GAYA SILINDER STICK DAN SILINDER BUCKET PADA EXCAVATOR 320 CATERPILLAR AKIBAT GAYA POTONG
No full textThe use of heavy equipment to help physical work is very much in use today, One of them is the Excavator. CAT 320 Excavator jeis has many advantages in using, is evident from the construction equipment, design and engineering technology used. In the design of the machine is certainly not independent of the condition of fuel-efficient, compact and easy operation in sistym.Excavato CAT 320 is equipped to do the job of supporting the boom, stick and bucket. Stick used in the job can be changed according to the type of work to be done. Type of stick used is the type R B 1.9, R 2.5 B, R B 2.9, R 3.9 B, M 1, 9 C, M2.4 C, and M 2.9 B and is tailored to the lift cylinder to be used. The length of each stick is 1900 mm, 2400 mm, 250 mm, 2920 mm, 3860 mm. While the bucket capacity (0.7 to 1.2) m3. With the use of the stick and bucket will be analyzed style stick and bucket cylinder and the diameter of the stick and bucket
ANALISA GAYA ANGKAT DENGAN VARIASI SUDUT ELEVASI PADA SILINDER PENGANGKAT EXCAVATOR CAT 320
No full textExcavator usage today is widely used to help the physical work. 320 Excavator machine hasproven its ability to be supported by reliable design, sturdy construction and easy maintenance.320 Excavator with power transfer system of the machine is supported by the cylinder (boom),boom Reach (length 5673 mm), Mass boom (5200 mm), and the VA boom (5460 mm) will beanalyzed starting from the lowest to the highest position elevation angle variations that vary soget the lift cylinder reaction force (Fr) maximum lift on the cylinder
PENGARUH TEMPERATUR DAN BENTUK TAKIKAN TERHADAP KEKUATAN IMPAK LOGAM
No full textThe ability of a material in its use can be influenced by various factors including the temperature. The lower the temperature of the material will be more brittle and conversely the higher the temperature the material will be more resilient, and toughness will also be affected by the presence of defects in material such as cracks, corrosion, holes, etc. and. Impact test is one way to analyze and know the mechanical properties of the material, and the impact test will be the extent to which teperatur and can affect the notch toughness and ductility of the material. It is important to be can know how a material will be feasible or not to be use
PENGARUH SUHU KARBURASI DAN WAKTU TAHAN TERHADAP KEKUATAN TARIK BAJA KARBON DENGAN VARIASI MEDIA PENDINGIN
No full textBaja karbon banyak digunakan sebagai bahan industri karena sifatnya yang bervariasi, dimanabahan ini memiliki sifat lunak dan mudah untuk ditingkatkan kekerasannya, dan sifat baja inidapat diperoleh dengan perlakuan panas. Perlakuan panas dengan variasi pendinginan padawaktu tertentu akan diperoleh sifat mekanik yang diinginkan. Untuk memperoleh kekerasanpermukaan , tahan aus dan mempunyai inti yang ulet serta tangguh maka, Carburizing adalahsalah satu cara perlakuan yang dapat diberikan pada baja karbon untuk meningkatkankekerasan, dengan memberikan variasi pendinginan akan mengakibatkan perubahan dalamkekuatan tarik baja karbon Hal ini dapat dilihat oleh perbedaan kekuatan tarik yang dialami olehbaja karbon dengan pendingin yang berbeda mulai dari air laut, air, minyak, dan udar
