Q:Is it difficult to test tower cranes?
See the ability of individuals, the first ticket 650 yuan graduation card ID card (copy) medical certificate according to 3 inch 3 days learning theory exam two days of practice examination through 15 days notice thank you hope to adopt licensing
Q:How did the tower crane rise on the construction site? Fifteen
With a bar of steel, each layer has about 10 or more bars of steel. When the building rises, add a few more bars to the top floor, plus a few layers. It uses the stability principle of the triangle to keep the tower crane from tilting, and it also needs to pull some cables around to keep it balanced, just like a country pole.
Q:The role of slewing limiter in tower cranes is limited
The function of the rotary limiter is to restrict the large arm to stop at a certain setting. Protect from turning to dangerous range so as to avoid collision and other dangerous accidents!The function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
Q:What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
Q:Under what circumstances does a tower crane require third party testing?
New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
How to choose tower crane in engineering:1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
Q:What are the safety devices in a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.
Q:What does a track type tower crane look like? In that case, use?
With a trolley, it can move in a straight lineSuitable for short range movement
Q:In order to ensure the stability of tower cranes, generally along the height of the tower and building a number of meters attached
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
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
