在(zai)(zai)板(ban)(ban)坯(pi)(pi)(pi)夾鉗(qian)(qian)裝置(zhi)中(zhong),這種(zhong)夾鉗(qian)(qian)裝置(zhi)的(de)結構最簡單,自重最輕,造價也最便(bian)宜;因為沒有動力裝置(zhi),小車上(shang)不需設置(zhi)電纜卷(juan)筒;可以夾取高溫的(de)板(ban)(ban)坯(pi)(pi)(pi),這是它的(de)優點.其(qi)缺點是:工(gong)作效(xiao)率較(jiao)低;沒有夾鉗(qian)(qian)的(de)開度及板(ban)(ban)坯(pi)(pi)(pi)厚度的(de)指示裝置(zhi),因此需地面工(gong)人配(pei)合操(cao)作;同時,一種(zhong)鉗(qian)(qian)口深度的(de)夾鉗(qian)(qian)只能(neng)適用于一定(ding)的(de)高度——單塊板(ban)(ban)坯(pi)(pi)(pi)的(de)厚度或(huo)幾塊板(ban)(ban)坯(pi)(pi)(pi)的(de)總高一的(de)板(ban)(ban)坯(pi)(pi)(pi).在(zai)(zai)需夾取不同高度的(de)板(ban)(ban)坯(pi)(pi)(pi)時需更換不同的(de)夾鉗(qian)(qian)或(huo)人工(gong)調(diao)整
