QTZ40A (4708) FAQ
Q: What is 3 main mechanism of the tower crane?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
Q: What is the principal to quote the right tower crane to the client?
A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.
Q: What can we do for the clients in the market and after-sale service?
A: There is branch office for us in the kingdom and she could provide any commercial assistance for the clients; our exclusive agent would fully represent lifting machinery for business communication and rapid & professional technical support.
- Q: What are the basic parameters of a tower crane?
- The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...
- Q: What are the lifting moment requirements for tower cranes?
- 2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device
- Q: Do large semi-submersible crane vessels such as the SSCV Thialf propel themselves to work sites or are they carried on heavy-lift ships. I understand they have propulsion systems but the just seem so bulky, inefficient, and slow to move across oceans on their own.
- Very large capacity crane vessels have propulsion machinery for manoeuvring when on station. The most modern designs of semi-submersible vessel use them to achieve 'dynamic positioning'. Older designs used the propulsion systems to assist when deploying the anchors in the correct pattern. The vessels are towed by tugs when making deep sea passages. First generation crane vessels had much smaller lifting capacities and were either constructed on conventional hulls or were converted from existing ships. These types were capable of making ocean passages using their own propelling machinery.
- Q: the question is :Two cranes can unload a ship together in 15 hours. The faster crane takes 16 hours less than the slower crane, if each were to unload the same ship alone. How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
- No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
- Q: Is there a certain direction and reason a construction worker will leave a crane facing a certain direction.
- They would generally try to point the boom (the longer part of the crane) away from the prevailing winds. This reduces stress on the tower - but it's not really a big deal.
- Q: I saw da construction of the upcoming tallest building in da world in Dubai,how did da crane get on top of it?
- it climbs the tower as the tower goes higher. the crane has 8 mechanical legs that it lift it self mechanically.like a spider in a tree or as the tower goes higher workers add a piece at the bottom of the crane using hydraulics
- Q: how do you make an electromagnet crane?
- Well I guess you would need a big electromagnet, a large power source and a crane. You would need to wind a huge coil around an iron bar, feed it with lots of direct current and stick it on a crane.
- Q: I am looking for guidance on determining the optimal design parameters for the design of an overhead travelling crane when considering a span of 60m and a lift requirement of 2500Tonnes. If not possible what would be the maximum lift for the same span
- is the 60 is the traveling distance or the span? if it is the span then this no way can be achieved or found, also 2500 tons is not logic for a single lift, you need to verify the design requirements. Usually crane span is related to structural frame spans, the lift has to be a practical one, which ranges from 1 ton to a 250 tons which is again very rare, majority traveling cranes are from 1 ton to 25 tons
- Q: Vtwin doc helped me out with this dam thing recently Im thinking he has the 411! So here goes: My friends coil went bad and we used a single fire coil on a dual fire ignition. V twin doc showed me how to do that. But it still doesnt quite run proper. So here are the settings:Its set at 5900 R.P.M. limit,with advance slope at 9.the rear cylinder is set at 0.Its set on dual fire,its set on electric start.and its set on multi spark not single.Its a crane fireball hi 4e model 8-3100. It cranks for a bit before starting and runs a little rough at low R.P.M. ran just fine with the stock coil.

- Q: When should a crane be load tested?
- if crane using regularly more then 8 hrs test should be every 4 months 8 months and full sevice at 12 months............
