Main Features of Tower Crane
1) This series of tower cranes, ranging from QTZ40 to QTZ400 has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work efficiency. They can be widely used for the construction of high-rise hotels, residential buildings, high-rise industrial buildings, large-span factory buildings and tower-like buildings like tall chimneys.
2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed. 3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

FAQ about Tower Crane
Q: What serice you could provide? A: Providing timely delivery, standby engineers are ready to slove any of your problem Providing all-embraced warranty of products quality, worksite installation guidance 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: What species of crane/heron is at 3:07 of this video?
- It is a stork, not a crane or heron. The painted stork, Mycteria leucocephala. The first pic in this link does not make the identification clear..
- Q: I have recently mounted a Meiller MK 40 R / 2 crane on my truck and I wonder if my truck's hydraulic pump can support it without problems. I have a Mercedes-Benz 813 truck of 1987 and the crane is more or less the same years by the way. Should I change my truck's pump?
- Check what the hydralic specs. of the crane are. Then see if your truck pump can supply the output pressures and volume.
- Q: would 2 500 ton crawler cranes be able to lift a 854 ton bridge section 80 feet in the air?
- Sorry, okorder /... The farther from the center of rotation of the House, the less a crane can lift. That same crane can only lift 57.5 tons at 22 meters from the center of rotation of the House. Ben
- Q: The mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center of gravity at G2. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn if the suspended load is W = 38kip . Neglect the thickness of the tracks at A and B. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn.
- The key here is to simplify this as much as possible The equation is really: mass 1 x length 1 + mass 2 x length 2 = mass 3 x length 3 G1 * 6 ft = (G2 * X ft) + H3 * X ft) G1 = 116 kip G2 = 29 kip H3 = 38 kip Now it is an equilibrium of torque about the point where the boom pivots: 116 kip * 6 ft = 29 kip * Xft + 38 kip * Xft solve for X feet: X feet = 10.388 ft So the crane is in equilibrium when the load is length1 + length 2 times the mass = mass of motor * length 3 (10.388 ft * 29 kip) + (10.388 ft * 38 kip) = 116 kip * 6 ft The boom forms a triangle with the hypotenuse equals 12ft + 15 ft = 27 ft. The bottom of the triangle is 10.388 ft + 10.388 ft = 20.776ft So we have two sides of the triangle and now just need to find the angle where the triangle forms with those two sides: cosine of angle = adjacent side / hypotenuse cosine of angle = 20.766 / 27 = 0.7691 and the arc cosine of that = 39.7 degrees So rounding it off, angle of crane = 40 degree
- Q: He is one of my favorite poets. I want to read more of his work.
- How about my favorite poem about Hart Crane? AT HART CRANE’S TOMB by Glenn Robert Swetman In his mind’s dark, he spoke a frivolous age where marriage of the like was spring, where vitelline worlds of virgin instinct were crushed in the obscene cleanliness of a raccoon’s paw. Did he imagine that his great sun could come trailing yellow handkerchiefs of light, like a queer comet? No, there is something out there that commands, and not worlds of perfect clipping will turn these rotund hedges into maypoles—and live. That’s why the green expands as it reaches. He must have seen this finally. His leap Into the green sea was, aesthetically, clean.
- Q: The story I'm writing that has Frank Crane in it is here. Is there a better name I could be using for the protagonist?
- I just read your skimmed through your story very quickly. His personality from what I got from the story seemed to fit the name Frank Crane very well. I like the name for that character. Not sure what other name options you have in mind though, maybe you should post some other naming options. BTW, cool story.
- Q: who has played their respective character the longest ? i'm pretty sure it's kelsey grammer but was hoping to get a few responses.
- Kelsey Grammer has played Dr. Fraiser Crane for 20 years... 10 years on Cheers and 10 years on Fraiser....(1984-2004) Belzer has played Detective Munch for 15 years...(1993-2008)
- Q: We had a very large tree removed from beside our house. The crane parked in the driveway and caused four very large depressions and crushed concrete.
- Yes- it almost certainly will be covered. Most (if not all) homeowners policies provide coverage for driveways, walkways, etc. See your policy for specific language. I was an adjuster for 15 years, and I handled this sort of claim on a regular basis. It is very common for large vehicles to damage driveways, especially dump trucks. As long as there is sufficient evidence that the crane caused the damage (rather than normal wear and tear) it will almost certainly be covered. Your homeowners insurance will then subrogate against the tree removal company.
- Q: What is the load moment of a crane?
- The load moment for a crane is a number measuring the weight of the load lifted times the distance between the mass and the centre of the crane's superstructure. For example, a 20 ton weight lifted at 5m away from the crane (in reality, right next to it!) gives us a load moment of 100 ton*m, the same as a 10 ton weight lifted 10m from the crane. Cranes can handle higher load moments closer to the crane, so really heavy lifts are always done from very close to the load.
- Q: What is the theme of the poem A man to the universe by Stephen Crane?
- In the poem “A Man said to the Universe” by Stephen Crane three distinct images appear as the reader relates man and universe as they fit into their cosmic role. The simplicity of the five line poem envelopes man’s perception of his place among the universe, the universe’s perception of its role in the order of life, and the relationship of both man and universe in regards to the enormity of the cosmos. Collectively, these three components create a profound thought on creation. By Folrani Adewale
