- probably not larva of crane fly...they live in the soil outside. Describe or post a pic what you have
- Q:Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.
- I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
- Q:Minimum QTZ63 tower crane special electric box open for many A
- Tower crane (tower crane) is called tower crane, also known as tower crane, originated in Western europe. A revolving crane mounted on top of a tall tower.

- Seneca Crane was the previous Head Gamemaker. He was the one who didn't think past Katniss and Peeta eating the berries. President Snow makes it evident that he was executed for his mistake with the games. I still don't understand why she did it, or why they were so shocked. It probably just offened them, or maybe it was something of a threat, that she'd meant to get him killed. Who knows?
- Q:i know there is a lot of styles in the crane and the praying mantis and ba gua. then what types are there? and what is the most powerful one??
