Ship lifting capacity, do you really know?

Ship lifting capacity, do you really know? 2019 - 12 - 11 Marine grams of the crane is a kind of frequently used cargo handling equipment, is widely used on board. Because of its complexity is very high mechanical equipment, in the event of failure, will cause the shipment delay, damage, loss and even casualties, and then to the owner's direct economic loss. While lifting capacity of failure are generally occur in the process of loading and unloading cargo, in order to ensure the normal operation of grams of lifting capacity, the crew to maintain good lifting equipment, make the moment is in good working condition. So, in the process of using g lifting capacity need to pay attention to what issues? The cause of grams to crane failure have? Let's take a look at. 。 。 First of all, should be done before lifting capacity in the use of basic safety inspection, including: 1, before using g the crane handling operation should be in the condition of slow no-load test and verify the safety protection devices within the range set action and protection; 2, confirm the pipe fittings and no leakage and loose, especially connecting hoses, if there is any loosening and leakage should be timely make necessary repair or change new, or is likely to lead to serious fall accident; 3, confirm the brake lifting, luffing brake solenoid valve movement, control oil, brake pad brake function is normal, and check the oil level before use keep it in the normal position, the main oil in the hydraulic system and control the oil filter should be regular inspection and cleaning; 4, in order to strengthen ventilated, cooling oil temperature, cooling fan damper before use must be in the open position, and the main motor has not started, the cooling fan is in a state of lock cannot be started. After the above checks, need to confirm the joystick is put in the neutral position, if the lever is not neutral position, the electric locking device will limit the main motor can't start. Confirm appropriate lever stroke switch position, otherwise the working current big easy trip and even burning motor. Only pay more attention to the maintenance of the equipment at ordinary times, before use to conduct a comprehensive inspection, to ensure to reduce the occurrence of failure in use. Through the survey found that led to the use of g to lift the cause of the malfunction, the typical basically has the following several! 1, steel wire rope, lifting capacity of the steel wire rope, here mainly refers to cargo runner and one thousand jins, due to overload, fatigue damage, aging and congenital defects, the influence of the sudden rupture, the hook suddenly fell from the sky, cause machine damage, damage and even loss of life. 2, slewing bearing refers to turning big gear ring, if its not the correct maintenance regulation, after reaching its damage limit, the lifting capacity will collapse, the consequences are disastrous. 3, the pulley to have multiple on hanging pulley, such as the tower pulley with the top of the upper pulley and boom. Pulley bearing must be periodically inject grease or what we commonly known as butter. But a lot of the ship's remote filling pump damage due to improper maintenance, so let's preview the pulley bearing the relevant personnel through the ropes and climbed up the ladder, time-consuming and laborious. So there will be many people no longer go to preview the pulley bearing, gradually bearing stuck due to lack of oil, and the pulley jammed or not smooth rotation will accelerate wire rope wear, resulting in mentioned in article 1 of failure. 4, irregularities shipping cargo, tend to be fuck hanging by the dockers. But many countries such as southeast Asia Africa and other countries of the dockers in tended to be rough crane operation, large swing left hanging on the goods, in the extreme cases can lead to structural collapse. So when loading and unloading of cargo, the crew must supervise the dockers fuck hanging way. Hydraulic grams of the crane is a kind of high technical content of electricity, liquid, machine integration of cargo ship equipment, in use process, needs the crew on the daily maintenance as required. And hydraulic pressure in the practical work, lifting capacity is often due to the lack of proper maintenance, improper operation, such as poor working environment and disrepair, cause high failure rate. Want so the equipment in the workplace don't fail, only through maintenance to reduce equipment failure rate. Must strictly implement maintenance plan, at ordinary times to g for regular inspection and maintenance, and every five years by the service provider or the related engineer to g to make a comprehensive inspection, including hydraulic pump, motor, etc. For hydraulic oil sample taken on a regular basis, through the analysis of the pollutants and the wear debris, to evaluate internal condition, in case of need to take corresponding measures, to ensure the personnel safety and efficient operation of the ship. （ Source: maritime services)
