First, crane tube common faults and solutions
1. When the crane tube rotates, it feels heavy on one side and light on the other. Why?
This is because the installation flange is not horizontal, the crane pipe to the direction of the low flange rotation, it feels relaxed, to the direction of the height of the flange rotation, it feels heavier. You can remove the crane pipe, correct the flange, and then reinstall the crane pipe during maintenance.
2, disassembling crane pipe, should pay attention to what?
When removing the crane tube, the first thing to pay attention to is to remove the balancer. The balancer is packaged with a compressed spring, and if it is not removed first, it will easily hurt people or damage the crane pipe because of the force of the spring.
3. Can the balance of the crane be adjusted?
It can be adjusted. Please remove the rubber tail cover of the balancer, insert the special adjusting wrench, turn right to tighten, turn left to loosen, until satisfied. When adjusting, the crane tube is slightly raised to reduce the compression of the spring and save effort when adjusting.
4, crane tube sealing ring need how many spare parts is appropriate?
In general, a small number of can be prepared, because if the seal is not used for a long time, it will age.
5. What is the reason why the rotary joint will leak?
The important part of the crane pipe is the rotary joint, if the leak to analyze its specific reasons.
(1) Seal damage: leakage below the rotary joint may be a problem with the seal, because the seal will cause damage if it is operated for a long time or the medium is corrosive, and the seal can be replaced.
(2) Rotary joint surface wear: If there is no effect after the replacement of the main seal, it will still leak, then it is necessary to consider whether it is the rotary joint surface damage, such as scratches or accuracy problems. Then we need to replace the swivel.
(3) Grease leakage: Sometimes some liquid will leak in the middle of the rotary joint, which may be too much grease in the rotary joint leading to leakage, directly wipe clean.
Two, crane pipe repair and maintenance of the common content
In the process of use, it is necessary to maintain and maintain regularly in order to ensure the maximum service life of the crane pipe. The repair and maintenance of crane pipe is an important link to ensure the normal operation and prolong the service life of crane pipe. The following are the common contents of crane pipe repair and maintenance:
1, cleaning: regularly clean the crane tube, you can use a soft cloth or sponge dipped in the appropriate amount of detergent to wipe the crane tube surface, remove dust and stains. Be careful not to use corrosive or organic solvents.
2, lubrication: crane pipe needs to be regularly lubricated to reduce friction and wear. You can use a special crane pipe lubricant, apply it to the crane pipe, and then wipe it clean with a clean cloth.
3, check the connection: regularly check the crane pipe and other equipment connection is loose, if found loose, should be tightened in time.
4, check the sealing: check the sealing performance of the crane pipe to ensure that there is no air leakage or oil leakage. If any problem is found, the seal should be replaced in time.
5, check the pipeline: regularly check the crane pipe pipeline is blocked or damaged, if there is a problem should be cleaned or replaced in time.
6, pay attention to safety: when carrying out repair and maintenance, you must pay attention to safety to avoid accidental injury. Personal protective equipment such as gloves and goggles can be worn.
