Features
1. The backhoe loader 620CH is installed with Cummins engine from Dongfeng.
2. It has four 4 forward and 4 reverse synchromesh mechanical shift transmissions.
3. For high safety, the ROPS/FOPS cab is designed with wide space to create comfortable driving environment and good visibility.
4. This product can be manufactured with 4 wheel drive for option. The construction machinery uses CARRARO front axle and CARRARO wet-type rear axle with multi-disc brake.
5. The pilot valve controlled loader, as well as the backhoe valve, makes for easy and flexible operation of the backhoe loader.
6. Smartly designed, the extendible dipper for the excavator greatly reduces the travelling distance and improves the working efficiency.
7. The arm of the wheel loader can be extended to increase the working range.
