Abstract

In a repair shipyard company there is a constraint, which in the field conditions require adevice that can be used to lift objects or goods that have a small capacity and can reach the height ofthe deck from the ship. But in the lifting products that already exist, when it has a small capacity thenhas a small lift height. And when it wants to take a lift height as its lift capacity also rises based onthe above problems it is necessary to design a new lift tool that can meet those needs.In this research,the lifting equipment is a mobile crane. So that it can be moved as well as the effectiveness of theplace of the shipyard. To meet the lift strength and lift level needed, it is necessary to analyze thestrength of the structure using the finite element method or FEM.In the design is expected to help forthe improvement and addition of existing facilities in the shipyard in Indonesia. In the results of theresearch, there are still some disadvantages, namely that in some calculations below the deck areignored, so that in the future there needs to be a calculation under the deck from the mobile crane.

Abstract

PT. Adiluhung Saranasegara Indonesia (PT. ASSI) is one of the companies engaged in the shipping industry. In terms of cost efficiency and field area conditions, the company established 3 types of docking facilities, including Slipway, Launching way, and Floating dock. Every company should have specification data from each facility. But in one of the facilities that are often used in PT. ASSI, launching way, there is a problem with the winch used. The winch doesn't have a complete specification book, so the company doesn't know the power used on the winch. Therefore, in this study presented the calculation of power used in launching way by using ship data that is doing the docking at PT. ASSI. In this calculation, there are several steps, namely the calculation of sling tensile, attractiveness speed, winch pull force, drum, and finally the calculation of torque and power of the electric motor. The result of this study is using 8/1 system pulley, the tensile winch's force is 162,374 k. With the time of docking around 4 hour, the ship's tensile speed is 0,0514 m/s. The result of the power used is 75 kW with a torque of 82810,519 Nm.

Abstract

The increasing demand for railway transportation requires locomotive components to meet high safety and performance standards. One critical component is the shaft, which transmits power from the engine to the wheels and supports the locomotive's total load. This study analyzes the stress and deflection of the CC 203 locomotive shaft using empirical calculations. The shaft, made of ST 52 steel with a ready load of 84 tons and dimensions of 2000 mm in length and 150 mm in diameter, was evaluated based on allowable limits. The results show a maximum stress of 112.27 MPa and a maximum deflection of 4.3 mm, both within the allowable limits of 260 MPa and 5 mm, respectively. These findings indicate that the shaft design meets structural safety and operational reliability requirements. Regular inspections are recommended to maintain optimal performance and prevent material degradation over time.
