Q:Where are gears used on a crane?: It's more a matter of where gears MIGHT be used. 1. Gear reduction to lifting cable drum. 2. Gears to rotate the crane, or driving cable drum to extend jib. 3. If a mobile crane, gears to transmit drive to wheels/ tracks etc.

Q:How many stops are there in a tower crane? Where are they located in the tower cranes?: The hook has an upper limit on the windlassThe car has front and rear spacing on the trolley hoistSlewing is limited to the slewing gearAnd the torque limit is on the spireWeight limit

Q:What species of crane/heron is at 3:07 of this video?: Your bird is a Painted Stork (Mycteria leucocephala)... Now that is pink!!!

Q:If I have one week, is that enough time?: It all depends on how fast you can make one paper crane and how many hours you have available each day. If you made 15 an hour for 10 hours each day (150 cranes a day) for 7 days you would have 1050 cranes. You will probably find that you begin to go faster, the more cranes you make. However, after 2 or 3 days you will get sore hands and this will slow you down again. It's easier when you work as a team.

Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you: The maximum amplitude control: when the weight exceeds or prohibit increase load rate of more than 105% or greater than the maximum amplitude (amplitude limit) output control, allowing the car to be near range by car distance to increase amplitude is prohibited.Minimum range control: when the amplitude is less than the minimum amplitude (amplitude lower limit), the output control allows the car to move to a distant range, i.e., to increase

Q:What special operators should be equipped for the installation and disassembly of tower cranes?: According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel; 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel.
