Q:as a wife, what can i expect if my hubby joins the navy reserve as a crane operator?
Boot camp is 9 weeks. Then he'll have whats called A school. Im not sure how long that is. He will get paid, but it takes acouple weeks to get into the system, so save up some money before he leaves. Its a great opportonity for your family, the pay is standardized by rand and time in service, googld military pay chart for a better idea what that will be like.
Q:why should we save the crested cranes?
Why shouldn't we? Where do we draw the line when we're responsible for species after species going extinct. Granted, you shouldn't be expected to physically rebuild their habitat yourself if your not up to it; but a small change here or there isn't to much to ask to help save the world, is it?
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:When is this Crane Fly season over?
Crane flies are totaly harmless to humans.They fly for some time and fall down to earth.Ants will take them away.These flies never byte or sting. Pet Cats like to play with it and catch it.They will disappear after some time. Do you know that crane flies spend most of their lives underground in their larval forms, which are known as leatherjackest?. Leatherjackets were very common round here, and are a favourite food of the local crows .These leatherjackets transform into crane flies.Summer is their growth time.
Q:How do you build a crane? (it is for a school project)?
Step by step: 1. Get male crane 2. Get female crane 3. Play romantic music 4. Wait 31 days 5. Voila! you have made a crane!
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:how is a tall crane constructed? how can they put the crane on top of its tall body frame?
They first construct the top of crane on the ground with help from other mobile cranes. This includes the long horizontal part with the operator's cab, and the concrete counterweight. this is then placed on a climber, with which the crane kind of builds and climbs itself to the necessary height. Every vertical section of the crane is placed in the climber. When the piece is in place, the climber climbs to the top of piece from where the next vertical piece is placed and so on. You can see how a crane is constructed in the website I've cited below:
Q:What are the three different types of Cranes?
A very good information is provided so far thanks . i read on many sites but the content on this site is very good. i like to read about cranes and i have also many cranes actually i see many people did same thing he takes
Q:How do they erect a crane without the use of another crane?
Although I haven't seen it done I imagine that especially for very high cranes it's done most often with cables and winches (utilizing a pivot point at the bottom of the structure). For many lower cranes such as those found on vehicles hydraulic lifting is sufficient.
Q:How is a Crane dismantled?
