The strong, durable Cat ACERT™ engines with the Tier 4 Interim/EU Stage IIIB exhaust emission solution and electronically controlled smooth shifting transmissions deliver high productivity with low fuel consumption. There are signifi cant changes/improvements to the engine/transmission software that result in smoother gear changes.

Engine With Cat® C15 ACERT™ Technology

ACERT Technology

The Cat® C15 ACERT™ engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability.

Cat Clean Emissions Module (CEM)

CEM is an exhaust aftertreatment package consisting of a diesel particulate filter and control systems. The CEM reduces particulate emissions using passive and active regeneration

during normal engine operation.

Cat NOx Reduction System (NRS)

The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Fuel Delivery

Mechanically actuated Electronic Unit Injection (MEUI-C) multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.

Diesel Particulate Filter Regeneration

Regeneration

Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) is used to regenerate the DPF. The DPF traps both particulates and ash, the ash is removed at regular service intervals.

Modes of Regeneration

When set to automatic, regeneration will occur without any interaction from the operator. The three modes of regeneration shown below allow the articulated truck to adapt to specific

site conditions in the most efficient manner.

Automatic “On-the-go” regeneration is initiated when the engine control module determines conditions are acceptable. The articulated truck is not required to stop working.

Automatic: Low Idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time.

Manual: A manual regeneration is initiated by pressing the regeneration switch for 5 seconds. The machine must be brought to a non-operating mode in order to perform

a manual regeneration.

Transmission

Electronic Transmission

The Cat seven-speed forward and two-speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission features enhanced shift control logic with anti-hunt shift strategy for speed continuity, and to ensure constant shift times.

Min-max Governor Control

ECPC control is matched to the min-max governor control for precise smooth shifting.

Two Reverse Gears

The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications.

Smooth Transmission Gear Shifting – Shift Torque Management (STM)

The 735B features ECPC Shift Torque Management (STM), with improved Shift Control Logic (SCL) and Part Throttle Shifting (PTS). These features allow smoother shifting and greater acceleration on grades while torque is maintained throughout the shift changes. SCL also provides automatic shift selection that is more specific to the desired machine operation, and downshifts when needed for maximum acceleration when increased throttle is applied. PTS allows shifting at lower speeds during part throttle operation, resulting in improved fuel economy, quieter machine operation, and better maneuvering in reduced speed operating conditions.

Suspension and Automatic Traction Control (ATC)

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 purpose designed for tough applications and offer a soft, smooth ride.

Rear Suspension

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

Automatic Traction Control

Fully Automatic Traction Control (ATC). Inter-Axle- Differential lock (IAD) and Cross-Axle-Differential locks (XAD) feature oil immersed clutches that require no operator input. Operation is seamless and smooth, and it eliminates wheel slip for maximum traction.

Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions.

Fully automatic, independent, IAD and XAD clutches are engaged on-the-go to optimize machine performance and control in all conditions. Clutches are automatically disengaged when ground conditions dictate, maximizing efficiency when steering or on uneven ground.

ATC eliminates wheel spin in soft under foot extreme ground conditions where little traction is available. It also reduces tire and driveline abuse eliminating lost effi ciency caused by improper manual operation of the differential clutches.

Retardation Control

The Cat engine compression brake control lever is positioned on the right-hand side of the steer column.

Four modes of operation with three steps of retardation, provide an optimum match between operating conditions and retarding power.

Operator Comfort

RideComfort

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.

SpaciousTwo-PersonCab

The 735B features a large two-person cab, offering comfortable working space for both the operator and passenger. The 735B, 740B and 740B EJ articulated trucks use the same spacious cab design.

AirSuspensionSeat

The air suspension seat enhances 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.

PassengerSeat

Full-size passenger seat features a fully padded seat with a backrest and a wide, retractable seatbelt for a secure and comfortable ride. The passenger seat is positioned next to the operator seat, giving both the operator and passenger a clear view of the instrument panel, controls and the road.
