Introduction

According to the France Potain Companys mature technologies and requirements, the series of the mechanism of the buggy is designed, and it is consitituted with the three-phase asynchronous motor torque, the inner planetery reduction gear, wound roll, rack, and other componets.Through voltage regulation and an eddy current brake role can be low, medium, high rate, the electrical own electromagnetic disc brake, a brake steady speed, brake safe, reliable, accurate positioning, the most suitable for Potain tower crane series and replace imported products.

Q:how does a skyscraper crane use moments ?
OK... So what has your homework actually asked you to explain? Can you post the question...? There are moment forces going through a crane, is the aim of the homework simply for you to explain what a moment force is using a specific example ? A crane can be thought of in simple terms as a cantilever, ie one supported end and one free end, the lever arm force as it is sometimes referred to in schools is actually the moment force i.e. the moment for a crane with a boom L=40m long lifting a load of P=10kN would beP*L = 10*40 = 400 kNm, this is ignoring the self weight of the boom, if the boom weighed W=1.5kN/m (thats per meter, not to be confused with kNm which is kilo newton meters) then the moment generated by the self weight would be (WL^2)/2 = (1.5*40^2)/2 = 1200kNm so the total moment would be 1600kNm, so just remember for a point load the moment is force * distance from support ( in cantilevers) hope this helps... :)
Q:the video of the big blue crane wreak?
Big Blue: January 20, 2000: Video of the Big Blue crane accident that happened in the Brewer's Ball Park Stadium on July 14, 1999 in Milwaukee, Wisconsin. Three men lost their lives in the accident. Although the video is only 1 minute and 10 seconds in length, seeing it is an experience you won't soon forget.
Q:it says theres cranes bill in my primer???!!!?
It probably is what you think. I've heard that they use whale parts to make some brands of lipstick so I wouldn't be surprised if they used parts of other animals in cosmetics. =X
Q:gantry crane and generator wiring diagram?
it sounds like you want to run a gantry crane with a generator the generator should have a wire diagram in side the cover. the gantry crane should have the power requirements on the electric motor there should be a tag on the motor. If you are not sure then you need to get an electrician out there to look at the two components and should be able to get you straight
Q:Do cranes eat squirrels?

Q:Origami Cranes, 999 or 1000?
It is susposed to be 1000 cranes. You string them in 10 sets of 10 cranes. [thats how I remember!]Can you send me your way of folding them? I can't find one that works right for me, they always turn out a little wrong. :[
Q:1000 paper cranes a myth?
Yes, it is true. My sister-in-law folded 1000 golden cranes (with some help), when she married my brother. They had them mounted in the shape of a crane and framed. It was beautiful.
Q:in the short story open boat by stephen crane how does he define Fate?
Without doing your work for you, Crane is a naturalist. They believe nature works at random, and is completely unsympathetic to man's plight in the process. Hence, the oiler dies. He was probably the strongest one in the boat. So, how does that translate into the concept of fate?
Q:What is tower crane? What are the types and features?
[definitions]Tower crane (tower crane) is called tower crane, also known as tower crane, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
