CMAX Tower Crane TC 7021 Construction Machine

Product Description:

Descriptions of our tower crane:

1, the topless tower crane reduce the dismounting requirements, lower weight, low mounting height, dismount each mast at a time in the air, save the labor cost, safety and fast.

2, it is suitable for crossover work of the cranes, without the tower cap and pull rod, the safety will be increased when there need the crossover work.

3, It is suitable for the special requirement about the height, such as airport nearby, tunnel, workshop ,and the construction site with high-tension cable.

4, It is suitable for the construction site that has the requirement about the crane boom, it can be used as internal climbing crane in the high-rise buildings, irregular roof or small areas.

5, It is very convenient for dismounting in the restricted construction site, dismount each crane boom at a time by manual.

6, The steel structure of crane boom has long using life and high safety standard.

7, The crane boom is good applicability, high-usage,the design of the topless tower crane boom is easy for realizing the serialization and standardization. Reduce the design and making cost.

8, Low design cost, short cycle, can much better satisfy the multiple demands of the customers.


Advantage of our tower crane:


1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.

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.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

3, boom stability is good, combination amplitude range.

4, suitable for height have special requirements occasions construction.

5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:How to win the skill crane?

Q:How to learn the training of Crane style Kung Fu balance?
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:Do crane flies bother people?
ANY type of bug bothers me. Especially the creepy crawlies. *shudders*. I wouldn't go to sleep if i knew i had a type of bug in my room. I guess you'll have to deal with them. Sorry. Good luck finding it.
Q:A crane uses 2 kW to raise a 100-kg box 20 meters. How much time does it take?
We start using by defining mechanical Power: = P=Work/time What is the work here? We lift the box a given distance. Work=mgh Since we know the power of the crane, we can simply plug in the values and solve for t: t=mgh/P This is only true if the crane has a constant power, which seems to be the case LeSmartOne
Q:What company makes good camshafts crower, comp or crane?
1. Crane did not go out of business although they were on shaky ground a year and a half ago. A group of private investors and corporations baled them out. Howard's, Crower Comp are all pretty equal. Your car has roller hydraulic lifters so you'd better know what you're buying. Your missing some Chevrolet factory roller lifters and roller cam grinds. I see you haven't purchased the 2010 GM Performance Parts Catalog from your Chevrolet dealer parts counter yet. It's loaded with mild to wild hydraulic roller small block cams. You haven't figured it out yeat have you? A cam switch isn't going to make that 305 run worth a hill of beans. You need a set of cylinder heads to alow it to breathe first. Remember the EQ 3045A vortec performance heads for your 305? The valves ports are bigger and shaped for higher velosity. You're so stubborn I know you'll buy a cam first and whine like hell cause the car won't run any better. You'd better give this project a lot of thought because you're stuck with the stock intake and fuel/air mixer. Lower rear end gears such as 3.42's or 3.73's will wake the car up. Do that first and see if you want to spend any more money on it.
Q:How do cranes get from one construction site to another without hitting streetlights, wires, car, buildings?
They are disassembled and carried via a truck to the next job site. Also some cranes are built into a truck and so they retract into itself and make it easier to get around in a city. Also in order to be a crane operator you have to have special certification and training. For the larger cranes that are able to be on the road, some times police departments well shut down roads in order for it to move around in the city.
Q:If a crane fly loses a leg...?
Only lizards can release a part of their body, but only the tail. It probably lost its leg while it was flying because it had a string tightly wrapped around it for a long time and it finally just fell off. It would probably hurt them a little because the bloodflow would be cut off and it would be somewhat numb.
Q:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
Should be the same series, but lifting weights are not the same
Q:how does a skyscraper crane use moments ?
OK... So what has your homework actually asked you to explain? Can you post the question...? There are moment forces going through a crane, is the aim of the homework simply for you to explain what a moment force is using a specific example ? A crane can be thought of in simple terms as a cantilever, ie one supported end and one free end, the lever arm force as it is sometimes referred to in schools is actually the moment force i.e. the moment for a crane with a boom L=40m long lifting a load of P=10kN would beP*L = 10*40 = 400 kNm, this is ignoring the self weight of the boom, if the boom weighed W=1.5kN/m (thats per meter, not to be confused with kNm which is kilo newton meters) then the moment generated by the self weight would be (WL^2)/2 = (1.5*40^2)/2 = 1200kNm so the total moment would be 1600kNm, so just remember for a point load the moment is force * distance from support ( in cantilevers) hope this helps... :)
