Abstract :
Tower Lamp LS4-6000 adalah alat bantu penerangan portable yang memiliki
sumber listrik sendiri untuk menerangi area pertambangan yang tidak terjangkau oleh
listrik PLN. 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.
