Profile
As a kind of special-purpose lifting equipment, shipbuilding gantry crane is used at dockyard or slipway of ship build yard. Shipbuilding gate cranes are sometimes called Goliath crane in English. Goliath is the name of the giant in Bible. Latter, it is referred to mobile giant crane. What is the characteristic is that it has a larger span, higher height. Generally, the span of shipbuilding gantry crane can reach more than 40 m and the max. span of the shipbuilding gantry crane can reach 200 m. The height under the main girder can reach 40-80 m. Because it has a large span, one side of the portal adopts rigid supporting leg and the other side adopts flexible supporting leg. in other words, the side which adopts rigid supporting leg joints with the main girder solidly. And, the other side which adopts flexible supporting legs joints with the main girder by flexible hinge. In accordance with the requirement of shipbuilding technology, the shipbuilding gantry crane has following functions, such as handling the materials with single hook, handling the materials with double hooks, handling the materials with three hooks, turning over the body section in the sky, small volume angle spinning and other multiple functions. Especially, it can satisfy the requirement of turning over and gathering up of body section. In order to complete the described function, generally, the shipbuilding gantry crane is carried with up and down two trolleys.
And, the up and down two trolleys will run in separate railway. On the up trolley, it mounts two lifting mechanism, which has the same lifting capacity. The suspension centre of the lifting mechanism locates on outside of the main girder separately. The two lifting mechanism can be operated for its separated purpose or the two lifting mechanism can be operated together to handle the materials, which can complete the spinning of the body section and the hoisting of the body section. Both hooks mounts transverse mechanism, which can complete the horizontal movement separately. Generally speaking, the distance of horizontal movement can reach 1.5 m or 2 m. Thus, it can realize the fine adjustment and fine spinning. It can be accurate when the body section is closed. The under trolley equips with main hook and auxiliary hook. The two hooks is set in the middle of position of the main girder. The main hook can individually lift the body of the ship. Also, it can complete the lifting operation with three hooks combining with the hook of the up trolley. Generally, the lifting capacity of auxiliary hook of the trolley is small, but the lifting speed of the auxiliary is quick. It can lift some small components. In according with the coordination action among the two hooks of the up and down trolley, the main hook of the down trolley and the traveling mechanism of the up and down trolley, it can realize the turning over of the body of the shipbuilding gantry crane in the air.

Main technical parameter
It has following advantages, such as, lifting the body of the ship with single hook, hoisting, turning over the body of the ship in the air, horizontal slight spinning in the air
The portal has two type, double girder and single girder, which can be chose by user. In order to make use of the materials reasonably, the main girder adopts variable cross-section optimal design.
The rigid supporting leg of the portal has two types, single column type and double column type, which can be chose by user.
The up trolley sets with double main hooks, which is set on both sides of the main girder, but it can realize individual horizontal movement or move the two hooks at the same time, 0~2m.
The down trolley sets two hooks, main hook and auxiliary hook, which is mounted under the centre of the girder.
The up and down trolley can realize mutual cross operation
All the lifting mechanisms and traveling mechanism adopt frequency control.
On the side of the rigid supporting legs and on the top surface of the main girder is mounted tumbler crane for maintaining, which aims to maintain the up and down trolley.
The elevator is mounted on the inner side of the rigid supporting leg, which aims to make it convenient to get on the shipbuilding gantry crane.

