src="http://i4.qhimg.com/dr/200__/t01bee60058ece216be.jpg" />◇ 工作中鉗爪打滑，導(dǎo)致安全事故。</p><p>◇ 拉馬偏載，導(dǎo)致絲桿彎曲而卡進(jìn)中空油缸，進(jìn)退兩難。</p><p>◇ 拉馬偏載，導(dǎo)致絲桿、鉗爪折斷或拉直，引發(fā)安全事故。</p><p>◇ 油缸行程太短，需多次定位才能完成工作，無端增加工作量。</p><p>1978年，美國寶賽羅POSILOCK公司了安全籠式自鎖自對(duì)中拉馬，<strong>美國寶賽羅 POSILOCK</strong> 自鎖自對(duì)中液壓拉馬均配有帶彈簧回縮的大行程液壓油缸，使用時(shí)只要接上相應(yīng)的手動(dòng)泵或電動(dòng)泵，油缸的粗大結(jié)實(shí)的柱塞直接起到絲桿的作用，穩(wěn)固作用于被拉拔工件，從而能*避免上述問題，其主要特點(diǎn)有：</p><p><strong>◆</strong> *的安全籠設(shè)計(jì)，能*鎖定工件，防止打滑，工作更安全</p><p><strong>◆</strong>自動(dòng)對(duì)中，防止偏載，保證絲桿始終處于受力中心，延長使用壽命</p><p><strong>◆</strong>通過 T 型手柄和安全籠迅速控制拉馬，操作更方便</p><p><strong>◆</strong> 無絲桿設(shè)計(jì)，大行程油缸柱塞直接作用于被拉拔工件，操作更簡單，使用更安全</p><p><strong>◆</strong> 3/8NPT 快速接頭，可與各種 700bar/10000psi 級(jí)液壓系統(tǒng)配套使用</p><p><strong>◆</strong>
