Product Description:

70RCS30 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:how much does a whooping crane eat per day?
To figure out exactly how much they eat you would have to know the exact weight of the bird, the calories in the food, and the condition of the bird. Which is a very long way of saying that I don't know the answer to your question, but there is a mathematical way to figure it out if you are really interested.
Q:why do whooping crane migrate?
It is freezing cold in the upper Midwest during the winter. Whooping cranes simply cannot find any food, even if they can endure the cold. During the summer, the upper Midwest has longer daylight hours and slightly cooler temperatures. than their wintering grounds in Florida. The longer hours allow them and their young more time to gather food. Reproduction is very taxing on the female body, even if it is just laying eggs. The young need the extra time and nutrition to grow quickly into adult sized birds. Small birds are more vulnerable to predators.
Q:Is the working load of a crane the maximum weight it is able to lift?
generally the safe working load (SWL) is the max weight a crane can lift in regular operation . but for testing purpose the crane may be loaded more (1.5 times SWL or 2.00 times swl) further it depends on application of the crane. The reason being if you test the crane for higher values, it means it is safe to use within the SWL But the higher value must not cross beyond structure design load
Q:How do they erect HUGE cranes without a crane?
The really huge cranes with the boom that goes straight out at a right angle to the upright section (which goes straight up) is called a tower crane. They're assembled by using a jack assembly at the bottom, so that more sections are stuck in at the ground level.
Q:What is YOUR take on Louis Crane's idea of meduso-anthropic principle?
Well, weak- anthropic beats the hell out of strong- anthropic. One cannot, in good conscience, postulate God from the improbability of a good primordial soup kitchen, when beating the odds is the prerequisite for anything evolving sufficiently to be amazed. Life, however, plays hell with probability, because it’s possible for an improbably complex thing to create as many improbably complex things as energy allows. Introduce evolution, crank out a tool user, it gets worse. One dedicated farmer can create a vast and profoundly improbable flourishing of life. Now if we move out into the universe and find a vast and improbable flourishing, we will have cause to suspect the existence of cosmic farmers. This especially because it appears we are evolving towards that state ourselves. Dressing up this concept in pseudo science though, strikes me as a bit pretentious. Which is my take on Louis Crane's idea of meduso-anthropic principle
Q:Are tower cranes the same as tower cranes?
Tomato, you tomato, potatoes, you potatoTalent exchange of tower crane and tower crane
Q:Help with crane fly larvae in my kitchen?
probably not larva of crane fly...they live in the soil outside. Describe or post a pic what you have
Q:what is crane rigging?
Wire rope is twisted line made of stainless, or high tensile steel. Rigging refers to the slings, or chains that attach the load to the lift hook. Rigging also refers to the act of attaching a load to a load handling device, such as a crane.
Q:how many days does it take to make 1000 paper cranes?
It depends on how many people are making them. Depending on skill it takes about 2-5 minutes to make a crane. If you dedicate 5 hours a day that makes 7-50 days if one person is making them. Cranes are often made for memorial. It is a Japanese tradition, especially for Hiroshima. You make 1000 cranes as a memorial for the lost lives. She should definitely get her friends to help.
Q:does wing chun and karate come from the same white crane style of wushu/kung fu?
The correct answer is given by Daoshi.
