Преимущества и особенности

Operator Station – Everyone can get comfortable in this cab.

All Day Comfort

The operator station on the 426 is designed to provide maximum comfort, ease of operation and all day comfort for today’s demanding operator. Designed specifically for the market, the 426 cab features a spacious interior, flat glass and excellent visibility. The cab is wider allowing the operator to freely move when turning from one mode of operation to another. Excellent ergonomics ensure that all controls are within easy reach of the operator, with a tiltable steering column and arm rests available as optional upgrades. Other features include additional storage space, large vents throughout the cab and clear gauges that provide information to the operator to help maximize the machine’s performance. Tinted glass is offered as standard to keep operators comfortable in all environments.

Power Train – Powerful performance.

Power Train

The 426 features the Cat 3054C engine (U.S. EPA Tier 2/EU Stage II equivalent) as standard and the Cat C4.4 engine (U.S. EPA Tier 3/EU Stage IIIA equivalent) as optional. The engine is a four cylinder, four stroke direct injection turbo, equipped with standard glow plug starting for optimal cold weather performance. This provides reliable starting performance down to –26° C. An optional cold weather pack is available giving reliable starting performance down to –55° C. The engine also features a gear driven water pump, providing better reliability than conventional belt driven technology.

Axle and Brakes

The 426 rear axle is an enclosed design with a wet multi-plate braking system. The system is oil immersed and self-adjusting, and allows operation in the harshest environments. The rear axle offers 100% Diff-Lock giving increased traction when working on poor ground conditions. This gives increased performance with less wear and tear to tires. The system has dual brake pedals for split braking in confined working spaces. The All Wheel Drive (AWD) is engaged via a front console panel switch or by the brake pedal during all-wheel-braking operation. The AWD can be engaged on the move, under load, in any gear and in forward or reverse. The AWD front axle is pendulum mounted and permanently sealed and lubricated, requiring no daily maintenance. A guard is available to protect the drive shaft increasing the durability of this machine when working in hard rocky environments.

Transmission

The 426 comes equipped with a 40 km/h Power-Shuttle transmission, improving roading speed and providing better spacing between gear ratios. The forward/reverse lever on the steering column is placed for easy directional changes on the move, and the gear selection is from a floor mounted shift lever.

Loader Performance – Parallel lift and superior breakout forces.

Parallel Lift

The 426 parallel lift loader boasts class leading lift capacities and breakout forces, providing more power and greater productivity. Available with General Purpose Bucket, Multi Purpose Bucket, or Multi Purpose Bucket with Forks, the 426 can be matched precisely to your needs. The parallel lift loader arms make light work of lifting and loading whilst offering excellent forward visibility along with outstanding material retention throughout the lift and lower cycles.

Ride control option offers loader suspension to improve ride comfort when moving around the job site or roading the machine. There is also the added benefit of increased material retention providing an invaluable boost in productivity.

Backhoe Performance – Versatile design for any application.

Excavator Style Boom

Caterpillar’s instantly recognizable boom is more than a cosmetic design feature, it also outperforms straight boom designs too. Whether close-up truck loading on a narrow highway or digging over obstacles such as walls, the excavator style boom outperforms the rest. Combine this versatility with powerful breakout forces and the controllability of the load-sensing, flow sharing hydraulic system and you have the best boom and stick combination in the industry. The boom is a narrow design, ensuring maximum visibility to the work tool and ground. Additionally, our system offers swing and boom cushioning as standard. This feature enables very fast trenching by damping the boom on lift. Swing cushioning enables easy spotting of the hoe over the trench to reduce cycle times and boost productivity.

Extendible Stick

The 426 is available with an extendible stick that increases dig depth and reach capability. This allows for greater machine versatility and reduces the amount of time spent repositioning the machine. A sliding inner section design helps to ensure the wear pads remain as dirt free as possible, extending adjustment and replacement intervals. One-Way or Two-Way lines, for operating hydraulic work tools, are available with the E-Stick and have been routed so that they are protected from damage when working in the narrowest of trenches.

Powerful and Efficient Hydraulics – Load-sensing system delivers improved fuel economy.

Hydraulic Performance

It’s rare that you’ll be working at full production 100% of the time, so why should the machine be working at full capacity, using more fuel, making more noise and generally increasing wear and tear on key components? The 426 has a load-sensing, closed center hydraulic system, which is designed to closely match power and flow to the demand needed by the operation. This works to both increase fuel efficiency and decrease wear and tear.

So whether you’re in full trenching mode, or delicately digging around services, you are always in total control. In applications such as loading and carrying, speed is important. The system will match the flow needed to get the job done quickly and efficiently. As there is minimal demand on the system unless needed, there are less parasitic horsepower losses and more power available for rimpull which means better loading and roading performance.

The 426 also features flow-sharing hydraulic valves, ensuring that the correct flow of oil reaches the implement cylinders, providing greater control and eliminating oil starvation when operating multiple functions, such as grading with the backhoe.

Serviceability – Easy service to keep your machine working.

Easy Access

Daily checks that can be time consuming for a busy operator are kept to a minimum on the 426. The 426 is equipped with a flip open hood, allowing access to all the check and fill points, air cleaner, washer bottle and visual check indicators. The 426 offers a clear bowl precleaner, designed especially for the tough environments that this machine operates in giving extra protection to the engine. This is located on top of the hood and gives a visual indicator to the operator that it needs to be emptied, allowing the operator to keep everything clear of debris and the system running cool. The 426 carries on the Cat backhoe loader tradition with sealed for life axle oscillating pins, axle and driveshaft U-joints. Cat Product Link system provides remote reporting of machine location and hours.
