QTZ31.5（4264） 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 do lattice boom and hydraulic boom in cranes mean?
- LATTICE BOOM: See first link. This is where the boom (the portion used to support the load) is made like a lattice ... i.e. interconnected trusses and girders. The cables for lifting the load are run from the base of the boom to the load over pulleys/gears located at the boom's tip. The boom itself is NOT adjustable in length or in angle. HYDRAULIC BOOM: See second link. This crane uses hydraulics to adjust either the length of the boom, or the angle at which the boom joints intersect. It looks more like a single beam construction, although its probably closer to a tube type design (hydraulics may be inside or outside the arm). The load is raised/lowered by cables operating at the end of the boom ... not necessarily tied back to the bottom of the boom.
- Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
- Part: foundation, tower, wall unit, excessive section, lifting mechanism, rotating mechanism, lifting mechanism, the lifting arm, a balance arm, electrical control, safety protection device etc..Main technical parameters: maximum lifting weight, amplitude and maximum amplitudeLifting torque = magnitude X maximum amplitude lifting
- Q:What is the difference between a crane and a crane in a tower crane?
- Informal: hoisting signal worker: refers to the signal flag!Cable man: rope!
- Q:I know they will leave because last year they left after a few weeks. I have seen that they normally leave after a month. They annoy me and I want them gone. They have been around since the end of February or beginning of March. Does anyone else have these in their house. It seems like they are leaving slowly usually there is like 1 or 2 a day in moms room but the last 2 days there have not been any. They have been in my room, just one a day it seems like and maybe one in the kitchen. We swat them or spray them and they die eventually but when will they be gone atleast for a little while?
- Crane flies are totaly harmless to humans.They fly for some time and fall down to earth.Ants will take them away.These flies never byte or sting. Pet Cats like to play with it and catch it.They will disappear after some time. Do you know that crane flies spend most of their lives underground in their larval forms, which are known as leatherjackest?. Leatherjackets were very common round here, and are a favourite food of the local crows .These leatherjackets transform into crane flies.Summer is their growth time.
- Q:I need to do a report on how cranes topple, moment (physics) and there correlation (relasionship).I am an idiot and have forgotten what moment is. so please explian that, how cranes topple and why they dont topple, and the correltion between the two!thank you
- First of all, let's think of a crane like a giant see-saw, where the plank itself doesn't have any weight. Now cranes have big weights on one side of the pivot, which they can move along (I think, I may be wrong). These cause what is called a 'turning moment'. The further out from the 'pivot' they are, the greater the moment. The other consideration with a crane is it's load. Generally, this is carried a lot further out from the pivot point, on the opposite side from the weights. Now consider this. If you have a small child sitting on the end of a see-saw, you will be able to balance them with a larger person sat closer to the pivot. This is the principle on which cranes work. The moment is the force times the distance from the pivot, and it must be balanced turning each way for the see-saw/crane not to topple. This is somewhat of a simplification, but hope it helps.

- Q:Is there a crane big enough to lift Hillary off the yoga matt when she has finished her yoga?
- You wouldn't need a crane, all you'd need is a hershey's bar and she'd wattle off the yoga mat. Or, you can present her with facts about the destruction of her e-mail server, the fact that she allowed innocent people in Iraq and Syria to die, or the fact that she hit the reset button with Russia, and she'll RUN AWAY from the yoga mat.
