1. Power system

Everun 1T excavator is equipped with single-cylinder air-cooling diesel engine.

2. Drive system

Everun 1T excavator's drive system could transfer the output power from diesel  engine  through  the hy-  draulic system to work equipment, swing mechanism and traveling mechanism.

3. Swing mechanism

Swing mechanism could turn the work equipment and upper rotary leftwards and rightwards, so as to do the excavating and the unloading. Everun 1T excavator’s swing mechanism  has  to  fix  the  rotary  table  onto frame and has it swing flexibly, without any inclining risk. Therefore, Everun 1T excavator is equipped with a slewing support (supports) and a slewing drive (power of turntable slewing), which are called by a joint name as swing mechanism.

3.1 Slewing support

Everun 1T excavator has its rotary table supported with a rolling bearing, realizing the swinging of upper rotary.

3.2 Rotary drive

Everun 1T excavator adopts the direct drive type. Namely, the output shaft of low-speed high-torque hy draulic motor is mounted with a driving pinion which meshes with the slewing gear ring.
