- Q: the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
- difficult question
- Q: OMG! a phoba of crane flys, and there are 5 on my celling right now!!! What do I do, will the move and fly around eventually? I can't kill them, they are out of my reach, and if they start moving, im runing the %^$ outta my house.Will they die by tommorow? or will they just hang there?
- You !!!!!!!!!!!!!!!! that made me jump, i hate spiders... But they do say they are good for keeping the flys down...Personally i use a spray or a fly swatter, the swatter is great because it gives them an electric shock and kills them straight away.
- Q: What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
- 2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device 3, tower crane, such as lifting weight limiter, amplitude limiter, height limiter and load torque limiter limiting device, and travel limit switchestower lights wind instrument, wind clip rail device ladders athletic supporter circlewalkways and railings. The driver's cab is comfortable, easy to operate, with good vision and perfect communication facilities.
- Q: crane:300t lift 100t pad sizes:4.5x2 mtrs.ground bearing capacity required?
- This depends on the angle of the lift and the distance away from centre of the crane. With the lift at tipping range all 400t will be distributed along the outer half of the pad or on the extreme legs. Rule of thumb is all the load is placed under the one pad. so one pad is 9 sq metres and the load is 400 tonnes so the bearing capacity must exceeds 400/9 tonnes per square metre. 44.44444t/m^2
- Q: the cable of Crane I creates and angle of 30 degree angle from the horizontal and the cable of Crane II creates an angle of 45 degrees from the horizontal.-draw a figure that gives a visual representation of the problem-write a vector to represent the tension on the cable of Crane I-write a vector to represent the tension on the cable of Crane II-write a vector to represent the 20000 lb cargo container being lifted -calculate the tension on both cables. Justify your answer.....please help me!!! thank you!!!!:)
- All I can say is.. Big crane make big thing go up.
- Q: I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?
- First, okorder /. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.
- Q: Operation points of tower crane (tower crane)?
- Safe use requires the use of tower crane, issued by the state competent authorities shall abide by the rules and regulations, but also comply with the relevant provisions in the manual: the crane working environment temperature is -20~40 degrees Celsius, the maximum working pressure is 205N/m2, when should stop using the winds of more than 6 level; the same construction site to install more than two sets of tower crane when should pay attention to the location of each tower, take the elevation of different operations, in order to avoid the tower crane jib, balance arm collision accidents; safety device of tower crane, luffing and slewing height, mass and moment limiter, the last two more important, if the two is not detected qualified, will be regarded as the unqualified, because it plays a role to ensure the safety and prevent the tilting of the tower crane. As a construction site, the tower crane torque limiter failure or to replace the operating personnel mistakenly believe that daily only hanging 800-1000kg materials, not what the risk, the results in a process of lifting materials, because of the construction site is narrow, hanging by the operator sight blocked, hanging objects hanging on building the steel frame, caused by tower crane shaking, was the occurrence of major accidents, thanks to the ground work riggers promptly notify the operator immediately stop to avoid rollover accident of tower crane appeared. It is obvious that all safety devices on the tower crane are essential and must be checked regularly to ensure that all the safety devices are in good condition, sensitive and reliable.
- Q: I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks
- They started to go by the wayside in the early 80's around here, though they were still in use until technology caught up and they could manufacture a 200 ton capacity crane for use on the highways. They had Hi-rail equipment and could get to the scene of a derailment much quicker than the old steam derricks. Near the end, I know there were at least 5 still operating, but the problem was, there were only two guys on the system that could run one of the things. Steam is the key word. We're all used to seeing crane operators running the machine from their little cab and moving the levers that control the hydraulics. But, it was amazing to see a guy run one of the Bucyrus Erie 200 ton derricks. All the functions were controlled by various valves that were scattered around the operators position, and it was like watching some kind of choreography; ballet, even. The sights, smells and sounds of the thing in action were no less eye catching than watching the operator himself.
- Q: Does anyone have any info on John B. Crane?
- Do you mean the Lecturer John B. Crane of the Redpath Chautauqua Collection? Thats the only one I know.
- Q: cover up? I know he was into pornography and who knows what else!
- Crane had just spurned his long-time friend John Carpenter. Carpenter was tried for the murder based on blood found in a car he rented, however he was acquitted as a murder weapon could not be found. The case remains officially unsolved.
