Page 7: Chapter Ii Basic Structures And Work Principle Of Carter 0.6T Excavators
1-1. Mounted on the rotary table are the regular full-swing type hydraulic excavators, main components of drive system, swing mechanism and auxiliary devices, which are referred to as upper rotary. Therefore, a Carter 0.6T excavator is divided into work equipment, upper rotary and traveling mechanism. - Page 8 Section II Work principle of excavators Diesel engine changes the chemical energy of diesel into mechanical energy that is then altered with hydraulic gear pump to hydraulic energy that is distributed to each actuating element (such as hydraulic cylinder, swing motor and traveling motor).
- Page 9 The hydraulic excavator could have multiple work equipment, up to dozens of varieties, with backhoe and ripper most popular. Carter 0.6T excavator has the boom, arm and bucket articulated with each other, as shown in figure and swing around their articulated points respectively with aid of the hydraulic cylinder, finishing the excavating, lifting and unloading.
- Page 10 5.2 Bucket 5.2.1 Basic requirements The longitudinal profile of bucket meets the law of motion of various materials inside of bucket, facilitating the material flow and minimizing the loading resistance and thus fulfilling the bucket. Bucket teeth are mounted to increase the linear specific pressure of bucket onto material, with unit cutting resistance relatively low and easing to cut in and break soil.

Page 16: Chapter Iii Service Technologies Of Carter 0.6T Excavators
Chapter III Service Technologies of Carter 0.6T Excavators Being of high temperature and pressure, the Carter 0.6T excavator could have the hydraulic oil temperature as high as 85℃, the engine silencer temperature as high as 700℃ and pressure as high as 16-18MPa. Therefore, the operators should be specially trained to obtain the proper certificates and to be familiar with the contents in this manual before the operations. - Page 17 When hydraulic oil is less than 25℃, it is needed to preheat the machine before any work; otherwise machine may not respond or react very quickly, leading to severe accident. Therefore it is needed to preheat machine if it is cold: ①.
- Page 18 2.2 Basic excavation 2.2.1 Before excavation, the arm cylinder should have angle with the arm as 90° , bucket with ground to be excavated as 30° . Only in such case, can each cylinder have the max. excavating force. It is suitable for relatively hard soil, so as to decrease the excavating resistance.
