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: How come you never see cranes being transported from one site to another?
- Many are too large to be transported whole, and are assembled on-site (or even build for a single on-site use).
- Q: Who do you think would win in a battle between Roger Thorpe and Alistair Crane?
- I know soaps are notorious for bringing back dead people but Roger Thorpe died on Guiding Light and of course more than once! =)
- Q: All types of jack up cranes. How is the maximum lifting torque converted?
- The moment of the tower crane is set up by the factory, and can not be changed. How do you want to convert it?If the nominal torque is converted to kn tons, 1 tons is equal to 9.8 kn.
- Q: Are there influence about Microwave and electromagnetic waves on the tower crane?
- if the spread is just in the microwave communications channel or radio transmitting antenna in the vicinity, will be subjected to microwave and high-frequency electromagnetic waves Interference, even if it is in all the tower crane hook when the closing power is outage
- Q: what is that max torque it can with stand when the max laod it can handle is 811 N?i can NOT get this question, its driving me crazy!HELP????? thank you
- I don't know if this is a question you got out of a book, or something you are trying to apply on a jobsite, but I would hate to see you try and use this approach with expensive equipment and innocent lives in the balance. Learn to use the crane charts. They account for many factors, including the weight of the boom, the tipping moment, the strength of the ropes, the engine's power, and the structural integrity of the boom.
- Q: I herd that there was some sort of legend that if you make a certain # of paper cranes you get a wish! Do you believe this to be true? Do you have to make 100 cranes or 1000 cranes?
- It sort of depends, maybe. And the legend says that it is indeed and unfortuantely 1,000 cranes. It also says you have to make all of these within a year, and it is a DIY project
- Q: When you're training to work in construction, do you need to do a seperate course or qualification in order to be able to operate a crane? Or are all construction workers taught it in training?
- Of course you need specialised training! Crane operators have to sit several courses in safe crane operations. Crane operators tend to just work cranes and not help with general building work as they earn more money and it is only cost effective to have them on site when they are actually needing to use the crane.
- Q: Okay Answers community, I need your help. I recently received a thousand paper cranes for my birthday and I want to know, what's the best way to hang them up (like on fishing line etc.)? Also, at the moment I think I'd like to hang them up in my bedroom, in interesting patterns. Any suggestions for how to arrange the cranes, or other ideas for what to do with a thousand paper cranes? Just remember, I'd like to keep the lot!
- use all of them to create one big one (assuming they're all similar)
- Q: which is crane lift planning software free to download?
- I okorder /
- Q: Does a crane have a pulley?AND....Is an axe a wedge?THANX CUZ I DONT KNOW WHAT IM DOING, AND OMG IM SO GOING TO FAIL MY TEST BECAUSE IM SO DUMB.
- Of course cranes have pulleys. If you know how they work it should be clear. Why else do you think there are two, or more (depending on the crane), ropes attached to their hook. Every rope added, except for the first, halves the weight of the object you want to lift. If you have two ropes and an object is 5 tones, the crane will only need the power to lift 2,5 tonnes. If it has six ropes it even only need the power to lift one tonne. And an axe is a wedge, logically. In fact, every tool with a blade is more or less a wedge. After all the wedge is the principal of a blade's function.
