The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

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!

Q: crane:300t lift 100t pad sizes:4.5x2 mtrs.ground bearing capacity required?: This depends on the angle of the lift and the distance away from centre of the crane. With the lift at tipping range all 400t will be distributed along the outer half of the pad or on the extreme legs. Rule of thumb is all the load is placed under the one pad. so one pad is 9 sq metres and the load is 400 tonnes so the bearing capacity must exceeds 400/9 tonnes per square metre. 44.44444t/m^2

Q: expane the parts of crane?: The spelling error is fatal: expane does not resemble anything that makes sense. At least two things are called a crane, one a machine and the other a bird. So you just need to rewrite your question so that it explains what you want clearly enough for somebody to look up an answer.

Q: How to build a strong paper crane?: Fact: paper is relatively strong when you pull on it, but when you push on it, it easily crumples. Build your crane out of several bars. Bars that are being pushed upon by the weight need to resist the crumpling. A good way to do this is to roll a sheet of paper into a tube form to make the bars. Bars that are only being pulled on don't need to be more than a sheet of paper. A frame cranes are simple to make: www.lni.wa /wisha/rules/generalsafety/images/24_d2_a-frame.gif

Q: I've heard of people making 1000 origami cranes as a wedding gift or decoration. I am making them as a gift for my sister-in-law and her husband, whose new baby is due next month. I'm up to 730, so I need to keep plugging away! My question is how should I display them? I've heard of putting them in a gallon jar. I was also thinking of making strings of 100. Do you put the string through the pointy part on the back? Can I arrange them into a mobile? Any ideas would be appreciated.: What the heck?! One thousand origami cranes?! Whoa! Your fingers must be sore, you poor thing! Good work! I could never have that patience and endurance. This is what to do. Pick a room - any room they use often, like a living room - and swathe the whole thing in white curtains and drapes and tablecloths. Then spread the cranes out. Artistically perch them on shelves and rim the couches with them and arrange them in circle and diamond patterns on the coffee table. Make the whole room a sea of origami cranes, and then put up a big sign in the middle: CONGRATULATIONS! Or you could make a pi?ata. When whacked, the pi?ata will explode into one thousand origami cranes. Or put them all in a bucket on the rim of a door that is slightly ajar. When they fling it open, the buckets will dump a tremendous shower of paper onto their heads! Attach a bucket to a rope so that the buckets don't clank onto their heads and hurt them.

Q: Its on of the biggest helicopters in 1952-1955 I just need any information via you, internet, or even blue prints!I highly doubt that blueprints are probably destroyed: It never really took off as it was quickly replaced by the CH-54 Tarhe, but here is what I found…

Q: What is an attached tower crane?: Its weight is 5 ~ 100kN, lifting radius of 3 ~ 35m (trolley), the lifting height is 160m, the maximum lifting torque of 1600kN - m, each with high 2.5m, the QT4 - 10 type crane lifting system comprises a lifting sleeve frame, long stroke hydraulic jack, bearing seat, lifting beam and a positioning pin. The cylinder block of the hydraulic jack is installed on the support seat at the bottom of the tower, and the lifting process can be divided into five steps.

Q: The Wayfarerby Stephen Crane The wayfarer, Perceiving the pathway to truth, Was struck with astonishment. It was thickly overgrown with weeds. Ha, he said, I see that none has passed here In a long time. Later he saw that each weed Was a singular knife. Well, he mumbled at last, Doubtless there are other roads.I understand that it is about a person taken the easy way out, but what other underlying meanings are there?: Here is an interpretation: 1. ...the pathway of truth...was thickly overgrown with weeds. The path to truth was overgrown. Crane is explaining that few people try to find truth. Instead, they are influenced by the ideas and opinions of others. 2. ...each weed was a singular knife. Truth is difficult to find. To find truth, you have to endure cultural torture. 3. 'Doubtless there are other roads. The wayfarer is not taking the easy way out. When he finds the path to truth, he contemplates whether or not to walk down the path. He sees the weeds. He sees the knifes. Then he thinks, should I go back home or walk down the path. He realizes that there is only one path to truth, and decides to walk down the path. The poem has a similar theme to Robert Frost's The Road Less Traveled. In that poem, the main character also shows reluctance in taking the less traveled path.
