2. Core Performance Features
High Torque Output
High reduction ratio design delivers strong traction, suitable for 20-ton excavators traveling in complex working conditions such as mud and steep slopes.
Two-speed Control
Supports high/low speed switching, balancing working efficiency and climbing capacity. High speed for relocation, low speed for heavy-load operation.
High Reliability
Built‑in wet multi-disc brake with sufficient braking torque for safe parking. Wear‑resistant materials and precision machining extend service life.
Wide Compatibility
Can replace models MAG‑170VP-3800, GM38VB, JMV147, etc., compatible with mainstream 19–25 ton excavators.
Easy Maintenance
Modular structure for convenient disassembly, assembly, and overhaul, reducing downtime.
3. Typical Applications
Travel drive for 20-ton excavators
Heavy‑duty conditions in mining, infrastructure and earthwork projects
Compatible models: Doosan DH215/220, Hyundai R200/215, SANY SY195/215, XCMG XE215/235, etc.
