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: Please write in days, hours, weeks, etc.I need math help!!!!
- 13 years 8 months 2 hours 13 minutes 20 seconds
- Q: don't its wheel provide the same amount of friction?
- To make it harder for them to tip over.
- Q: what can lead tower crane to blank out?
- （1） tower crane has crack; （2）Brake block friction lining wear up to 50% ofRaw material thickness ; （3）Brake wheel surface wear reaches 5mm ~ 2mm （4）Spring has plastic deformation; （5）Lever system, air travelis more than about 10% of its rated trip
- Q: When the tower crane foundation is found, what should be discontinued?
- The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped
- Q: In Scottsdale AZ I have never noticed them before this year. They are on the walls all around our doors.
- cranes leave their habitat because the first reason was the climate , second its mating season and lastly scarcity of food in their habitat during winter .

- Q: What are the safety devices for the horizontal arm self lifting tower cranes?
- (3) the amplitude limiting device shall be equipped with a minimum amplitude limiter and a device for preventing the boom of the boom from rebounding after the luffing of the jib. The trolley must be equipped with a trolley switch and a terminal buffer. (4) rail clamping device and walking limit device; track type tower crane must be equipped with rail clamping device. A walking limit device shall be installed at the same time. (5) a crane with wind point at the root of the boom with a height of more than 50m shall be equipped with an anemometer at the top.
- Q: I was half way through this book and had to stop reading it because school got in the way. I'm back to reading it and I got to the part where Katniss made a noose and tied it around a dummy and showed it to the Gamemakers. And she wrote 'Seneca Crane'. I don't remember who that was. If it was even a person, I guess it was. But can you just explain who or what 'Seneca Crane' is and why Katniss would do that? Thanks.
- I think it's one of the gamemakers, but that's just a guess.
- Q: We had a very large tree removed from beside our house. The crane parked in the driveway and caused four very large depressions and crushed concrete.
- No. The driveway is NOT a covered structure. The standard homeowners policy specifically excludes driveways from coverage. But the contractor who brought the crane in, should be responsible for it.
