SH520

🏗️ SH520 Heavy-Duty Crawler Excavator · Core Product Advantages

The SH520 is a 50-ton class titan engineered for the most demanding mining and heavy-duty excavation projects. Featuring a premium Linde hydraulic system and high-tensile structural reinforcements, it represents a significant leap in both operational efficiency and durability.

⚙️ Elite Cummins QSM11 Powerhouse

Driven by the Cummins QSM11 engine delivering a massive 280kW of power, the SH520 utilizes an electronic high-pressure fuel injection system. This ensures optimal combustion, high torque at low speeds, and a significant reduction in fuel consumption, making it a leader in power-to-weight efficiency.

⛏️ Massive Digging Force & Bucket Capacity

With a bucket capacity reaching up to 3.5m³ and a bucket digging force of 292kN, the SH520 is designed to move more material in less time. Whether excavating hard rock or managing large-scale earthwork, its superior cutting force ensures maximum cycle-time efficiency.

💧 Precision Linde Hydraulics & Toshiba Control

The integration of a Linde load-sensing system and Toshiba main valves provides unmatched control. Features like "Boom Priority," "Swing Priority," and "Bucket Regeneration" allow for fluid, synchronized movements, ensuring that power is delivered exactly where it’s needed while reducing energy waste.

🛠️ "Central Load-Bearing" Reinforced Structure

The SH520 features a "Central Load-Bearing Structure" that transmits forces directly to the chassis, reducing structural stress. The reinforced "X" type travel frame offers 35% higher sectional strength than traditional models, providing a rock-solid foundation for high-load operations in rugged terrain.

🔋 Smart Efficiency & Multi-Mode Operation

Equipped with three optimized work modes, the SH520 allows operators to adapt performance to the task at hand. The auto-idle function drops engine RPM during periods of inactivity, further lowering fuel costs and ambient noise levels on the job site.

⚙️ Cummins Engine: Reliable, Efficient, Low Fuel Consumption

1. Utilizes an electronically controlled high-pressure fuel injection system to optimize the injection process and reduce fuel consumption.

2. Synchronous control reduces redundant engine speeds under light-load conditions, lowering both fuel costs and noise levels.

💧 Series Main Pump Characteristics

High efficiency, rapid response, and high power output density. The pump features versatile control methods and strong self-priming capabilities for maximum reliability.

🕹️ Toshiba Main Valve Features

Includes advanced circuits for straight-line travel, boom priority, swing priority, and bucket confluence. It also features bucket and boom regeneration systems as well as load-holding valves for precise and safe operation.

🏗️ SH520-9 Reinforced Working Equipment

🛠️ Heavy-Duty Boom & Arm

1. High-tensile strength steel plates used in high-stress areas.

2. Forged components utilized at axis-seat positions for superior durability.

3. Middle sections feature large-section partition welding for structural integrity.

🏢 "Central Load-Bearing" Upper Structure

The "Central Load-Bearing Structure" transfers operational forces directly to the undercarriage, significantly reducing internal stress and extending the overall lifespan of the machine.

🛤️ Reinforced "X" Type Travel Frame

The cross-beam structure has been re-engineered for stress concentration areas, increasing sectional strength by more than 35% compared to conventional models.

⛏️ Reinforced Heavy-Duty Bucket

Wear-prone areas (front, sides, and bottom) are reinforced with ultra-wear-resistant welding plates. The average lifespan of the bucket is extended by more than 20% compared to standard models.
