![]() “The model year does a pretty good job of telling you what’s in there,” says Meeker. There will still be annual product updates and new feature sets for dozers and other machines, but contractors will need to know the year-model or the serial number to know which machines have which updates. In the past, the suffixes on Cat dozer names typically designated different feature sets. Meeker says you might/could see this on dozers a year or two down the road. The GC moniker was used to denote a basic, no-frills machine with a lower cost and less technology than the more fully featured machines. Kabin telah dipersiapkan dengan kabel untuk radio 12-volt atau 24-volt, dilengkapi dengan dua buah speaker, sebuah antena dan tempat pemasangan radio di langit-langit kabin.The other suffix you might eventually see on the dozers is the GC designation, which is already used on some excavators (320 GC, 330 GC, 336 GC ) and one wheel loader (the 950 GC). Ventilasi heater dan AC mendistribusikan aliran udara dalam kabin secara merata. Sistem memberikan tiga tingkat peringatan dan monitoring sistem sehingga operator selalu mendapatkan informasi sekaligus tetap berkonsentrasi pada pekerjaan. Sistem Monitoring Elektronik (EMS, Electronic Monitoring System) menampilkan indikator peringatan yang memonitor komponen utama alat berat. Pengukur dan lampu peringatan pada panel instrumen dashboard mudah dibaca, bahkan di bawah sinar matahari langsung. Kursi ini dilengkapi dengan penyetel posisi dan sandaran tangan yang dapat diatur untuk mendapatkan platform yang nyaman saat bekerja pada permukaan miring atau curam. Kursi Seri Comfort dengan kemiringan 15 derajat untuk kemampuan pandang yang lebih baik. Jendela kaca besar berpanel tunggal memberikan pandangan yang baik ke sekitar alat berat untuk produktivitas maksimum dan meningkatkan keselamatan di lokasi kerja. This reduces owning and operating costs, and saves raw materials and natural resources.ĭ8R dilengkapi kabin bertekanan dengan isolasi yang mengurangi kebisingan dan getaran. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components. Modular undercarriage components simplify service. Modular power train components make it quick to remove and repair the transmission, final drives, steering differential or brakes. Higher traction means less slippage, better balance, and a smoother ride. The bogie suspension conforms closely to the ground providing up to 15 percent more ground contact, especially in hard, uneven terrain. The suspended undercarriage design absorbs impact loads to reduce the shock loads transferred to the undercarriage by up to 50 percent in uneven terrain. However, machine center of gravity remains low, offering excellent stability, balance and traction. The elevated sprocket design gives the operator excellent sight lines to the blade, sides and back of the machine. Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer component life. This is a field-proven design that offers outstanding machine performance and longer component life. Since its ground-breaking introduction in 1978, the Cat elevated sprocket undercarriage arrangements allow optimized balance for best possible performance in each application. The tag-link provides solid lateral stability and eliminates the need for diagonal bracing since it transfers side loads to the mainframe instead of dozer push-arms. ![]() The D8R also features the tag-link design to mount the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. A low friction, no maintenance bushing is used in the saddle connection and resilient pads restrain equalizer bar oscillation. Equalizer bar end pins are oil filled with limited slip seals for longer life and reduced repair costs. The pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort. This design eliminates alignment problems and the need for diagonal braces on the roller frames. The full-length pivot shaft distributes impact loads throughout the case, reducing bending stresses on the case. The pivot shaft runs through the mainframe and connects the roller frame for independent oscillation. Castings provide added strength to the main case and equalizer bar saddle. The foundation of every Cat dozer is a rugged frame built to absorb high impact shock loads and twisting forces.
