Hydraulic Pusher Ram System

The High-Force Feeding Mechanism for Whole Tire Processing

Hydraulic pusher rams provide the controlled, high-power insertion force required to feed whole tires into primary shredders. These robust systems combine massive pushing power with precision control to ensure consistent material flow while protecting shredder components from impact damage.

Engineered for Extreme Duty Feeding

Constructed with 150mm diameter hardened steel piston rods and heavy-walled cylinder barrels, the ram generates up to 50 tons of pushing force. The system features a reinforced steel push plate with replaceable wear shoes that withstand constant tire abrasion. Dual-acting hydraulic cylinders provide positive control in both extension and retraction strokes.

Precision Control Technology

The ram incorporates proportional hydraulic valves that enable variable speed control throughout the stroke. Programmable logic controls multiple pushing profiles - from gentle starts for light tires to aggressive acceleration for heavy truck tires. Integrated pressure sensors automatically adjust force based on material resistance, preventing equipment overload.

Operational Advantages

The system processes tires from passenger to OTR sizes with cycle times as fast as 6 seconds. Automatic retract sequencing clears jams without operator intervention. The self-cleaning push plate design prevents material buildup. Some models incorporate tire compression plates that flatten tires before feeding for improved shredder efficiency.

Maintenance for Reliable Performance

Daily inspection of hydraulic lines prevents leaks. Weekly cylinder rod cleaning maintains seal integrity. Monthly hydraulic fluid analysis detects contamination early. Annual repacking of all cylinders ensures peak performance. Modern systems feature condition monitoring that tracks hydraulic health and predicts maintenance needs.

Application-Specific Configurations

Specialized versions include: tandem rams for high-volume facilities, heated systems for cold environments, and ultra-high force models for agricultural tires. The latest innovations incorporate smart sensing that automatically adjusts stroke length based on tire size detection.
