Characteristics of QTZ80-8T Self-erecting Tower Crane

1) QTZ80 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 180m.

3) 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.

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.

4) The crane has complete set 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.

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

Q: i am making a wired crane robot to pick and drop a wooden block of about 5*5*10cm dimension. I would like to know wat r the different possible lifting mechanisms by which i can lift the wooden block.Ideas other than the normal claw shaped lifters
There are different attachments that you can put on the end of your crane to pick up this block. You can make a set of forks (like a forklift) that would slide under the block (block would have to be elevated on a skid). You can pick up this block with a suction cup. You can also pick up the block by clamping the sides of the block by replicating a scissor type mechanism.
Q: science project
hydraulic
Q: I know you need to put current around the magnet (or certain type of metal) in order to attract but is it possible to use as pushing an object away. if there is please tell me how!
To push an object away, you need equipment that is low to the ground when it applies the force. Bulldozers are designed to push objects. Electromagentic cranes are designed to deal with vertical forces, so they are used to lift and drop metal objects. They use electricity to flow through coils wrapped around a metal core to generate a strong magnetic field. Trying to use them to push things could cause a crane to tip over since they are not designed to deal with horizontal forces. Even if you could get the electromagnet wired to repel metal objects, when you bring the electromagnet near the object, it would repel away in an unwieldy manner because of friction and interference with the ground. And trying to direct a large electromagnet at the end of a long chain would be difficult.
Q: do they get the concrete blocks up that hang at the end? Do they use another type of crane to assemble them?
Tower cranes assembly starts with the foundation of the crane with lot concrete blocks for fixing, then they fix the first bottom part of the crane then they fix the boom with the counter weights, when they want to extend the height, they fix a jack up machine which lift up the boom and then insert a vertical piece and so on till they reach the required height. During the first installation they use a small mobile crane and then after the crane it self lift and fix the pieces
Q: You see cranes on the floor which rise about 50 metres, but sometimes, when building high sky scrapers, I see cranes on the 70th floor or the 80th floor. How do they put the the crane so high up there when it can only go up high around 60-70 metres?
The cranes are built in the elevator shafts and moved up as needed during work progress.
Q: Construction tower crane operator certificate expires, how to verify?
Two, training contentThe crane safety regulations and operation management; classification and main parameters of the crane; the structure and the working principle and the safety protection device of lifting up; the installation and removal of heavy machinery; the whole debugging and acceptance of heavy machinery; the operational and command signal of lifting and repair; and maintenance of heavy machinery.Three, training hours and full-time training arrangement: 5 days, annual training enrollment.Four, training fees450 yuan / person, including registration fees, training fees, books, information, assessment, assessment fees, accommodation, self-care.Five, training certificationStudents complete the prescribed courses, through the examination, after passing the examination by the Municipal Construction Commission issued a number printed and stamped with the "Chongqing City Construction Management Committee of" legal. "Chongqing construction tower crane operator qualification certificate".
Q: a/ Calculate the lift workb/ What is the power used by the crane when the efficiency is 60%? (Can you explain for me what efficiency means)c/ What will the kinetic energy of the load be when it hits the ground, if it falls from the height 8.5 meters, g=9.81 m/s^2Thank you.
The work done (W)= Force*Distance. Force is 9.81*3000kg. So W = 9.81*3000*8.5 = 250,155 J Power (P)= Work(W)/Time(t) = 250,155/15 = 16,677 W 60% efficiency means that the lift is only using 60% of its maximum amount of power output. So to find 100% (lets call it x) of the crane's efficiency, consider the following: x * 0.6 = 16,677 x = 16,677 / 0.6 = 27,795 W Total mechanical energy in a system remains constant, so the kinetic energy the moment it hits the ground equals the potential energy when it is still hanging in the air. Potential energy = mgh = 3000x9.81x8.5 = 250,155 J You know this is correct, because it is the same amount of work the crane performed on the object to lift it.
Q: Does a crane have a pulley?AND....Is an axe a wedge?THANX CUZ I DONT KNOW WHAT IM DOING, AND OMG IM SO GOING TO FAIL MY TEST BECAUSE IM SO DUMB.
Yes, a crane has a pulley in order to reduce the workload. Each time there is a loop of the pulley made the workload is reduced.
Q: what does a paper crane represent/symbolize?
to get well. if someone you know is sick the Japanese say a thousands cranes will make them well.
Q: I am writing a story for school about working in Dubai as a crane driver but I need to know what the purpose of a Crane driver is, how much they get payed and stuff like that. And if you could tell me how a crane driver can get admission in the first place, it would be really great. Thanx. And btw, this story is for Geography.Thank you. :)
i am not a crane driver myself , but into this field of construction . get a licence as driver from authority just as a car driver. know how to drive the crane ad a driver know how to operate a crane as a operator. know the performance of the crane and its limits. the salary can vary depending on the type of crane and its special features. but not in the high end grade for sure unless its a very specialised crane operation. u can ask any thing more .
