DHS Equipment stocks this genuine Multiquip part so you can get your machine back in the trench without delay.
Key Features
- Genuine OEM Spring Tension: — Manufactured to Multiquip's original coil rate and free-length spec, ensuring the correct energy transfer through the ramming stroke.
- Direct Drop-In Replacement: — Engineered to seat in the same position as the factory spring, so installation follows standard MTX service procedures without additional modification.
- Confirmed Fitment: — Verified for MTX70HF, MTX70HDR, MTX80HDR, and MTX70HD rammer models.
- Consistent Stroke Performance: — A correctly tensioned main spring maintains the full impact force and stroke frequency your rammer is rated for, preventing under-compaction on cohesive soils.
- Durability Under Repetitive Impact: — Built to withstand the high-cycle fatigue demands of rammer operation, where the spring compresses and rebounds thousands of times per hour.
The main spring in an MTX rammer is the central mechanical component responsible for storing and releasing energy during each compaction stroke. As the engine drives the exciter mechanism, the spring compresses and rebounds to propel the foot downward with controlled force, delivering the impact energy that densifies the soil. When the main spring weakens, cracks, or breaks, the rammer loses stroke height and impact force, resulting in poor compaction depth and uneven soil density — making prompt replacement critical for consistent results.
