Accumulator Cover (Part No. 86374055) – Suitable for Montabert HC109 Rock Drill

The Accumulator Cover, part number 86374055, is a durable and precision-engineered component designed for the Montabert HC109 rock drill. It forms the protective enclosure for the hydraulic accumulator assembly, helping to maintain system pressure, protect internal elements, and ensure consistent impact performance.

Description

The accumulator cover is manufactured from high-strength alloy steel to withstand the high pressures, vibration, and impact forces typical in heavy-duty rock drilling operations. It seals the accumulator chamber — where nitrogen gas and hydraulic fluid interact — ensuring pressure is maintained and leakage is prevented.

Proper function of the accumulator cover is essential for stable energy storage and release, which directly influences the efficiency and reliability of the impact mechanism. Its robust design also protects the internal accumulator components from contamination, damage, and wear.
