BIẾN MÔ

Biến mô với đường kính lớn hơn, được cấu hình cho các ứng dụng bên ngoài đường cao tốc, cho phép truyền công suất động cơ cao hơn một cách hiệu quả hơn tới hệ thống truyền lực thấp hơn

AUTOMATIC TRACTION CONTROL (ATC)

The ATC system successfully introduced on the B Series has been further enhanced for even better performance. Application of the inter and cross-axle differential locks is ‘on-the-go' and fully automatic. The operator does not have to think about when and where to engage either diff lock. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and therefore productivity. Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or on uneven ground. ATC reduces tire and driveline abuse, eliminating lost efficiency caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.

AUTOMATIC RETARDER CONTROL (ARC)

In automatic mode, use of the retarder is much easier for the operator. As with ATC a number of machine operating aspects are monitored, and if required the engine compression brake is engaged automatically. The system can help towards eliminating engine overspeed, improving safe machine operation and reducing cycle times, yet still with the flexibility of manual control if needed.

FRONT SUSPENSION

The three-point front suspension oscillates ±6° to provide a smooth ride, allowing the operator to travel at speed over rough terrain and softening impact loads on structures and components. Large bore, low-pressure cylinders are purposely designed for tough applications and offer a soft, smooth ride.

A-FRAME CONSTRUCTION

The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement and stability.

REAR SUSPENSION

Features a walking beam with Caterpillar designed rear suspension mounts, which have long life and provide a reliable, and stable ride for excellent load retention.

MOUNTING POINTS

Suspension mounting points are integrated into the axle housing, increasing reliability.

ALL AXLE ENCLOSED WET BRAKES

Provide smoother retarding and braking, with improved holding in slippery conditions and on grades.

HILL ASSIST

Eliminates potential ‘roll-back' on grades. If an operator stops the machine on a grade, when taking his foot off the service brake pedal the machine will automatically hold the service brakes on for a number of seconds to prevent the machine from rolling backwards.

RIDE COMFORT

The three-point front suspension with its oscillating axle and low-pressure ride struts, combined with the center-mounted cab, offers unrivaled levels of ride comfort for the operator in all driving conditions. The operator remains comfortable and productive throughout the day.

SPACIOUS TWO-PERSON CAB

The large two-person cab, offers a comfortable working space for both the operator and a passenger. The passenger seat is fully padded with a backrest and a wide, retractable seat belt for a secure and comfortable ride. It is also positioned adjacent to the operator, giving both the operator and passenger a clear view of the instrument panel, controls and the road. The storage space behind the operator seat has been increased, and access improved. The design and layout is common across all C Series Articulated Trucks.

AIR SUSPENSION SEAT

The air suspension seat provides improved operator comfort with a cushioned upper high back, adjustable damping with three settings, ride zone indicator and adjustable lumbar settings. It is fully adjustable to provide the optimal driving position.

CAB ATMOSPHERE

The air conditioning system helps to keep you comfortable whatever environment you are operating in.

WAITING BRAKE

As the name implies, anywhere you are waiting you can use this feature to remove the need for repeated application of the parking brake. For example, if you are holding the machine on a grade, in a loading or dump area, select neutral and press the yellow button on the gear select cane. This will automatically apply the service brakes, without the need to apply the park brake. To disengage, put the machine in gear and the brakes are automatically released.

CONTROL LAYOUT

The cab is designed to make all aspects of machine operation as simple as possible. The controls and gauges are easy to read and straightforward to operate, the controls and gauges allow the operator to focus on safe machine operation while maintaining productivity.

DASHBOARD

The integrated wrap-around dash puts all controls within easy reach of the operator. Featuring LED illuminated rocker switches for the dash dimmer, rear wash wiper, hazard warning, work lamp, secondary steer, A/C and cigar lighter. Delivers an automotive feel with the industrial strength you would expect from Caterpillar.

COLOR MULTI PURPOSE DISPLAY (CMPD)

The dash mounted display unit shows the operator various levels of performance and condition pages as well as machine warning categories. These include performance data, configuration settings, operator and machine totals, service information, various machine status parameters, machine payload Information (when fitted), and the video feed from the rearview camera.

BLUETOOTH™ STEREO CONNECTIVITY

Make and receive calls via Bluetooth equipped mobile.

FRONT FRAME

The front frame design features a large box section and wide, stiff frame beams to handle torque loads. The divergent frame design decreases stress in the hitch area and optimizes suspension geometry. The frame design makes maximum use of robotic welding for increased durability.

REAR FRAME

Twin-box construction minimizes stress concentrations and provides low weight with long service life.

SUSPENSION

The three-point oscillating axle front suspension provides unparalleled ride quality. It also protects the truck from adverse road conditions by absorbing shock loads that would reach the frame.

ARTICULATING/OSCILLATING HITCH

The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.

HITCH CONSTRUCTION

Field proven two-piece construction features a durable cast steel head bolted to a hard wearing forged steel tube.

DUMP BODY DESIGN

The 745C has a large target area to provide consistently high load-carrying capacity. Its diverging flow design gives clean material discharge, which maximizes production and avoids the waste of carry-back.

OUTPUT TRANSFER GEAR

Distributes drive to the tractor and trailer and includes a wet clutch differential lock for optimum traction in poor underfoot conditions.

SERVICE BRAKES

Dual-circuit, all wheel braking system. The full power hydraulic system actuates enclosed, oil immersed, multi disc, multi plate brakes with independent front and rear circuits and accumulators.

PARKING BRAKE

Located on the center axle in an elevated position, it is spring applied and hydraulically released.
