Introduction:

Tower crane is used to lift, lower and horizontally move materials in construction and other industry. It has large lifting capacity and lifting height, wide moving range, and can rotate. It basically consists of base foundation, mast, slewing unit, working jib, counter jib, counterweight, hook, and operating cabin.


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.

Q:How big is the contactor lifting? How big is the car and how big is the turn?
How big is the lift? It depends on the size of the motor you use. 24KW motor, the choice is about 100A. 30KW uses 125-150A, 55KW, and 150-180A;Generally 40A contactor is used for turningCar selection of 25A on it.
Q:More than meters of tower cranes must be equipped with red barrier lights at the top
To see the land of tower crane or floating crane... Basically, however, tower cranes over 30 meters above the tower shall be equipped with red light on the top of the tower and jib.
Q:A 3000-lb wrecking ball hangs from a 40-ft cable of density 10 lb/ft attached to a crane. Calculate the work done if the crane lifts the ball from ground level to 40 ft in the air by drawing in the cable.
The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
Q:Jon and Paul are folding origami cranes. If Paul works alone he can fold 100 cranes in 5hours. together they can do the same job in 3 hours. how much time would it take for Jon to fold 100 cranes alone? Please show your work. :)
1/5 + 1/x = 1/3 == x = 15/2 = 7.5 h answer : 7.5 hours ++++++++++++++++++++
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:I just watched hunger games, and in the end Secana Crane was locked in a room with nightlocks, but why did they do that to him? what did he do to get killed?
The Capitol is a government that rules through absolute control. They're keeping the different areas under control through force, and everybody is too afraid of being killed to stand up to them. The Hunger Games are there to make people afraid of revolting and to give them some hope of one day becoming famous. Crane got killed because he allowed Katniss and Peeta to beat the game. The point of the Hunger Games is that there can only be one victor, but Katniss let them both live. By doing that, she showed that the Capitol couldn't control everyone absolutely, and they could beat the Capitol if they tried. Crane got killed because he let that happen. It also drives home to the reader how brutal Snow can be, and how willing to throw away a life he is.
Q:my yard is infested with crane flies. Help please.
It's impossible to think of an insect more harmless than a crane fly. Enjoy them.
Q:Is there a crane big enough to lift Hillary off the yoga matt when she has finished her yoga?
You wouldn't need a crane, all you'd need is a hershey's bar and she'd wattle off the yoga mat. Or, you can present her with facts about the destruction of her e-mail server, the fact that she allowed innocent people in Iraq and Syria to die, or the fact that she hit the reset button with Russia, and she'll RUN AWAY from the yoga mat.
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
As for the calculation method, the weight of a simple arm length * arm tip can not be used, because the nominal lifting torque of the tower crane is not calculated at the maximum amplitude.However, the maximum weight can be calculated by the maximum amplitude of the maximum weight, such as 5613 tower cranes, the maximum lifting capacity of 6 tons, while the maximum variable distance of 6 tons reached 15m, 60KN * 15m=800KN.m.The above is only my personal understanding of the tower crane, but I am not a professional construction machinery, the above calculations do not know whether it is reasonable, I hope to help you.
Q:i saw a PS3 in a claw crane game at Six Flags Over Georgia i wonder how you can win it. It is possible to win it... somehow. I thought that the strategy was to lift the prize that is closest to the hole. I almost won a Kinect that way. So are there any other strategies??? Don't say buy 1 or there isnt a way to win because there is.
It's impossible to win them if they are in a crane machine only gullible person will try to win a PS3 from a crane machine as it will not be strong enough to pick it up
