Caterpillar WHEEL TRACTOR SCRAPERS 637G - catalog of spare parts

 

DUAL ENGINES

 

Double engines allow scrapers to work in a coal tank to achieve maximum payload and provide fast cycle times.

FOUR-WHEEL DRIVE

All-wheel drive allows the machine to work effectively in bad conditions under their feet and climb piles of slippery, loose coal.

GREAT POWER COALS

Coal bowls are longer and taller than standard scraper bowls, which allows you to carry 50 cubic yards (38 cubic meters) using the 637G.

POSSIBILITY OF PACKING

The coal bowl scrapers are effective for compacting coal, which reduces the risk of coal self-ignition in storage by eliminating airspaces.

COAL STOCK CONSTRUCTION

Scrapers for coal bowls allow you to create coal reserves by self-loading coal in the receiving area, moving it to the storage area and unloading coal into thin lifts.

ENGINE

Cat proven engines provide increased power and torque for superior traction in heavy load conditions.

FUEL SYSTEM

The fuel system and the electronic control unit on the engine of the C18 tractor economically and accurately deliver fuel.

INJECTION PRESSURE

High injection pressure, independent of engine speed, reduces smoke and emissions while improving response.

VARIABLE TIME INJECTION

Variable injection times and durations improve fuel efficiency and cold start, reduce smoke and emissions.

FORM SPEED INJECTION

Forming injection speed reduces engine emissions and noise.

MECHANICAL PARTS

Fewer mechanical parts in the fuel system increase reliability.

ELECTRONIC CONTROL

Electronic control provides automatic height reduction and automatic limitation of the air filter.

RATINGS OF SEVERAL HORSES

Rated power in several horsepower limits power in the first and second gears, if the operator does not operate the auger or elevator.

NEUTRAL START CONTROL

Neutral start control prevents the engine from starting if the gearbox is not in neutral.

RESERVE MANAGEMENT

Backing up the throttle provides the operator with pre-set engine speed control in the event of a throttle inlet failure.

BLOCK

Throttle lock allows the operator to block both engines at any operating level.

DIRECTED SHIFT MANAGEMENT

Directional shift control prevents the operator from switching from neutral when engine speed is above a predetermined level.

DRIVED ENGINE MOTION

Controlled throttle shifting increases transmission life by reducing fuel injection speed just before shifting.

AUTOMATIC OTHER START

An automatic auxiliary launcher of the ether significantly improves the launch in cold weather.

DISABLE EARTH ELECTRONIC LEVEL

Electronic trip at ground level allows the operator to stop the engine from the ground with a flick of a switch.

STEEL SPACER PLATE

A steel spacer plate between the block and the head eliminates the need for countersinks and helps prevent cracking problems.

COOLING OILS

Oil-cooled pistons and full-size water-cooled sleeves maximize heat transfer for longer component life.

subcooler

An additional cooler reduces the intake air temperature to increase power and reduce thermal stresses, which can cause premature wear of pistons, rings and liners.

ENGINE OIL

The engine oil cooler maintains the optimum oil temperature for proper cooling and longer lubrication life.

LAMINATED THERMAL PROTECTION

Laminated heat shield improves the protection of the tractor by reducing the temperature of the open surfaces of the engine, cools the engine and working compartments, increases the service life of hoses and wiring.

Direct fuel injection system

Direct injection fuel system without adjustment with separate pumps and injection valves.

ADDITIONAL HYDRAULIC RETARDER

An optional hydraulic retarder can extend brake life.

TRANSMISSION

An eight-speed, power shift transmission provides automatic on-the-go shifting for easy, reliable operation.

NEUTRAL CONTROL OF THE COAST INHIBITOR

Controlling a neutral coast inhibitor helps prevent shifting to a neutral gear at speeds above 8.1 km / h (5 mph).

TOP GEAR CONTROL

Top-drive control helps prevent shifting above the programmed gear in order to better control the speed on the road.

ELECTRONIC PROGRAMMABLE TRANSMISSION CONTROL (EPTC II)

Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.

DESIGN

The electronically controlled Caterpillar shock absorber design absorbs shocks, ensuring a smooth ride.

NITROGENIC BATTERIES

Nitrogen and oil batteries absorb and dampen road bumps.

CASTLE PILLOWS PILLOWS

The electronically controlled suspension is locked to provide positive control of the cutting edge during loading and unloading.

DOUBLE DESIGN KINGBOLT

The double king-bolt design withstands heavy external loads and makes it easy to install and remove.

CONNECTIONS

The extensive use of steel castings eliminates many welded joints, making a strong hitch.

A BOWL

Caterpillar Coal Scraper bowls are shipped from a plant that is specifically designed to process coal.

Auger Mechanism

The screw mechanism in the bowl improves the load capacity by lifting the material from the cutting edge and transferring it to the top of the load.

TANDEM POWER

The scraper for processing coal should work around the clock, in all weather conditions.

TAXI

A standard rubber cabin reduces noise and vibration for comfortable work during a shift.

CONTROL

Easy control is easily accessible for precise and precise control.

STEERING

Hydraulic servo-steering system provides light car feel and excellent maneuverability.

STEERING COLUMN

The tilt of the steering column is adjustable in five different positions for operator comfort and control.

SEATS

The suspension seat provides a comfortable ride.

ELECTRONIC MONITORING SYSTEM

The electronic monitoring system checks important systems of the machine and issues a three-level warning.

RADIO

The operator station includes radio compatible wires in the cockpit.

FUEL TANK

A fuel tank mounted on the scraper improves access to the tractor`s engine compartment.

WIRING HARNESS

The improved wiring harness includes color and numbered circuits for quick identification, fuses of at least 10 A and improved connectors.

DIAGNOSTIC CONNECTOR

Diagnostic connector with a service tool allows you to quickly analyze the circuit start and charge.

Sealing rings

O-rings help keep these machines dry.

CENTRALIZED LUBRICANTS FOR LUBRICANT

Centralized lubrication units for coupling and steering reduce lubrication time.

SERVICE POINTS

Engine service points are grouped on the right side for easy access.

SERVICE PLATFORMS

Service platforms and multiple handrails improve access and security.

AVAILABILITY OF PARTS

Increasing the commonality of components with other Caterpillar scrapers / machines increases parts availability.

ENGINE DISCONNECTION

Electronic engine shutdown at ground level for convenient operator and service area operation.

RADIATOR

The radiator with a folded core allows you to replace individual cores in the form of modules, which reduces time and maintenance costs.

ADDITIONAL RETARDER

An additional retarder prolongs the service life of the brakes when working on heavy slopes.

BUMPERS

The rounded sides reduce grip on high walls.

Casting

Extensive use of castings in the frame, sample and bowl provides a long service life.

WIRING HARNESS AND HOSE ASSEMBLIES

Wiring harnesses and hose assemblies are lowered through the traction arms, eliminating the need for a “skipping” line, which can reduce the efficiency of the hydraulic system.

TIRES

Standard tires provide maximum throughput of the available options.

SCRAP DRIVE PROTECTION

The universal joint scraper protection protects the output housing, the differential and the ejector cylinder, which helps minimize transmission maintenance costs.

LAMINATED THERMAL PROTECTION

A laminated thermal shield helps maintain the surface temperature in the engine compartment below the flash point of diesel fuel.
