Q:Grade 4 build a working crane Help!?
Simple crane? Get a spool, maybe one from sewing thread. Attach it to a small base so that it can rotate freely. Put a pencil through the middle tight enough so that when the pencil rotates the spool rotates. Glue a tab on the end of the pencil at a right angle to the pencil so you have a handle. Attach string to the spool and then maybe a ruler or stick to a base lined up with the spool like a crane. Put a couple of eye hooks on the stick and feed the string through so it hangs down at the end of the stick, like a crane cable. At the end of the string put a springy clothspin so that when you pull the string the clothspin opens and closes. Now you can lift and lower the clothspin by rotating the spool with the pencil. Pulling on the string opens the pin to pick up things.
Q:Emergency treatment of interrupted electricity during lifting of tower crane
When the power supply fails, you should first remove the things that are stuck in the gear!
Q:What is the difference between a tower crane QTZ31.5 and a QTZ40?
the length of the arm is 42-48 meters; the elevation is 29-32 meters.

Q:If a friend folded a thousand paper cranes for you what would you think?
If a friend folded even a single crane for me it would be enough.I'd feel lucky for sure.Its the feelings of your friend that counts not Sadako's theory.
Q:How often should the crane be inspected regularly?
Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.
Q:i want to know about the container handling cranes.weight,height,color,heat and moisture resistance,...?
You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle. Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C. Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants. All true dockside cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are portable cranes that operate without one. There is also more than one crane manufacturer out there - all will have their trade secrets that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.
Q:What points does Crane makes about Courage in The Red Badge Of Courage?
The Author Stephen Crane describes this loss of individuality as a key part of the war machine. This sense of selflessness can be a good thing – like when feeling part of the human race will make you jump under a subway to save another man, or the way you care more about your team winning the game than you do about scoring that last point yourself. But it can also be dangerous, as The Red Badge of Courage reminds us. Cogs in machines usually don’t think, and no thinking means no judgment or discretion as to whether an act is right or wrong.
