Providing ample spare parts and training of operation and maintenance
Engineers have more than 20 years' experience in tower crane, ready to solve any of your problems.
Q: What kind of steel used for tower crane ?
A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.
Q: What about our tower crane warranty?
A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.
Q: What is 3 main mechanism of the tower crane ?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
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: How come you never see cranes being transported from one site to another?
- Many are too large to be transported whole, and are assembled on-site (or even build for a single on-site use).
- Q: Write a fully developed paragraph that contrasts the effects of war in two of the following works: Cranes, Thoughts of Hanoi, and Tokyo.
- Hanoi To Tokyo
- Q: What is YOUR take on Louis Crane's idea of meduso-anthropic principle?
- Well, weak- anthropic beats the hell out of strong- anthropic. One cannot, in good conscience, postulate God from the improbability of a good primordial soup kitchen, when beating the odds is the prerequisite for anything evolving sufficiently to be amazed. Life, however, plays hell with probability, because it’s possible for an improbably complex thing to create as many improbably complex things as energy allows. Introduce evolution, crank out a tool user, it gets worse. One dedicated farmer can create a vast and profoundly improbable flourishing of life. Now if we move out into the universe and find a vast and improbable flourishing, we will have cause to suspect the existence of cosmic farmers. This especially because it appears we are evolving towards that state ourselves. Dressing up this concept in pseudo science though, strikes me as a bit pretentious. Which is my take on Louis Crane's idea of meduso-anthropic principle
- Q: Where you stand on one leg with your hands up and out to sides.Isn't standing on one leg in a fight leaving you exposed and vulnerable? What techniques can you actually do from that stance anyway (other than jumping up and kicking with the leg that was on the ground like the karate kid).
- Good question. Apart from the aspect of training, if you use it as a stance like in The Karate Kid in a real street fight or in a pub, it is comically useless. Movies are only movies and the moves are choreographed to captivate the audience's romanticism with Kungfu. But, having said this, the crane stance if used as a transitional move is a practical technique but both outstretched hands are either spear-hands or tiger-claws, not crane-beaks rising from the sides as in The Karate Kid. Or, if targeting only to the frontal opponent, both hands are forward, one fore and the other behind the front hand. The lifted leg is a frontal leg block either with the shin or knee. The knee must reach your solar plexus as a proper position. The whole centre-line is protected for an immediate instance, and is particularly used when there is a sneak attack from the front. But, don't ever use it as a stance waiting for an attack nor with any fanciful stances for that matter in real situations. To be effective with this technique, the person must be able to resist a frontal push while standing on one leg. To achieve this, he has to spend long hours on the 'horse-stance'. The common term for this single-legged stance is Golden Cockerel Standing On One leg, Jin Zi Du Li (my romanisation of Chinese is not to be trusted, but it sounds somewhat like that in Mandarin). As I said earlier, this is a transitional technique and really what follows after is the interesting part.
- Q: What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
- 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 3, tower crane, such as lifting weight limiter, amplitude limiter, height limiter and load torque limiter limiting device, and travel limit switchestower lights wind instrument, wind clip rail device ladders athletic supporter circlewalkways and railings.

- Q: Who do you think was better and who would've won if they faced.
- Gotta go with Willie. The only match I ever saw Mosconi play was in Chicago back in 1964. He was down 46 to 14 going to 150. When he got to the table he ran 136 and out for the win. It was incredible. I never saw Crane in person and saw only one film of him. He ran 150 and out on Cowboy Jimmy Moore. A good friend of mine was telling me a story about the time he was in Johnston City, Illinois. Richie Lawrence was at the table. My friend was seated in front of Crane. As Richie was shooting, Irving Crane was telling his friend what Richie should be shooting every shot. Richie did just the opposite every time. The neat part about it was... Richie ran 150 and out... and never shot the right ball. Gotta give Willie the edge. Good question.
- Q: The arm of a crane at a construction site is 12.1 m long, and it makes an angle of 30° with the horizontal. Assume that the maximum load the crane can handle is limited by the amount of torque the load produces at the base of the arm. (a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N?(b) What is the maximum load for this crane at an angle of 35° with the horizontal?
- (a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N? τ = FL τ = 500(12.1cos30) τ = 5239.45 τ = 5240 Ν?m (b) What is the maximum load for this crane at an angle of 35° with the horizontal? τ = FL F = τ / L F = 5239.45 / 12.1cos35 F = 528.6109... F = 529 N I hope this helped. Please remember to vote a Best Answer from among your results. It's good karma as it keeps things in balanced exchange.
- Q: A crane lifts a 2355 N bucket containing 1.81 m3 of soil (density=2084 kg/m3) to a height of 7.56 m. Calculate the work the crane performs.
- I will try to make it very simple. First lets convert the 2355 into a mass. 2355/9.81 = 240.06 Kg Then, we need to get the mass of the soil. Density (p)= m/v m= pv m= 2084*1.81 = 3772.04 Kg Total mass= 4012.1 Kg The final step is to calculate the work done. It can be solved from two perspectives and both will lead to the same solution. Sol. 1: Since that the crane is lifting an object, then the work the crane is doing is against gravity which is calculating the gravitational potential energy gained by the bucket. GPE= mgh= 4012.1*9.81*7.56 = 2.99*10^5 Sol 2: Work done= Force*distance moved in the direction of the force The force in this case will be the weight of the bucket. Work done= (4012.1*9.81)*7.56 = 2.99*10^5
- Q: electromagnetic crane
- Current sent through a coil of wire creates a magnetic field, which can be used to pick up ferromagnetic objects. Turn off the current, and the field will turn off (although it might take a few seconds to turn off all the way), dropping the object.
- Q: What are the common problems encountered in hiring cranes for house constructions?
- Access, I assume you need a Franna. Possibly for frames and or trusses to the second level or steel beams. You will be limited by reach if the crane can only access the front of the house. In which case you may need a slew crane 30t or larger. Know the weights of what has to be lifted and the distance from the crane to where it will be placed. A crane cannot set up or travel over underground services or recently filled excavation. These things could mean the crane has to set up even further away from the house. If the crane is for unloading trucks, access again. Cranes need to stay about 3meters from power lines which is a common problem bringing gear onto site. While a slew crane generally sets up in one position for all lifts (some can travel) a Franna is designed specifically for pick and carry. It can unload trucks and travel the gear onto site under the power lines. Provided it isn't lifting extra large items. Speak with the provider about what has to be done, it will be all to familiar for any decent company. As long as access is fine and underground services won't hinder you they should know exactly what you need. Be prepared, usually a minimum 4hr hire. If you think the task is going to take longer you need to plan what has to be done and have everything ready for placement. Organization is paramount, you don't want a crane and it's crew sitting there doing nothing because you didn't plan ahead. Hope this helps, I could have been more specific if the question had some details.
