Q: Ok, so I figured out that last step after watching an origami tutorial thing on youtube
It okorder / The animations on this site are good, showing what you have to do, without hands in the way.
Q: Iv done some research and I cant seem to find a place that might sell jibs locally here in Phoenix. Iv been considering the ProAm DVC 200 crane but I would also like to see others in like a store. If anyone has any info it would be appreciated!
I went down that path last year in the SF Bay Area in California. I could not find a store that carried any cranes or jibs - so I just started asking around. Stay away from any that use cables to keep the stage steady - we used one at a shoot - setting up is an interesting challenge. I thought I wanted the same unit you are looking at - and decided I needed to trust the crane a bit more with my HDR-FX1... I had to wait longer to save more $, but I really like the crane and tripod kit I ended up with... from Kessler Crane... I never got to see it before I bought it and I was, um... nervous... but I am glad I made the investment - and Eric Kessler is REALLY helpful and great to work with. One of the other cranes I looked at uses a heavy duty PA speaker stand as its tripod base. After watching light trees and PA speakers fall over because of leg failure, I could not bring myself to trust them to hold my camcorder. I can STAND or JUMP on the Kessler tripod and it does not budge. It is rock-steady and really strong. The Hercules head is silk-smooth and the crane-arm and camera stage are steady and easy to manipulate. After a little practice, it now takes me about 10-15 minutes from the time I start unpacking until I am ready to start shooting. That includes mounting the camcorder, setting the counterweights, mounting a portable DVD player with AV-in as the monitor mounted to the tripod-head so I can see what the camcorder is shooting and running the AV, headphone and LANC cables and making the whole thing pretty with velcro strips.
Q: i want to go to school and learn to operate over head cranes
A few places to start the bureau of labor statistics has information on moving trades. You will need certification although requirements vary. The National Commission for the certification of Crane operators lists different types of operators and requirements for certification. States have their own laws about certification and requirements you can check it out, in some states certification is not required yet. I've included a link to the laws for Minnesota. There are a number of companies it would probably help if you are currently working in Construction and for a company that might help pay for the training or learn on the job. I don't know what state your in but there are a number of companies that do training you can do a quick search with Crane operator training. One other resource is the local Division of DET Division of Employment and Training for your state they can help you research your options and vocational counseling. Good Luck
Q: Ever felt like a paper crane?
A thousand paper cranes will grant your wish (or so the legend goes). But a piece of paper can also be used to draw a picture - which is worth a thousand words. Which one do you think I would choose to be?
Q: I was watching Batman Begins and at the end Gorden says that he hasn't caught Crane. Since the villians in the next Batman movie are going to be two-face and the joker will Crane make a reapperance in the thrid movie (if there is one)?
Right okorder reported that an anonymous insider says Murphy will return as Scarecrow in The Dark Knight, but this is an unconfirmed rumor. Also, rumors are that Two-Face would not actually be the villian until the third movie, and that this movie will showcase him as Harvey Dent, the DA and hero, and show him on the path of becoming Two-Face.
Q: What role does the tower crane torque limiter play?
The torque limiter has two kinds of electronic type and mechanical type, electronic type: can show the torque, radius and load, near the tower crane permit torque, there will be a warning signal, although easy to use, the working conditions of cutting has been greatly affected, but not very reliable, easy to damage, the maintenance of trouble. Mechanical type: Although there is no display and can not alarm, but the work of the letter, the structure is simple, not easy to damage, suitable for construction site conditions.
Q: a/ Calculate the lift workb/ What is the power used by the crane when the efficiency is 60%? (Can you explain for me what efficiency means)c/ What will the kinetic energy of the load be when it hits the ground, if it falls from the height 8.5 meters, g=9.81 m/s^2Thank you.
The work done (W)= Force*Distance. Force is 9.81*3000kg. So W = 9.81*3000*8.5 = 250,155 J Power (P)= Work(W)/Time(t) = 250,155/15 = 16,677 W 60% efficiency means that the lift is only using 60% of its maximum amount of power output. So to find 100% (lets call it x) of the crane's efficiency, consider the following: x * 0.6 = 16,677 x = 16,677 / 0.6 = 27,795 W Total mechanical energy in a system remains constant, so the kinetic energy the moment it hits the ground equals the potential energy when it is still hanging in the air. Potential energy = mgh = 3000x9.81x8.5 = 250,155 J You know this is correct, because it is the same amount of work the crane performed on the object to lift it.
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
Q: What is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q: Why are electromagnets on junkyard cranes generally circular in shape?
Easier/more efficient to make the electrical coil circular than any other shape I guess.
