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:Two cranes lifting at the same time .One has twice as much power explain this difference?
You suggested they are lifting comparable metallic beams. we do no longer be responsive to if the cranes are comparable of their overall performance. Are they the two lifting the load in an analogous way? would be one is shifting it vertically against gravity and yet another one is shifting it horizontally. The motor performance and the operator studies would be diverse. using and coasting would reason substantial adjustments.
Q:Explain how the idea of a counterweight used in cranes or in stand up basketball hoops relates to the concept of torque and equilibrium?
Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left). If you find this helpful, please award Best Answer!
Q:What do you know about Cranes (not the construction equipment, or the paper, the birds!)?
The oldest living crane is Wolf which was a captive Siberian crane who lived up to be 83. There are 15 species of cranes living today and nine species that died a long time ago. The demoiselle crane are very high fliers flying over the mountains in the Himalayan Mountain range. Cranes are related to the rails coots trumpeters and limpkins. The western whooping cranes population migrates through the great plains to coastal Texas and the eastern whooping crane population migrates from Necedah National wildlife refuge in Wisconsin to Florida.The scientific name of the whooping crane is Grus Americana. Black-crowned crane is near threatened because of the pet trade.
Q:What is the difference between an egret and a crane?
an egret is any of several herons and several of which develop milky white plumes during the breeding season,some herons are called egrets. Cranes are a family of large, long-legged and long-necked birds Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes’ necks are a shorter than those of heron.Herons curve their necks into an “S” shape and when they are flying they pull them totally back, while cranes necks’ stick straight out. Cranes also have shorter beaks than herons.
Q:Is it safe to lift a heavy load using three crawler crane for the purpose to rotate the item?
Need manufacturer model of crane and weight size of item. Rotating should not be a problem if you call the manufacturer of the crane and get the lift weight approved.
Q:How do you kill crane flies? ew i hate them so much?
I killed a Crane Fly because I thought i was a type of mosquito. Now I feel rather bad about it. After looking seeing how Crane Fly's look online.
Q:What is the full story of the legend behind the 1000 origami cranes wish?
It okorder.com/ I'll keep looking and see if I can find out an origin and add a bit more later.
Q:In Stephen Crane's novel The Red Badge of Courage, why is the war itself not even named?
There are references in the book to events during the Civil War. In addition, the time of publication by this American author left no doubt in any American's mind which war it referred to. The Spanish American war happened after publication and the primary war on everyone's minds was still the Civil War.
Q:How were Railroad Steam Engines from 1830 to 1890's recovered before the advent of the Wrecker Steam Crane.?
Old Man Dirt is right. Block and tackle. Remember too those early engines weren't that heavy. The most common type from 1850 to the 1890s was the 4-4-0. They, and the other types were usually between 25 and 60 tons. I don't necessarily collect old rail photos, but I've seen many hundreds in other people's collections. And early locomotive salvage was usually block and tackle, with another engine brought in to furnish the muscle required. Since this could be a lengthy process if the wreck was extensive, a temporary track, or sometimes called a shoo-fly would be built to move trains past the derailment, or to enable getting another engine and hoisting equipment positioned.
