Wheel loaders operating in mining and quarry & aggregates applications face a number of potentially dangerous areas, such as high walls, stockpiles, steep slopes, unstable surfaces and areas where there are hazardous materials or the possibility of falling debris. Cat® Command for loading on the 988K Wheel Loader is a line-of-sight remote control system which removes operators from potentially hazardous situations. Command for loading on the 988K uses wireless technology and on-board electronic systems to allow the machines to be controlled without an operator in the cab.
Reduces operator safety risks such as high wall collapse, machine rollover or fall.
Decreases potential for injury from slips, trips and falls when climbing on and off machine.
Includes multiple, redundant safety features to stop all motion of machine if a stop switch is pressed, wireless communications are lost, a severe fault is detected or the console is tilted more than 60 degrees from normal operating position.
Prevents accidental activation with console that is unique to each machine system.
Prevents coasting in neutral thanks to auto hold feature.
Simple installation procedures provide step-by-step instructions to quickly and efficiently implement the system with minimal machine downtime.
By utilizing the machine's existing hydraulic valves and electronic harnessing, reliability is greatly increased over non-integrated systems.
Quick system response and fine modulation of controls are enabled through comprehensive machine integration of the electronic and hydraulic systems.
Commands from the operator console are sent directly to the engine and implement electronics via a dedicated radio, reducing delays.
The system allows complete control with access to advanced features offered on Cat machines such as Autodig, an optional feature that increases productivity.
Rugged and Functional Design of the Operator Console
Fully functional operator console contains basic machine functions such as start-up/shutdown, gear selection, rack/dump and lift/lower are easily accessed through the ergonomic layout of console controls.
Critical machine and system status information is also delivered through the operator console.
LED indicator lights and display show the oeprator the gear selection, temperatures, oeprationsal mode, faults, systems status, and low battery warning.
Integration of Caterpillar electronics enables the activation of several safety features to ensure the operator is in control of the machine at all times.
Operator console allows for line-of-sight control up to 400 meteres (437 yards).
The 3.85 kg (8.5 lb) operator console has been designed to enable the operator to work an entire shift comfortably.
Rugged and Functional Design of On-board Components
Roof-mounted electronics enclosures house the antenna, indicator lights, and wireless receiver.
Ground level service center contains a remote/manual switch and an engine shutdown switch as well as an optional ladder and delayed lighting switches.
A wireless transmitter/receiver is used to communicate between the operator console and the remote contrl electronics located in the machine.
