854K Wheel Dozer
Overview
854K Wheel Dozer
Engineered for demanding work in large dozing applications, the 854K Wheel Dozer is the largest in the Cat Wheel Dozer line and is an ideal match for large mining operations, power generating utilities, the general contracting industry and wherever mobility, versatility and compaction is needed.
Specifications
Building off the legacy of the 854G, the 854K utilizes a number of key features from the 854G while making enhancements to further improve customer productivity.
Load-Sensing Steering
The 854K features the same load sense steering system as the 854G. Load sense steering maximizes machine performance by directing power through the steering system only when needed, maximizing available power for productive work and improving fuel efficiency.
Next Generation Modular Radiator (NGMR)
The 854K introduces the highest level of cooling performance by using 14 parallel (16 high ambient) modular cores. The NGMR system goes beyond the proven AMOCS technology and increases cooling performance by using brass tubes and copper fins for core construction. Compared to the AMOCS steel tube and steel fin construction, the copper in the NGMR design has a higher heat transfer capability. This enables the 854K to improve cooling performance while minimizing the cooling package area and maximizing rear machine visibility.
Cat Planetary Power Shift Transmission
The 854K heavy-duty planetary power shift transmission is the same field-proven transmission found on the 854G. The 854K transmission utilizes a planetary gear group similar to the one used in the 993K and 994F, which has proven strength and reliability. The electronically controlled power shift transmission features three forward and three reverse speeds, and a maximum rimpull capacity of 75 432 kg (166,300 lb).
Impeller Clutch Torque Converter (ICTC)
ICTC combined with the Rimpull Control System (RCS) allows the operator maximum flexibility in modulating rimpull.
Compensates for wear by providing the ability to recalibrate for optimum left pedal modulation regardless of torque converter wear.
The impeller clutch torque converter uses the left brake pedal to modulate rimpull from 100 to 24 percent of available rimpull for redcued tire slippage.
The RCS selector dial is used to select the desired rimpull setting from four factory presets (Maximum, High, Medium and Low). The reduced rimpull is only active in first gear forward.
RCS will allow the operator to match rimpull to ground conditions.
The torque converter is equipped with a lock-up clutch for direct drive efficiency in second and third gear.
ICTC is standard with lock-up and free wheel stator.
Heavy-Duty Axles
The heavy-duty axles feature standard axle oil coolers, permanently lubed universal joints and strong axle components in both the differentials and final drives for increased performance, servicability and durability.
Axle oil cooling system circulates oil from the brakes and differentials through an oil-to-air cooler that provides increased oil life while extending component performance and durability.
The 854K features planetary reduction in each wheel. Torque is developed at the wheel, putting less stress on the axle shafts. The planetary units can be removed independently from the wheels and brakes.
Conventional differential is standard.
PROVEN ENGINE TECHNOLOGY
The 854K utilizes the Cat® C32 ACERT® engine, certified to meet U.S. EPA Tier 2 and EU Stage II emission. The C32 is a Mechanically actuated Electronically controlled Unit Injection (MEUI) diesel engine. This 597 kW (801 constant net hp), 12 cylinder, 32 liter, turbocharged and aftercooled engine is common with the Cat 777F, 993K, 992K and D11.
The 854K produces the same net power as the 854G but has increased power density with the C32 engine. The increase in power density yields improved engine response and fuel efficiency.
Single Level Blade Controller
The 854K is equipped with a new implement controller. The new implement controller is a fully pilot driven control system from the previous 854G with a cable-driven lift/lower. The new pilot driven implement system is easier to use and minimizes operator fatigue.
The right control pod contains a single level blade control that permits the operator to adjust lift, tilt and pitch with minimal effort. Additionally, with all control centralized in one pod, the operator utilizes less effort while controlling blade movements. Features on the pod include:
1) A momentary switch at the front of the blade control lever changes left-right functionality from tilt to pitch
2) Horn
3) Set/Decelerate - Throttle Lock
4) Resume/Accelerate - Throttle Lock
5) Hydraulic Lockout
6) Dual Tilt
Load Sensing Steering
The 854K's STIC uses a single lever for steering and transmission control. Left hand operation enables the operator to shift or change directions without letting go of the steering control. The STIC reduces operator fatigue by providing an ergonomic location that allows the operator to work with a fluid and effortless motion.
