ABSTRAK

Dibidang pembuatan alat-alat berat banyak industri dalam menyelesaikan suatu pekerjaan membutuhkan ketepatan waktu. Maka diperlukan peralatan yang dapat bekerja dengan cepat dan tepat guna. Sebagai contoh pengerjaan benda kerja yang dilakukan pada mesin bubut vertikal dengan diameter meja cekam 2 meter. Dalam prosesnya pembubutan memerlukan bantuan suatu penyangga pada meja cekam justing untuk menjaga posisi benda kerja agar tidak terjadi kemiringan. Berpijak dari hal di atas penulis merencanakan untuk membuat dongkrak hidrolik pararel sebagai alat bantu penyangga benda kerja kapasitas 1ton pada mesin bubut vertikal dengan menggunakan sistem pendorong berupa hidrolisdongkrak hidrolik.Penulis menggunakan dongkrak hidrolis dengan kapasitas 3 Ton 30 kN yang dimodifikasi sehingga daya angkat untuk tiap dongkrak 250 kg. Alat penyangga ini menggunakan 1 terminal berupa hand pump dengan besar tekanan maximal 350 psi.Dengan dibuatnya Dongkrak hidrolik pararel sebagai alat bantu penyangga benda kerja kapasitas 1 ton pada mesin bubut vertical maka dapat ditarik kesimpulan bahwa alat ini mempunyai konstruksi pararel 1terminal 4 cabang yang tiap-tiap cabang mempunyai panjang yang sama sehingga pendistribusian fluida terbagi merata.Berdasarkan hasil perhitungan dapat ditentukan juga dimensi tiap-tiap komponen yang dibutuhkan antara lain piston dengan diameter 26 cm selang hidrolik dengan diameter dalam 2 cm serta bold valvecross dan tee dengan diameter dalam mengikuti diameter selang.


ABSTRACT

In the field of manufacture of heavy equipment in many industries to finish a job requires punctuality. Then the necessary equipment that can work fast and efficient. As an example of progress made on the workpiece vertical lathe work holding table with a diameter of 2 meters. In the process need help turning operation of a buffer on the work holding table justing to maintain the position of workpiece in order to avoid the slope. Based of the above writers are planning to make a parallel hydraulic jack as a tool workpiece support 1 ton capacity on a vertical lathe by using a hydraulic drive system hydraulic jack. The author uses a hydraulic jack to 3 Ton capacity 30 kN which is modified so that the ability to lift for each jack 250 kg. These braces use a terminal in the form of a hand pump with maximum pressure of 350 psi. Hydraulic Jacks made parallel with the workpiece support tool on the 1 ton capacity vertical lathe authors define the construction of this tool is parallel construction 1 terminal four branches each branch having the same length so that the distribution of fluid is divided prevalent. Author also determine the dimensions of each required components include pistons with a diameter of 2.6 cm hydraulic hose with a diameter of 2 cm and bold valve cross and tee with a diameter in the following diameter hose.
