Incarcatoare frontale de talie mare Cat® 992K

Caterpillar first introduced the 992 in 1968. This large wheel loader has been a global leader ever since, building a reputation as a face loader that's both safe to operate, productive and durable. With the introduction of the K Series, we've enhanced the operator's experience and the safety of those working on and around the machine. With both standard and high lift configurations, this machine will pass match with fleets of 775 and 777 trucks. If your operations revolve around the 992 as a loading tool, you'll find everything that's important to your business in the 992K; safety, productivity, cost control and comfort for your people.

Reliability

Linkage and Frames

We combine 40+ years of design and field experience - as well as new validation technologies - to ensure 992K frames, castings, welds and fabrications are the best in the industry. Our unique box section rear and front frame designs combine plates and castings to manage torsion loads and provide longer lasting alignment for hitch and pin life. Sleeve bearing pins in the linkage are more predictable in their wear and limit daily greasing. For load and carry applications, optional Ride Control further reduces shock loads to the frame while giving the operator a much smoother ride.

Cat C32 Engine

The 992K retains the durability and reliability of the proven Cat C32 diesel with ACERT™ Technology. Like all Cat machines, this engine has been completely integrated into all machine systems resulting in power curves, fuel maps and ratings that are unique to this machine and applications. The solid foundation of this engine starts from our legendary foundries delivering the highest quality engine block. The mechanically actuated, electronically controlled unit injection (MEUI™) ensures that fuel is metered out in optimal quantities for both power and efficiency.

Cat Planetary Powershift Transmission

Nobody builds a better transmission than Caterpillar for earthmoving applications. Everything from gear geometry, heat treatment and metallurgy are Caterpillar design controlled, including the electronics that allow it to integrate with the C32 engine and Impeller Clutch Torque Converter of the 992K. The Cat Planetary Powershift Transmission in the 992K offers three forward and three reverse speeds. The planetary gear group is common with the 993K and 994F large wheel loaders.

Buckets

Selecting the right bucket will dictate the productivity of your loader. The process of selection starts with knowing the density of the material you load. From there, you can select the size and appropriate protection strategies that will suit the rated payload targets of your machine. With a large selection of ground engaging tools, your Cat dealer can help you build a bucket that best suits your application. Custom buckets are an option, however many 992K customers will choose one of the following:

Heavy Duty Rock Bucket

Applications: Face loading tightly compacted pit materials. Moderate abrasion factors and high impact loads are suitable for this bucket.

High Abrasion Rock Bucket

Applications: Face loading iron ore. High abrasion and moderate impact loads are suitable for this bucket. A smooth floor is also desirable. Note: Some applications can be very abrasive. Keep in mind that additional bucket protection can affect the performance of the machine such as higher horsepower loads, higher fuel consumption and affect productivity. With this in mind, it is important that you do not over protect the bucket and replaceable components of the bucket.

Technology Solutions

The 992K 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.

VIMS 3G

Now utilizing the Advisor Display, Vital Information Management System (VIMS 3G) has been improved providing more user friendly interfaces and additional machine data logging. Since 1990 VIMS has been enabling our customers and operators to perform at their best and ensure maximum uptime for our machines using meaningful data.

Operator Profile

Up to 10 separate operator profiles can be stored through Advisor. Screen layouts and machine settings can instantly be recalled providing a quick and consistent setup between operators.

Payload Control System

Payload Control System 3.0 is standard on the 992K providing owners and operators the ability to manage truck payloads and produce accurate records of material movement. This system is designed for on the go weighing. Up to 1,000 trucks can store 25 different materials for comprehensive record accuracy of job site performance.

Automatic Kickout

Operators can easily set the dump height, return to dig/carry or bucket angle from the comfort of the cab. Standard, in-cab programmable kickouts are located in the upper left panel. This feature provides more flexibility and improved productivity when the job requires load and dump target heights.

Cat Product Link

Cat® Product Link enables convenient, remote monitoring of equipment. Get usable information to keep jobs on schedule, maintain machine health and reduce fleet owning and operating costs.

Productivity

Positive Flow Control Hydraulics

The 992K Positive Flow Control (PFC) Hydraulic System is setting a new standard for hydraulic response, performance and efficiency. The implement system is equipped with two electronically controlled, fully variable piston pumps for fast, productive cycles. PFC has concurrent pump and valve control. By optimizing pump control, hydraulic oil flow is proportionate to implement lever stroke. Benefits:

  • Lowered fuel consumption by up to five percent
  • Improved hydraulic response, giving the operator better feel and control of the bucket
  • Improved power efficiency and lower system heat

Impeller Clutch Torque Converter (ICTC)/Rimpull Control System

ICTC maintains hydraulic balance while digging and loading, enabling the operator to finely modulate rimpull by depressing the left pedal, thus reducing the impeller clutch pressure. The further the pedal is depressed, the more the impeller clutch pressure is reduced.

Matched Systems

An efficient loading/hauling system starts with a perfect match. The 992K is matched to the 775 and 777 Cat Trucks providing full truck payloads with minimum loading time. This loading/hauling system will maximize volume of material moved at the lowest operating cost per ton.
