Machine Service & Support

Caterpillar factory-trained service engineers are available throughout the world to provide our customers with the support necessary to meet their production requirements.


AC IGBT Electrics

With over 30 years of AC experience and over 200 operating AC machines, Bucyrus led the industry in AC electric rope shovels. Caterpillar will carry on this proud tradition.


AccessDirect™

AccessDirect is an electrical interface system that facilitates remote access to a machine’s onboard computer via the Internet.


MIDAS™

Celebrating its tenth anniversary on the market, the MIDAS health monitoring system continues to optimize machine performance by providing, logging and analyzing data on a variety of machine variables.


AccuLoad™

AccuLoad is a data analysis system that provides real-time feedback on dipper loads with industry leading accuracy of ±4% on greater than 90% of all loads. AccuLoad’s load calculation is accomplished without mechanical sensors, eliminating the need for recalibration, a common problem with other load-weighing systems.


Major Structures

Cat major structures are designed for extended performance in harsh mining conditions. Structures are manufactured using cold-weather, impact-resistant, high-strength steel with select welds of full-penetration, profiled and ground type.


Robust Front End Design

The Cat free-floating tubular handle design presents many benefits over traditional rack-and-pinion systems.


Cat® Cab

Caterpillar’s new state-of-the-art operator’s cab is the product of a multi-year collaboration between Caterpillar, mining companies and shovel operators. It has secured one patent and has an additional five patents pending.


HydraCrowd™

HydraCrowd represents the first new crowd technology developed in the past 70 years. A hydraulic cylinder inside the tubular dipper handle maintains all the benefits of the Cat front end while eliminating the need for routine crowd/retract rope replacements.


LatchFree™ Dipper System

The LatchFree Dipper System is Caterpillar’s solution to customers’ number-one cause of downtime­ – the latch assembly. The LatchFree dipper eliminates the latch assembly, replacing it with a strong steel link mounted to the dipper back – away from material flow.


FastFil™ Dipper Design

The unique FastFil dipper provides customers with faster and fuller dipper loads. Its trapezodial shape accommodates the natural configuration of the load, eliminating voids that occur with box-shaped dippers for improved fill factors.


Safety

Safety plays an integral role in everything we do at Caterpillar, from our factory floors to our service centers to our clients’ mine sites.


Training

The relationship between a highly productive mine and well-trained personnel is clear: the ability of your mining equipment to achieve promised production levels is as dependent on the operator’s knowledge and skill as it is on the equipment itself.


Computer Based Training (CBT) Modules

Caterpillar CBT modules provide convenient 24/7 access to training on a variety of topics ranging from safety and operation to mechanical and electrical repairs.


A Commitment to the Mining Industry

As the demand for commodities grows, mining companies need a partner to support them in their efforts. Caterpillar is committed to being that partner.
