QTZ40 FAQ
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 is main advantage for manufacturing construction machinery?
A: Our machinery main advantages mainly include: 1. National-level Research Academy for various building equipment for more than 30 years’ experience; 2. Complete quality control system; 3. Nearly 20 years experiences in manufacturing industries; 4. Over 50 engineers along with 6 local partner companies providing worldwide after-sales service;
- Q: what do sand-hill cranes eat-as far as planting a food source for them?
- Cranes eat fish so unless you know of a fish plant, I would put in a large pond with fish.
- Q: Equipment safety of tower crane
- Safe distance tower and transmission line is not up to the requirements of the tower frame door frame to design, erection principle to power erection, do not use metal materials, bamboo and other materials can be used. The distance between a bamboo pole and a power line shall not be less than 1m, and a certain degree of stability shall be taken to prevent the wind from blowing. The tower crane height and bottom bearing size ratio is large, and the center of gravity of the tower body, high torque, braking frequency, impact force, in order to increase its stability, we will analysis the main causes of the tilting of the tower crane has the following:Overloading. Different types of cranes usually adopts the lifting torque based control, when the amplitude exceeds the rated load weight increase or the corresponding weights, the overturning moment more than stable moment of it, it may cause the collapse of the tower crane.Two, inclined hanging. Slant weights will increase its overturning moment, the lifting point will produce horizontal force and vertical force on the crane, bottom supporting point will produce an additional overturning moment, and the stability coefficient is reduced, resulting in tower crane collapse.Three, the tower crane foundation is uneven, the ground endurance is insufficient, the perpendicularity error is too big, also can cause the tower crane to overturn the moment to increase, causes the tower crane stability to reduce. Therefore, we should proceed from these key factors to strictly check, check and check, and prevent major equipment personal safety accidents. State explicitly eliminated the model should resolutely prohibit the use of, in disrepair, tower crane in the identification of the repair, to limit the use of load, tower crane for the use of fixed number of years there is no uniform standards, opinions vary, different places have different provisions.
- Q: Is the tower crane a special type of work?
- The crane driver, scaffolder, welders and other special types are
- Q: the cable of Crane I creates and angle of 30 degree angle from the horizontal and the cable of Crane II creates an angle of 45 degrees from the horizontal.-draw a figure that gives a visual representation of the problem-write a vector to represent the tension on the cable of Crane I-write a vector to represent the tension on the cable of Crane II-write a vector to represent the 20000 lb cargo container being lifted -calculate the tension on both cables. Justify your answer.....please help me!!! thank you!!!!:)
- I find this question very interesting, i'll keep here waiting for the answer.
- Q: How to calculate life span of steel structure? for example, crane?
- With bridges that you would be able to calculate an anticipated lifespan. It is going to now not be very particular. You measure the deflection as a given load goes over it. You also measure deflection with average site visitors.You are taking measurements of what normal visitors is. With this knowledge that you would be able to undertaking lifespan and prefer exchanging bridges earlier than they crumple. Once I was once a engineering student I had a summer time job serving to to experiment bridges.Most bridges and gigantic constructions are designed to are living 50 years I believe. For constructions I have no idea of any measurements you would take. I think it is most often a matter of periodic inspections. The things to seem for are basis problems, cracking of concrete, exposed re-bar, concrete flaking off etc.
- Q: ok I found an injured crane what do I feed it?
- Cranes are omnivores. But I would feed crane with vegetarian stuff like grain, berries, plants, roots, seeds, stems, bulbs, fruits, nuts. But if you want make it non vegetarian then rodents, fish, amphibians, snakes, rodents, lizards, small fish, frogs, shellfish, mollusks and crustaceans.
- Q: Tower crane (tower crane)
- In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
- Q: I got the crane gold 1.6 roller rocker I'm trying to install on my 95 z28 w/ an lt1 and it doesn't seem like they are installing quite right. I got the tall black nuts that hold the rocker down around the stud and the pushrods, that's it. Do I need to use those things that go below the rockers themselves (the things that slide over the stud and the rocker goes over it from the original rockers) or do I just install how I already am with just the crane rockers, black nuts and pushrods?
- on the LT1 they come factory with screw in studs so the crane application should go without any problems the rocker the rocker guide from crane should slide right on to stud you don't use the old rocker guide for that
- Q: (Fujian) white crane
- Google it and see.
- Q: total motor kw-100kw,crane class-m6,the crane should be operated on ups as the conventional electric supply is off , back up time require-30 min.
- To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
