1. The most important thing in the basic operation of the tower crane is the start and stop arm of the tower crane, acceleration and deceleration should be uniform, the key is when to stop the unstable can be stopped, the general boom when the hook swings to the direction of the cab to slow down and stop, to the driver's license to turn the arm in the opposite direction when the gear change acceleration. How to quickly stabilize the hook of the tower crane?
2. In the operation of the tower crane, the main thing is to accelerate gear-by-gear, decelerate gear-by-gear, and do not overstep the operation! 2 to 3 seconds between each shift; Secondly, we must learn to follow the car, just like we use the wire pendant, use the inertia, and you will understand. When the hook is thrown forward, it is forward, but the length of the distance with the master of depreciation needs to open the tower crane friends to understand the running speed of the trolley, of course, the time is long, practice makes perfect.
3. If the tower crane is opened, will you feel that the boom is still swinging in that direction when the rotating boom suddenly stops? In this case, you can empty the block, and then turn the big arm back to the opposite direction, and then vacate it, the technique should be fast, practice makes perfect.

Frequency conversion is a high-end cargo million crane, it is estimated that you are talking about resistance, frequency conversion is no gear can not be reversed operation, he is driven by digital electricity, let go and stop. The resistance crane is the Volkswagen crane, and the correct way to open is to start in 2nd gear and stop for one and a half seconds, and return to the first gear in second gear and add to the second gear and third gear. When parking, the first gear is reversed, and you can't stand in the second gear, don't be stuffy, this is a big taboo, and some three guns are blind.
This method can be used to idle without wind, and the lifting weight starts in first gear, and I see that the big arm is not moving.

1. In fact, the operation of the tower crane is very simple, the right hand is to control the landing hook, the left hand is to control the rotating boom and the running trolley, the landing hook is very simple, there is nothing to talk about, and the forward is the hook. This tower crane has only three gears, one, two, and three, and the back is the hook, so that the hook rises, and it is also three gears.
2. The left hand controls the rotation of the boom and the direction of the trolley. To the right is to rotate to the right, to the left is to rotate to the left, some tower cranes have four gears, some have three gears, as for the rotation of the arm to stabilize the left and right hooks, I don't know how to express it in words, generally when the hook to the left, I follow to the left, see the arm and the hook perpendicular when the arm stabilizes, if the hook is still swinging to the right, then the arm follows to the right, basically like this, but when it opens, it generally does not shake left and right, even if there is a little shaking, But when the big arm stops, the hook will not shake.
1. Using inertia, when the hook is thrown forward, it is towards the forward, and the length of the distance to be mastered requires understanding the running speed of the trolley.
2. If the front and back swing is very strong, you can try to push the trolley operating lever to the back, and then immediately vacate it, then push it to the front, and then vacate it, and so on, and it is also very effective.
3. If the tower crane is opened, if the boom is still swinging in that direction when the rotating boom suddenly stops, you can vacate the block, and then return the boom to the opposite direction to a block, and then vacate it.
In fact, the operation of the tower crane is very simple, I take the tower crane I opened as an example, I basically drive the small four zero, as for some other tall tower cranes I don't know, if you know a friend welcome to leave a message with me, we discuss together, I also hope to learn more knowledge.
That's what I drive.
The tower crane I drove has two operating levers (as shown below), the right hand is to control the landing hook, the left hand is to control the rotation of Chi Chun's boom and the running trolley, the landing hook is very simple, there is nothing to talk about, and it is the hook to go forward. My tower crane only has three gears, one, two, and three, and then there is the hook, so that the hook rises, and it is also three gears.
That's what it looks like
The left hand controls the rotation of the boom and the direction of the trolley. To the right is to rotate to the right, to the left is to rotate to the left, some tower cranes have four gears, some have three gears, as for the rotation of the arm to stabilize the left and right hooks, I don't know how to express it in words, I generally when the hook to the left I follow to the left, see the arm and the hook perpendicular when the arm stabilizes the arm, if the hook is still swinging to the right, then the arm follows to the right, I am basically like this, but I generally do not shake left and right when I drive, even if there is a little shaking, But the hook doesn't wobble when my big arm stops.

