Q: Tower crane 5610 why is it called QTZ63?: QTZ refers to the lifting tower crane, and the 63 is the torque, the unit is tons x meters, generally in accordance with the crane's nominal gravity moment to sub model, which level is close to which model. The latter four numbers, the first two represent larger, the unit is M, and the latter two represent the largest range of maximum lifting weight, the unit is KN

Q: what type of hydraulic oil does a 2007 liebherr LTM 1160 5.1 crane take?: You're telling me you've been entrusted the control of a crane capable of reaching 565 feet up an you don't know what hydraulic oil it takes?? Jesus Christ mighty... First off, it's in the owners manual, second off it's probably on the resivoir cap.... If you couldn't figure that out you shouldn't be allowed near the damn thing...

Q: Please try to give information on the questions bellow: .What the climate was in the Japanese Crane's habitat (high, lows, averages, precipitation) . Plants in the Japanese crane's habitat .2-3 major animals in its habitat .2-3 minor animals in its habitatTHANK YOU SO MUCH!!! .: in the east Hokkaido, the north island of japan. some japanese crane in russia goes to north korea in winter, but cranes in hokkaido stay all through the year.

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?: contact whatever agency issued the license in the future, remember to keep the original yourself and give the company a copy

Q: its dead im so scared if thes so called flys i tired to kill it but wen ever i get some thing to kill it its hideing: Crane flies, also known as mosquito eaters or mosquito hawks, are harmless. There is no reason to fear them. They do not bite or feed on anything and only live a short time, maybe 24 to 48 hours. I have them in my house quite frequently during March and April. They fly really slowly and don't try to fly away if you want to smack it with a flyswatter. They are big and ugly but that's about it. They seem to be more active at night and are attracted to light, kind of like moths. Maybe you could lure yours out of your room by leaving a light in the hall and other rooms dark.

Q: Ty Crane is the star basketball player for st.francis, what is he doing now? Where is he?

He smiled eveytime he said he was a movie star. Go to Venice beach by the weights and courts and you will see him there!!

Q: What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?: As for the reasons, the main consideration is the actual needs.

Q: I need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?: 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: Military Action movie with bunch of cranes at the end?: Cranes like construction equipment or Cranes like the birds?

Q: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?: I am not sure that you are giving us sufficient information. I presume that your crane truck has the boom hinged quite close to the ground, but I am sure that the specified lifting weights will not be achieved until the boom makes an angle of at least 45 degrees with the ground. The 115 foot boom will then sweep a circle of 115 x cos(45) = 81.3 feet, and lift a maximum of 115 x sin(45) = 81.3 feet above the hinge. If the boom is elevated to a 60 degree angle, the circle swept will be only 57.5 feet, but it will lift 99.5 feet. If the boom is lowered to 30 degrees, the circle swept enlarges, bt the distance lifted drops, and the weight lifting capability will also be derated. If the crane has a tower and the weight rating is for a horizontal boom, the maths are quite different.
