QTZ40( 4808) FAQ

Q: What is counter weight? How kinds?

A: Counter weight is for balance the suspension mechanism. There are 2 kinds of counter weight, one is made by iron, the other is by concrete. 


Q: What is the function of the monitor?

A: Monitor, namely inspection system (like black box), which could store 10000 tower crane operation reports, and it is recommended to be installed in big cranes more than 16t.


Q: Can you equip with light on tower crane jib, monitor, remote control and anemometer?

A: Sure. All of these could be provided with extra cost upon the clients’ requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.





Q: I was told that this was taking place, so i would like to fax the info to the proper local
Is that a woof woof dog, or a dogman? A dogman is the person responsible for loading a crane. In days gone by, he often rode on the load while it was being hoisted. Maybe some still do?
Q: Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.
I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
Q: quick answer or i'll delete it!

Q: Please help!
this would help you i hope good luck researching
Q: how do they take crane off top of building?
Depends on the building. Either a taller crane is brought in to lift them, or they're lifted by helicopter. And sometimes a building effectively builds itself, and the crane moves up with the construction platform after being constructed at ground level. Will still need a helicopter to remove it of course.
Q: do they eat them or what??i hear about hunting them and i think cool but what do you do with them i mean do they tast good??
