SEM658D

Reliability: Sturdy frame design for heavy duty, Caterpillar design EH transmission and made in house axle make usage life longer Productivity: EH control transmission with KD and auto speed function, optimized TC and engine match 8% rimpull improved
Fuel Consumption: Optimized transmission flow save fuel, E-fan and single load sensing hydraulic system make lower fuel consumption
Comfortable: Good visibility, low noise design with first class premium 5 direction adjustable seat make operation comfortable

E-fan make fuel consumption better, 3 speeds auto-selection depend on coolant temperature
3 stages air cleaner with 93% efficiency pre-cleaner reduce earlier wearing, high efficiency fuel filter make engine work in good condition
Cat technology damping mount reduce vibration failure. Four air valves delivers robust power
Radial seal air filter makes the maintenance easier and with good reliability

Single load sensing system, high productivity and high fuel efficiency
Piston pump, lower heat load contribution and provide more rim pull when hydraulic partial working
Less hydraulic oil capacity required because provide flow depends on demand

Mould formed cab with all trims design and more vents with HVAC make operator feel better
First class premium seat with suspension adjustable, arm rest and safety belt. Up-down, forward and reverse adjustable
Caterpillar method design damping mount reduce vibration failure
Slide window, fresh air inlet system make environment better

High performance aluminum cooling package suitable for most severity applications
Oil cooler and radiator parallel design can balance heat load inside and suitable diversity applications
Damping design reduce vibration failure
High ambient 50°C cooling package make machine reliability better

Validated by Cat method FEA (Finite Element Analysis) and OMSA (On Machine Stress Analysis)
Middle articulation frame less work space needed, reduce tire wearing and fuel consumption
Large thread design in articulation section improves load capacity

Quick pressure test ports on hydraulic (SOS) and brake air lines make diagnose easier
Large wing hood door make service easier, approach to air cleaner, fuel filters and oil filters
Large thread design in articulation section make operator easier to approach
Air tank with pressured air tap provide more convenience for service and maintenance

Landscaping, building, sewer/water tie-in, local utility construction Ready mix cement/concrete products, quarry/stone, clay, recycled aggregate, sand and gravel
