Q: How does the torque of a construction crane relate to the torque of a car?: In an automobile, you are looking for torque over a wide range of speeds and loads. A crane does not need to have a great deal of speed in terms of lifting an object but does need a great deal of torque. The result is an automobile needs much more horsepower to meet its goals while a crane can actually lift a huge load with a much smaller amount of horsepower. I personally can remember a lift on one of the construction projects I was field engineer on. The lift of 650,000 pounds was made with two 85 horsepower Ford gasoline engines and two industrial gear boxes.

Q: Is it to do with visibility?What are some other colours of cranes?: Here is NZ they are normally yellow

Q: i was reading this chapter in the book Catching fire (part of the Hunger Games Series) and this one part said she wrote Seneca Crane on the dummy with mud,, who is Seneca Crane?: Seneca Crane was the Head Gamemaker. When Katniss and Peeta took out the berries, President Snow wanted to blow them up to bits but Seneca let them through. He was executed after because of this. “If the Head Gamemaker, Seneca Crane, had had any brains, he'd have blown you to dust right then. But he had an unfortunate sentimental streak. So here you are. Can you guess where he is?” he asks. I nod because, by the way he says it, it's clear that Seneca Crane has been executed.

Q: what would you wish for?also, when your done making your 1000 cranesm what do you need to do next? to like, make your wish come true??: huh LoL

Q: Notice of tower crane: Please refer to the technical regulations for the safety of installation, disassembly and use of tower cranes in construction;The following is copy:3 installation of tower cranes3.1 conditions for installation of tower cranes3.1.1 tower crane installation unit must have the construction administrative departments issued the contracted professional qualification and heavy equipment installation engineering construction enterprises safety production license. Tower crane installation units must be engaged in the installation of tower cranes within the scope of qualification permit.In addition to the professional and technical personnel who have the qualification standard, the installation units of 3.1.2 tower cranes shall also have professional personnel who are in line with the project. The person in charge of the project, the project manager and the full-time safety management personnel shall have the certificate of safety production inspection. Tower cranes, installers, electricians, drivers, signal engineers, cable operators should have special construction operation qualification certificates.3.1.3 construction units shall sign professional contract for installation engineering with the installation units, and make clear the responsibility of both sides for safety in production. In case of general contracting of construction, it shall be signed by the general contractor and the installation unit.

Q: I need to draw an injured crane (the bird) with an arrow in its wing, lying on the ground...preferably with a splayed wing.How do I draw this? Sketches would help.Thanks.: Why do you want to draw an animal that is suffering? Draw something that is positive.

Q: Captain Kirk, TJ Hooker or Denny Crane?: I would like to have a man with Kirks body around but with a little of Danny Cranes reality personality. I don't know who TJ Hooker is and I don't think Willam Shatner played him. It sucks that shatner has let himself go like that. Such a shame compared to how he once looked.

Q: Tower crane demolition safety technical disclosure, how to write?: Baidu search:Tower crane removing and lowering joint safety technical disclosure.

Q: I have tried so many times to make that crane, and i always fail. Can anyone give me a video that is really good, or instructions that are really good and have pics? Thanks in advance!: The okorder /

Q: please tell an article about electromagnetic crane?: electromagnetic crane has a huge electric magnet instead of a hook. this magnet is operated by an electrical current. when electric is switched on the magnet becomes magnetized,allowing metal objects to be picked up just like an ordinary magnet.when Electric is turned off the metal object will fall away, as it is no longer magnetized.
