45RCS20 Series Hoisting Mechanism

Introduction

Such production are independently developed and manufactured by our company based on mature technologies of French Potain Company with rated hoisting weight of 8t,10t,12t and 16t.Horizontal and vertical motor mounting types and different rope capacity are available for users. Such products adopt two winding 3-phase asynchronous motors and series excitation speed regulation circuit which realize interactive effects via gear assembly to constitute speed regulating system with features of wide range of speed regulation, high-speeding hoisting, low-speed positioning, stable speed change and high working efficiency. The mechanism adopts L-shap in overall layout and employs winding drum of Lebus grooves with large rope capacity, which can prevent disorder in case of multilayer winding of wirerope and satisfy wide use demands of high-rise building construction, hoisting of large equipment & construction member, etc.

Q:Is the pink paper crane used to represent Lulu?: C.C taught Nunally how to make those paper cranes. It's the symbol of love and hope, I think. It's the symbol of a dream that Lelouch was able to accomplish. And symbol of life. It has many meanings. It just depends on how you interpret it))))

Q:How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?: Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.

Q:can u have a small dog w/u when u are operating a crane?: I can't imagine any employer allowing that condition to exist. A crane operator's attention must be on the job at all times. If the dog were to do something unexpected at a critical time, the operator may be distracted and lose control of the load.

Q:Plus why the symbiot instead of bringing the dark side of the carrier brought the gay and jerk side?: 1) Something happened to the crane - it doesn't matter what - it was an excuse to bring out spiderman, What happened isn't important. It was a kind of malfunction anyway - NOTHING to do with any villians 2) Gay and jerk side? He wan't being gay, but because he was a jerk in the first place that is why he didn't really know how to dress up properly and being up himself means he doesn't recognise it - which by the way, was well scripted into the movie. It was a bit of a comic relief. The symbiot brought out the darker side of him but that doesn't mean it KNOWs to make him behave appropriately.

Q:National standards for tower cranes: Tower crane GB/T5031 - 2008 has been implemented since February 1, 2009.

The new standards are quite different from the previous standards, adding a lot of security related content, mainly embodied in the following 3 aspects: 1) the principle of different. Previously considered issues mainly consider the domestic tower crane industry technology status, appropriately reflect the advanced nature, and now is the requirements and international benchmarking, consider safety. 2) different forms of organization. The standard used in scientific research institutes, universities, factory assistant; the preparation unit including Research Institute, and the host plant, supporting enterprises, universities, inspection unit, there are relatively large units on behalf of (rental business), etc..

Q:What is the inspection certificate for tower cranes?: Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
