常用超重、吊裝、拖運(yùn)安全技術(shù)交底

一、 垂直運(yùn)輸架、吊盤裝置技術(shù)交底
垂直運(yùn)輸架擔(dān)負(fù)著腳手架上施工人員、工具和材料的垂直運(yùn)輸任務(wù)。目前使用的有：井架、龍門架、獨(dú)桿提升架等。井架和龍門架的吊盤均應(yīng)有可靠的安全裝置，防止吊盤在運(yùn)行中和停車裝、卸料時(shí)發(fā)生嚴(yán)重事故，吊盤安全裝置有：
１． 吊盤停車安全裝置是防止吊盤在裝、卸料時(shí)卷?yè)P(yáng)機(jī)制動(dòng)失靈而產(chǎn)生跌落事故的一種裝置，有安全支杠和安全掛鉤兩種形式。目前普遍使用的是安全支杠裝置，它由安全杠和安全卡兩部分組成。安全卡還具有使裝料、卸料平穩(wěn)、方便的作用。為確保安全生產(chǎn)，卷?yè)P(yáng)機(jī)的制動(dòng)器和吊盤停車安全支杠應(yīng)聯(lián)合使用，同時(shí)還應(yīng)注意統(tǒng)一指揮升降。
２． 吊盤鋼絲繩的安全裝置是由無縫鋼管內(nèi)裝鋼制的可伸縮“舌頭”組成。它的作用是在吊盤綱絲繩斷后的瞬間將“舌頭”彈出管內(nèi)，擱在井架或龍門架的橫桿上，以保證吊盤不致往下跌落。
二、 卷?yè)P(yáng)機(jī)安全技術(shù)交底
３． 建筑施工中卷?yè)P(yáng)機(jī)的安裝多為臨時(shí)安裝，利用機(jī)座上的預(yù)留孔或用鋼絲繩盤繞機(jī)座固定在地錨上。機(jī)座后部加放壓鐵，確保卷?yè)P(yáng)機(jī)在作業(yè)時(shí)不發(fā)生滑動(dòng)、位移、傾覆現(xiàn)象。
４． 鋼絲繩出頭應(yīng)從下方引出，卷筒中心應(yīng)與前面的第一個(gè)導(dǎo)向滑輪中心線垂直，第一個(gè)導(dǎo)向滑輪不準(zhǔn)使用開口滑輪，滑輪應(yīng)用地錨固定，不準(zhǔn)綁在垂直運(yùn)輸架上。
滑輪距卷?yè)P(yáng)機(jī)至少保持8～12米，超過3噸的卷?yè)P(yáng)機(jī)
Commonly overweight, lifting, towing safety Technology Details

First, the vertical transport planes, hanging plate device Technology Details
Vertical transport aircraft construction workers charged with scaffolding, tools and materials task of vertical transportation. Currently used are: derrick, gantry, single rod racks to upgrade. Derrick and the crane gantry disk should have a reliable safety device to prevent the hanging plate installed in the operation and parking, unloading a fatal accident, suspended disc safety devices are:
1. Hanging plate hanging parking safety devices to prevent the installation disk, when the hoist Zhidongshiling discharge fall accident caused by a device, a security and safety support bars linked to two forms. Now commonly used device is safe and support bar, which by the safety bar and the security card of two parts. Security card also has to make loading, unloading smooth and easy function. To ensure safety, winch and crane set parking brake safety support bars should be used in combination, should also pay attention to unity of command down.
2. Hanging plate rope safety device is built of steel by the seamless and scalable "tongue" of the composition. Its role is to set the key link in the hanging wire rope up the rear of the moment would be "tongue" pop-up pipe, derrick or gantry resting on the rail to ensure that suspended plate will not fall down.
Second, hoist safety Technology Details
3. Construction, installed in the winch for the temporary installation, use the reserved holes on the base unit or base wire coil fixed to the ground anchor on. Placing the rear base pressure of iron, to ensure the hoist does not occur when the slide in the operation, displacement, overturning phenomenon.
4. Speak out from under the wire leads, with the front roll center should be the first guide pulley center line perpendicular to the first driven pulley wheel openings are not allowed to use, applied to anchor the fixed pulley, the shelves are not allowed to tie in the vertical transport.
Pulley away from the hoist to keep at least 8 to 12 meters, more than three tons of the hoist
