Strong Impact Absorbing Excavator Auxiliary Hydraulic Cylinder Complete Ram Assembly Matched With Hydraulic Rock Breaker For Quarry Mining Crushing Works

Parameter:

Product Descripition:

1. Our factory supplies complete replacement hydraulic cylinder assemblies including boom, arm and bucket cylinders for various construction excavators.

2. Equipped with chrome-plated piston rod and high-strength seamless cylinder tube plus premium sealing kits, the cylinder effectively avoids oil leakage under heavy-load construction and mining work.

3. We support OEM customization per drawings or samples, compatible with Cat, Komatsu, Hitachi, Doosan and Hyundai excavators.

4. All products pass pressure test before delivery, standard export packing for sea shipment to Africa, Middle East and Southeast Asia.

Working principle of hydraulic cylinder:

This auxiliary hydraulic ram assembly is specially matched with hydraulic rock breakers for quarry crushing operation, adopting built-in shock absorption buffer structure to realize strong impact absorption function.

High-pressure hydraulic oil from the excavator main pump flows into two independent oil chambers of the auxiliary cylinder, pushing the piston to perform reciprocating telescopic movement. When the rock breaker strikes hard rock and generates instantaneous reverse impact force, the cylinder’s built-in buffer cavity forms an oil damping layer instantly, offsetting violent shock wave and avoiding rigid impact damage to the excavator arm and main hydraulic system.

During continuous crushing cycles, the cylinder balances the pressure fluctuation of the breaker’s nitrogen energy storage system, stabilizes the feeding and pressing force of the hammer drill rod, and ensures consistent impact frequency. The integrated full ram assembly transmits steady auxiliary thrust, effectively reducing vibration transmission to the whole machine, lowering component wear, and extending the service life of both excavator and rock breaker under long quarry heavy-load crushing conditions.

Application: 

This complete auxiliary hydraulic ram assembly with strong impact absorption is perfectly matched with hydraulic rock breakers, designed to cope with high-frequency impact working conditions in heavy crushing industries.

1. Open-pit quarry & stone aggregate plant Secondary crushing of oversized granite, limestone and basalt blocks after blasting, feeding qualified small stones into crushers, reducing blockage failures of crushing equipment. The built-in shock absorption structure offsets violent impact rebound during long continuous stone breaking.

2. Open-pit mining & ore exploitation Crushing hard ore rock, clearing large boulders on mine stope and grizzly screen to ensure smooth ore conveying, suitable for gold mine, iron mine and non-ferrous metal mine operations.

3. Tunnel & underground engineering Scaling loose rock on tunnel walls, breaking hard rock layers in narrow underground roadways, mitigating vibration damage to excavator main arm and hydraulic system under confined space frequent impact work.

4. Infrastructure road construction Hard rock foundation excavation, mountain road widening, rocky trench digging, replacing blasting in environmentally sensitive construction zones to control vibration range.

5. Concrete demolition & waste recycling Breaking reinforced concrete blocks at construction waste recycling yards, buffering impact force generated by long-time crushing of rigid building materials.

Its excellent impact absorption performance effectively isolates instantaneous shock wave from rock breaker striking, stabilizes auxiliary pushing force, protects excavator hydraulic system and prolongs the service life of the whole machine under long-term heavy-load crushing work.
