Key Features
Overview
（Weichai）Optimized Engine
Low speed engine with E-fan provides increased operating efficiency Enhanced fuel pre-filter eliminates water and contaminant from fuel for best fuel system protection The air cleaner provides machine reliability even in the most severe applications
Cummins Engine
Optimized low speed torque capability and machine productivity Strong torque delivery leads to higher breakout force Best-in-class fuel efficiency
Machine Applications
The sturdy design of the SEM 656D makes it the perfect machine for port cargo handling, mineral yards, steel mills and other high demand applications In Quarry and Aggregate and Coal Mining applications the 656D can load more, move faster and burn less fuel Multiple work tools are available for increased versatility
Efficient Hydraulic System
The advanced load sensing hydraulic system with flow sharing circuits improves efficiency World Class hydraulic components ensure high reliability The optimized hydraulic system paired with the drive train reduces machine cycle time and increases productivity
Operator Station
Premium operator station with increased space and superior visibility Sliding side window and AC with fresh air circulation provide operator comfort Joystick hydraulic control for easy and precise operation Multi-function instrument dashboard with 3-level alarm Adjustable suspension seat
Reliable Drivetrain
Countershaft transmission with upgraded core components provides high reliability Large rim-pull in 1st gear and higher speed in 2nd gear provide high efficiency for load and carry applications Clutch cutoff selection switch ensures stable and safe operation The SEM designed and built axle provides best in class performance in heavy duty applications
Advanced Cooling System
The standard cooling package provides high reliability in 50℃ ambient conditions. Shock pad mounts ensure reliability under severe applications
Solid Structure
Structures undergo Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to ensure durability Performance Series (PS) buckets improve loading capability
Serviceability
Centralized lubrication points reduce maintenance time System pressure test ports are standard Easy access to external air charge connecting port Engine hood grill opens for easy service access Torque convertor is isolated from transmission making it easy to service
