Sany SH500 Hydraulic Diaphragm Wall Grab

The Sany SH500 Hydraulic Grab is the industry standard for constructing deep diaphragm walls (D-walls) in challenging urban and industrial environments. Engineered for maximum verticality and efficiency, this machine is a critical asset for infrastructure projects that require stable, waterproof underground perimeters, such as metro tunnels, large-scale basements, and dam cores.

Equipped with a powerful Isuzu 6UZ1 engine and a high-strength chassis, the SH500 provides a massive 165-ton closing force, allowing it to cut through dense soil and weathered rock layers with ease. Its sophisticated real-time inclinometer and correction system ensure that wall panels remain perfectly vertical even at extreme depths. If your project demands high-productivity trenching and surgical precision, the SH500 is the ultimate foundation solution.

Key Features & Specifications:

• Extreme Depth: Capable of reaching a maximum panel depth of 80 meters.

• Unmatched Closing Force: 165 Tons of clamping power for efficient soil and rock excavation.

• Adjustable Grab Width: Versatile jaw options ranging from 600 mm to 1200 mm.

• 180-Degree Grab Swing: Superior maneuverability for working in tight corners and narrow sites.

• Verticality Control: Real-time dual-gyroscope monitoring system for precise wall alignment.

• High Efficiency: Opening/Closing cycle of just 7 seconds, maximizing hourly production.

• Stability: Specialized large-gauge telescopic chassis (100T+ operating weight) reduces vibration and ensures safety.

Ideal Applications:

• Metro & Subway Stations: Creating structural and cutoff walls for underground rail.

• Deep Basements: Building high-capacity retaining walls for skyscrapers and malls.

• Dam & Bridge Work: Seepage control and heavy-duty foundation support in water-rich soil.
