YOUR MACHINE – YOUR SUPPORT
MACHINE SELECTION Your dealer can help you with your machine purchase decision, based on your requirements and help keep operating costs to a minimum. Is the machine you have in mind exactly the best for your job, or could there be a more suitable solution?
POWERFUL LOAD SENSING HYDRAULIC SYSTEM
FLOW-SHARING VALVES Actively manage the flow of oil between each function of the machine. When the operator demands multiple operations the machine responds, providing smooth, effortless operation.
VARIABLE DISPLACEMENT PISTON PUMP A high capacity variable displacement piston pump allows for perfect matching of power and operator demand, providing power when it is needed whilst contributing to great fuel economy.
MORE LIFTING PERFORMANCE The option of a larger boom cylinder is available on the 428 giving increased lifting performance against the standard boom cylinder. This option is available with either mechanical or pilot controls.
BACKHOE – BUILT FOR THE TASK
HIGH-ROTATION LINKAGE The Cat backhoe linkage provides an industry-leading 205 degrees of bucket rotation. This design helps with material retention when truck loading and with vertical wall-trenching. Improved performance and efficiency are achieved by the ability to do more with less movement.
EXCAVATOR-STYLE BOOM Whether close-up truck loading or digging over obstacles, the iconic excavator-style boom tackles the toughest jobs with ease. Combine this versatility with powerful breakout forces, controllability, a powerful hydraulic system and the 428 is capable of high levels of productivity with minimum effort. The boom is a narrow design, ensuring maximum visibility to the attachment and ground.
CAT CUSHION SWING The standard Cat Cushion Swing System smooths the backhoe swing function when returning to the trench. Operators will immediately appreciate being able to line up the bucket edge on the trench wall faster and with more control.
SIDE SHIFT FRAME The Side Shift Frame has exterior lock clamps, with no disassembly needed when servicing. The frame is a solid design with E-Coat protection preventing material build up in the frame, reducing the risk of rust and increasing the life of the frame.
EXTENDIBLE STICK The extendible stick comes as an option for applications where more versatility is needed. Increasing dig depth and reach capability by 922 mm reduces the amount of machine repositioning and therefore reducing site damage and increasing productivity. A sliding inner section design helps to ensure the wear pads remain as dirt free as possible, prolonging adjustment and replacement intervals. Auxiliary lines, for operating hydraulic attachments, have been routed so that they are protected from damage when working in the narrowest of trenches.
POWERED SIDE SHIFT (OPTIONAL) Available as an option either from the factory or as a dealer fitted kit, the powered side shift solution provides a hydraulic service to allow the operator to easily position the backhoe across the full width of the Side Shift Frame. Ideal for use in areas with minimal space and utility applications such as gas, electrical, and telecoms.
POWER TRAIN – POWERFUL, PROVEN AND EFFICIENT
C3.6 ENGINE The Cat C3.6 engine, which meets EU Stage V standards, reduces owning and operating costs while maintaining the same performance and power as the C4.4 engine. The aftertreatment is a compact, maintenance-free solution of DOC, SCR and DPF. The Cat C3.6 engine is a turbocharged in-line four-cylinder, four-stroke cycle with direct injection diesel engine. Cold starting capability down to –25˚C comes as standard with a cold starting package option allowing the machine to start down to –47˚C. This engine has a 12 volt starting motor with a 750 CCA maintenance-free battery. This engine gives up to 10% fuel savings, based upon application and machine setting, compared to the C4.4 engine.
POWER MANAGEMENT MODES Three power management modes are available: Eco, Standard and Standard Plus. Depending upon application or performance needs, the operator can select the mode that gives optimum results. Eco mode limits both pump flow and engine speed giving higher fuel saving benefits whereas Standard Plus gives maximum pump flow and engine speed, providing increased power and performance where needed.
TRANSMISSIONS The 4-speed manual transmission is standard on the 428. A 4-speed powershift transmission is available as an optional upgrade. Improved operator comfort and reduced fatigue is achieved by operation through the directional control lever, rather than floor mounted lever, to shift gears. For those operators doing a lot of roading the autoshift transmission with lock-up torque convertor is an ideal option as it can give up to 15% fuel efficiency savings on the road whilst maintaining travel speed in hilly environments.
AXLES AND DIFFERENTIAL LOCK Heavy duty axles and a 100% locking rear differential come as standard on Cat backhoe loaders. The axles provide high durability whilst providing superb traction on uneven surfaces. No daily greasing is required on the front axle helping to save both time and money, keeping owning and operating costs as low as possible. The Diff-lock improves performance by giving maximum traction in all conditions.
LOADER PERFORMANCE – MAKING LIGHT WORK OF LIFTING AND LOADING
PARALLEL LIFT Parallel lift loader arms offer excellent forward visibility and self-leveling, ensuring excellent material retention throughout the lift and lower cycles.
RIDE CONTROL This option offers loader suspension to improve operator comfort and productivity. When moving around the job site or transporting the machine on the road, ride control provides extra stability which creates an easier ride for the operator and helps material retention to improve operator efficiency.
RETURN TO DIG Return to Dig allows the operator to return the bucket to a preset level, this is great for applications with repetitive work cycles especially when working with forks. When not required, for instance when grading with the loader bucket, Return to Dig can be turned off within the display screen.
IT QUICK COUPLER This option is available from the factory or as a kit, providing the extra versatility needed when working in multiple applications. This coupler allows a quick and safe change between multiple attachments from the inside of the cab.
THE CLASS LEADING OPERATOR ENVIRONMENT JUST GOT BETTER – SET YOUR MACHINE PERFORMANCE TO INCREASE PRODUCTIVITY AND EFFICIENCY
LCD OPERATOR DISPLAY The LCD operator display comes standard as a softkey display or can be upgraded to touchscreen. Through the interactive display you can get updates on machine diagnostics and upcoming service intervals, as well as being able to configure various performance parameters dependent on configuration. This helps to match machine performance to operator preference further increasing productivity and efficiency. Optional machine security system is embedded into the display screen helping to keep your Cat backhoe loader secure.
OPERATOR COMFORT To reduce operator fatigue and increase efficiency, the air suspension seat comes as standard with switches and controls being ergonomically located within reach of the operator. Diff-Lock button, Transmission kickdown and auxiliary controls are all located on the loader control joystick giving power and control at the operator’s fingertips. Great visibility allows the operator to get the job done in a safe and efficient manner.
HOE PILOT CONTROLS Hoe Pilot controls are available as an option on the 428. These are mounted on fully adjustable pods that the operator can position to their preference. These controls increase operator comfort by having them located in the most ergonomic position as well as being easier and smoother to operate than the standard mechanical controls. The loader control will remain mechanical.
