For heavy-duty rock-breaking tasks that require sustained power, the YZH HA 55 Hydraulic Power Pack stands ready. This unit is specifically engineered to drive large hydraulic hammers and booms with exceptional reliability. Built to withstand the rigors of continuous operation in mines and quarries, the HA 55 delivers the high-flow hydraulic performance essential for maximizing your site's productivity and uptime.

Available Configurations

The HA 55 is available in two distinct configurations, allowing you to select the ideal power solution for your operational strategy and energy efficiency goals.

Standard (HA 55-S)

Perfect for applications requiring consistent, high-output power, the Standard model is a robust and reliable workhorse.

• Vertical Squirrel Cage Motor: A durable and space-efficient motor design.

• Fixed Displacement Gear Pump: Provides a constant, powerful oil flow, ensuring steady and predictable hammer operation.

Heavy-Duty (HA 55-HD)

Designed for superior energy efficiency and performance in variable-demand environments, making it the premier choice for cost-conscious, heavy-duty operations.

• Horizontal Squirrel Cage Motor: A rugged configuration for the most demanding industrial use.

• Variable Displacement Piston Pump: Intelligently adjusts hydraulic flow and pressure to match the system's real-time load. This significantly reduces energy consumption and heat generation, especially during idle periods.

Core Components & Features (All Models)
