Product Description

SK81S Silent Hydraulic Breaker | 18-25 Ton Excavator Mounted Hammer

Tailored for modern environmentally friendly construction needs, the SK81S low-noise hydraulic hammer is a mid-sized demolition tool that balances powerful crushing performance with ultra-quiet operation. Compatible with 18 to 25-ton excavators, this upgraded hydraulic silence breaker features a simplified assembly and disassembly structure, delivering great flexibility for diverse construction tasks. Different from traditional noisy breaking equipment, this model effectively cuts down working noise while guaranteeing stable output power, making it a perfect fit for urban renewal, interior remodeling, residential zone construction and projects adjacent to public and noise-sensitive venues.

Core Product Features & Competitive Strengths

1. Ultra-Quiet Running, Eco-Friendly Construction

To solve the noise pollution problem of conventional hydraulic breakers, the SK81S adopts a dual-layer sound insulation shell and built-in vibration damping buffer system. The innovative structural design effectively isolates vibration and hydraulic impact noise generated during operation, keeping the on-site noise range steadily at 78dB to 85dB. Far superior to standard industrial products in noise control, it fully complies with urban environmental protection construction standards, avoiding noise complaints and meeting the strict construction requirements of densely populated urban areas.

2. Robust Impact Power for Efficient Demolition

Fitted with a high-performance high-pressure hydraulic system, this silent hydraulic breaker supports a maximum working pressure of 160 bar and a variable striking frequency of 1800–2200 beats per minute. The steady and strong impact force enables one-time efficient breaking of concrete, natural rock, asphalt pavement and other rigid construction materials. It effectively optimizes the construction process, reduces redundant operation cycles, and significantly improves the overall progress and working efficiency of demolition projects.

3. Premium Material Craftsmanship for Extended Service Life

Key load-bearing and wear-resistant components, including the impact piston and working chisel, are manufactured from high-grade alloy steel and treated with precision thermal strengthening technology. The specialized processing greatly boosts the component hardness, compression resistance and abrasion resistance. Meanwhile, the integrated integral hydraulic sealing structure eliminates common oil leakage faults of traditional breakers, stabilizing equipment performance, lowering frequent maintenance needs and cutting long-term operational investment costs.

4. Optimized Hydraulic System for Energy Saving

The internal hydraulic pipeline of the SK81S is professionally optimized to minimize power loss during equipment operation. It can fully utilize the original power output of the matched excavator and realize intelligent automatic frequency conversion according to different ground conditions and load weights. This adaptive operation mode ensures stable running status and effectively reduces fuel consumption. Equipped with a quick-release connector, the equipment replacement process is more time-saving and labor-saving, greatly improving on-site construction efficiency.

5. Simplified Operation & Easy Daily Maintenance

This silent hydraulic hammer adopts a humanized industrial design with straightforward operation logic, requiring no professional and complex training for operators to get started quickly. The modular split structure supports convenient daily inspection, quick replacement of wearing parts and routine equipment maintenance. It greatly shortens equipment downtime caused by maintenance failures, ensures continuous and uninterrupted construction work, and improves project construction continuity.
