注意事项
（1）每台起重机必须在明显的地方挂上额定起重量的标牌。
（2）工作中，桥架上不许有人或用吊钩运送人。
（3）无操作证和酒后都不许驾驶起重机。
（4）操作中必须精神集中、不许谈话、吸烟或做无关的事情。
（5）车上要清洁干净；不许乱放设备、工具、易燃品、易爆品和危险品。
（6）起重机不允许超荷使用。
（7）下列情况不许起吊：捆绑不牢；机件超负荷；信号不明；斜拉；埋或冻在地里的物件；被吊物件上有人；没有安全保护措施的易燃品、易爆器和危险品；过满的液体物品；钢丝绳不符合安全使用要求；升降机构有故障。
（8）起重机在没有障碍物的线路上运行时，吊钩或吊具以及吊物底面，必须离地面2m以上。如果越过障碍物时，须超过障碍物0.5m高。
（9）对吊运小于额定起重量50%的物件，允许两个机构同时动作；吊大于额定起重量50%的物件，则只可以一个机构动作。
（10）具有主、副钩的桥式起重机，不要同时上升或下降主、副钩（特殊例外）。
（11）不许在被吊起的物件上施焊或锤击及在物件下面工作（有支撑时可以）。
（12）必须在停电后，并在电门上挂有停电作业的标志时，方可做检查或进行维修工作。如必须带电作业时，须有安全措施保护，并设有专人照管。
（13）不许随便从车上往下乱扔东西。

（20）起重机不允许互相碰撞，更不允许利用一台起重机去推动另一台起重机进行工作。
（21）吊运较重的物件、液态金属、易爆及危险品时，必须先缓慢地起吊离地面100~200mm，试验制动器的可靠性。
（22）修理和检查用的照明灯，其电压必须在36V以下。
（23）桥式起重机所有的电气设备外壳均应接地。如小车轨道不是焊接在主梁上时，应采取焊接地线措施。接地线可用截面积大于75mm2的镀锌扁铁或10mm2的裸铜线或大于30mm2的镀锌圆钢。司机室或起重机体的接地位置应多于两处。起重机上任何一点到电源中性点间的接地电阻，均应小于4Ω。

（24）要定期做安全技术检查，做好预检预修工作。

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.
