Introduction:
Tower Crane is a machinery used for vertical lifting and horizontal delivering of building materials and any other heavy items during construction process. It can lift and lay down, horizontally shift, and rotate, so the working range is very large. The whole body can be fixed or movable.
Features:
1. It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
2. The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
3. The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
4. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.
5. Provide stepless speed regulation. Outstanding in working efficiency, operating stability and reliability,
6. This Tower Crane equipped with hydraulic lifting and connecting. This Tower Crane' s height can accordign to the actual height of the building and at the same time unchange the lifting capacity.
7. LVF: Frequency control, variable speed, smoothness and high stability, non-striking.
8. SM: Three-speed change pole motor, simple in structure, economical ,fitting.
Specifications:
- Q: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
- Q: In the U.S. please and tell me where and how you got the number.Thanks!!!
- There are so many overhead cranes in operation today in the US and around the world. They could be numbering in tens of thousands in industries and other operations. An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a goliath crane (UK, BS 466). Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors. Have a pleasant day.
- Q: would a tower crane be a first class, second class, or third class?
- The crane is balanced, with a fulcum somewhere between the ends. On one end, you have counter weight sometimes can be moved. On the end, you usually have the crane part, which can be trolleyed from the end toward the fulcum. If my memory serves me. a wheel barrow is a type 2, because the fulcum is on the end and the load is toward the middle. So this leaves you with a type 1 or 3. Try searching using the key word group lever type fulcum and I'll bet you get your answer.
- 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 is the present status of large Boom Tower Crane?
- Large boom crane arm depicts one and another new history. New York's World Trade Center towers is the skyscraper that is the highest and has the most floor in New York City .Its main building is steel and concrete composite structures,using steel 78 thousand tons.The Building started in 1966 and lasted seven years, with 110 layers, 411 meter in height as a giant skyscraper it is writed in history.

- Q: i want to go to school and learn to operate over head cranes
- No. they can't chew human beings. The lengthy pointy bit on the lower back isn't a sting both. it truly is an ovipositor, designed to allow the Crane fly to position her eggs in the soil. The eggs hatch out into leather-depending Jackets, gray grubs who devour the roots of grass. once you spot starlings and different birds on a backyard poking bout into the floor, it truly is what they're searching for, effective tasty leather-depending Jackets. leather-depending Jackets make the grass of a backyard pass yellow, and die. they're pests, notwithstanding the Crane fly is purely tense even as it comes interior.
- Q: i saw a huge one look liked it had a stinger to those hurt u?
- Could you speak in better English please?
- Q: Hey, can someone let me know some more about the support cable on the top of most cranes. Eg. material, what different types are out there etc. Thanks
- its called wire rope. Cables are for electricity and TV.
- Q: My Sister gave me a Russian Lacquer box with two flying cranes on it. There is supposed to be a story behind the cranes, but I can't find it online. Does anyone know where I can find this, or happen to know what the story is?
- Cranes are believed to bring good luck to people. So you are double lucky in this case; or perhaps even triple lucky since you have a thoughtful sister who have you such a lovely gift. Russian lacquer is magnificent. Nothing like it in the world.
- Q: What measures should be taken to make tower cranes stable?
- The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3 times of the same structure light steel wire rope (laboratory comparable conditions), not easy to wear and corrosion is not easy to cause the service life of wire rope large amplitude extension. Manganese phosphating is wear resistant phosphating, which can solve the wear problem in the use of wire rope and improve the corrosion resistance. It is for reference only
