The EQB210-20 diesel engine is a robust power solution specifically designed for crane and lifting equipment applications. With an output of 210 horsepower, this engine delivers strong torque, smooth power response, and reliable endurance, making it well suited for truck-mounted cranes, mobile cranes, and other heavy lifting machinery.
Crane operations place unique demands on engines, requiring stable output, precise power control, and consistent performance under high load. The EQB210-20 is engineered to meet these requirements while maintaining fuel efficiency and long service life.
FEATURE 01
Torque-Oriented Performance for Lifting Tasks
FEATURE 02
Reliable Operation Under Continuous Load
FEATURE 03
Fuel Efficiency and Operating Cost Control
Unlike high-speed transport vehicles, cranes rely heavily on low- and mid-speed torque to support lifting, slewing, and hoisting operations. The EQB210-20 is calibrated to provide strong pulling power at low RPM, ensuring smooth crane movements and precise load control.
This torque-focused output helps reduce sudden power fluctuations, improving operational safety and minimizing stress on hydraulic systems and drivetrain components.
During lifting operations, crane engines often run at steady speeds for extended periods while powering hydraulic pumps and auxiliary systems. The EQB210-20 diesel engine maintains stable combustion and consistent output under continuous load, reducing overheating risks and improving overall system reliability.
Its balanced performance supports long working shifts without sacrificing engine stability or efficiency.
Fuel consumption is a major consideration for crane operators, especially on long-term construction projects. The EQB210-20 uses an optimized fuel delivery system that improves combustion efficiency, allowing operators to achieve reliable lifting performance without excessive fuel usage.
Lower fuel consumption directly contributes to reduced operating costs and improved project profitability.

Emission control involves knowledge of catalytic chemistry. To meet increasingly stringent emission regulations, engines require effective emission control technologies. Catalytic converters are commonly used emission control devices that utilize catalysts to convert harmful gases emitted by the engine, such as carbon monoxide, hydrocarbons, and nitrogen oxides, into harmless carbon dioxide, water, and nitrogen. The application of catalytic chemistry in emission control mainly includes catalyst selection, research into catalytic reaction mechanisms, and catalytic converter design. Different catalysts exhibit different catalytic activities for different harmful gases, necessitating the selection of appropriate catalysts based on the engine's emission characteristics. Simultaneously, studying the catalytic reaction mechanism can optimize the design of the catalytic converter, improving its catalytic efficiency and lifespan.
