- Q:I'm a little confused as to what the difference is between the crane and the flare boom-____- I'm thinking that the flare boom is what they use to burn off oil I there's a fire, but is that right? And what does the crane do?
- The flare boom is used to burn off gas from the well. It is basically a pipe that directs the gas to a safe location.
- Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
- The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
- 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:When you're training to work in construction, do you need to do a seperate course or qualification in order to be able to operate a crane? Or are all construction workers taught it in training?
- Of course you need specialised training! Crane operators have to sit several courses in safe crane operations. Crane operators tend to just work cranes and not help with general building work as they earn more money and it is only cost effective to have them on site when they are actually needing to use the crane.
- Q:Ok so I am now on my laptop in my room, in my bed and I am bursting for the loo, like really bad. I knew before I went to bed there was a crane fly in the hall (outside my room), so I made sure I went to the loo before I went to bed. But me being me I need it again but i have phobia of those dreaded crane flys. I went out and put the light on making sure 2 close the bedroom door, and then it started to fly towards me so I ran back to my room. I need help cause I don't know what to do?I am petrified of them. My fiance would normally move it for me but he is on night shift tonight.The last time this happend I stayed up all night and went to the loo at 7 am when my daughter got up, I don't want to do that again considering it is only 1:44 am over here
- Crane flies are harmless. They don't bite or sting. You could just get a T-shirt and swing at it if it dares cross your path.
- Q:What do you do to become a crane operator, do you go to school and how long is it?
- OK, first, what kind of crane? there are many different kinds that do many different things. From loading containers at the seaport to high rise buildings. One does not just go into cranes. The more experienced ones, started out as oilers or greasers. Some started out as signal persons. They learned by watching and listening. In the following states you must hold National certification: CA, HA,MT,OR,WA,MN,WV,NM,RI,NJ,NV,NY UT. PA and SC have restrictions now but will be added sometime soon. You can attend a crane school that prepares you for the national certification, but it expensive and not easy for someone without a background working around cranes. There is a lot of terminology and mathematics involved. Not to mention the Federal, state, local and OSHA rules you must practice. Go to your state employment office. They have all the information you need. get to know one of the counselors and pursue your dream. It is not as easy as it seems. But is it a well paying career. Good luck Bill