- Q: I'm not voting for him but I respect the fact that he knows insanity when he sees it.
- We just spread butter and sprinkle garlic powder over the butter, toast lightly (not garlic salt).
- Q: I understand why positive g's damage the wing, or rest of the plane, but why is there a limit for going into negative g's? doesn't a negative g put less weight to no weight on the planeIs it because a negative g is putting force on the wings in the opposite direction? towards the ground?
- There are lots of different kinds of welders, some work underwater, some high up in building construction, some on carsMy husband learned to weld as part of his training in metal sculpture and could weld a boat hitch, when it needed fixing, tooAnother welder we know does both welding and sculpture depending on what kind of work is availableYou can't pick a career by the payBesides, lots of doctors, optometrists, pharmacists now work in clinics owned by large corporations and they are salaried while the doctor you know has his own practice and can see more people, work longer hours, specialize to earn moreThe cost of living for an area will have an affect on how well you liveHow much you earn depends on training, the kinds of work where you live, and the economics of the region Go to the Bureau of Labor Statistics and look up both fields and you can make a comparisonA welder can learn his craft within a short time, depending on how easy it is to manage the materials and can learn other types of welding which might take years to perfectA doctor will have 4 years of college, medical school, internship, residency (for specialties), etc Do you want to touch sick people? Put things together? Completely different skills in most areas.
- Q: It attaches to the truck, it's not the actual truckIs it like a trailer or something? But it's kind of small and a few people can sit in the back and it's coveredI don't even know if it has a name, but if soI don't know dude.
- On a pickup truck, there are two main parts to the bodyFirst is the cab, which is the part where everybody sitsThen there is the bed, which is the open back part where you can put stuffThe bed has a gate which opens and closes to allow easy accessThis is known as the tailgateThe tailgate is often used for sitting when openedTailgate parties often happen in and around the tailgateBut what you're saying is that this thing people sit on is detached? That sounds pretty dangerousHere's what I think you might mean: 1) A box capThese are the like boxes that cover up the bed of the truckYou can't legally fit passengers in them, but you can sit there when the truck isn't going anywhere 2) A cherry pickerThis is like a big crane on the back of the truck that has a bucket where a person or maybe two can stand and do work fromUsually seen on phone/cable trucks, construction vehicles, and firetrucksUsually not covered thoughI really can't think of anything else that you might mean.
- Q: The figure shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass m1 75.00kg and length L 6.000m is supported by two vertical massless stringsString A is attached at a distance d 1.100m from the left end of the bar and is connected to the top plateString B is attached to the left end of the bar and is connected to the floorAn object of mass m2 2500kg is supported by the crane at a distance x 5.800m from the left end of the barThroughout this problem, positive torque is counterclockwiseUse 9.81m/s^2 for the magnitude of the acceleration due to gravity.
- Use a brown envelope then the money doesn't need to be wrapped in anythingWouldn't you normally insure money if you are posting it anyway? So that it wouldn't matter if someone stole it anyway?
- Q: A crane lifts the 24000 kg steel hull of a ship out of the waterWhat is the tension in the crane's cable when the hull is submerged in the water? What is the tension when the hull is completely out of the water? Thank you.
- The density of steel is 7.85 g/cm^3 or 7.85x10^3 kg/m^3Therefore the volume of steel in the ship is 24000/7.85x10^3 3.06 m^3The bouyancy of this much water displaced when the ship is submerged is 3.06(1.00x10^3)(9.8) 30.0x10^3 NTension in cable when ship submerged 24000(9.8)-30.0x10^3 205,200 NTension when ship out of water 24000(9.8) 235200 N.

- Q: I am writing captions for some construction picturesMy notes say, quot;The girder that is not bearing on one end is the 50-ton lift.quot; What does this mean? What is a girder that is not bearing on one end?
- It is one that is attached at one end onlyA 50 ton lift could be a crane capable of lifting 59 tons or it could be a beam that weighed 50 tons when it was lifted into place A cantilever beam is the term for a beam that is attached only at one end.
- Q: And liberals think Romney's wealth, house elevator and female body parts are the issues in this election?Best answer will go to the person with the best disposal solution for liberalsThey no longer have a function in American society.
- That's easyWeaponsThink of all the money we'd save on bombs and welfare if we dropped liberals on our enemiesA body falling at 120mph will ruin your day for sureNot to mention terrify you beyond beliefHuh, brings a whole new meaning to the term smart bombIn this instance it would be Harvard gradsBy the way, Ann Romney has MSHence the elevatorShe's only going down hill and I for one don't fault a person for doing whatever they can to help that if they have the means.
- Q: I am renting from a place right now and haven't been here longOur AC has gone out (6/29/07) and they still haven't fixed or replaced it yetThey said that they quot;ordered us a new one NOWHow hot does it have to be to be considered to hot for small childrenWe have had so many hot days and sweat pour off of my children (age 3.5 and 1) and IIt has already been over 95 degrees in just the downstairs and everyone knows that heat goes upOur bedrooms are upstairsWhat can I do? We have already bought 8 new fans and it is still to hot in our houseIf anyone could please help me, please dueI will need to see the exact law on it so I have proof and maybe use it to get out of our lease because this is getting crazyThank you!
- I don't know about VA, but I know in NY there's no law requiring a landlord provide air conditioning - it's just a law that a landlord provide heat Good luck!
