Understanding NPK Hydraulic Hammers: A Comprehensive Guide
NPK hydraulic hammers, commonly referred to as breakers, are essential tools in the construction and demolition industries. Known for their durability and efficiency, these hammers have gained popularity due to their robust design and effective performance in breaking through tough materials. This article explores the features, specifications, and operational guidelines of NPK hydraulic hammers, particularly the GH series.
What is an NPK Hydraulic Hammer?
NPK hydraulic hammers are powerful devices that use hydraulic pressure to break concrete, rock, and other hard surfaces. Unlike many nitrogen-fired hydraulic hammers, NPK models do not have onboard accumulators. Instead, they utilize two hydraulic hoses to deliver oil into the cylinder, ensuring a consistent and reliable operation.
Key Features of NPK Hydraulic Hammers
-
Side Plated Design: Most NPK hydraulic breakers feature a side plated cradle design. This structure sandwiches the power cell between two large plates, secured by double-ended cross bolts, which enhances stability and durability.
-
Vibration Absorption: NPK models are equipped with large square side buffers that absorb vibrations, reducing wear and tear on the hammer and improving user comfort during operation.
-
Auto Lube Connection: The GH series comes with an auto-lube connection port, allowing for an automatic greasing system. For those not utilizing this system, manual greasing is also possible, ensuring the hammer remains well-maintained.
-
Underwater Capability: NPK hydraulic hammers are designed with specific ports that allow for underwater operation, making them versatile tools for various construction scenarios.
NPK GH Series Specifications
The NPK GH series includes various models, each tailored for specific applications and carrier weights. Here is a quick overview of some models:
| Model | Working Weight | Recommended Carrier Weight |
