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.

Q: ok. soooo.i've got this essay.and i'm stuck.all because i can't figure out the poetic form of War is Kind.help??its only the first five stanzas.Do not weep, maiden, for war is kind. Because your lover threw wild hands toward the sky And the affrighted steed ran on alone, Do not weep. War is kind. Hoarse, booming drums of the regiment, Little souls who thirst for fight, These men were born to drill and die. The unexplained glory flies above them, Great is the battle-god, great, and his kingdom -- A field where a thousand corpses lie. Do not weep, babe, for war is kind. Because your father tumbled in the yellow trenches, Raged at his breast, gulped and died, Do not weep. War is kind. Swift blazing flag of the regiment, Eagle with crest of red and gold, These men were born to drill and die. Point for them the virtue of slaughter, Make plain to them the excellence of killing And a field where a thousand corpses lie.???
War Is Kind Stephen Crane (1899) Do not weep, maiden, for war is kind, Because your lover threw wild hands toward the sky And the affrighted steed ran on alone, Do not weep. War is kind. Hoarse, booming drums of the regiment, Little souls who thirst for fight, These men were born to drill and die. The unexplained glory flies above them. Great is the battle-god, great, and his kingdom-- A field where a thousand corpses lie. Do not weep, babe, for war is kind. Because your father tumbles in the yellow trenches, Raged at his breast, gulped and died, Do not weep. War is kind. Swift blazing flag of the regiment, Eagle with crest of red and gold, These men were born to drill and die. Point for them the virtue of slaughter, Make plain to them the excellence of killing And a field where a thousand corpses lie. Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind!
