New Electric Drive Cat® 988K XE Wheel Loader Offers Higher Fuel Efficiency And Lower Total Cost Of Ownership

Electric drive loader delivers 25% greater overall efficiency and up to 10% more productivity in load-and-carry applications than the industry leader 988K loader

The new Cat® 988K XE is the first wheel loader offered by Caterpillar with a high-efficiency electric drive system. This new large wheel loader joins the industry leader 988K and the recently launched 986K wheel loaders to provide customers with the most cost-effective loader for each application. Delivering high-production in all loading applications, the 988K XE is recommended for demanding job sites where fuel efficiency makes a difference in the machine’s total cost of operation.

The new loader features switched reluctance (SR) technology and leverages more than 15 years of Cat electric drive experience and more than 4 years of stringent testing in a range of applications for proven reliability in the field. The field proven and tested C18 ACERT™ engine, mechanical dropbox, driveline and axles from the 988K remain in the electric drive machine for consistent, trouble-free operation.

Maximum Efficiency & Productivity

Offering increased truck loading and load-and-carry efficiency, the new 988K XE increases efficiency by 25% overall and by up to 49% in face-loading applications, as compared to the 988K. This reduces costs and helps operations reduce greenhouse gas emissions and carbon footprint. At the same time, Caterpillar production studies report the new loader delivers up to 10% higher productivity in load-and-carry applications.

The new Cat 988K XE loader offers a range of bucket capacities from 6.2-17 yd3 (4.7-13 m3). Rated standard and high lift payload for the loader reaches 12.5 tons (11.3 tonnes) when working with face material and 16 tons (14.5 tonnes) with loose material. Advansys™ Series Ground Engaging Tools (GET) protect bucket components and reduce operating costs, so operations can get the most out of machine performance.

The standard 988K XE wheel loader is performance matched to offer efficient 3-pass loading of the 42.6-ton (38.6-tonne) Cat 770G and 4-pass loading of the 51-ton (46.3-tonne) Cat 772. Its high-lift configuration delivers 5-pass loading of the 61-ton (55.3-tonne) Cat 773G and 6-pass loading of the 70.5-ton (64-tonne) Cat 775G.

Extended Service, Lower Ownership Costs

Cat electric drive technology found in the new 988K XE lowers overall maintenance costs, while increasing engine life expectancy. Offering extended oil change intervals of 2,000 hours, the electric drive wheel loader uses 40% less powertrain oil.

The durable SR drive motor, generator and inverter are built to last through the second engine life with minimum maintenance. Additionally, the efficient electric drive design increases engine life by up to 3,500 hours, extending time between powertrain rebuilds.

To assist with electric drive rebuilds, Caterpillar offers customers world-class service training material, backed by industry-leading customer support from the extensive Cat dealer network. Remanufactured drive motors, generators and inverters will also be available to reduce rebuild cost.

Similar Operation, Greater Productivity

Slight changes inside the cab of the new 988K XE provide operators with the familiar functions and feel of the 988K. At the same time, operators will experience improved handling smoothness and ease of operation. The new loader offers a single speed range, so the machine efficiently operates without the need for gear shifting. New virtual gears help to control machine ground speed and deliver smooth direction shifts.

The standard Cat Product Link™ offers remote data monitoring through VisionLink®, so key personnel can stay informed of critical machine operating data.  Fuel usage, payload summaries, scheduled service reminders, fault code alerts and various productivity reports are available to help improve machine management.  Additionally, the onboard Vital Information Management System (VIMS) provides the operator with operating data such as real-time fuel consumption and fuel efficiency via an interactive touch screen display.

The new Cat 988K XE loader is equipped with a host of technology solutions to increase operating efficiency and machine uptime. Cat Production Measurement (CPM) brings payload weighing to the cab, so operators can work more productively and deliver accurate loads with confidence. CPM offers advanced weighing modes, which assist with payload accuracy and increase loading cycle speed.

Optional Tire Pressure Monitoring System (TPMS) is a fully integrated Cat feature, which enables operators to monitor tire inflation. Available through the VIMS display, the operator can quickly view each tire’s pressure and take action when needed to reduce wear and increase service life.