Hello, inverter tower crane.
It is basically the same as the operation mode of ordinary tower cranes, except that the frequency conversion rotation is forbidden to return. The operator must undergo professional training, obtain the tower crane operation certificate issued by the national construction department, and must also hold the certificate.
1. The commander of the tower crane must be certified to work, and the operation should be closely coordinated with the balance operator. Operators must also hold a certificate to work, and the signal of the commander should be strictly implemented during the operation, if the signal is unclear or wrong, the operator should refuse to execute. If an accident is caused by a command error, the commander shall be responsible.
2. When the tower crane far from the ground in the control room is difficult to command, two commanders can be set up at high altitude and on the ground, or walkie-talkie can be used.
and other effective contact methods for command.
3. Trolley luffing and boom luffing limiter and walking limiter of tower crane.
Torque limiters, hook height limiters and various travel limit switches.
and other safety protection devices, which must be complete, sensitive and reliable, and shall not be adjusted and dismantled at will. It is strictly forbidden to replace the control mechanism with a limiting device.
4. When the tower crane is operating, it is strictly forbidden for anyone to stay, work or pass under the crane arm and heavy objects. When heavy objects are lifted, it is strictly forbidden to pass above people. It is strictly forbidden to use tower cranes to transport personnel.
5. The tower crane machinery must operate according to the specified tower crane lifting performance, and shall not overload and lift objects of unknown weight. In special circumstances, when overload is required, it must be checked and safeguarded, approved by the technical person in charge of the enterprise, and supervised by a special person on site before lifting, but not more than 10% of the load limit.
6. It is strictly forbidden to lift heavy objects to hang in the air for a long time, and in case of sudden failure during operation, measures should be taken to drop the heavy objects to a safe place, and turn off the motor or cut off the power supply for maintenance. In the event of a sudden power outage, all controllers should be immediately dialed to the zero position, the main power switch should be disconnected, and measures should be taken to safely lower the heavy object to the ground.
7. It is strictly forbidden to use tower cranes for cable-lifting, oblique lifting and lifting heavy objects buried underground or condensed on the ground.
The concrete components or formwork that are poured on site must be loosened before they can be lifted. When lifting heavy objects, they should be tied smoothly and firmly, and sporadic objects should not be stacked or hung on heavy objects. Scattered materials and objects must be tied firmly with a cage or wire rope before they can be lifted.
Objects marked with binding positions or marks should be tied according to the marked positions. The angle between the binding wire rope and the object shall not be less than 300°.
9. In case of severe weather such as strong winds or heavy rain, heavy snow, fog and so on.
, the tower crane should be stopped in the open air. When working after rain and snow or in rain and snow, it should be tested first to confirm that the brake is sensitive and reliable before operation.
10. When the lifting load reaches 90% or more of the rated lifting capacity of the tower crane, the heavy object should be lifted 20 50cm from the ground to stop lifting for the following checks: the stability of the crane, the reliability of the brake, the stability of the heavy object, and the firmness of the lashing.

Dear, we are inquiring about the relevant information for you, please wait for a while.
Questions. How do you open it and float in the wind?
What does it mean to drift with the wind, which literally means to move with the wind?
1. In fact, the operation of the tower crane is very simple, the right hand is to control the landing hook, the left hand is to control the rotating boom and the running trolley, the landing hook is very simple, there is nothing to talk about, and the forward is the hook. This tower crane has only three gears, one gear, two gears and three gears, and then the hook is raised, so that the hook rises, and the slag is also sold quietly in three gears.
2. The left hand controls the rotation of the boom and the direction of the trolley. To the right is to rotate the ridge to the right, to the left is to rotate to the left, some tower cranes have four gears, some have three gears, as for the rotation of the arm to stabilize the left and right hook of the hand to judge the infiltration, I don't know how to express it in words, generally when the hook to the left when I follow to the left, see the arm and the hook perpendicular when the arm stabilizes the arm, if the hook is still swinging to the right, then the arm follows to the right, basically like this, but when it opens, it generally does not shake left and right, even if there is a little shaking, But the hook doesn't wobble when the big arm stops.
Questions. It is how to open it with the wind is the meaning of moving with the wind.
What you said is that there is no operation, turn off the power of the machine and float with the wind!
Questions. No.
How to open the inverter 6015 manually?
Otherwise, the plot is still locked.
Not really! The inverter is not a gear that cannot be operated in reverse, he is driven by digital electricity, and he stops when he lets go.
Neutral operation of the handle is stopped.
I don't know much about the knowledge of inverter tower cranes, I'm sorry I can't help you, you can consult your previous master or teacher who learned tower cranes.

