• Trolleying mechanism: BP185; power: 18.5 kW.

2. Electrical control system
With PLC control, the electrical control system enjoys better reliability and safety. Produced by professional manufacturers with advanced foreign technology, the electrical elements feature service lives that are 3 or 4 times longer than that of domestic products, less faults, easy maintenance and repair as well as reliable operation.

3. Technical features
• The crane boasts of multiple operation modes and wide application;
• The complete machine adopts internationally well-received beautiful shape;
• The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world's most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;
• The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;
• A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane's reliable operation.

Q:Calculate how much power the crane has?
the crane ?? The crane is not defined.
Q:Do they mention Seneca Crane by name in book 1 (The Hunger Games?)?
You know what? I thought they did but I just went through my copy again and I can't find any mention of him by name. I apologize for the incorrect answer I gave earlier.
Q:How do you kill crane flies? ew i hate them so much?
They come inside the house looking for mosquitoes! Crane Flies are great mosquito hunters, in fact we call them skeeter eaters. I'm from the south, plenty of mosquitoes here and we love Crane Flies. They're totally harmless to people or anything else besides mosquitoes, and since mosquitoes are proven carriers of numerous deadly diseases such as malaria, yellow fever, and the dreaded Nile virus, I'd much rather have Crane Flies around me than mosquitoes. Do yourself a favor and learn a bit more about these fascinating and very helpful critters, I'm sure you'll be willing to cut them a little slack if you do. edit Leolupus is correct! It turns out after 40 years I was completely wrong ~ they do *not* eat mosquitoes. I have been informed by an expert (my father-in-law, who is an entomologist at Texas AM and laughed at me when I mentioned this question my answer) that adult Crane Flies eat flower nectar, decaying vegetation, seedling plants, mosquito larva (but not adult mosquitoes) or nothing at all depending on their species. They are, however, harmless to humans since they're totally unable to bite, though they're considered a pest by some farmers due to the habit of some species of dining on young crops. Oh well, sometimes you start out trying to teach someone a lesson and you end up learning one instead. Thanks for bringing up this subject, Bebe :-)
Q:What is the purpose of the stinger on Crane Flies?
ovipositor?
Q:Tower crane and tower crane 5
Vertical transportation can be done with elevators, construction lifts, and Longmen racksTower cranes and tower cranes are one thing
Q:How to do a simple Fujian White Crane block?
Not sure if there is a video but if you check out Analysis of Shaolin Chin Na by Dr. Yang Jwing-Ming you might find something.
Q:Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace...?
Apparently that IS what they were called. Who knew? I would have guessed something a little more poetic like Dragon's Tail because it's long and straight, swings on a pivot and frequently has notches along to top for latching the bails of cooking pots and the like. Crane sounds so... so... ordinary.
Q:A crane lifts a 2.75x10^3N bucket containing 1.20 m^3 of soil (density = 2.00 x10^3 kg/m3)to a height of 6.95m?
Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
Q:How high the tower crane needs to be installed with the wall pole. How is it stipulated in the national standard?
The independent height of the tower crane is determined by the manufacturer's manual. The independent height of the tower cranes of different manufacturers and different types is different. The installation of the tower crane needs to be installed with a wall rod. The specifications are stipulated in the instruction. The national standard requires the instruction of the manufacturer's manual.
Q:How to fix the cable on the tower of QTZ125 type tower crane?
let the main cable and metal member completely separated, safety code for tower crane and tower crane installation, use and dismantling specification is not clear and specific practices, according to my experience, in accordance with the methods mentioned before can do check, usually meet the requirements.
