自由降落式救生艇保养检查 Maintenance and inspection
保养检查的周期与项目推荐如下：
Recommended maintenance period and items inbellows:
1、每周保养检查 Inspection and maintenanceweekly
1.1 对装置的各部分进行目视检查，保证装置始终处在立即可以进行救生艇自由降放的准备状态，如检查滑道上的导向滚轮（或滑板）有无缺损与移位？不存在影响救生艇顺利下滑的阻碍。固艇链与释放钩的连接是否正常？不会影响释放钩的顺利脱钩
All parts shall be visually checked, theappliance should always be ensured to be ready for freefall launching lifeboat,as check if guide roller on ramp (or slide plate) is damaged or moved, andwouldn’t affect lifeboat to slide smoothly. Fixing boat chain and release hookare connected normally, and wouldn’t affect release hook to open easily.
1.2 检查压艇装置，压紧板位置是否正确？救生艇是否已被压紧？相关零部件有无缺损？
Check fitted unit, fitted plate should be incorrect place, lifeboat should be held down, and correlative components shouldnot be damaged.
2、月度保养检查 Inspection and maintenancemonthly
2.1 对装置的各部分进行目视检查，保证装置始终处于立即可降放艇的准备状态（包括用吊臂进行降放），如检查滑道情况导向滚轮（或滑板）有无缺损与移位？检查吊臂与绞车的状况，相关零部件是否正常与齐全？各润滑点是否需要补充润滑脂？
All parts shall be visually checked, theappliance should always be ensured to be ready for launching (include using jiblaunching), as check if guide roller on ramp (or slide plate) is damaged or moved,check jib and winch. Correlative components should complete and not be damaged, add lubricating ifnecessary.
2.2 检查压艇装置操作是否灵便？压紧器是否紧压艇舷边？（如为底 部压艇方式则检查压艇装置压艇钩是否紧压小艇固定钩）其相关零部 件是否存在损坏与丢失？

2.5 检查与救生艇相连的释放钩装置，检查其竖钩与装置的焊缝与固艇链有无损伤，链环的任何部位出现裂纹、弯曲或扭曲或其磨损值超 过链径的8%或有明显的永久性伸长时，都应更换。
Check release hook unit connected with lifeboat,check its upright hook、weld andfixing boat chain, chain link should be renewed if there is any crack、bend、distortion、the wear-down more than 8% of Dia. of chain orpermanent elongation.
2.6 检查起升绞车的工作情况，液压绞车部分有无异常的发热、噪声 与漏油？检查箱体内的润滑油的油位与油质，需要时应加以补充。
Check work condition about lifting winch,hydraulic winch shouldn’t have abnormal temperature rise、noiseand leakage, check lubricating oil level and oil quality in box, add if necessary.
2.7 检查液压油缸的动作与渗漏。
Check hydraulic cylinder operation and if any oilleak.
2.8 检查电气部分，它们各自的工作情况，有无元件损坏与失效？
Check electric section and their workingcondition、damage condition and lose efficiency.
2.9 检查液压部分，检查各元件的工作，有无渗漏？
Check hydraulic system working and if any oilleak.
3、年度保养检查 Maintenance and inspectionyearly
3.1 检查滑道、吊臂的腐蚀、移位、变形等等缺陷。
Check corrosion、misalignments、deformationson ramp and jib.
3.2 修补装置的受损油漆，补油漆时注意勿在油嘴及零部件的活动面 上误涂油漆，勿因多次涂漆将相邻零部件间的活动间隙堵塞。
Repair the paint of the appliance, pay attentionthe grease nipple and rotating surface not be covered by paint, active spacebetween border components not be blocked by paint.
3.3 检查吊艇索的损坏与两端连接情况、排绳情况。吊艇索出现扭结、 散股、单股损伤 10%或磨损后直径减少 7%时，不论其是否到达更换期， 都应立即更换
Check damage connect、and rope arrange condition of the boat fall,replace it immediately once find kink, loosed strand, single stranddamaged 10% or worn diameter reduce 7%no matter it is on replace time.
3.4 检查装置上各油嘴与钢绳的润滑，需要时补充润滑脂。
Check and lubricate wire rope and all greasenipple, add if necessary.
3.5 检查滑轮转动的灵活性与是否存在缺损？
Check tackle rotation, possible damages.
3.6 检查吊钩的变形与损伤。
Check lifting hook, if it is damaged ordeformation.
3.7 检查起升绞车的工作，液压绞车部分有无异常的发热、噪声和渗 漏？更换减速箱的润滑油。
Check lifting winch operation. No abnormaltemperature rise、noise and leakage on hydraulic winch, replacelubricating oil in reduction box.
3.8 检查释放钩装置，相关零件有无损坏与变形？见本节2.5 条。
Check release hook unit, include damages and deformations about correlativecomponents, see this section 2.5.
3.9 检查液压油缸的动作与密封，需要时更换密封件。
Check hydraulic cylinder operation and seal,replace seal if necessary.
3.10 检查电气部分，清理与检查电控箱与按钮盒，更换被损元件， 清除电动机内外的灰尘，检查它们的零部件是否有缺损与锈蚀？运转 中不应有异常的声音与振动，有疑问时，检查它们的绝缘与接地。
Check electric section, including clean and checkthe control box and remote control push button box, replace damaged parts,clean the dust inside and outside the electric motor and check its parts, if itis damaged or rusted there is no abnormal noise and vibration when motor is inoperation.
