TC4708

TC4708tower crane is a new-style hoisting and transporting machine designed to meet the need of assembling high-level construction equipment. The product is an upper rotary self-lifting kind with horizontal jib, trolley amplitude. The length of the jib is 47m, rated maximum lifting capacity is 4t and rated maximum lifting moment is 400kN.m. The following is the main characteristics.

1. Wide applicability. The applicability is ranging from civil construction in small and medium cities, to high-rise, multi-layered civil construction in big cities. It can also be used in the construction of multi-layered industrial factories, in the slip-form construction of huge chimneys and silos and in goods loading in port or goods yard.

2. Easy to assemble and disassemble.

3. High speed, easy adjustment, stable operation and high efficiency. Low speed with heavy load and high speed with light load can be realized through lifting structure. Two kinds of speed of trolley can meet operational needs. Open stopper is equipped to slewing structure, enabling precise placement and easy assembly of crane.

4. Complete protective and reliable safety devices. The product is equipped with weight limit, moment limit, height limit, trolley limit and slewing limit to ensure normal operation. Besides rest platform, protective railings are also equipped.

5. Driver’s cabin is separately set. It is broad, bright, comfortable, safe and easy to operate.

Q:I am looking for guidance on determining the optimal design parameters for the design of an overhead travelling crane when considering a span of 60m and a lift requirement of 2500Tonnes. If not possible what would be the maximum lift for the same span: is the 60 is the traveling distance or the span? if it is the span then this no way can be achieved or found, also 2500 tons is not logic for a single lift, you need to verify the design requirements. Usually crane span is related to structural frame spans, the lift has to be a practical one, which ranges from 1 ton to a 250 tons which is again very rare, majority traveling cranes are from 1 ton to 25 tons

Q:What are the working mechanisms and safety devices of tower cranes?: About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism. A safety device: four limit: height limit, amplitude limit, slewing limit, travel limit; three insurance: luffing rope insurance, car insurance broken shaft, the hook to prevent falling insurance; two limit: torque limiter, weight limiter on these roughly.

Q:i am making a wired crane robot to pick and drop a wooden block of about 5*5*10cm dimension. I would like to know wat r the different possible lifting mechanisms by which i can lift the wooden block.Ideas other than the normal claw shaped lifters: There are different attachments that you can put on the end of your crane to pick up this block. You can make a set of forks (like a forklift) that would slide under the block (block would have to be elevated on a skid). You can pick up this block with a suction cup. You can also pick up the block by clamping the sides of the block by replicating a scissor type mechanism.

Q:Under what circumstances does a tower crane require third party testing?: New clothes, relocation or transformation should be examined by the quality and Technical Supervision Bureau

Q:Please help. I need real answers.: About Ichabod Crane, the school master, Washington Irving writes in A Legend of Sleepy Hollow: He was, in fact an odd mixture of small shrewdness and simple credultiy. His appetite for the marvellous, and his powers of digesting it, were equally extraordinary; and both had been increased by his residence in this spellbound region. Ichabod Crane digests Cotton Mather's (a Puritan preacher) History of New England Witchcraft, a book in which he firmly and most potently believes. He spends many hours reading Mather's work, and fluttered by his excited imagination he believes that he is struck with a witch's token at times. To drive away the evil spirits, he sings psalm tunes. Nevertheless, Crane still delights in the supernatural, so he spends winter evening with the old Dutch wives who exchange tales of ghosts and goblins around the fire. In turn, Ichabod entertains them with Mathers's reports on witchcraft, as well as predicting what the sounds in the winter air portend.

Q:What was the mekhane (crane) used for in Greek plays?To remove scenery between actsTo lift the king and his court to their viewing boxFor actors playing the godsIt was only used in building and tearing down the set: For actors playing the gods. The Greeks loved theatre, and just like today, there were cheap productions with little merit or wothiness for remembrance. In these cheaper plays, the creators would try to appeal to the people's religious convictions by having one of the gods (usually Zeus) descending from heaven to resolve the conflict and set things right. To present this in theatre form, the actor would be lowered down to stage on a crane in order to simulate the god descending from heaven. This became such a tired cliche in ancient Greece that the phrase Deus Ex Machina, which translates to God of the Machine, has come to mean An unexpected, artificial, or improbable character, device, or event introduced suddenly in a work of fiction or drama to resolve a situation or untangle a plot.

Q:What is the most likely reason that Crane never tells us the lieutenant's name in episode of war?: The Stephen Crane Society Stephen Crane did not have a middle name. Stephen Crane is buried in ...

Q:I have to build a hydralic system that can pick up a paper clip . the supplies you are allowed to use are 10 straws, 5 pipe cleaners, 1 yard of masking tape. 10 note cards. 2 syringes and tubing. 5 rubber bands. 8 popsicle sticks. 2 feet of string. 1 magnet. Please help.: build a basic crane out of your materials and thread the string to the magnet hold it on with tape secure opposite end of the string to the plunger on one syringe. and fix this syringe(syringe 1) to the frame of the crane. position the plungers of both syringes at mid point, and fill both with water, and fill your tubing with water. connect the needle ends of both syringes together with the tubing. pushing the plunger on syringe 2 will cause the plunger in syringe 1 to move out. pulling the plunger on syringe 2 will cause the plunger on syringe 1 to retract and can be used to lift the paperclip.
