Wheel Loader

Model: CDM843
The rated payload of CDM843 wheel loader is 4 tons, and the rated bucket capacity is 2.3m3. As a medium size wheel loader, this engineering machine (or construction machine) is used widely by our customers worldwide. In order to meet the requirements of overseas market, the new model adopts higher configuration, improved design, and better product performance and cost performance. CDM843 wheel loader is suitable for mine, water conservancy work site, infrastructural construction project, cargo loading/unloading field, road construction work site, etc.
We manufacture 4 ton wheel loader.

Features of CDM843 Wheel Loader:
1. Pilot hydraulic control system is adopted
2. Bucket of CDM843 wheel loader can be automatically leveled and lift kick-out is equipped
3. Air conditioning and heating system provide better operation environment
4. Strong power, front/rear frames are optimized for better accessibility for service
5. Two-pump combined flow hydraulic system ensures energy-saving and easier operation.
6. Hydraulic load-sensing steering system is easier for making turning
7. Anti-abrasion integral cutting edge with teeth and adapters prolong the life of bucket.
