Premium Features & Core Strengths
Low-Emission CAT Original Power Assembly
- This CAT 320GX excavator equips genuine CAT C4.4 Stage V diesel engine, passing global multi-climate endurance verification. It outputs stable low-speed torque to support all digging, lifting and loading tasks of the 20 ton crawler excavator. Built-in multi-stage fuel filtration removes diesel impurities to lower engine wear, extending the service life of this CAT hydraulic digger by over 20% compared with refitted generic engines.
Intelligent Energy-Saving Hydraulic Circulation System
- This construction crawler excavator is fitted with independent hydraulic cooling loop. Even after 8+ hours nonstop operation, hydraulic oil stays within safe temperature range to avoid power attenuation caused by overheating. Load-sensing flow matching technology auto-adjusts hydraulic output based on working load, slashing daily fuel consumption of this CAT medium excavator by 15%.
Thickened Reinforced Working Arm & Wear-Resistant Bucket
- The boom and stick of this industrial digging machine adopt high-tensile thick steel plates with full penetration welding to resist impact from rock excavation and heavy material handling. Standard digging bucket comes with replaceable wear teeth; users only swap worn teeth instead of the whole bucket, effectively cutting later maintenance costs of CAT 320GX excavator.
Humanized Noise Reduction Operator Cabin
- This 20 ton crawler excavator has fully sealed cabin equipped with shock-absorbing suspension seat and thick sound insulation cotton, limiting operating noise below 77 decibels. Panoramic front and side windows provide full 360° vision, matched with anti-slip pedals and integrated control joysticks, enabling new operators to master this CAT hydraulic digger quickly with short training.
Convenient One-Side Maintenance Design
All daily service components of the construction crawler excavator are arranged on side panels with wide opening maintenance hatches. Operators can finish engine oil replacement, filter inspection and hydraulic oil filling without climbing the machine. Standardized component interfaces of this CAT medium excavator match global official CAT spare parts, eliminating the trouble of hard-to-source accessories for industrial digging machine owners.
