Product Description:

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:

  1. Hoisting arm can reach 65m, which largely increases covering area, and its working scope can satisfy constructions of more than two buildings simultaneously.

  2. 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.

  1. 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.

  2. 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.

  1. 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.

  1. 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.

  2. Driving room is set separately on side with good field of vision and large working space, which create better working environment for operator.

  3. 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.
More than 2,800 employees and a countrywide production, sale and after service network ensures strategic advantage on production and design of products of Shandong Huaxia Group.
Products of Shandong Huaixa Group are the best choice for selecting construction equipments.

Q:Can someone explain the support cables on a tower crane?
its called wire rope. Cables are for electricity and TV.
Q:Maggie: Girl of the Streets by Stephen Crane?
hah ha i'm in your class too :) This project sucks... and I still haven't done it! I have to tonight..
Q:how to get rid of crane flies?
It's impossible to think of an insect more harmless than a crane fly. Enjoy them.
Q:when do i start bernie cranes missions gta 4?
You have to have progress enough to be in Algonquin (the second island) and yo have to complete the Hostile Negotiation and No Way on the Subway missions before you encounter Bernie and are able to take mission from him.
Q:When do crane flies leave?
Crane flies tend to live in wooded areas and open fields, but they can live nearly anywhere, including snowy northern climates and desert lands. In order for their eggs to hatch and larvae to grow into adults, they require either water or damp, decaying material in which to lay their eggs, depending on the species. Crane fly larvae and pupae can be found in damp sod or compost piles, or under the decomposing leaves on the banks of rivers, streams, ponds or lakes. Crane fly larvae and pupae feed on decomposing material, grass and the roots of many plants. This makes them a beneficial insect, as they assist in the cycle of decomposition. Once they emerge in late winter or early spring as adults, after maturing over the winter, their primary purpose is to mate and lay eggs.
Q:We have a whooping crane living in the bayou.?
Want to help? Don’t feed them, which draws them deeper into dangerous urban areas. And try to keep reflective surfaces covered. Following these tips could keep these majestic citizens a little safer. In 2002, the Florida Fish and Wildlife Conservation Commission made it illegal to feed sandhill cranes. Why Is Feeding Cranes A Bad Idea? Cranes fed by humans can become aggressive toward people. In several instances, children have been attacked by cranes. Cranes fed by humans also have been known to damage window screens and do other property damage. This behavior is probably a response of the birds to seeing their reflection, bringing out a territorial defense behavior (scratching at windows or shiny automobiles). Cranes also are more likely to tangle in human garbage in areas populated by people. Cranes attracted to people's yards for feed are put at risk as they walk across roads. Many sandhill cranes are killed each year on Florida roads. Cranes are also more likely to crash into power lines in urban areas where such aerial hazards are concentrated. Attracting cranes to urban areas increases the threat of predation (especially to young cranes) by dogs or cats. Further, the cranes' diets, which normally are quite diverse, are disrupted when they eat one food item (such as corn), consistently. Heavy pesticide use in urban lawns also is of concern. Young sandhill cranes have died from pesticide poisoning. It's Never a Good Idea to Feed Wildlife People inadvertently put cranes in harms way when they attract these birds with feed. Florida sandhill cranes have an abundance of natural foods (insects and small animals) and they do not need handouts from humans. There are many reasons why cranes should not be intentionally fed by humans, so I hope this gives you a few you can communicate to these well-intentioned people. The bottom line message: For the good of the cranes, please do not feed them.
Q:can anyone give me some info on how to become a crane operator?
I agree. There are schools (USA) that teach this kind of thing. You attend, receive a diploma attesting to your success then you can approach prospective employers that hire people with these skills. I wish you the best. :)
Q:Stephen Crane and Willa Cather (talk about your odd couples) met briefly. He died shortly after at 29, I think
Definitely....... I guess since my mother died at an early age, I keep expecting it will happen to me as well. I don't think I react like Stephen Crane though..... I think instead of writing it all down quickly for people to read, i tell people everything and I fear in that way, whatever legacy I have to pass on will never be remembered. Time passes so quickly. I can't believe my daughter will be going to high school when I just remember walking her into kindergarten the other day. Is time my enemy? Not so much my enemy...... but a reminder of sooooooo much I need to do and want to do. A signal. At least I made it longer than 29. Let's hope I have a whole lot longer...... but seriously...... someone has GOT to make me write it all down!!!
Q:Will Homeowners Insurance cover severe damage to driveway caused by crane?
It all depends on the terms of your policy. Since we don't have the ability to read your policy - we don't know. Your best bet is to ask your agent. Or you can file a claim and let the claims department inspect the damage and determine if it's covered or not.
Q:how did charles darwin influence stephen cranes writing?
Influenced by Darwin’s Theory of Evolution, Crane believed that people’s actions were determined by environmental factors rather than by conscious choices on their part. He believed also that conflict was the crucible in which human development occurred, and thus was attracted to the violent and seamy aspects of human experience.
