Characteristics of Tower Crane
1)This tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.
2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected; The max. attached height can reach 180m.
3) 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 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.
4) The crane has complete set 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.
5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

- Q: what are the application of crane?
- To lift and handle heavy objects. Haven't you seen giant cranes lifting big containers ( having automobiles) from docks and placing them on ships?
- Q: when a tall building is under construction you alwase see cranes on top. well i would like to know 1. how they move them up as the buildung gets taller and 2nd after there done how do they get them down?
- They disassemble them
- Q: In the poem "The Wayfarer”, what is Crane's ironic comment on the pursuit of truth?
- I am a big fun of Rayban as well. I always buy from this site...
- Q: So how does tower cranes and cranes used in constructions make use of mechanical advantage exerted from simple machines such as pulleys and levers?In other words, how does a crane use pulleys and levers?
- a crane has a pulley in order to reduce the workload. Each time there is a loop of the pulley made the workload is reduced.
- Q: I was looking at the glidecam hd1000 for my canon vixia hv40, but now I think I'm more interested in a crane (jib).I was thinking of the advance digital 6 ft. crane. I would replace some of the plastic parts for metal.I'll be using it to film sketches and short films. (my budget is 350 dollars, but id like it to be under that)the crane is 200 dollarsthe glidecam is 370 dollars (on amazon)Thanks,Mike
- It okorder / I have purchased Studio Jib last year and since then it is performing pretty good. It is quite light in weight that it can be carried very easily without any problem.
- Q: Under what circumstances are winches used and under what circumstances tower cranes are used?
- First of all, what you say should be a derrick or a Longmen frame. In any case, the derrick or tower crane should first meet the construction requirements, then the economy and safety requirements. To meet the construction requirements, it is much better to choose the derrick, of course, economically and safely. Derrick is a simple nonstandard equipment. It is easy to install, use and disassemble. It has low running cost and less safety risk than tower crane. The derrick is suitable for construction under 30 meters or less, especially for multi storied buildings and single pieces. The volume and quality are not more than 2 tons.
- Q: Is the first entry into the construction project? Or direct access to fixed assets?
- First in construction project. When the installation is completed, when it is ready to use, transfer to fixed assets account and make depreciation
- Q: how to build a crane using:woodelasticsgluescrews/boltsbottlessyringesnailsplastictin canand rubber tubingplease be detailed,thanks! :)
- Carefully. okorder has kit numbers and downloadable instructions for many Lego cranes. You might be able to find some of them on OKorder. You may not need to actually build the Lego crane. Instead, look at the model, determine the major pieces (wheels, turntable, arm, etc.). Then, look at your bundle of pieces and make something with the same function.
- Q: The crane was commissioned in the plant some 15 yrs back. The cranes is being used for lifting hot metal (iron) from furnace to Pig casting machine since commissioning. Regular maintenance is being done on the same.
- no you have to asses the related struturals.
- Q: im doing a project and i need to know what eats sandhill cranes asap.
- Predators of the sandhill crane include man, feral dogs, wolves, and coyotes (Canidae), crows and ravens (Corvidae), hawks and eagles (Accipitridae), jaegers (Stercorarius spp.), raccoon (Procyon lotor), alligator (Alligator mississippiens), bobcat (Felis rufus), black bear (Ursus americanus), river otter (Lutra canadensis), and snakes
