• Eco Shift mode changes engine maps to reduce fuel consumption.

• Directional shift control adjusts the engine speed during directional switching to prevent damage.

• An inhibitor of increased idling on the neutral coast helps prevent a transition to a neutral position at a speed above 6.5 km / h (4 mph).

• A body shift lock helps prevent shifting above a programmed gear without fully lowering the body.

• In the event memory stored working data for access to electronic equipment. Data includes: - gear shift histograms - operator triggered events - clutch lock counter - vehicle / transmission speeding

ELECTRONIC TECHNICIAN (CAT ET)

Gain access to engine and transmission data stored in a Cat Data Link system, and display the status of all engine parameters.

CAT ELECTRONIC CONTROL SYSTEM (EMS)

Displays information on request and warns the operator of abnormal conditions using the alert system of three categories.

ADDITIONAL APPLICATIONS

Automatic deceleration control (ARC) automatically controls deceleration on a slope, maintaining ± 2,230 rpm.

The traction control system (TCS) improves performance in poor conditions under your feet by electronically controlling and controlling wheel slip.

 

An integrated brake controller (IBC) combines ARC and TCS, reducing electronic components and electrical lines.

BRAKES

1) Parking / secondary piston, 2) Working / brake piston, 3) Friction discs, 4) Steel plates, 5) Drive springs, 6) Coolant oil inlet, 7) Coolant oil outlet

BRAKES WITH MULTIPLE DISKS - EXCLUSIVE, SUSTAINABLE BRAKING AND DELAYS

Cat multi-disc brakes use constant forced oil cooling. The optional ARC and TCS use oil cooled rear brakes to improve loader performance and productivity.

REAR COOLED DISC BRAKES

Designed and manufactured for reliable, non-adjustable operation, providing superior performance and durability compared to shoe type and dry disk systems. The system combines the functions of maintenance, braking and parking brake in one device. If the pressure in the hydraulic system drops below a certain level, the secondary piston applied by the spring automatically activates the brake.

OIL FILM PREVENTS DIRECT CONTACT BETWEEN DISCS

By absorbing braking forces, cutting off oil and removing heat, this design extends the service life of the brake.

SECONDARY BRAKE

Spring-loaded, hydraulically released, oil-cooled disc brakes are located on the rear axle. Front brakes are activated as part of the secondary system, even if they are off.

PARKING BRAKES

Spring-loaded, hydraulically released parking brakes use wet disc brakes in the service system. The toggle switch activates the parking brake.

Pistons

Caterpillar`s patented two-piston design combines service, auxiliary and parking brakes, as well as braking functions.

AUTOMATIC CONTROL OF THE RETARDER (OPTION)

ARC electronically monitors braking on a slope, maintaining approximately 2230 rpm (engine rpm adjustable from 2150 to 2300 rpm in 10 rpm increments). ARC turns off when the operator presses the brake pedal or throttle.

Motor overspeed protection

When the accelerator pedal is pressed and / or the ARC function is turned off, the ARC function is automatically activated at 2475 rpm to avoid potentially destructive and often expensive engine speeding.

TRAIN MANAGEMENT SYSTEM (OPTION)

Determines whether the rear wheel slip exceeds the set limit and automatically applies the rear brakes to slow the wheel.

FEATURE OPERATOR

An indicator on the dashboard shows the operator that TCS is activated.

DIFFERENTIAL ACTION

Uses normal differential action to ensure excellent maneuvering in poor conditions under your feet. It also reduces tire wear compared to positive locking differentials used in other systems.

MOMENT

TCS divides the torque evenly to reduce the voltage generated on the main gears and axles when torque is transmitted in one direction.

SYSTEM BACKUP

If the sensors fail, normal differential action is still available to maintain steering and steering.
