2.After quick erection, it can start working normally within one hour.

 

3.Correctly-positioned mechanism kinematics spacing.
4.High precision and reliable load moment limiter and load lifting limiter.
5.Special system: wheelbarrow persist axis break
6.Two purpose: arm-brace fixing and orbit walking
7.Overall haulage bridge can be easily altered into a transport tow (10t)
8.35m height and could be used 30 degree higher up

 

9.Crane body locked automatically, crane jib docked automatically, pulley at jib point positioned automatically. There is no artificial high-altitude operation through the whole erection and dismantling process.

Q:What does tower crane jacking up mean?
First of all, the boom and trim balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.Jiangsu Zhendong port machinery manufacturing heavy port machinery is a professional manufacturer of mechanism
Q:how can we make a troubleshooting for tower crane control panel?
Generally tower cranes have their electrical panels at the ground floor. Troubleshooting in the tower crane is not different to any other electrical system. First check the power circuit healthiness--switches,fuses,contactors and then go for control circuit. The cranes have few additional interlocks for excessive forward movement, extra long travel etc. Just go through the drawing and u will get the problem solved
Q:How many stops are there in a tower crane? Where are they located in the tower cranes?
The hook has an upper limit on the windlassThe car has front and rear spacing on the trolley hoistSlewing is limited to the slewing gearAnd the torque limit is on the spireWeight limit
Q:Operation points of tower crane (tower crane)?
Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
Q:Falling crane killing everyone?
Probably some stress or fear is looming large in your subconscious mind. Scary dreams often occur when you have something that is stressing you. That is assuming you didn't read some book or watch some movie that brought it on, that is another possibility. Often we replay images we have in our heads from the day before. I don't think it is an omen or anything. So, be glad to say it was only a dream.
Q:1000 paper cranes a myth?
During my lifetime I have made, perhaps, a thousand origami boulders. Nothing magical came of it. I rather suspect that you'll find yourself using up 1000 sheets of paper and ending up with 1000 paper birds. Have a nice weekend.
Q:I have so many crane flies this spring. Why?
Crane FLIES not cranes. The winter crane fly has an abundant hatch--well, during early spring or late winter. In this they are just everywhere--this species just does this sort of thing. Typically crane flies are a rather rare sight, such as during the summer months, usually of an entirely different species. There's really not much to explain their abundance.
Q:Daddy longlegs/Crane Fly... Most venomous creature on earth?
This Site Might Help You. RE: Daddy longlegs/Crane Fly... Most venomous creature on earth? Where i live i get a damn lot of these come in my house.... I usually just leave them unless there are too many. This was before i was told that they are in fact one of the most venomous creatures on the planet. I laughed, but then was told the same by a friend. Im now Little worried about...
Q:why do we see cranes on a golf course during a tourmanent?
The cranes have the cameras for the panoramic views which are shown throughout the broadcast. There were instances in the past when they also held the camera men.
Q:Paper cranes... What do I do?
Okay - so if you can't string them from the ceiling - than what I would do is buy some round vases/globes, from Pier one or some place like that, and fill them with paper cranes, then set the bowls on your shelves/windowsill/desk/table or other flat surface. I've enclosed some examples below. You can also make a mobile by hanging something like a super strength hook with adhesive. 3M makes them (the same folks who created scotch tape). The adhesive does not damage walls and you can stick them to anything. They can bear up to 30 pounds of weight. Put a few on your ceiling or walls and hang your mobiles from them.
