STM ST121 Hydraulic Hammer

Sintash presents a new generation of ultra-heavy-duty hydraulic hammers to industry specialists with the introduction of the STM ST121 model. This hammer, the result of combining years of STM engineering experience with the latest technological innovations, has been developed to meet the most complex and demanding needs of civil, mining, and strategic demolition projects. The ST121 model not only showcases extraordinary raw power but also defines new standards in this class of equipment with its intelligence and optimal efficiency.

Prominent Features and Strengths of the STM ST121 Hydraulic Hammer:

• Devastating Impact Energy with Optimized Transfer Rate: Utilizing an innovative design in the hydraulic system and impact mechanism, the ST121 generates exceptionally high impact energy and transfers it to the chisel with minimal loss. This feature significantly increases the speed of breaking operations in the toughest materials.
• Monoblock Body Structure with Advanced Alloys: The use of steel alloys with very high tensile strength and hardness, combined with an integrated and reinforced design at key points, brings unparalleled durability and lifespan to the ST121 even in the harshest and most abrasive working conditions.
• Intelligent Performance Management System: Equipped with advanced sensors and an electronic control unit that continuously monitors the hammer’s performance and automatically adjusts parameters such as frequency and impact power to achieve maximum efficiency and minimum wear.
• Multi-Layer Vibration & Noise Dampening Technology: By using a combination of advanced polymer buffers, an internal suspension system, and an acoustically optimized body design, the level of generated vibrations and noise has been significantly reduced. This leads to increased operator safety and comfort and protection of the excavator.
• Easier Maintenance and Serviceability for its Working Class: Despite its large dimensions and high power, special attention has been paid in the design of the ST121 to ease of access to main service points and reduced maintenance intervals to minimize equipment downtime.

The STM ST121 Hydraulic Hammer is designed for very heavy-duty and specific applications, including: massive demolition projects of heavily reinforced and voluminous concrete structures, primary extraction in hard rock quarries with resistant veins, excavation and site preparation operations in large infrastructure projects such as bridge building, dam construction, and power plant erection.
