Q:will this battery fit in an echo1 crane stock? (airsoft)?
crane stocks depend on the manufacturer.echo1 is the copy cat of Tokyo mauri but i have a echo1 m4 so yes it will fit.
Q:How much does it cost to build 18, 22, 35, 40, 50, 70, 100, and 120 ton cranes?
You would have to contact the crane manufacturer. Each size would have different cranes that meet that requirement, eg portable versus not portable. That's assuming those are total crane weight numbers? Or are they lifting capacities?
Q:Under what circumstances are winches used and under what circumstances tower cranes are used?
1, this depends on the specific construction organization design, the general height of less than 20 meters, all with the hoist.2, the framework of the structure, four, 18 meters, construction area, if large, with tower cranes, of course, labor-saving, time-saving and rapid progress, if the construction side agrees, it is best to use tower cranes.3, artificial wages are too high, the project is big, with the winch is not worthwhile, progress can not catch up, workers are also big grievances. The track type tower crane is usually used in shipyard or fixed freight yard.
Q:what would you wish for if you had 1000 paper cranes?
huh LoL
Q:how do they erect those huge cranes for constuction?
As described above, but the crane that is being used in our plant arrived in 80 semi truck loads!
Q:What is the email address for the cartoonist Brian Crane?
P)lease provide me the mailing address for Brian Crane. I desire to mail him a letter in reference to his Pickles comic strip. Thank you!
Q:how do construction crews put up a crane?
They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.
Q:What are the safety devices in a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.
Q:Materials to build a simple crane?

Q:how did charles darwin influence stephen cranes writing?
Influenced by Darwin’s Theory of Evolution, Crane believed that people’s actions were determined by environmental factors rather than by conscious choices on their part. He believed also that conflict was the crucible in which human development occurred, and thus was attracted to the violent and seamy aspects of human experience.
