Page 7 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 CAEL-1T excavator is divided into work equipment, upper rotary and traveling mechanism.
Page 8 Capital Automotive Equipment Limited. 245 lottridge st hamilton ontario ，L8L 6W1 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: Section Iii Basic Structure Of Cael-1T Excavators Mechanical System
3.1 Slewing support CAEL-1T excavator has its rotary table supported with a rolling bearing, realizing the swinging of upper rotary. 3.2 Rotary drive CAEL-1T excavator adopts the direct drive type. Namely, the output shaft of low-speed high-torque hydraulic motor is mounted with a driving pinion which meshes with the slewing gear ring.

Page 16: Section Ii Preparation For Work
Capital Automotive Equipment Limited. 245 lottridge st hamilton ontario ，L8L 6W1 Chapter III Service Technologies of CAEL-1T Excavators the hydraulic oil temperature of excavator can high to 85℃, Being of high temperature and pressure, CAEL-1T the engine silencer temperature can high to 700℃ and pressure can high to 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 Capital Automotive Equipment Limited. 245 lottridge st hamilton ontario ，L8L 6W1 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.
Page 18 Capital Automotive Equipment Limited. 245 lottridge st hamilton ontario ，L8L 6W1 2.2 Basic excavation 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.
