Section III Basic structure of HYTEC F1000 Excavator mechanical system 

 

1

 

Power system 

HYTEC F1000 Excavator is equipped with single-cylinder air-cooling diesel engine. 

2

 

Drive system 

HYTEC F1000 Excavator's drive system could transfer the output power from diesel engine through the  hydraulic 
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. HYTEC F1000 Excavator’s swing mechanism has to fix the rotary table onto  frame 
and  has  it  swing  flexibly,  without  any  inclining  risk.  Therefore,  HYTEC  F1000  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 

HYTEC F1000 Excavator has its rotary table supported with a rolling bearing, realizing the swinging of 
upper rotary. 

3.2

 

Rotary drive 

HYTEC F1000 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. . 

4

 

Traveling mechanism 

Traveling mechanism supports the complete weight of excavator and drives it to run. 

HYTEC F1000 Excavator has the crawler traveling mechanism similar to other crawlers, with one hydraulic motor 
driving  one  track.  This  excavator  adopts  low-speed  high-torque  motor.  When  two  hydraulic  motors  run  in  the 
same direction, this machine goes straightly forward; when one motor is supplied with oil and the other is braked, 
excavator steers around the braked track; when two motors runs reversely, excavator rotates in situ. 

Each  part  of traveling  mechanism  is  mounted  on integral  traveling frame.  The pressure oil from  hydraulic pump 
goes  through  the  multi-way  directional  valve  and  the  central  swing  joint  into  the  hydraulic  traveling  motor  that 
changes the pressure energy into output torque that then goes to sprocket, driving excavator to run. 

HYTEC  F1000  Excavator’s  sprockets  are  of  integral  castings  and  able  to  correctly  engage  with  track,  featuring 
balance  drive.  Sprockets  located  at  rear  part  of  excavator,  shortening  the  tensioner  part  and  relieving  the  track 
abrasion,  wear  and  power consumption.  Each  track  is equipped  with a tensioner,  adjusting the  track  tension and 
reducing the track vibration noise, abrasion, wear and power loss. 

5

 

Work equipment 

The hydraulic excavator could have multiple work equipment,  up to dozens of varieties, with backhoe and ripper 
most popular. 

HYTEC F1000 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. 

5.1

 

Boom 

As the  main component  of backhoe  work equipment,  the integrated skewed boom is adopted  on  HYTEC F1000 
Excavator. 

Being  of  the  most  popular  type  at  present,  skewed  boom  could  allow  excavator  to  dip  deeper  and  to  lower  the 
unloading depth, satisfying the backhoe requirements.
