Q:why is the crane an important invention?
A crane allows us to place light or heavy loads with precession and safety; on top of buildings, across water ways, down mine shafts and over obstacles. Building a pyramid today would be done with cranes, instead of building ramps to slide the massive stone blocks up. Cranes speed up any construction project. Cranes eliminate a lot of manual labor. Cranes prevent injuries by doing the hard work. One example, we used a crane to lift off an entire house roof, in one piece. We then built a second story and then used the crane again to put the roof back on. Without a crane, it would have taken several days to tear off the shingles, remove the roof sheeting and the trusses, not to mention the money saved. The building codes do not allow the reuse of wood trusses, yet not taking the roof apart, allowed use to reuse the trusses, a savings of hundreds of dollars. Wingman
Q:what is crane rigging?
Wire rope is twisted line made of stainless, or high tensile steel. Rigging refers to the slings, or chains that attach the load to the lift hook. Rigging also refers to the act of attaching a load to a load handling device, such as a crane.
Q:How do you get a crane down from a tall building once it's completed?
In the US most are called Tower Cranes and they actualy lower them selves down part way then using Mobile Cranes they diss asemble them the rest of the way
Q:method how to assemble tower crane?
Generally tower cranes are self erecting. The first mast and jib sections are assembled at ground level. The mast and jib are then jacked up and another mast section inserted. If the tower crane is not self erecting then mobile cranes have to be used to assemble the crane.
Q:Is the working load of a crane the maximum weight it is able to lift?
Usually there is a safety factor of 400% built into all engineered cranes. This is to account for unforeseen momentary spike loads, operator errors and component weaknesses ( (chipped tooth or poor forged parts or chains, etc) This is to take into account shock loads, for instance if you were picking up a bundle of steel bars and the load shifted and the bars dropped a foot or so the momentary load on the crane spikes. Working load is basically the load the crane is designed to run all day long at. If you run at the design load the crane is covered under the manufacturer's guarantee against defects and the maker is liable for problems or failures associated with the crane. But for example if the manufacturer can demonstrate you were picking up a 5 ton load on a regular basis with a crane rated at 3 tons, the manufacturer's liability is negated. Since you can counterweight any crane enough to theoretically lift anything, most of the cranes that have electric motors actually will stall if you lift much over the design weight. In other words in the above crane if you try to pick up 5 tons with a 3 ton crane, the motor will not have enough horsepower to pick up the weight and the motor will simply not lift it. The actual overload factor built into a crane is usually to contend with those shock loads and defective or weak components not seen.
Q:carribean crane jobs?
As okorder.com/ When completed Trinidad will have the largest Conference Centre in the Caribbean. This is just the latest of new tall buildings the Government of TT is building in Port of Spain.
Q:What do lattice boom and hydraulic boom in cranes mean?
LATTICE BOOM: See first link. This is where the boom (the portion used to support the load) is made like a lattice ... i.e. interconnected trusses and girders. The cables for lifting the load are run from the base of the boom to the load over pulleys/gears located at the boom's tip. The boom itself is NOT adjustable in length or in angle. HYDRAULIC BOOM: See second link. This crane uses hydraulics to adjust either the length of the boom, or the angle at which the boom joints intersect. It looks more like a single beam construction, although its probably closer to a tube type design (hydraulics may be inside or outside the arm). The load is raised/lowered by cables operating at the end of the boom ... not necessarily tied back to the bottom of the boom.
Q:What is the process for sizing a crane?
It okorder.com and view some of the product guides and review the performance data and load charts. It also depends on what type of support soil or foundation that is capable of supporting the crane.
Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
Standard number: GB/T 5031-2008Standard Name: Tower CraneStandard status: currentAlternatives: instead of GB/T 17806-1999; GB/T 17807-1999; GB/T 5031-1994; GB/T 9462-1999This standard specifies the nomenclature, classification and identification, technical requirements, test methods, inspection rules, information identification, packaging, transportation and storage, installation and climbing, and inspection of tower cranes.
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:
