Cat MineStar™ System
Work more productively.
Cat MineStar™ System is the industry’s broadest suite of integrated mine operations and mobile equipment management technologies, configurable to suite your operation’s needs. Its capability sets – Fleet, Terrain, Detect, Health and Command – contain a range of technologies that let you manage everything from fleet assignment and condition monitoring to remote and autonomous control. The 994H can take advantage of many of these advanced technologies, some of which are standard out of the factory.
Fleet
Fleet provides comprehensive, real-time machine tracking, assignment and productivity management, giving you a comprehensive overview of all operations from anywhere in the world.
Terrain for Loading
Terrain with your 994H enables high-precision management of loading operations through the use of guidance technology. It increases 994H’s productivity and provides you real-time feedback for improved efficiency.
Detect
Detect helps increase operator awareness, enhancing safety at your operation. It includes a range of capabilities designed to assist the operator with areas of limited visibility around fixed and mobile equipment.
Health
Health delivers critical event-based machine condition and operating data for your entire fleet. It includes comprehensive equipment health and asset monitoring capabilities, with a wide range of diagnostic, analytic and reporting tools.
13
Safety
Making your safety our priority.
Powered Access System
The Cat powered access system allows easier access to the primary stairs by improving ingress and egress to and from the rear platform. • All operators have adequate space when using the wide stairway. • Operators maintain three-point contact when using full handrails on each side. • Occupants can quickly exit with a conveniently located emergency release valve if the loader becomes inoperable.
14
We are constantly improving our products in an effort to provide a safe work environment for the operator and those who work on your job site.
Machine Access
• Wider stairs with reduced stair angles increase safety for operators getting on and off the 994H. • Walkways with non-skid surfaces and integrated lock out/tag out points are designed into the service areas. • Windshield cleaning platforms provide safe and convenient access for the operator. • Maintain three points of contact at all times through ground level or platform accessible service areas. • Emergency egress access.
Visibility
• Standard pull-down window shade and optional heated mirrors ensure extended visibility for safe operation. • Cat Detect with Object Detection System (rearview camera and radar) or Vision (rearview camera) option increases operator awareness around the machine. • Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
