Q: How do they get the tower cranes (the ones used to build sky scrapers) so high? It's not like they can ship them all in one piece so how do they make them taller? I've always wondered that...: Building Cranes

Q: 3years after I quit a job,I am once again looking toward the same field it's just that in my old job they helped me get a crane license when I left the job they kept my certification .How can i get that info without asking my old work for it,or would i have to take the course over?: If it's still valid all you need to do is get a duplicate from the agency that issued it.

Q: I had a dream and it wos really scary so realistic i woke up crying and could go to work the next dayi was in my house and woke up and came downstairs and there were letters on the floor and someone was picking them up then i looked outside and there wos a big fire and a crane had fallen down and explosion and everyone was dying their faces burnt i burst out crying. what does it mean?: Probably some stress or fear is looming large in your subconscious mind. Scary dreams often occur when you have something that is stressing you. That is assuming you didn't read some book or watch some movie that brought it on, that is another possibility. Often we replay images we have in our heads from the day before. I don't think it is an omen or anything. So, be glad to say it was only a dream.

Q: What is the difference between a crane and a crane in a tower crane?: There are the following differences between crane crane and Signal Engineer in tower crane:1, lifting signals refers to those who signal flags in the works.2, the engineer referred to the engineer who tied the rope in the works.

Q: From what I'm understanding in the first stanza, a women lost her lover to the war because he fell off his horse...Is that right?: Yes, Stephen Crane talks about lost love and sacrifices in his poem. The basic casualty of war. A lover, a father and son are lost in his story and those that are left behind he tries to console. The poem is noted for the ironic use of war is kind. We all know that War is really not kind. The poem’s speaker, simultaneously sympathetic with the victims of war and cynical about the purposes of war, implicitly criticizes the image of the romantic hero, showing in graphic scenes the realities of battlefield death and the emotional torment it causes for those left behind.

Q: Is there a talk show on the radio or TV similar to the Frasier Crane Show where people call in and tell their problems and the doctor gives them advice? One that's either in the Los Angeles area or nationally syndicated?: Here's okorder /

Q: I have three of these little pests hovering around in my tiny bathroom (my flatmate left the window open). I don't like to get close to them, and when they flutter near me I panic. I need an effective method of getting rid of them, that doesn't require me to get close or touch them - I really need to shower, so any advice is welcomed!Thanks, Ashley.: Katheen is right about crane flies not being daddy long legs, and that if you have a cat, you should bring it in your room. You could also use a handy dandy, everyday, all around, fly swatter! Or if you don't have that you could use your flatmate's shoe! or pillow!

Q: No inspector would intentionally overlook a dangerous existing situation re: crane usage in a major city---so what went wrong--never before has this happened and now two majjor incidents?: I believe they are accidents. Crane collapses happen. I had the dubious distinction of helping with the investigation a crane collapse that left the crane operator in an unrecognizable state. It's awful but these things do happen. Was there negligence in some cases on the part of the crane operator? Maybe.
