CAT - ARTICULATED TRUCKS 740 B EJECTOR



ARTICULATED TRUCKS 740 B EJ

The new Cat® 740B EJ with 38 tonnes (42 tons) rated payload offers proven reliability and durability, high productivity, superior operator comfort and lower operating costs.

The spacious two-person cab with forward facing passenger seat and off road oil/nitrogen front suspension cylinders keep the operator comfortable through out the working day.

The true “on-the-go” Automatic Traction Control (ATC) automatically modulates the correct level of Inter-Axle and Cross-Axle differential lock engagement which will improve cycle times and productivity. No operator interaction.

Strong, durable Cat ACERT™ engines with the Tier 4 Interim/EU Stage lllB exhaust emission solution and electronically controlled smooth shifting transmissions deliver high productivity with low fuel consumption. There are signi_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. 

SteeringColumn
A comfortable driving position is provided by a telescopic and tilt adjustable steering column.

  • Ease of Operation
Ergonomic Layout
The controls and layout of the cab are designed to make it as easy to operate as your car. Quick, easy to read and simple to operate, the controls and gauges on the 735B allow the operator to concentrate on production.

Color Multi Purpose Display (CMPD)
A multi screen display unit showing various levels of machine warning categories, performance and condition pages, including: Performance, Settings, Totals, Service, Machine Status, Operator, and Rearview Camera.

Warning Categories
The monitoring system provides four warning categories.

The first warning category requires only operator awareness.

The second warning category requires a change in machine operation or maintenance to the system.

The third warning category requires an immediate change of the machine operation.

The fourth category requires the operator to immediately stop the machine. The fourth category also requires the operator to immediately shut down the engine.

Viewing Area
The low sloping hood and placement of the cooling package behind the cab give the operator excellent all-around visibility. The large glass area and central operator position also provide excellent visibility.

Transmission and Hoist Levers
The hoist lever provides easy, comfortable operation. The transmission lever offers excellent comfort, and control for top gear limit, transmission hold and neutral lock.

  • Ejector Body
Ejector
The ejector body offers clean load ejection and the capability to work in areas with restricted overhead clearance and soft
underfoot conditions.

Versatility
The 730 Ejector shares the versatility of the Standard 730 Articulated Truck, operating in the same conditions, but offering unique capabilities that stretch the operation
envelope.

Spreading
The truck can eject and spread the material while moving, reducing additional spreading and dozing equipment. “On‑the-go” ejecting results in faster cycle times and reduced power train loads.

Stability
Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes and in very soft underfoot conditions especially on landfill sites.

Overhead Clearance
The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.

Carry-Back
The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.

Body
Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 450 on the base and Brinell 400 on the sides) that provides exceptional durability. Ejector top rails are made from high-strength alloy steel. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in) in diameter.

Blade
The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.

Cylinder
A three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.
