Product Description:



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:Burj Khalifa: How was the Crane Removed?
They used a climbing crane , and who said that the building has no roof? the crane parts can be dismantled on site and removed either by helicopters or using the construction lifts
Q:Method for operating tower crane
2.21, drivers must pass the escalator up and down, up and down the escalator, hand tools are prohibited items.2.22 do not drop any objects from tower cranes or defecate.2.23 winter in tower crane operating room heating, should be taken to prevent electric shock and fire measures.2.24 any tower crane with an elevator must comply with the instructions in the elevator manual. No overloading or violation of the operating procedures.2.25 multi machine operation, should avoid two or more than two tower cranes overlap in the radius of rotation. Special circumstances, need to overlap operations, must be safe distance between the vertical arm to ensure the safe distance and the lifting of materials, and have reliable safety measures approved by the competent technical leadership before construction.2.26 jib cranes in heavy lifting off the ground after lifting, rotating and walking three actions can be done at the same time, but the amplitude only alone, strictly with variable load. A crane that allows variable amplitude loading shall not vary at full load or near full load.2.27 lifting hoist is not installed in the rotating part of the crane, lifting operations may not continue in one direction continuous rotation.2.28 a crane with a mechanical torque limiter must adjust the tonnage indicator of the overload limit device according to the radius of gyration and the rated load at that radius.2.29 bend rail subgrade must comply with the provisions of the crane should turn on the outer rail surface of the sand, rail, rail and wings painted with grease. The counterweight box shall be turned to the direction of the outward turn. It is strictly prohibited to do lifting or turning on heavy roads.
Q:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
Q:why the new york cranes collapsed?
Gravity, that's basically why all things collapse. With cranes you also tend to have the issue of them being overloaded also but at the end of the day it's still gravity that's the enemy. There is some talk of a supporting strut having been damaged by a piece of falling metal and the crane toppling as a result of that but it's the first time I've ever come across a piece of lifting equipment, and that's what a crane is, reliant on just one component to keep it standing up. Always remember that gravity thing is out to get you.
Q:I need help getting back to crane in maplestory?
what? take the next exit
Q:what are the forces in a cantilever crane?
forces for cranes are dynamic , so u'll have repeated cycles of compression tension ( i assume it's a trussed crane). but generaly for a cantilever , the main forces are -ve Bending Moment +ve shear which changes the rft. bars position if dealing with R.Concrete for example
Q:What are the basic parameters of a tower crane?
The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...
Q:Cranes or storks?
Depends on where you live ? Stick to Ornamental Pheasants or Ducks,Storks and Cranes,need to be penned in at night because you will have to pinion them to prevent them flying. Try some Golden Pheasants for a try ,Lady Amherst are becoming a rare commodity and are quite expensive,if you have Foxes and Mink,then no matter what you get you will have problems these two predators.
Q:how do construction crews put up a crane?
They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.
Q:What association does Wing Chun have with Fujian White Crane (Tiger-crane) kung fu?
Fujian White Crane is not Hung Gar or Tiger Crane. Southern White Crane, or Gu Lou Kuen (Ancestor Fist) is the predecessor to Goju-ryu karate. Goju and GLK emphasize the sam jian ma, sanchin dachi, or three battles stance, and rootedness, body conditioning, and strong shoulders and arms. The power comes from the rooted base and strong arms. There are rumors that Wing Chun is derived from Ancestor Fist, but philosophically, technically, tactically, and strategically, the styles are extremely dissimilar except for the short range fighting. Wing Chun is also rumored to be created by Ng Mui or Wu Mei, the Buddhist Nun. But the resemblances between modern Wing Chun and styles named after the nun are few and superficial. Wu Mei emphasizes power generation in numerous ways and continuous attacks. Wing Chun emphasizes deflection and power generation by shifting the feet, and simultaneous attack and defense. Wu Mei also has a full suite of weapons, and Wing Chun only the pike and butterfly sabers. Wing Chun is a style created in the Shaolin Temple, but it is probably closest to Hsing-I Kuen or Hsing Yi Quan in training with their chi sao or sticky hands practice.
