CAT CAT®303.5E CR Cab Mini excavator
Product Feature
Stability
303.5E CR Excellent stability，While maintaining a compact radius design。
Higher stability enables the use of heavier tools，Thereby improving productivity，Enhance versatility。
Faster with Load Sensing Hydraulic System、More powerful digging.
High breakout forces and short cycle times provide the productivity you need。
Load-sensing hydraulics optimize flow，Get smooth, powerful performance and better fuel efficiency。
200 degree bucket rotation
Industry-leading bucket rotation of more than 200 degrees provides enhanced material retention during truck loading。
It allows for easier vertical wall excavation，No need to reposition the machine。
