The Engine of Your Productivity: The HA 37 Hydraulic Power Pack

Introduction

A rockbreaker boom system is only as reliable as its power source. The YZH HA 37 Hydraulic Power Pack is the proven workhorse for mid-sized hydraulic hammers and booms, delivering consistent and efficient power. Designed to operate flawlessly in demanding industrial environments, the HA 37 provides the optimal flow and pressure needed to keep your operations running smoothly and productively.

Available Configurations

We offer two distinct configurations of the HA 37, allowing you to select the perfect balance of performance and efficiency for your specific application.

Standard (HA 37-S)

The ideal choice for steady, predictable workloads, our Standard model offers robust and straightforward performance.

• Vertical Squirrel Cage Motor: A reliable, space-saving motor design.

• Fixed Displacement Gear Pump: Delivers a constant and stable oil flow, ensuring consistent and predictable hammer performance.

Heavy-Duty (HA 37-HD)

Engineered for maximum efficiency in operations with variable workloads, reducing energy consumption and operational costs.

• Horizontal Squirrel Cage Motor: A rugged configuration built for sustained, heavy-duty use.

• Variable Displacement Piston Pump: Intelligently adjusts oil flow to match the system's real-time demand. This provides superior energy efficiency by minimizing wasted power and heat generation during idle or low-load periods.

Core Components & Features (All Models)

Every YZH HA 37 power pack is delivered as a fully integrated, turnkey solution built for longevity and ease of maintenance.

• Advanced System Filtration: High-quality pressure and return filters protect sensitive hydraulic components from contamination, maximizing the service life of your hammer and boom.

• High-Efficiency Oil Cooler: Maintains optimal hydraulic fluid temperature during continuous operation, preventing overheating and ensuring stable, reliable performance.

• Complete Electrification: Arrives ready for immediate integration with standard voltages (400V/50Hz or 480V/60Hz, with other options available) and features an IP55-rated enclosure for protection against dust and water.

• Optional Oil Heater: Guarantees reliable start-ups and peak performance in cold-weather environments.
