Product Description:

Descriptions of our tower crane:

1, the topless tower crane reduce the dismounting requirements, lower weight, low mounting height, dismount each mast at a time in the air, save the labor cost, safety and fast.

2, it is suitable for crossover work of the cranes, without the tower cap and pull rod, the safety will be increased when there need the crossover work.

3, It is suitable for the special requirement about the height, such as airport nearby, tunnel, workshop ,and the construction site with high-tension cable.

4, It is suitable for the construction site that has the requirement about the crane boom, it can be used as internal climbing crane in the high-rise buildings, irregular roof or small areas.

5, It is very convenient for dismounting in the restricted construction site, dismount each crane boom at a time by manual.

6, The steel structure of crane boom has long using life and high safety standard.

7, The crane boom is good applicability, high-usage,the design of the topless tower crane boom is easy for realizing the serialization and standardization. Reduce the design and making cost.

8, Low design cost, short cycle, can much better satisfy the multiple demands of the customers.

Advantage of our tower crane:

1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.

2,It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation

3, boom stability is good, combination amplitude range.

4, suitable for height have special requirements occasions construction.

5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:What does "automatic tower crane" mean less than 100 tons per metre?: The problem is a bit ambiguous, 100 tons of rice is the lifting moment.

Q:So how does tower cranes and cranes used in constructions make use of mechanical advantage exerted from simple machines such as pulleys and levers?In other words, how does a crane use pulleys and levers?: a crane has a pulley in order to reduce the workload. Each time there is a loop of the pulley made the workload is reduced.

Q:I am currently an electrical apprentice but would like to become a crane operator. Something i have always wanted to become. I was wondering what the job market is for a tower crane operator vs a mobile crane operator? Also what is the salary comparison? Also how to get my foot into the door and become one. Thank you!: You have to be able to do simple trig to figure what your crane is capable of. You will have to become a member of the crane workers union. Someone may have to die to make a space for you. You may have to take jobs that are just fork lift qualified, if you are lucky, you might find work at seaports unloading cargo ships.You may have to work your way up through the ranks as a wrecking ball operator. The very lucky will make 50-60K +. The really good ones will make more only after many years.

Q:I read the book and thought of a theory... I think that the headless horseman is just and alter ego Brom Bones alter ego and he wanted to kill Brom Bones for his beloved Katrina Van Tassel... I want to hear your opinions and theories possibly involving what you think Katrina said to Ichabod during the party. That would be nice thank you.: I do think that Ichabod was murdered by either Brom or one of his friends. I can't imagine how the character Brom could have pulled it off without help. Although from a folklore standpoint, the story is loosely based off of the story of the Wild Hunt. The time of year in the story is right for the Wild Hunt to have been riding by, as well as the isolation of the town. In that case, Ichabod could have either joined in the hunt and become cursed as a rider himself, or been consumed by the various monsters that are said to ride with the King.

Q:are they for camera support: Yes Best of luck with it

Q:I need to draw an injured crane (the bird) with an arrow in its wing, lying on the ground...preferably with a splayed wing.How do I draw this? Sketches would help.Thanks.: Shoot a crane with an arrow and take a picture. Life drawing and technology mesh well.

Q:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane, if each were to unload the same ship alone. How long does it take for each crane to unload this ship?: I'm surprised by how difficult and convoluted the other answers are. They're also wrong. If two cranes are working together and one crane can, in fact, do the job in two hours, then it cannot possibly take longer than two hours with the help of another crane. That makes no sense just by simple reasoning. So the answer of 2 and 14 hours is not correct. Not even close, really. Here's the simple, neat, and correct approach using basic algebra with no assumptions necessary or made: If crane 1 can unload at a rate1/x per hour, then crane 2 can unload at 1/(x+12) per hour since it takes 12 hours longer. The two cranes combined, unload at 1/8 per hour, which must be faster than either one alone. Example: If I can eat a pie in 3 hours and you can eat a pie in 6 hours: 1/3 + 1/6 = 3/6 = 1/2, so together we can eat a pie in just 2 hours... less time than either one alone. Makes sense. Back to the cranes, then: 1/x + 1/(x+12) = 1/8 (2x+12) / (x^2 + 12x) = 1/8 16x + 96 = x^2 + 12x x^2 - 4x - 96 = 0 (x - 12) (x + 8) = 0 - x = 12 or -8 Since the rate cannot be -8, the answer is x = 12 Crane A can unload all by itself in 12 hours. Crane B can do it in 24 hours, and together they can do it in just 8 hours. Check: 1/12 + 1/24 = 3/24 = 1/8 Their combined rate is, indeed, 1/8 per hour!

Q:i just ordered a new JG 614 crane stock and do not know how to use the crane stock i would like to learn before it arrives can i have a link to a video or explanation please: Try reposting in the 'toys' or 'airsoft' section. This section is for men with real guns.

Q:Do self lifting tower cranes allow a small swing of the boom in jacking operation?: The upper working structure of the attached tower crane is connected with the jacking sleeve frame, and a jack jack is mounted on the top lifting jacket frame. The upper crossbeam of the jack is connected with the jacking frame, and the lower cross beam is provided with a movable claw, and the lower supporting point can fall on the step of the standard section of the tower body. During lifting, first trim jib and balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.

Q:i'm doing it for fun but i was wondering because my aunt had a baby that like 1 and the baby has cancer and i'm gonna try this to help her please don't be mean like the only thing you will get is sore hands and stuff is it true or is it a myth only answer if you did thid and i want to know what happened to you but anyway ill pray to god that everything will be ok with the baby: Doing anything that involved will put a tremendous amount of energy into the reason for which you are working. You could say a sentence a thousand times and make a miracle, and that's just praying. Intention + spiritual energy = real change the basis of prayer vigils and traditional magic. It's funny how it's actually the same thing. Embrace spiritual power!
