Configuration
1. Diesel engine:2pcs of Cummins 265Kw/2200 rpm
2. Hydraulic pump:4pcs of variable plunger pump with each output 190ml, from German Rexroth A11V series;
3. One gear pump of each 32ml/r and 25ml/r from Jinan.
4. Main motor: 14pcs of SH7V variable plunger motor with capacity 108ml from Italian Sam, used for rotation and push&pull in driving head.
5. 14pcs of reducers from Italian Dynamics or German KPM for rotation and push&pull in driving head.
6. 2sets of coupling originally imported from Germany.
7. Alloyed steel rack and pinion with abrasion-resistant and impact-resistant .
8. PLC-control circuit is simplified, more steady and more intelligent.
9. 3T crane.
