展开全部需要32米和大于25吨吊车。因为吊车都是扛杆原理，力与力臂的关系，是动力乘方力臂等于阻力乘阻力臂的关系，在吊装物质时，会有好多的不确定因素，如场地环境，所以需要32米和大于25吨吊车会有一定的安全系数。',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign),e.getAttribute("jubao"))},getILeft:function(t,e){return t.left+e.offsetWidth/2-e.tip.offsetWidth/2},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#href\}\}/g,e).replace(/\{\{#jubao\}\}/g,n)}},baobiao:{triangularSign:"data-baobiao",tpl:'{{#baobiao_text}}',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign))},getILeft:function(t,e){return t.left-21},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#baobiao_text\}\}/g,e)}}};function l(t){return this.type=t.type

展开全部液压大吊车主杆分为5-6节，每节长度12-16米，还有副杆，长度8-10米。吊装作业主杆仰角度一般60-72度，如吊高62米，主杆出杆5节，每节按16米考虑，共出杆80米。吊重0.4吨，主杆仰角70度，吊高62米，需要吊重125吨以上液压起重机。已赞过已踩过你对这个回答的评价是？评论
收起130吨吊车忽略吊车臂杆重量和不考虑臂杆强度不足前提下的极限吊装能力简洁计算： 1、额定力矩：130吨（额定重量）*3米（额定重量的对应半径）=390吨米 2、18米半径极限载荷：390吨米/18米=21.67吨。 因此：如果考虑臂杆重量和...
