1. Brief Introduction
QTZ160 Tower Crane is a new type of large tower crane for construction developed through adopting technology by Shandong Huaxia Group in 2000. During designing, general operations like limited meta count of steel structure parts, parameter optimization of entire crane, stability check of entire crane and choice of each mechanism, etc. are completed with computerized tower crane design platform, which has reached international leading level.
Max. hoisting moment of QTZ160 (6516) Tower Crane is 1940kn/m, and each index of performance occupies leading position among domestic products of the same grade. Its advantages are as follows:
Hoisting arm can reach 65m, which largely increases covering area, and its working scope can satisfy constructions of more than two buildings simultaneously.
It has many working modes with largest application range.
Groundwork is poured on the ground without under frame, and tower crane is fixed directly on the groundwork. This method makes tower crane spare groundwork section and crossing girder, and separate working height of tower crane is 46.2m under such condition.
If construction object is high, tower crane can adopt attaching mode, and hoisting height can reach 161-200m. If it is required to be higher under special conditions, please contact our company.
No matter which kind of mode is adopted, hoisting arm has lengths of 55m, 60m and 65m, which can be chosen according to different objects.
It adopts hydraulic hoisting system to increase or reduce standard sections, which makes height of tower crane rise or fall according to height of construction to adapt construction of different buildings.
Working speed is high, timing performance is good, and working efficiency is high.
Hoisting mechanism adopts double speed double pulley winding motor to realize low speed on heavy load and high speed on light load, and max. speed can reach 100m/minute. Start and brake are steady, impact is small, and operation is convenient. Swing mechanism adopts domestically advanced frequency conversion timing project, which makes start and brake become steady and reliable.
Horizontal Arm Frame and Trolley Radius
The tower crane adopts horizontal arm frame, load is hung in hoisting trolley, and radius is realized through horizontal movement of trolley on arm frame. Compared with luffing jib tower crane, working is steady, installation is convenient, and radius application is wide, which can make hoisting performance be fully exerted, enlarge storing range of construction materials, and make disposal of general construction ichnography be convenient.
Safety devices are complete, and there are brakes fixed in each mechanism, which can ensure working safety. There are safety protecting devices like hoisting height restrictor, trolley radius restrictor, moment restrictor, hoisting weight restrictor and swing restrictor, etc. fixed in tower crane.
Driving room is set separately on side with good field of vision and large working space, which create better working environment for operator.
Operation is convenient, and maintaining is simple.
Electric control system adopts domestically advanced PLC control with automatic malfunction judgment, overload and over moment safety chain protection, motor overtime protection, program controller of famous Japan Mitsubishi Company, transducer of Japan Yaskawa Company, relay of OMR Company and contactors manufactured through introducing technology of TE Company, which makes its reliability be much higher than general electric control systems. It is safe and reliable with less malfunctions.
There is no central collector to avoid disadvantages of short circuit and creepage because of damp and make entrance and exit of driver be easy.

- Q:which crane makes only one Life Partner ?
- um---one of them queer cranes? ha HA! cause only them gays use that term, life partner! am i right?
- Q:For anyone who has read/studied Stephen Crane - do you know of any connecting theme within his most famous short stories (the open boat, the blue hotel, the bride comes to yellow sky, the monster)?I was think naturalism b/c it is so prevalent in the open boat but is really the only short story naturalism is in
- sorry, i haven't read any Crane short stories, but i'm a HUGE fan of his poetry. it's some of the most bleak, raw, yet honest poetry i've ever read.
- Q:how to build a crane using:woodelasticsgluescrews/boltsbottlessyringesnailsplastictin canand rubber tubingplease be detailed,thanks! :)
- Carefully. okorder has kit numbers and downloadable instructions for many Lego cranes. You might be able to find some of them on OKorder. You may not need to actually build the Lego crane. Instead, look at the model, determine the major pieces (wheels, turntable, arm, etc.). Then, look at your bundle of pieces and make something with the same function.
- Q:Crane lifts a 600-kg bin with an initial acceleration of 2 m/s^2. Determine the force in each of the supporting cables due to this motion.?
- F = ma Assume the crate is uniformly loaded, both cables will carry the same force F(AB)(4/5) = (600/2)(9.8 + 2) F(AB)(4/5) = 3540 F(AB) = 4425 N F(BC) = 4425 N F(B-Crane) = 600(9.8 + 2) F(B-Crane) = 7080 N As a form of exchange, please remember to vote a Best Answer from among your results. This is not the same as like or thumbs up which are also nice and do boost points, but only after asker awards initial points with their vote.
- Q:Is the working load of a crane the maximum weight it is able to lift?
- Good long answer already given. Adding only that working load is for normal usage. A crane with an angled boom may be able to lift a higher load with a shorter boom (less with very long) or if the boom is kept at a higher angle so load is closer to base. This will be given in the detailed specs.
- Q:How often should the crane be inspected regularly?
- Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.
- Q:sun/rising/etcBQ: how often are your winnings
- i'm very bad at those machines..... be it the crane or any other kind, i just failed it again and again (kind of reminded me of squidward's failure to beat spongebob) well, i never had the talent to be the crane..... always failed even at getting the animals, it's so hard to pick them up! oh well~~ scorpio sun and rising
- Q:What other actress of the 1960s who could have done the role of Marion Crane in Psycho,in place of Janet Leigh and give result too?I think she perfect.
- Believe it or not? Alfred Hitchcock had thought Vera Miles would have been good in that role. He had one of his mini-crushes on Vera, and had planned to make her a superstar. However, he lost patience when Vera decided to enjoy her married life and have babies. Vera had no burning desire to become a superstar, and was happy with the work she was doing. She was also very smart in another way. She said that those parts worked out well for the blonde, sexy women that played them, but that just wasn't her look or her approach to acting. Vera Miles was in the movie Psycho, but she played the part of Marion Crane's sister. I've always thought that Janet Leigh was perfect in that role. She was so beautiful and unbelievably sexy that when she was on the screen? You couldn't stop watching her. Her ample bosom was an attention-getter all by itself. No offense to Janet Leigh, but I don't know if anyone cared if she could act or not! However, she did a fine job in Psycho.
- Q:I need to go to a tower crane school inside Las Vegas, where do i go? At least inside Nevada. Not Arizona or Utah or California.
- check with the International Union of Operating Engineers. I know that in the past, they provided the training, and past the general operators certification, there is a Crane certification, and possibly also a Tower Crane endorsement.
- Q:When the earthquake happened, the children wanted to know what they could do to inform other students and raise awareness for the people in Japan. So, we decided to do a show on the earthquake, and to also making the cranes, the origami cranes.thank you! a foreigner. （detail）
- I personally would write it as... So, we decided to do a show on the earthquake and to make origami cranes. However, for proper English grammar, your idea of saying to also make the cranes is correct for an addition with and. The sentence fragment ... and to also making the cranes... would not work because also is a interrupter to show continuation and is not a verb. To make is an infinitive so adding also would not allow the conjugation of the infinitive due to the rule that a verb cannot follow a verb unless if the second verb is in an infinitive form. And is never used with commas unless there are items in series such as ducks, chickens, and hens. And is not correct after a comma unless if there are items in series. In addition, the items in series rule can change slightly if there is a description with the items or a sentence fragment such as with the sentence... There are several large hens with an egg; a few with large wings; and a few with a large pile of food. In this situation a semicolon(;) is used to help people know that it is a series with a group of sentence fragments. If you need help contact me or find help with items in series, types of sentences, sentence fragments, and sentence interrupters. I am learning to speak Spanish so I am willing to help anyone with English because I know how difficult it can be to learn English.
