In order to keep and to protect the goods that are being transported through long distance, <br />
<br />
<br />
containers are used as storage media. Therefore, number of containers are increasing every year. <br />
<br />
<br />
Container cranes are used to move container from ship to dockside or vice versa. Container cranes <br />
<br />
<br />
use electric motors as prime mover and holding brake to hold the moving parts of container crane. <br />
<br />
<br />
In the design stage, calculation of motor power and braking torque should be done accurately in <br />
<br />
<br />
order to find out whether crane is functioning properly or not. <br />
<br />
<br />
In this final project, calculation of motor power and braking torque is done by using the <br />
<br />
<br />
equation from Doosan[1], Verschoof[2], and MAN[3]. There are 4 driving systems on container <br />
<br />
<br />
crane namely main hoist, trolley travel, gantry travel, and boom hoist. Calculation of motor power <br />
<br />
<br />
and braking torque is done for each driving system. In order to facilitate the analysis, a program <br />
<br />
<br />
has been developed for each driving system. The calculation result for each driving system is then <br />
<br />
<br />
compared with information from Doosan and MAN as crane makers. <br />
<br />
<br />
It was found from the comparison of the results that the computer program works properly. <br />
<br />
<br />
Calculation of motor power using three references showed acceptable results. Brake torque <br />
<br />
<br />
calculations carried out using the developed computer program showed reasonable results. <br />
<br />
<br />
Differences in calculation result are caused by different assumption used by the three references <br />
<br />
<br />
due to lack of system and operating information. Should there be a complete system and operating <br />
<br />
<br />
information, calculation using developed computer program would give more accurate result. |