As customers have come to expect from the 988K, operators safely access via left- or right-hand stairs built at a reduced 45-degree angle and maintain three points of contact at all times. The STIC steer armrest easily folds up, allowing the operator to quickly enter the cab. Isolation cab mounts and an air-suspension seat reduce vibration transmitted to the operator for increased comfort, while the enclosed pressurized structure reduces operator sound levels. The automatic, in-cab temperature control system maintains operator comfort even in extreme temperatures.

MICHELIN Introduces New Rigid Dump Truck Tire

XTRA LOAD Tire Range Provides Productivity Advantages for 40- to 80-ton Payload Trucks

Michelin Earthmover today announced the next generation of rigid dump truck (RDT) tires with the introduction of MICHELIN® X®TRA LOAD GRIP and the MICHELIN® X®TRA LOAD PROTECT. The first-ever “3-star” 24.00R35 tire size on the market1, the new MICHELIN XTRA LOAD range will allow users to increase load capacity or accommodate faster speeds to maximize productivity.

“It is a common worldwide practice to add side boards and lift gates to rigid dump trucks in order to increase payload capacity for optimal profitability. This demand puts incredible stress on the tires,” said Jamey Fish, director of earthmover marketing for Michelin North America Inc. “This new, robust Michelin tire range provides a solution so that the maximum amount of material can be loaded into these trucks while still delivering traction, damage resistance and increased tire life.”

The new MICHELIN XTRA LOAD tire is available for two surface applications experienced by RDTs:

MICHELIN XTRA LOAD GRIP for soft, loose, muddy ground conditions — experienced in mining and quarrying operations on slopes and inclines, where the priority is high grip and traction. Due to a reinforced casing, the tire has a 16 percent higher payload2, or an increase of nine tons in load capacity per machine — a huge increase in productivity when multiplied by the number of cycles made daily. And with a tread comprising 30 percent more lug edges3, increased grip improves braking, cornering and accelerating. The tire has the ability to drive 21 miles per hour due to the cooler internal running temperatures4. The tire also provides 8 percent more wear resistance5, with more rubber in the contact patch and improved damage resistance with corrosion-isolating steel cables. This tire replaces the Michelin XDT® and X® Traction offers.

MICHELIN XTRA LOAD PROTECT for hard, sharp, abrasive conditions on flat, dry surfaces — where the priority is protection and damage resistance, conditions that are present in areas such as quarries and construction sites. This application is for customers who want to carry more load and increase the distances they carry every hour. The new highly protective and damage-resistant tread pattern contributes to a better load distribution across the contact patch. This tire has interlocking blocks and improved heat dissipation that reduces the temperature in the tread area by up to 17 degrees F. This tire replaces the Michelin X®QUARRY S and X®HAUL tires offers.

Productivity — as measured by TMPH — is a function of load and distance covered in an hour. For the new XTRA LOAD GRIP, the TMPH is increased by at least 20.3 percent in the A4 compound and 13.5 percent for the B compound, when compared against previous Michelin ranges6. For the new XTRA LOAD PROTECT, the TMPH is increased by at least 14 percent in the A4 compound and 42 percent for the B compound, when compared against previous Michelin ranges. This extended load and speed capability will allow users to optimize machine cycles and increase productivity. Greater volume of tread rubber in contact with the ground contributes to better load distribution, improved wear resistance and an increase in tire life.

With the two tread compounds (A4 and B), dealers will experience easier stock management. The four new Michelin offers will replace five existing offers as outlined below:

XTRA LOAD GRIP A4*** replaces XDTA4**

XTRA LOAD PROTECT A4*** replaces X-QUARRY S**

XTRA LOAD PROTECT B*** replaces X-HAUL**

1) Previously most 24.00R35 tires carried a ** rating; the X®TRA LOAD is the first carrying a *** rating. Star rating is the industry indicator of load capacity for a given dimension governed by the Tire and Rim Association. Compared to the same size in BRIDGESTONE® VMTP and VRLS – Source BRIDGESTONE® OTR Databook 2016 and MICHELIN® XDT™, MICHELIN® X® TRACTION™ SC – Source Michelin Databook 2017.

2) 30% more lug edges in contact with the ground. Based on customer feedback done on: 140 tires (field tests) in 10 countries at 23 customers during 2016 and 2017.

3) Star rating is the industry indicator of load capacity for a given dimension – Tire and Rim Association.
