One of recent concerns for super-tall buildings is how to manage hoisting plans and equipment efficiently. Disasters are frequently occurred in relation to electromotive hoists and cranes which are commonly used in construction sites. For construction lifts, particularly, it is highly important to conduct regular inspections or prepare against breakdown in terms of safety. However, unfortunately the reality is that regular inspections are only flatly conducted according to operating hours only. A lift, whose life span is subject to the complicated considerations such as operating hours, loading condition, and the like of each component, is far too invalid as a means of maintenance. As a way to resolve this problem and improve its convenience and safety for users, this study intends to calculate individual inspection interval for the main components of lifts by measuring their actual operating hours with sensing technology and analyzing their historical data. The findings of study include calculation of inspection intervals for the main components of lifts and classification of components to check by the actual operating hours of lift (40, 90, 130, 400 hours), which are drawn up into tables. This will make an opportunity to suggest efficient maintenance measures by enabling prevention of safety accidents and enhancement of safety for workers. Also, it will lead to increasing productivity of works by eliminating sources of delaying the term due to the breakdown of lifts.

This paper analyzes the type of facilities and equipment of the marina port and analyzes its lift facilities (lift pier) and equipment (marine mobile lift). It set up the lift facilities and equipment standards. Depending on the gross tonnage of vessels in operation in Korea, the required inner width of lift piers is 5.50 m for 35-ton vessels, and 6.20 m for 50-ton vessels. The inside width of the marine mobile lift is 6.10 m for 35-ton vessels, and 6.80 m for 50-ton vessels. There are two places where the target ship can be lifted from the lift pier installed on the domestic marina, and other marinas' lift piers inner widths are insufficient by about 0.35 ~ 0.50 m. Among the marine mobile lifts in operation, there were two apparatuses that secured the inside width necessary to lift the target vessel. Other marine mobile lifts' inner widths are insufficient by about 0.3 ~ 0.6 m.
