Move more while consuming less fuel
C18 Cat Engine The Cat C18 engine has been designed and tested to meet your most demanding applications. Three options for the C18 engine are available on this machine: American EPA Tier 4 Final/European Stage IV standard with aftertreatment, Tier 3 equivalent engine without aftertreatment, or Tier 2 equivalent engine without aftertreatment. The fully integrated electronic engine controls work in conjunction with the entire machine for increased fuel efficiency. The engine idle shutdown feature reduces fuel consumption at idle. The engine delayed shutdown feature ensures longer lifespan. Cat Planetary Powershift Transmission The all-new transmission controls with Advanced Productivity Electronic Control Shifting (APECS) provide extra boost on slopes and save fuel by pulsing during gear shifts. Impeller Clutch Torque Converter (ICTC) This device allows drivers to optimize efficiency by varying the effort at the machine rim while increasing hydraulic power. Reduced tire wear. Full throttle gear shifts for shorter cycle times. Smooth approach to the dumping area to limit spillage and ensure shorter cycle times. Cat Lock-Up Torque Converter Eliminates torque converter losses while reducing circuit temperature. Improves travel speeds. Reduces cycle times in loading and hauling applications. Improved Hydraulic Efficiency New flow distribution system and variable displacement, load-sensing piston pumps. Hydraulic flow now available on demand for better energy efficiency.
Value and long-term longevity
Robust Structures Boost your results with ultra-resistant structures capable of ensuring multiple lifecycles and supporting the most difficult conditions. The fully enclosed rear chassis resists both torsion forces and shocks. The extra-robust anchorages of the steering cylinders efficiently transmit the steering loads to the chassis. The axle assembly has been optimized for increased structural integrity. The lower articulation axis, frame plate, and bearing size have been increased for greater durability. Robust Structures The push bars are attached across the entire width of the chassis, not just on the side. In the corners of the discharge, the stresses are thus transmitted and absorbed by a larger part of the chassis.
Designed to be efficient
Integrated Steering and Transmission Control System (STIC™) Benefit from maximum responsiveness and control with the STIC system, which combines direction selection, gear selection, and steering into a single lever. A simple movement of the lever to the left or right allows for turning left or right, minimizing driver effort. Ultra-easy gear selection at the touch of a finger. Smoother, faster cycles and less fatigue for operators thanks to integrated controls that require minimal effort. Cat Planetary Powershift Transmission Your success depends on a superior transmission specifically designed for mining applications. Smooth and efficient gear shifting thanks to integrated electronic controls that use the Advanced Productivity Electronic Control Strategy (APECS). Longevity and reliability ensured by heat treatments and metallurgical processes on the gears. Four forward gears and three reverse gears to adapt to all your applications. Cat C18 Engine The long lifespan and exceptional efficiency of your 834K Wheel Loader come from its Cat C18 Engine. Its 6 four-stroke cylinders naturally provide optimal performance. Optimized performance and quick engine response thanks to an electronic control module. Reliable efficiency with perfect control of timing, duration, and injection pressure thanks to the electronically controlled mechanically actuated unit injector system (MEUI™). Increased engine lifespan and improved energy efficiency thanks to lower rated speed. Designed to meet EPA Tier 4 Final and European Stage IV emission standards, equivalent to Tier 3 or Tier 2 standards. Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS) Reduce operating costs by using advanced ICTC and RCS systems to control rim effort. Reduce tire slippage and wear by controlling rim effort from 100% to 25% using the left brake pedal. Once the position corresponding to a 25% reduction in rim effort is reached, the pedal is used for braking again. Decrease the risk of wheel slippage without reducing hydraulic efficiency thanks to RCS. Improve energy efficiency in certain applications with the lock-up torque converter, allowing for direct drive.

Reduced environmental impact
Sustainable Development The concept of sustainable development is at the heart of the features of the 834K. The engine idle shutdown and automatic downshifting at idle functions help save fuel by avoiding unnecessary idling. Our maintenance-free batteries limit waste production. The 834K model is designed to have multiple lives. To help maximize the machine's lifespan, Caterpillar offers a number of options, such as the Reman and Certified Rebuild programs. Within these programs, reused or remanufactured parts allow for 40 to 70% savings, reducing your operating costs. Caterpillar offers upgrade packages to equip older models with new features, maximizing your resources. And if you choose the Cat Certified Rebuild program, these upgrades are included in the refurbishment process.
Specialized Cat Accessories
Cat Blades Cat blades are resistant, durable, and designed with excellent pushing and rolling characteristics. Capacities and widths are defined to ensure maximum productivity. The specific design allows for spreading cover materials and pushing heavier loads. Straight Blade The straight blade (7.9 m3/10.3 yd3) is designed for large-scale pushing of material piles and general earthmoving operations. Universal Blade The universal blade (11.1 m3/14.7 yd3) is designed for moving heavy loads over long distances in mining applications. Semi-Universal Blade The semi-universal blade (10.1 m3/13.3 yd3) combines the characteristics of straight and universal blades. Its capacity has been increased by adding short wings, which only have tips for pushing without sacrificing the characteristics of straight blades. Coal Blade The coal blade (22.2 m3/29 yd3) is designed for precise and productive pushing, ensuring excellent load retention with superior capacity for lighter materials. The wing angles help retain the load during pushing. This blade is available from Cat Work Tool and Services (CWTS). Assemblies Straight, semi-universal, and universal blades consist of the blade, push arms, hydraulic lifting device, tilt and dump cylinders, trunnion mount, stabilizer, and hydraulic line protection.
