4、操作注意事項
4.1、送電前，檢查各控制器應停在零位，各開關位置正確?？刂乒裆细鳈C構斷路器閉合，欄桿門關好。
4.2、按送電按鈕，電源送電，觀察各電氣元件是否有異?，F象，確定無誤后方可操作各機構。
4.3、起升機構及大小車控制采用控制器控制，操作要求與普通天車相同。
4.4、對于起升機構的制動器要每班檢查，運行機構的制動器2-3天檢查一次，發現問題要及時調整維修。
5、抓斗的操作
5.1、抓斗張開操作：把起升與開閉同時下降到適當位置，停止起升下降，開閉繼續下降，抓斗逐漸張開，完成張開動作。
5.2、抓斗閉合操作：開閉卷筒作起升操作，抓斗上部滑輪組不動，下部滑輪組作向上移動，到抓斗抓齒相互交叉相碰，抓斗的閉合動作完成。在閉合過程中，起升卷筒作適當的起升操作，使升降鋼絲繩不下垂為限。
5.3、抓斗的上升、下降操作：抓斗無論是張開或閉合狀態，均可作上升或下降操作。在操作時，升降與開閉卷筒必須同時進行。

Operating procedures
1 and the responsibilities of the driver
1.1, the operation of basic requirements: steady, accurate, fast, safe and reasonable.
1.2, familiar with the main parameters of the crane, purpose, equipment, operation and maintenance requirements.

1.4, crane in before each run, must be warned to drive signal.
1.5, the driver must work closely with the hook, moving in tandem. Moving and lifting heavy weights, should only listen to hook signals emitted from work, but the "stop" signal no matter who, all should stop immediately.
1.6, the controller should start step by step, in front of the body completely shut down, it is forbidden to direct controller from forward to reverse to reverse connect braking. In case of emergency, the controller can play in reverse gear used to brake.
1.7, skilled use of fire extinguishers.
2, the use of crane information
2.1, should by the crane operator to operate cranes.
2.2, the crane work, forbid anyone to stay on the crane.
, crane weight 2.3 runtime, must be at least 0.5 meters above the highest blockage on weights paths.

If the environment does not allow will be hanging down directly, can be repeated lifting, and start the big car choose good place to be hanging down, don't let it free fall.
2.9, the hoisting bucket, should make the hoisting rope with the opening and closing line speed is equal, in order to make wire rope force uniform.
2.10, are not allowed to use the grab the whole thing.
2.11, each shift work check grab before hanging ropes tighten situation, opening/closing rope wheel condition.
3, the end of the driver's job duties
3.1, grab crane after the completion of the work, will grab down the ground, shall not be suspended hanging.
3.2, stop to protect the total power switch in the cabinet.

Found in 3.4, crane running and check the problem and the handling of shall all be credited to handover manuals. At the same time to take over the driver log rear can leave the crane.
4, operating considerations
4.1, before sending, check the controller should stop at zero, the switch position is correct. Control agencies on closed circuit breaker, the rail door close.
4.2, according to the power button, power transmission, to observe the electrical components to see if there is abnormal phenomenon, determine the correct rear can operating agencies.
4.3, lifting mechanism, and a large car control controlled by controller, same as the common crane operation requirements.
4.4, for lifting mechanism brake check per shift, operation of the brake 2-3 days check again and find problems to adjust maintenance.
5, the operation of the grab bucket
5.1, grab open operation: the lifting with the opening and closing down to the appropriate location at the same time, stop lifting down, opening, continue to fall, grab gradually open, complete the open action.
5.2, grab a closed operation: open and close drum lifting operation, grab the upper pulley block, the lower pulley block move up, to grab grab teeth into overlapping, grab the closing of the action is complete. In the process of closing, the hoisting drum for proper lifting operation, make the elevator wire rope or not.
5.3, grab the rise and fall of operation: grab either open or closed state, can make up or down operation. In operation, lifting and reel should be carried out at the same time.
