sometimes wait until a rescue train, fire engine or a cherry picker comes to the rescue. Newer monorail systems resolve this by building emergency walkways alongside the entire track, at the expense of visual intrusion.

Suspended railways resolve this by building aircraft-style evacuation slides into the vehicles. Japanese systems use the next train to tow broken down trains to the next station, but this has yet to occur. Gantry crane — Also called floor-supported or free-standing, the bridge for these cranes is supported on two or more legs running on fixed rails in the facility floor, or on wheels.

A variety of types are available, depending on the configuration of the facility: Cantilevered Semigantry Single leg Double leg End effectors or below the hook equipment : A variety of different, application-specific, attachments can be added to the trolley or hoist to handle the lifting or positioning of different loads. A motorized hook rotator powers the rotation of the hook attached to the bottom block of a hoist for additional load control.

Gripping lifters use either friction or indentation-causing pressure to hold a load. Tong grabs or clamps utilize a scissor-type action to grip a load. Coil grabs grasp the outer diameter of a coil via tongs or gripping mechanisms to lift or turn it. Mechanical lifters are composed of two or more rigid parts that move in tandem when manually actuated to secure the load.

Vacuum lifters utilize an electric-powered extraction pump and sealed pads to create a vacuum to attach the lifter to an object. Sheet lifters use two claws to grab a load of sheet metal or wood by wrapping around the edges. A lip on the lower portion of the claws prevents the sheet from falling out of the lifter.

Pallet lifters use forks to lift pallets from underneath. Magnets lift, carry or release flat or round ferrous objects with or without an electrical power supply.

Slings or strap hoists made of nylon, polyester, wire rope or chain lift materials that are too large and bulky to be transported any other way, such as steel coils or sheets. Drum turners turn over drums for filling and emptying. Monorail systems and workstation cranes are used in a variety of areas to support processing and handling throughout a facility: Assembly: Moving products through production processes Positioning: Securing a component for additional work Transportation: Loading finished products onto open trailers or railcars Staging: Holding work-in-process for additional production processes Storage: Transporting heavy items to and from storage areas Warehousing: Moving large, heavy products to and from docks.
