1. The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.  
4. It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
5. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
6. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
7. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

Q: HSE Officers can better answer this question or a qualified Crane operator it self can explain.
each crane is so different. it depends on the rated crane load, the lifted distance from the crane and actuall load to be lifted. Each crane an envelope of angles to the horizontal, lifted load, and distance from the crane. The crane operator must insure that he is within this envelope or the crane may topple over. Also, the wind at the time of the lift must be considered. If you can picture a seesaw with loads pivoting about a fulcrum. When two people are on the seesaw, one person is the crane and the other is the load to be lifted. Only in the case of a crane, the fulcrum is at the crane itself with a large dead load counter weight behind the cab operator.
Q: I have a vessel 40 feet off the ground in a platform, and the crane can get to within 30 feet of it (from the side). I'm more curious of the process for sizing them though.
All cranes have a lifting capacity that is based on the angle of the boom. The more vertical the boom, the more it can lift. With that in mind you select a crane based on the amount of weight being lifted and the angle the boom will have to have to reach the load. In some cases extra counter weights can be added to some crane to increase their lifting capacity. You should be using a contractor to supply the crane and the knowledge to provide the proper equipment and do the actual work safely.
Q: are parts availble for shop crane? Hydraulic ram plunger o rings has split....need part?
may have one, or try a tractor supply shop in your area. You can try matching the ring at an auto parts store that has balk parts behind the counter.
Q: ok so i have to us my phone so just give me instructions no links no youtube videos cause my phone cant support them and my phone may not be able to load some of the links
You are asking for a lot but I have seen you request this a number of times, so I will do it...a sucker born. 1. Valley fold the paper in half so it makes a triangle. With the long side held away from you, valley fold the triangle in half again. 2. Lift the top triangle and valley fold it so that its top point meets its bottom point. Unfold the crease you have just made. Put your fingers inside the top triangle, open it up, and flatten it so it forms a square. Turn the paper over and fold and flatten the remaining triangle in the same way. 3. Make sure that the open ends of the paper are pointing down. Valley fold the top layer of both sides in to meet the centre crease. You will now have a kite shape. 4. Valley fold the top point of the kite down and crease well. Unfold the crease you have just made. 5. Open the sides of the kite by unfolding the flaps you made in Step 3. Lift the top layer of the kite's bottom point up so the paper bends at the crease you made in Step 4. Push the outside edges of the paper in to meet the centre line. Then flatten the figure so that you have a long diamond shape. 6. Turn the figure over and fold a kite shape on the remaining side as in Step 3. Repeat Steps 4 and 5 on this side. You will now have a two-sided long diamond. The bottom half of the diamond is split in two. 7. Valley fold the top layer of both bottom edges in to meet in the middle. Turn the figure over and repeat on the other side. 8. To make the crane's neck and tail, valley fold each half of the bottom section out to the sides. Crease well. 9. Unfold the right crease you just made and make an inside reverse fold. Repeat this step on the left side. 10.To form the head, fold down the end of the neck. Unfold this crease and inside reverse fold the head. 11.Hold one of the crane's wings in each hand. Blow hard into the opening on the underside of the figure and gently separate your hands. You crane will puff up and be ready to hang.
Q: my class is supposed to start reading poems/short stories by Stephen Crane.why should i look forward to his work?
Well, you know he lived in the late 1800s, so you probably have an idea of what his poetry will sound like. Then you read some of it, and the effect is sort of like walking into what you think is going to be a prissy hair salon and being whacked over the head with a bunch of bananas wielded by a glow-in-the-dark green monkey from Jupiter. Crane's stuff is that weird. And I mean that in a good way.
Q: Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?
After this the crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on an approximately 40 foot mast that consists of two mast sections. The mobile crane then adds the counter weights. The mast which is a large triangulated lattice structure typically 10 feet square then rises from this firm foundation. This triangulated structure gives the mast the strength to remain upright. The tower crane rises to its maximum height by using one mast section at a time, the crew uses a top climber that fits between the slewing unit and the top of the mast. This is done by hanging a weight on the jib to balance the counter weight. The crew then detaches the slewing unit from the top of the mast, this is done by using large hydraulic rams in the top climber to push the slewing unit up to 20 feet. The crane is then used to lift another 20 foot mast section into the gap opened by the climbing frame. Once bolted in place the crane gains a height of 20 feet. This process is reversed once the building is finished and its time to dismantle the crane and as stated earlier a smaller crane is used to dismantle the tower crane except the mast which is dismantled by the crane itself
Q: Basically what it says on top. Also provide maybe a video to prove it.
I think of myself greater because of the fact the paper plane sort.....going with the breeze and letting it take me the place it is going to. additionally, cranes are no longer very severe-high quality once you get too close to to them and could attempt to %. your face off in case you verify out them humorous.
Q: how to make a magnetic crane on cheap price?
The whole crane or just the lifting device? Not easy to be cheap in either case - the crane because of safety concerns and the lifting head because it requires a lot of now high priced copper wire, well insulated, and a hefty electrical source with long cables to get the power to the head. Best (probably) to buy used if you want to save money.
Q: Is stature of the crane a Japanese, Chinese, or Okinawan form?
Found in kata from all 3 sources okinawan japanese and chinese .GANAKAKU KATA in shotokan CHINTO in okinawan kata and in FUKIEN CRANE STYLE for chinese. GANAKAKU means crane on a rock.
Q: Whenever a vista shot of London comes up, there are a ridiculous amount of cranes. What's up? Are they always building something?
Cranes are used in the construction of buildings. It is the Storks that bring the Babies