How to open the tower crane, this is difficult to say, this is trained by special operators.
The constant frequency means that the motor (driving the reducer) has only one speed; After frequency conversion, it can be slowed down by various silver lead types, but not faster than constant frequency. The neutral operation handle is to stop, if it is not at the same frequency, such as pushing is open, then the frequency conversion is to push less and the speed is slow, and the speed of pushing more is fast. That's the difference.

Summary. The reasons for the failure of the tower crane hoisting inverter: 1. The high-speed limit control line is virtually connected; 2. Torque limit early warning and control action; 3. The overweight speed change switch of the force measuring ring is malfunctioning or the line is empty; 4. The contact between the interlocking contacts of high-speed and low-speed control lines is not real.
What about people. The reasons for the failure of the inverter when the tower crane is lifted: 1. The high-speed limit control line is virtually connected; 2. Torque limit early warning and control action; 3. The overweight speed change switch of the force measuring Sun bend selling ring is malfunctioning or the line is empty; 4. The interlocking contacts of high-speed and low-speed control lines are wide and unreal.
The reasons for the failure of the Taminling rough hoist inverter: (1) The wiring of the control line is wrong. Workaround:
Nuclear wiring diagram. (2) The fuse burns out. Workaround:
Check whether the fuse capacity is too small, such as replacing a large one. (3) Short circuit, grounding and open circuit of the windings of the electric mumu machine. Workaround:
Find out the short circuit and open circuit part and repair it. (4) The motor voltage is too low. Workaround:
Measure the grid voltage. (5) Winding wiring error. Workaround:
Check whether the brake voltage and windings are open or stuck. (6) The brake is not released. (7) The load is too large or the transmission machinery is faulty.
Reasons for the failure of tower crane lifting inverter: 1The motor is damaged.
If the motor of the fan is damaged, we can simply replace the motor. 2.Capacitor damage.
If the capacitor is damaged, contact a professional maintenance personnel for repair. The processing method is as follows:1
Check the operating status of the inverter after removing the motor line; 2.If the thread is removed and runs normally for a long time, it is generally a problem with the peripherals. Check the three-phase insulation and ground insulation of the cable and the motor of the cable; 3.
However, it is not excluded that it is a problem when the inverter is loaded after power-on; 4.Check the fault of the inverter itself, it may be a fault of the internal detection circuit or module of the inverter.

What is the correct way to stop the boom of the inverter tower crane? Hello dear, <>1When grasping the direction, when the general boom rotates the arm, the hook should slow down to stop when swinging in the direction of the cab, and change gears to accelerate when swinging in the opposite direction of the cab rotating arm.
2 9 Methods Step 22Pay attention to the speed of the boom when starting and stopping the acceleration and deceleration should be uniform, it is best to accelerate gear-by-gear, decelerate gear-by-gear, and never over-gear operation. 3 9 Methods Step 33
When the hook is thrown forward, it is forward, and the length of the distance is mastered, which requires the bureau to be proficient in the running speed of the trolley. 4 9 Methods Step 44Practice makes perfect when the arm suddenly stops, you may feel that the arm is still swinging in that direction, in this case, you can vacate the gear, and then return the big tong arm to the opposite direction of a gear, and then vacate it, do these techniques quickly, and practice makes perfect after a long time.
5 9 Methods Step 55If you want to drive a good car, you still have to master some basic common sense, if you don't even know the basic common sense, even your own safety may not be guaranteed. 6 9 Methods Step 66
Observe the weather If the weather is bad and the wind may be a little strong, it is very difficult to stop the big arm, you must have skilled technology, of course, if it is in the case of strong winds, the tower crane is not allowed to work. 7 9 Methods Step 77If the instability may be caused by the hook shaking from side to side, then the big arm can be adjusted according to the direction of the hook's swing, and the heel can be stabilized.
