When the transmission is not in neutral,The neutral start control function prevents the engine from starting。
Throttle backup
When a Throttle Input Fault Occurs,Throttle backup provides the operator with preset engine speed control。
Throttle lock
Use the throttle lock,The operator can lock both engines at any operating level simultaneously。
Commutation management
When the engine speed is above a preset level,Shift management prevents the operator from shifting out of the neutral position。
Controlled throttle shift
The Controlled Throttle Shift function reduces the amount of fuel injected prior to shifting,Thereby prolonging the service life of the power train.。
Automatic ether starting aid
The automatic ether starting aid greatly improves cold weather starting。
Electronic Ground Shutdown Switch
Using the Electronic Ground Shutdown Switch,The operator can stop the engine from the ground by simply pressing the switch.。
Steel partition
The steel spacer plate between the cylinder block and cylinder head eliminates the need for a counterbore,Helps prevent related cracking problems。
Oil cooled piston
Oil cooled pistons and full length water cooled liners for best heat transfer efficiency,The service life of the components is prolonged。
Aftercooler
The aftercooler reduces the incoming charge air temperature in order to increase power,And reduce that possibility of causing the piston to、Thermal stress due to premature wear of piston rings and cylinder liners。
Engine oil cooler
The engine oil cooler maintains the optimum oil temperatures,For proper cooling and extended lubricant life。
Multilayer heat-insulating protective cover
Multilayer heat shields provide additional protection for the tractor by reducing the temperature of the exposed engine surfaces,It also cools the engine and engine compartment and extends the life of hoses and wiring。
Standard hydraulic retarder
Optional hydraulic retarder extends brake life。
Gearbox
The eight-speed power shift transmission provides automatic in-drive shifting,Implicity is realized、Reliable operation。
Neutral coast limiter control
When the vehicle speed exceeds 8.1 km/h(5 mph)Time,The neutral coast limiter control prevents the transmission from shifting into neutral。
Top gear control
The top gear control prevents shifting above a preset gear,So that that travel speed of the transport can be better regulate。
Electronic Programmable Transmission Control(EPTC II)
Electronic Programmable Transmission Control(EPTC II)Current and intermittent faults are logged。
Electronically Controlled Cushion Hitch
Design
Caterpillar The electronically controlled cushioning hitch is designed to cushion the impact,For a smoother ride。
Nitrogen accumulator
Nitrogen-charged hydraulic oil accumulators absorb and cushion road impact。
Buffer hook
When the electronically controlled buffer hook is locked,The cutting edge can be effectively controlled during loading and unloading。
Double kingpin design
Double kingpin design can withstand large external forces.,And simplify installation and removal。
Hook casting
Widely used steel castings eliminate weld joints in many places,Powerful hooking is achieved。
Scraper bowl
Bucket
Caterpillar The coal scoop is specifically designed for cleaning coal.。
Auger mechanism
The auger mechanism in the bucket lifts the material off the cutting edge.,And conveying the materials above the original materials;,Improved self-loading capability。
Duplex power
In all weathers and conditions.,Coal cleaning scrapers must be able to work around the clock.。
Console
Cab
Standard rubber-mounted cab reduces noise,The vibration is reduced,Allows the operator to perform operations comfortably throughout the job。
Control device
Easy to operate controls at your fingertips,Stability can be achieved、Precise operation。
Turn
Hydraulic servo steering system provides the feeling of driving a car with low effort and excellent maneuverability.。
Steering column
Tilt steering column can be adjusted to five different positions for operator comfort and control。
Chair
Suspension seats provide a comfortable driving experience。
Electronic monitoring system
The electronic monitoring system checks critical machine systems and provides three levels of warnings。
Radio
The operator station in the cab has reserved wiring for the radio。
Characteristic
657E Standard cab features include air conditioning for operator comfort and efficiency, and turn signal lights。
Serviceability
Fuel tank
Fuel tank mounted on scraper for easy access to tractor engine compartment。
Wiring harness
Wiring harnesses incorporate color coding and numbered circuits for quick identification,Also comes with at least 10 A Fuse and improved connector。
Diagnostic connector
With the help of a service tool,Starting and charging circuits can be quickly analyzed using the diagnostic connector。
O V-shaped sealing ring end face seal
O V-ring face seals help prevent oil leakage on these machine。
Centralized lubrication points
Centralized lubrication points for hitch and steering reduce lubrication times。
Repair and maintenance points
The engine service points are concentrated on the right side.,And is easy to overhaul。
Maintenance platform
Access platform and numerous handrails for ease of maintenance and safety。
Parts availability
Improved components and other Caterpillar Scraper/Commonality between machines,Improved parts availability。
Engine shutdown
Electronic ground engine shutdown provides convenient operator and service area。
Radiator
Folded core radiators allow individual folded cores to be replaced as modules,Reduced maintenance time,And that cost is reduce。
Reliability
Reducer
When the machine is operating on a steep slope,Hydraulic retarders extend brake life。
Bumper
Bumper edges are rounded,Avoid hooking into high walls。
Casting
Rack、Castings are widely used in articulated parts and bucket,A long service life is achieved.。
Wiring Harness and Hose As
The wiring harness and hose assemblies extend all the way to the tow arm,Eliminate the need for jumper lines that could reduce the efficiency of the hydraulic system。
Tire
Standard tires provide maximum buoyancy for the available option。
Scraper Power Drive Guard
Scraper power transmission guard protects the output housing、Differential cylinder and ejector cylinder,Helps minimize maintenance costs on the power train。
Multilayer heat-insulating protective cover
