Introduction:
Tower crane is used to lift, lower and horizontally move materials in construction and other industry. It has large lifting capacity and lifting height, wide moving range, and can rotate. It basically consists of base foundation, mast, slewing unit, working jib, counter jib, counterweight, hook, and operating cabin.
Features:
1. 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.
2. The range-change structure drives the dolly to change range on the horizontal arm, 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.
3. The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
4. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.
5. Provide stepless speed regulation. Outstanding in working efficiency, operating stability and reliability,
6. This Tower Crane equipped with hydraulic lifting and connecting. This Tower Crane' s height can accordign to the actual height of the building and at the same time unchange the lifting capacity.
7. LVF: Frequency control, variable speed, smoothness and high stability, non-striking.
8. SM: Three-speed change pole motor, simple in structure, economical ,fitting.

- Q: I would like to get some advice from Martial artists of the training that Crane style Kung Fu go trough especially the balance. I would like to learn how they learn to balance without difficulty and the training they go trough.
- I don't train in Crane style Kung Fu but I can give you some balance training tips. 1. Stand on one leg whenever possible (doing the dishes, waiting in line, etc.) 2. Walk on a Balance Beam (a wall, a line on the floor, a large long block, etc. can all be used as a balance beam), just walk heel to toe and work on staying balanced. When walking becomes too easy try practicing kicks on the beam, then spinning kicks, then jumping kicks (NOTE: if your balance beam is off the floor make sure you have a spotter when you do any jumping or spinning) 3. Practice, practice, practice Ask your instructor for more exersizes internet videos can be good but are unreliable and dangerous in the hands of people who don't know what they are doing.
- Q: I understand the Crane stances and know there are more than one. I am referring to the single leg crane stance. I also know that stances are only used briefly. But I am curious, does this stance have any bunkai applications? Or is it only useful against dodging a kick or preparing to kick?
- Great question. This is one of those stances that I believe can be more static in nature. I think this stance, as Kokoro points out, is a great example of a lying-on-the-floor technique without actually having to lie on the floor. There are 3 kinds of crane stances, that I'me aware of: 1) the left foot is placed behind the right knee and the left foot's shin is perpendicular to the floor 2) the left foot is placed next to right knee and the left foot's shin is perpendicular to the floor 3) the left foot is placed next to right knee and the left foot's shin is ANGLED (sticks out to the left) to the floor in method 1), the application can represent a bind, hook, or pull toward you, of opponet's knee/shin while standing or lying down. in method 2), the there are a couple of applications: 2a) it is a on-the-floor position where you are mounted; your knee up represents keeping the distance open between you and opponent. 2b) it is a chamber of sorts to a jumping front snap kick (some call this a crane kick, which was a question that was asked about this a day or two ago) - and Shadam mentions this again in this question 2c) it is a check or block of a kick or weapon, as Liondancer mentions. in method 3), the application represents that your opponent is kicked to the inside of the knee: either to disable or to sweep.
- Q: Is boom truck a crane truck? Are they the same or two different kind of truck?
- A 'boom' is attached to a flat-bed truck and is used to unload a heavy delivery (usually building supplies and materials) to a specific location. A 'crane' is similar except that it doesn't unload things. It is attached to a truck and is used for moving heavy objects and materials from one place on another on the same property.
- Q: What is the calibration value of a tower crane?
- Three, gravity moment MThe product of amplitude L and the corresponding lifting objects called Q gravity lifting moment, the unit is kN - M.Tower crane capacity is based on lifting moment representation. It uses the product of the maximum working range and the corresponding maximum lifting load as the calibration value of the lifting moment.Four 、 lifting height HIt refers to the vertical distance from the surface to the parking level of the crane sling allows the highest position. The unit is m.Five, work speed1. lifting speed (down) Vn - stable state of motion, the vertical displacement velocity of the rated load. The unit is m/min.2. crane (CART) running speed of Vk, stable state of motion, the running speed of the crane. The operating speed of a crane with rated load on the horizontal (or horizontal rail) surface, at the height of 10m away from the ground, and when the wind speed is less than 3m/s.
- Q: What is the scrap standard of tower crane hook?
- The American Standard can provide for your reference:1, hook hanging points in the effective area of cross sectional wear more than 10%, should be disabled and scrapped.2 any visible permanent deformation and cracks shall be disabled and scrapped.3, if the wear is in the same area in two directions, it should be controlled within 5%.4, any hook opening deformation is not greater than 5%, or in accordance with the manufacturer's guidelines to determine.5, hook bow hook (i.e. intermediate position hook C shape) wear amount should be less than 5%.
- Q: Would David have made a better babysitter than a crane driver?

- they claim to have what you need. Good luck, I bet it's near impossable to get parts over there. You have a lot of work?
- Q: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?
- Use trigonometry, it's a triangle of forces.
