注意事項

1、起吊重物時,吊鉤鋼絲繩應保持垂直,不準斜拖被吊物體?!?、所吊重物應找準重心,并捆扎牢固。有銳角的應用墊木墊好。
3、在重物未吊離地面前,起重機不得做回轉運動。
4、提升或降下重物時,速度要均勻平穩,避免速度急劇變化,造成重物在空中擺動,發生危險。落下重物時,速度不宜過快,以免落地時摔壞重物。
5、起重機在吊重情況下,盡量避免起落臂桿。必須在吊重情況下起落臂桿時,起重量不得超過規定重量的50%。
6、起重機在吊重情況下回轉時,應密切注意周圍是否有障礙物,若有障礙物應設法避開或清除。
7、起重機臂桿下不得有人員停留,并盡量避免人員通過。
8、兩臺起重機在同一軌道上作業,兩機間距離應大于3m。
9、兩臺起重機合吊一物體時,起重量不得超過兩臺總起重量的75%,兩臺起重機走行、吊放動作要一致。
10、起重、變幅鋼絲繩需每周檢查一次,并作好記錄,具體要求按起重鋼絲繩有關規定執行。
11、空車走行或回轉時,吊鉤要離地面2m以上。
12、風力超過六級時,應立即停止工作。TMK應將臂桿轉至順風方向并適當落低,將吊鉤掛牢。龍門吊須打好鐵楔(止軌器),并將吊鉤升至上限。同時關好門窗,切斷電源,拉好纜風繩。平時工作完畢后也應照此辦理。
13、起重機平臺上嚴禁堆放雜什物件,以防在運行中掉下傷人,經常用的工具應放在操作室內的專用工具箱內。
14、運行中,不準突然變速或開倒車,以免引起重物在空中擺動,也不準同時開動二項以上(包括副鉤)的操作機構。
15、開車時,操作人員的手不得離開控制器,運行中突然發生故障時,應采取措施將重物安全降落,然后切斷電源,進行修理。嚴禁在運行中檢修保養。
16、起重機遇有下列情況之一者不得起吊
1、重物超過起重機額定起重量。
2、重物重量不明。
3、信號不明。
4、重物捆扎不牢。
5、露天作業遇六級(梁上五級)以上大風及大雨、大霧等惡劣氣候。
6、夜間作業照明不好。
7、斜拉。

8、鋼絲繩嚴重磨損出現斷股及有人在起重機上或機房進行檢修。


Of the goods

Gantry crane (gantry crane) is the level of bridge is set in two forms door frame in the shape of a leg of a bridge type crane. This kind of crane in orbit on the ground, mainly used in outdoor storage yard, dock, station, port and railway station, handling and installation operations.

Matters needing attention

1, when lifting heavy objects, hook wire rope should be kept vertical, are not allowed to be inclined dragging suspended objects. 2, the hanging weight should get the center of gravity, and securely. Have acute applications stow-wood pad is good.

3, before the weight not hanging off the ground, crane shall not do rotary motion.

Four, ascending, or lower weight, and speed is steady, avoid rapid changes in speed, causing heavy swing in the air, produce risk. Falling weight, velocity shoulds not be too fast, lest broke when landing weight.

5, in the case of hoisting crane, avoid lift arm rod. Must be in the case of hoisting lift arm lever, lifting weight shall not exceed 50% of the weight.

6, in the case of hoisting crane slewing, should pay close attention to the surrounding obstacles, if there are obstacles should try to avoid or clear.

7, can not have staff under the crane arm, and try to avoid personnel through.

8, two crane operation on the same track, the distance between the two machines should be greater than 3 m.

9, two crane lifting an object, the weight must not exceed 75% of the total lifting weight, two two crane go line, sling the action should be consistent.

10, hoisting, luffing wire rope need to check once a week, and make records, specific requirements in accordance with the relevant regulations of the hoisting wire rope.

11, empty row or rotary hook to more than 2 m off the ground.

12, wind more than 6, should immediately stop working. TMK arm should be transferred to the wind and appropriately low, hanging hook. Gantry crane must play iron wedge (check rail), the hook and reach the ceiling. Shut the doors and Windows at the same time, cut off power supply, pull the cable wind rope. After work at ordinary times should be for.

13, crane platform are strictly prohibited to pile up miscellaneous things, to prevent falls off cuts in operating, and often use tools should be put inside operation of special tools in the box.

14 and run, not suddenly change or go against the trend, lest cause the weight of swing in the air, also are not allowed to be at the same time to start the two items of operating mechanism (including vice hook).

15, when driving, the hand of the operator shall not be allowed to leave the controller, a sudden failure in operation, measures should be taken to the heavy land safely, and then cut off power supply, repair. It is strictly prohibited in the operation of repair and maintenance.

16, lifting opportunities are one of the following circumstances shall not be lifting

1, the weight more than crane rated lifting weight.

2, heavy weights are unknown.

3, the signal is unknown.

4, heavy strapping not firm.

5, open-air homework in level 6 (5) on the beam above high winds and heavy rain, fog and other bad weather.
