Project Location: Asunción, Paraguay
Equipment: HWX1400 Top Type Hydraulic Breaker (20 Ton Class)
Carrier Machine: SANY SY215 Excavator
Application: Primary Rock Breaking & Quarrying
Project Overview
In a large-scale infrastructure project in Paraguay, the client required a high-efficiency solution for breaking hard volcanic rock and granite. The project demanded continuous operation under high-temperature conditions. After comparing several brands, the client chose the JINAN CHANGHAO (HWX) 20-ton top-type hammer for its reputation for hitting power and durability.
Why Choose the HWX1400 Top Type?
Superior Impact Power: The HWX1400 (SB81 compatible) features a 140mm chisel diameter, providing the high kinetic energy needed to penetrate hard rock layers.
Top Type Advantage: The vertical (top) design provides a longer reach and higher striking force, making it ideal for deep trenching and vertical quarrying tasks.
Perfect Match for SANY: Designed to be 100% compatible with the SANY SY215 hydraulic system, ensuring smooth oil flow and preventing overheating.
Premium Material: Manufactured using 20CrMo alloy steel with advanced vacuum heat treatment technology, significantly extending the service life of the cylinder and piston.
Performance on Site
Since its deployment, the HWX1400 has shown exceptional stability. The client reported that the “Ready-to-Work” configuration allowed for immediate installation. Even when working on the toughest rock sections, the hammer maintained a consistent strike frequency without power loss.
The Jinan Changhao team provided full technical support, ensuring the “Three Golden Parameters” (pin diameter, center distance, and ear width) were perfectly matched for a seamless “plug-and-play” experience.
Client Feedback
“The HWX1400 hammer has transformed our 20-ton SANY excavator into a rock-breaking beast. The maintenance is simple because it is fully compatible with Soosan SB series parts, which are easy to find here in South America. It is the most cost-effective investment we’ve made this year.” — Project Manager, Paraguay Construction Group.
