834K created for several lives. To help extend the life of the machine, Caterpillar offers a range of sustainable options, such as our Reman and Certified Rebuild programs. In these programs, reusable or remanufactured components can provide cost savings of 40 to 70 percent, which reduces operating costs.
Caterpillar offers retrofit packages that allow you to use new features on older machines and maximize your resources. And when you complete the Cat Certified Rebuild program, these upgrade kits are part of the recovery process.
Cat blades
Cat blades are resilient, durable and have excellent metering and rolling characteristics.
Capacity and width are set to increase performance.
The design of spreading allows scattering of the coating material, as well as the dosing of heavier loads.
DIRECT BLADE
The straight blade (7.9 m3 / 10.3 yd3) is intended for dispensing products in warehouse materials and general earthworks.
UNIVERSAL BLADE
Universal knife (11.1 m3 / 14.7 yd3) is designed to move large loads over long distances in mining.
SEMI-UNIVERSAL BLADE
The characteristics of straight and universal knives are combined into a semi-universal knife (10.1 m3 / 13.3 yd3). It provides improved performance by adding short wings that only include the end tips of the bulldozer, without sacrificing the expansion characteristics of the straight blades.
COAL BLADE
The coal dump (22.2 m3 / 29 yard 3) is designed for accurate and productive dosing, helping to maintain load control with an increased capacity for lighter materials. The corners of the wings help keep the load during sleep. This blade is available in Cat Work Tool and Services (CWTS).
ASSEMBLIES
Straight, semi-universal and universal blades consist of blades, pushing levers, hydraulic lifting, tip and tilt cylinders, trunnion, stabilizer and hydraulic barriers.
OTHER AVAILABLE OPTIONS
Contact your Cat dealer for blade options such as coal and wood scoop from CWTS and Custom Products.
The 834K has several features to achieve greater fuel efficiency:
Hydraulics with positive flow control - provides only the hydraulic flow required for attachments and steering systems to increase fuel efficiency and increase traction.
ACERT Engine - Advanced engine management maximizes power and efficiency.
Shutting down the engine at idle - automatic shutdown of the engine and electrical system saves fuel.
Blocking torque converter - transmits more power to the ground and optimizes fuel efficiency in all applications.
Advanced Electronic Performance Management Strategy (APECS) - All new APECS gearbox controls provide greater momentum on slopes and fuel savings, transferring this momentum through shift points. The configuration of the machine, the operator`s technique and the location of the working platform can affect fuel consumption.
Machine Configuration — Choose the right tool and type of tire for your application. Provide proper inflation pressure.
Idling - engage the parking brake to activate the engine idling control system.
WE CAN HELP YOU TO MAKE SURE YOUR 834KB HAS THE FEATURES OF THE DESIGN TO REDUCE YOUR TIME.
Safe and convenient service with terrestrial or platform access and grouped service points.
Swing doors on both sides of the engine compartment provide easy access to important daily maintenance checks.
