In view of the fact that door cranes are largely assembled outdoors, maintenance and maintenance of cranes are often required, given that they are often exposed to sun and sunstorms, that the main works and components of the door cranes are destroyed or disfigured as a result of erosion, and that the associated electronic components and machinery are also very susceptible to ageing, which not only affects the efficiency of the crane's work but is more likely to cause ** a production accident。
Maintenance of 1 crane structure
The working characteristics and useful life of the crane units are very high in terms of routing. * first, the lifting hooks and zinc-coated wire ropes of the lifting equipment are examined to see if there can be fractures, cracks, relatively severe erosion, and it is cleaned and fertilized. On the other hand, every month, the wheel, wire rollers and sliders are checked to determine whether there are cracks and whether the bolts of the nailed foot and steel rollers are tightened. When the steel line is 5 per cent above or below the level of damage to the cylinders, it should be replaced; in the case of 8 per cent damage to the wheel wall and 25 per cent of the common diameter of the zinc-plated wire rope, the wheel wall should be replaced. In addition, the foot bolts of the speed-reducing machines are often checked for clear tightening。
Traditional organizational maintenance of 2 cranes
In maintaining and maintaining the port cranes, attention is to be paid to the detection of electrical motives, avoiding water seepage or ingestion during rotation, while ensuring that the electrical motor outlets and the end of the connection are waterproof, as well as to ensuring that the generators are applied to a switch source of 85 per cent of the excess rated current. Every season alternately, lubricant is replaced by hl30 oil in general for summer and hl20 oil in winter. It is important to note in this process that speed-reducing devices often have oil seepage conditions, so that, in the case of motor-reducing engines, it is necessary to ensure that they are properly sealed, while at the same time they are properly operated to prevent excess oil and non-stabilization of the rest of the oil, * it is reasonable to prevent impregnation if the gas-replacement equipment is placed in the vent to maintain the external environmental pressure balance of the brakes. In addition, there is a need to determine whether the hulls are punctuated by a hammer, and also to examine the face of tyre flipping at a level that does not reach 10 per cent, the edge of the hulls cannot reach 55 per cent, the proportion of the revolving axle is different, not exceeding 0. 1 per cent of the outer diameter, or, if that exceeds, the adjustment or replacement。
Maintenance of 3 crane tracks
In the maintenance of crane tracks, hammer knocks are also often used to verify whether the trajectory and the fixed bolts of the orbit are fractured and released. In addition, northern cities, where cranes are maintained, often remove snow from the tracks and avoid the erosion or rusting of the tracks. Each year, a test is carried out on the trajectory of the lifting equipment to ensure that the immediate trajectories do not easily exceed 3 mm and the relative altitude does not exceed 3 mm, and to determine, based on the findings of the detection data information, whether the trajectories are moving down。
4. Repair and maintenance of metal structures
* detailed screening of the specific bearings of cranes is required, as they are highly susceptible to destruction because of their concentration, such as the part of the foot that connects the steel beam, the part of the angular bearing of the base heavy beam, and the part of the foot that connects the beams. In addition, since metal structures are often exposed to outdoors, they must be protected from rust every year and painted with new paints, which can effectively increase the life of metal structures. At the same time, if the level of erosion of metal structures is 10 per cent, it will be treated with end-of-life treatment, and if the heavy beam is 1 per cent apart, it will be possible to try to repair or, if not destroy it. What?
5. Maintenance of electrical components and routes
In the case of maintenance of electrical metaware and routing, electrical switches are to be cleaned up at any time and in any place to ensure good contact with the route and to prevent short circuit failure from jeopardizing the normal operation of the lifting equipment. With more frequent communication contacts and immediate exposure to the output power of the lifting equipment, it is important to ensure that it is flattened and cleaned up so that it is easier and more scalable; at the same time, it is necessary to clarify that the crane control panel is clearly visible, operationally operational and operationally more scalable; and, in addition, to ensure that there is a regular connection between the crane's electric crane and the electrical control equipment, and that the on-site bolts of the electrical control equipment are tightened and that problems are promptly dismantled. *in the end, cable metal pipes for lifting equipment will be checked from time to time to see if there is a state of rust and to paint them so as to avoid an expansion of the level of erosion.* it is good to have a relatively waterproof response to prevent the emergence of the leachate, which is only likely。
6 other crane maintenance and maintenance requested
Since cranes are large-scale mechanical equipment that is used on a regular basis, the condition of a variety of restricted devices is checked during routine maintenance and maintenance to ensure that they can remain stable in operation; at the same time, ensuring the integrity of the crane partitions and ** protection plates is a reasonable way of maintaining the lives of operators** and therefore must be given higher priority; in addition, there is a need to ensure the stability of the various **carlights, which are essential to ensuring normal performance at work and provide good conditions for maintenance and maintenance, and are more efficient in lifting cranes。
In general, in order to improve the efficiency of cranes and to maintain the lives of operators,** high priority should be given to the maintenance and maintenance of cranes, and reasonable maintenance and maintenance responses should be carried out on a regular basis; in addition, strict compliance with the standard operating procedures of cranes is required to avoid accidents to the greatest extent possible and to increase the useful life of cranes。
