Discover the Robust SANY SY155H excavator, a 15-ton-class hydraulic excavator featuring an 84 kW Isuzu engine, 0.65 m³ bucket, innovative electro-hydraulic control, and built-for-comfort cabin.

Overview

O SANY SY155H excavator is a robust 15-ton hydraulic powerhouse, tailored to excel in heavy-duty construction, urban development, and demanding excavation tasks. It’s driven by an 84 kW Isuzu 4JJ1 engine (displacement 2.999 L), delivering dependable torque and fuel efficiency—optimized for long-lasting performance in harsh environments.([turn0search0]) The SANY SY155H excavator, weighing approximately 14.1 T, strikes a compelling balance between strength and maneuverability—especially effective in confined job sites. Its 0.65 m³ bucket matches a formidable 103 kN bucket digging force, enabling it to handle significant material loads with ease. Paired with a cutting-edge electro-hydraulic control system, the machine maintains maximal power delivery while reducing energy loss.

Innovative Features

• Electro-Hydraulic Control System: Utilizes a dual-pump, dual-circuit constant power model to minimize power loss and maintain balanced output under load changes.
• Multi-Function Design: Equipped with quick-change pipelines and dual auxiliary hydraulic lines, supporting varied attachments for versatility on diverse tasks.
• Ultra-Flexible Operations: Its ultra-small turning radius allows a full 360° bucket rotation within just 3.7 m width—ideal for narrow urban, landscaping, or municipal works.
• Automatic Air Conditioning: The standard HVAC system maintains a fresh and comfortable cabin climate year-round with swift temperature adjustability.
