注意事項
（1）每臺起重機必須在明顯的地方掛上額定起重量的標牌。
（2）工作中，橋架上不許有人或用吊鉤運送人。
（3）無操作證和酒后都不許駕駛起重機。
（4）操作中必須精神集中、不許談話、吸煙或做無關的事情。
（5）車上要清潔干凈；不許亂放設備、工具、易燃品、易爆品和危險品。
（6）起重機不允許超荷使用。
（7）下列情況不許起吊：捆綁不牢；機件超負荷；信號不明；斜拉；埋或凍在地里的物件；被吊物件上有人；沒有安全保護措施的易燃品、易爆器和危險品；過滿的液體物品；鋼絲繩不符合安全使用要求；升降機構有故障。
（8）起重機在沒有障礙物的線路上運行時，吊鉤或吊具以及吊物底面，必須離地面2m以上。如果越過障礙物時，須超過障礙物0.5m高。
（9）對吊運小于額定起重量50%的物件，允許兩個機構同時動作；吊大于額定起重量50%的物件，則只可以一個機構動作。
（10）具有主、副鉤的橋式起重機，不要同時上升或下降主、副鉤（特殊例外）。
（11）不許在被吊起的物件上施焊或錘擊及在物件下面工作（有支撐時可以）。
（12）必須在停電后，并在電門上掛有停電作業的標志時，方可做檢查或進行維修工作。如必須帶電作業時，須有安全措施保護，并設有專人照管。
（13）不許隨便從車上往下亂扔東西。
（14）限位開關和聯鎖保護裝置，要經常檢查。
（15）不允許用碰限位開關作為停車的辦法。
（16）升降制動器存在問題時，不允許升降重物。
（17）被吊物件不許在人或設備上空運行。
（18）對起重機某部進行焊接時，要專門設置地線，不準利用機身做地線。
（19）吊鉤處于下極限位置時，卷筒上必須保留有兩圈以上的安全繩圈。
（20）起重機不允許互相碰撞，更不允許利用一臺起重機去推動另一臺起重機進行工作。
（21）吊運較重的物件、液態金屬、易爆及危險品時，必須先緩慢地起吊離地面100~200mm，試驗制動器的可靠性。
（22）修理和檢查用的照明燈，其電壓必須在36V以下。
（23）橋式起重機所有的電氣設備外殼均應接地。如小車軌道不是焊接在主梁上時，應采取焊接地線措施。接地線可用截面積大于75mm2的鍍鋅扁鐵或10mm2的裸銅線或大于30mm2的鍍鋅圓鋼。司機室或起重機體的接地位置應多于兩處。起重機上任何一點到電源中性點間的接地電阻，均應小于4Ω。
（24）要定期做安全技術檢查，做好預檢預修工作。
Of the goods
Bridge crane
application
Bridge crane is the modern industrial production and lifting transportation realize mechanization, automation of production process in the important tools and equipment. So bridge crane in indoor and outdoor industrial and mining enterprises, steel chemical, railway transportation, ports and logistics departments and establishments are widely used.
Matters needing attention
(1) each crane must hang rated lifting weight sign in obvious places.
(2) work, bridge frame is not allowed to someone or use the hook carrier.
(3) no operation certificate and drunk are not allowed to drive the crane.
(4) in the operation must be focused, are not allowed to talk, smoking, or do not.
(5) the car should be clean; Don't mess with equipment, tools, inflammable, explosive goods and dangerous goods.
(6) are not allowed to hypercharged crane use.
(7) no lifting in the following circumstances: bind not firm; Overload the parts; The signal is unknown; Suspension; Buried or frozen items in the field; Suspended objects on someone; Without safety protection measures of inflammable, explosive and dangerous goods; A full liquid items; Do not conform to the requirements of the safe use of wire rope; Lifting mechanism is faulty.
Crane (8) in the absence of obstacles on a line running, hook or sling and material base, must be more than 2 m off the ground. If must over obstacles over obstacles, 0.5 m high.
(9) for lifting objects smaller than 50% of the rated lifting weight, allow the two institutions and actions; More than 50% of the rated lifting weight objects, then only can one agency action.
(10) has a main, secondary hook bridge crane, do not rise or fall at the same time, deputy hook (special exception).
(11) on the lift objects not welds or hammer and work under the objects (supported).
(12) must be after a power outage, and hung on the switch power assignment marks, just can do the inspection or maintenance work. When must live working, have security measures to protect, and is equipped with the specialist care.
(13) is not allowed to casually throw things down from the car.
(14) limit switch and interlock protection device, check regularly.
(15) are not allowed to touch the limit switch as a way to stop.
(16) when the hoist brake problems, are not allowed to lift heavy things.
(17) and suspended objects are not allowed to run over the people or equipment.
(18) to the portion of the crane during welding, to set up the ground, not allowed to use a fuselage for ground.
(19) hook in the limit position, drum must be retained more than two laps on the safety loops.
(20) crane is not allowed to collide with each other, more is not allowed to use a crane to promote another crane.
(21) lifting heavy objects, liquid metal, explosive and dangerous goods, must first slowly lifting from the ground 100 ~ 200 mm, test the reliability of the brake.
(22) repair and check with the floodlight, its voltage must be under 36 v.
(23) bridge crane can all electrical equipment enclosure. Such as trolley track is not welded on the main girder, welding ground measures should be taken. Ground wire available cross-sectional area was greater than 75 was galvanized flat iron or 10 bare copper wire or greater than 30 was galvanized round steel. Cab or lifting the body of the grounding position should be more than two. Crane on any point to the power between the neutral point grounding resistance, both should be less than 4 Ω.
(24) to do safety technical inspection regularly, to do preview work in ap.
