Featuring all new Advanced Productivity Electronic Control Shifting (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
Your operators can work more efficiently and stay comfortable with our customer-inspired cab features.
The 834K electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator, maximizing the productivity of both.
Cat Product link allows remote monitoring of equipment to improve overall fleet management effectiveness. Events and diagnostic codes, as well as hours, fuel, idle time and other information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.
Cat MineStar System is the industry's broadest suite of integrated mine operations and mobile equipment management technologies, configurable to suit your operation's needs. Its capability sets - Fleet, Terrain, Detect, Health and Command - contain a range of technologies that let you manage everything from fleet assignment and condition monitoring to remote and autonomous control. The 834K can take advantage of many of these advanced technologies, some of which are standard out of the factory.
Fleet provides comprehensive, real-time machine tracking, assignment and productivity management, giving you a comprehensive overview of all operations from anywhere in the world.
Terrain with your 834K enables high-precision management of loading operations through the use of guidance technology. It increases 834K productivity and provides you real-time feedback for improved efficiency.
Detect helps increase operator awareness, enhancing safety at your operation. It includes a range of capabilities designed to assist the operator with areas of limited visibility around fixed and mobile equipment.
Health delivers critical event-based machine condition and operating data for your entire fleet. It includes comprehensive equipment health and asset monitoring capabilities, with a wide range of diagnostic, analytic and reporting tools.
We are constantly introducing features on our machines in an effort to enhance safety for the operator.
The straight blade (7.9 m3/10.3 yd3) is designed for production dozing in stockpile material and general earthmoving.
The universal blade (11.1 m3/14.7 yd3) is designed to move large loads over long distances in mining applications.
The characteristics of the straight and universal blades are combined into the semi-universal blade (10.1 m3/13.3 yd3). It provides increased capacity with the addition of short wings which include only the dozer end bits without sacrificing spreading characteristics of straight blades.
The coal blade (22.2 m3/29 yd3) is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials. Wing angles help retain the load while dozing. This blade is available from Cat Work Tool and Services (CWTS).
The straight, semi-universal and universal blades consists of the blade, push arms, hydraulic lift, tip and tilt cylinders, trunnion mounting, stabilizer and hydraulic line guards.
See your Cat dealer for blade options such as coal and wood scoop from CWTS and Custom Products.
