STM ST70 Hydraulic Hammer

By offering the STM ST70 Hydraulic Hammer, Sintash provides a new standard of power and performance for massive projects and extremely heavy-duty operations. This model, ranking among the largest and most powerful STM hydraulic hammers, is engineered to confront the toughest geological conditions and most resistant structures. The ST70 is an unparalleled choice for contractors seeking maximum productivity, operational speed, and reliability in large-scale projects, who settle only for the best.

Defining Features and Strengths of the STM ST70 Hydraulic Hammer:

• Devastating and Unrivaled Impact Energy: Utilizing an ultra-advanced hydraulic system and a piston with a very large diameter and stroke, it generates immense impact energy capable of crushing the hardest types of rock (such as granite and basalt) and very high-density reinforced concrete in the shortest possible time.
• Extreme Duty Alloy Steel Structure: All main components, including the body, cylinder, and piston, are made from special steel alloys with exceptionally high tensile strength and hardness, and have undergone complex heat treatment processes to ensure flawless performance against severe shocks, abrasion, and fatigue from continuous work.
• Advanced Vibration Dampening System: Equipped with multiple internal and external mechanisms to absorb and reduce vibrations transmitted to the excavator and operator, which significantly contributes not only to comfort and safety but also to the lifespan of the excavator components and the hammer itself.
• Intelligent Energy Management & Lubrication Technology: Some versions may feature automatic frequency and impact power adjustment systems based on material hardness, as well as an integrated automatic lubrication system, which helps optimize performance and reduce maintenance needs.
• Designed for the Largest Excavators: Precise engineering of connections and weight balance allows for safe and efficient installation and operation on very high tonnage excavators (please consult Sintash experts for exact compatibility).

The STM ST70 Hydraulic Hammer is ideal for very specific and large-scale applications, including: massive open-pit mining projects for primary breaking of very hard rocks, demolition of giant concrete structures and deep foundations, large-diameter drilling in rocky areas, and large infrastructure projects such as dam and tunnel construction that require continuous and maximum demolition power.
