Main Features
1. ZG3335LC-9C hydraulic crawler excavator manufactured by Changlin carries the original Cummins C series engine which provides outstanding durability and suitability for high strength and heavy load works in harsh conditions, combined with strong power, low oil consumption and compliance with Euro II emission qualification.
2. Due to a negative flow and total power control system with action coordination, it ensures large digging force, high efficiency and perfect flexibility.
3. High strength large structural components, heavy moving arm, bucket rod and reinforced bucket enable this construction equipment to bear severe working conditions such as mine.
4. Lengthened and widened chassis boasts high intensity, making working more stable and safer.
5. The crawler  excavator is designed with an intelligent electronic monitoring system which provides real time monitoring, automatic fault diagnosis and warning, maintenance reminding functions.
6. New type driver cab is provided with a fully automatic air conditioning. It is spacious and comfortable, and comes with an eye-catching appearance. The cab is available in various protections for different working conditions.
