What is point load of a crane?
Point loads occur when relatively high weights are concentrated on a small bearing area. So; point load on a crane with hooks is a load that is not centered. If you try to pick something up with the end of the crane hook, the load is not centered and would be "point loaded". This type of load will stress the crane cables. When the load falls off the hook-point, the crane cables react - and can break strands of the cable. The crane cable consists of an inner cable and outer cables - so as a load is placed on the cable, it stretches. If this load suddenly shifts or falls, the cables retract quickly and can break. This is dangerous, as you may not notice the inner cable has broke (could be a small bulge in the cable). Using the crane with a broken cable can cause it to fail and drop the load. A stable load is one in which the center of gravity of the load is directly below the main hook and below the lowest point of attachment of the slings. The center of gravity of an object is that point at which the object will balance. The entire weight may be considered as concentrated at this point. A suspended object will always move so that the center of gravity is below the point of support. In order to make a level or stable lift, the crane or hook block must be directly above this point. Thus a load which is slung above and through the center of gravity will be stable and will not tend to topple or slide out of the slings.
Why use high tensile steel?
High tensile steel put simply is used where structures require high tensile strength. Tensile stress is where the forces on a material are "pulling" from each end away from the centre. Steel can be alloyed with certain materials such as aluminum to create a material that is stronger under tensile loading. An example of where high tensile steel is required is the cables of the ANZAC bridge that support its deck. Hope this helps..
What is axial or longitudinal stress?
Axial Stress: A tension or compression stress created in a structural member by the application of a lengthwise axial load.Definition Copyright ©1989 CRC Press LLC. All rights reserved.Examples of tensile axial stress include a chain carrying a load and tension cables on a bridge. Examples of compressive axial stress include decorative columns in architecture and the steel structure of a high rise building.Read more: What_is_axial_stressLongitudinal Stress: In continum mechanics, stress is a measure of the average force per unit area of a surface within a deformable body on which internal forces
What is a hydraulic slip ring?
Hydraulic slip rings are similar to electrical slip rings and transmit fluid power from a stationary source to rotating parts. The hydraulic slip rings are also known as Fluid Rotary Unions (FRU). Fluid pressure is connected from a stationary tube (the stator) to the rotating parts through either single or multi-ported rotating component (rotor) of the slip ring. Multiple application combined slip rings are also wide used to transport not only hydraulic power but also electrical as well as communication cables through a combined slip ring.
What is hydraulic lifts?
Hydraulic lifts utilize a hydraulic piston or ram, typically oil filled, to supply the lifting force for raising or lowering an object/load. These hydraulic systems are usually subdivided by the initial force that drives the hydraulic pump which supplies pressure for the piston. Air/Hydraulics (air over hydraulics) and Electric/Hydraulics (electric over hydraulics) are the two most popular types of power supplies for hydraulic driven systems. Cables and pulleys are often incorporated in hydraulic systems to provide equalization between multiple hydraulic cylinders that must work in unison and to remotely transfer the lifting force to areas where a large cylinder would be impractical to locate.
What is used to stabilize suspension bridges?
Cables .
What kind of bridge is hung from cables?
suspension bridges
What kind of bridge hung from cables?
suspension bridges
What is a kind of bridges hung by cables?
A cable suspension bridge is a kind of bridge hung from cables.
How did the suspension bridge get its name?
Suspension bridges are held, or suspended, from cables above the roadway's surface. This contrasts with bridges whose roadways are supported from underneath.
How is the suspension bridge different from most other modern bridges?
In simple terms, cable stayed use less cables then a suspension bridge. They are a combination of both beam and suspension. Suspension bridges hold the "deck" (where vehicles cross), via the cables, hence the term "suspension"; whereas, a cable stayed has the deck connected via the cables to anchorage points.

What are bridge towers?
Bridge towers are used in suspension bridges or cable stayed bridges. cables, what hold roadway, are fixed there.

What is A type of bridge hung by cabels?
A cable suspension bridge is a bridge hung from cables. These bridges has cables suspended between towers as well as vertical cables.
What bridges use long cables for support?
They are suspension bridges. One of the well known examples is the Golden Gate Bridge in San Francisco.
