LS4-6000 berarti lighting system yang mempunyai 4 lampu dengan daya 6000 watt. Gerakan tower assy unit Tower Lamp LS4-6000 menggunakan sistem hidrolik. Ada dua masalah pada desain tower assy, yaitu pertama disinyalir silinder 1, 2, 3 over specification karena desain tower assy sama dengan tipe diatasnya yaitu Tower Lamp LS12-24000 dan masalah kedua adanya getaran saat silinder 3 stroke up (mengangkat bracket lamp). Modifikasi desain tower assy unit Tower Lamp LS4-6000 dilakukan dengan metode analisa 5 why, serta perhitungan titik berat, metode syarat momen dan analisa buckling. Tujuannya untuk mendapatkan spesifikasi silinder yang optimal dan menghilangkan getaran pada saat silinder 3 stroke up. Hasil dari penelitian ini adalah didapatkan dimensi silinder hidrolik yang sesuai fungsi, sehingga silinder Tower Lamp LS4-6000 tidak over specification dan kedua hilangnya getaran pada saat silinder 3 stroke up. / Tower Lamp LS4-6000 is a portable lighting tool that has its own power source to illuminate the mining area which is not covered by the electricity grid. LS4-6000 means Lighting System that has 4 lights with a power of 6000 watts. Motion tower assy using hydraulic system. There are two problems in the design of the tower assy, first allegedly cylinders 1, 2, 3 over specification because tower assy design similar to Tower Lamp LS12-24000 and second vibration problems when the cylinder 3 strokes up (lifting bracket lamp). Tower assy design modifications Tower Lamp unit LS4-6000 analysis was conducted using 5 why, as well as the calculation of gravity, moments requirements and analysis methods buckling. The goal is to obtain optimal cylinder specifications and eliminates vibration when the cylinder 3 strokes up. Results of this study was obtained dimension hydraulic cylinders according to the function, so that the cylinder Tower Lamp LS4-6000 not over specification and the loss of vibration when the cylinder 3 strokes up.} }
