QTZ125 FAQ
Q: What is the building hoist main purpose?
A: Building hoist equipped with double or single cabin to transport the materials and labors up and down. It's the ideal construction equipment for vertical transportation in the field of construction.
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 tower crane?
A: Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.
- Q: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
- Q: How about the installation and disassembly of the tower cranes?
- Authorized by the national security inspection department, the local special operations training school or the technical quality supervision bureau, after the study, assessment, qualification and graduation permit, will give you special operations installation, removal operation certificate.
- Q: How the cranes can stand without any tipping with huge counter weights on its back? If there is no suspended load also the crane is is still stable with huge counter weights on its back. How it can possible? Why crane is not offballencing while we adding extra counter weights on it without any suspended load?
- Usually the counterweights can move back and forth on an arm. They are moved toward the crane when there is no load and away from the crane when there is a load. If the counterweights can't move, then the crane must be designed to hold (at least) the minimum counterweights in their fixed location. As the crane gets loaded, the net moment decreases, and then increases in the other direction as more and more load gets added. It is still likely that the maximum design moment when loaded far exceeds the moment due to the counterweights on an unloaded crane.
- Q: I was wondering if this is possible. The wall we have designed is very close to an existing retaining wall. In order to properly form and waterproof the wall we would have to demo that existing retaining wall. My idea was to build it off site, waterproof it, and then crane it into its location. Is this possible? any similar methods? thanks
- If you use precast concrete sections it can be done. You can even have a decorative side if that is required. You might need to have some form of interlocking connections to tie the whole thing together. Depending on its height there might also be a need for anchors to keep it from trying to tip. Without more very detailed information it is difficult to really answer this question. As an example: depending on the type of soil and the height of the wall it is possible to remove the existing wall and install a new one in a day if you use something like a keystone system.
- Q: What role does the tower crane torque limiter play?
- The torque limiter can play the weight overload or working radius beyond, beyond the technical performance of the tower crane at the moment, immediately cut off their own lifting or variable power source, will send the alarm signal to prevent the occurrence of accidents.
- Q: Cranes are normally used in construction in most countries.But I saw some photos that show Iranians are hanging criminals in pubic with cranes instead of gallows.Is it more painful to the dying criminals to the last moment?Do you know why?
- they probably didn't have the proper arrangements to carry out the punishment so they used cranes instead of gallows. who knows? but weird really. and it wouldn't be more painful... err... the purpose is to snap the neck... ouch :(
- Q: how do cranes get assembled ? on building sites?
- By people.
- Q: What is the most amount of weight lifted by any crane?
- Buffalo Hydraulic built a crane for NASA to lift their launch pads. The heavy one weighed about 5.4 million pounds, but the crane could handle 9 million if it had to.
