Cat extends semi-autonomous operating tools to small loaders series

Command for Loading has been added to Cat 926M, 930M and 938M model options. Removing the operator from the wheel loader, it provides semi-autonomous remote control to increase safety and is available in line-of-sight or non-line-of-sight operating configurations. By allowing users to comfortably control the machine from a safe location, Command for Loading maintains high machine productivity in challenging operating environments.

Command for Loading configured to the Cat 930M shown here, plus 926M and 938M models, will be available later this year.

The system includes rear and side cameras, electric over hydraulic steering system and machine-mounted activation lever for ground-level access. Cameras, indicator lights, microphone, wireless receiver and antenna are installed on the cabin roof. Since Command controls are integrated with machine electronics, users will experience the same response as they would operating inside the cab, allowing for productivity to be maintained from a distance.

Line-of-sight Command for Loading operation comes complete with a lightweight, compact control console supported by a comfortable shoulder harness. Basic machine controls like startup/shutdown, bucket rack/dump, and lift/lower are easily accessed through the ergonomic Command console control layout. Machine commands sent from the remote console are direct to the engine and implement electronics via a detected radio—reducing response delay. To ensure users maintain machine control at all times, integrated Caterpillar electronics activate safety features to stop all wheel loader movements if A-stop or Remote Shutdown Switch is pressed; wireless communication is lost; a severe fault is detected; or, the Command console is tilted more than 45 degrees from normal operating position. Line-of-sight control with the Command console extends up to 437 yards to allow for convenient remote operation.

The non-line-of-sight Command for Loading solution includes a modular, customized station that positions users in a familiar and comfortable seated position simulating traditional machine control. One user can connect multiple machines from a single station, but only control one machine at a time. Station components include machine joystick and foot pedal controls for all Command technology-capable machines. A touchscreen mount is incorporated in the station design for machine control, while universal screen mounts are included for wheel loader camera displays. An emergency A-Stop or Remote Shutdown Switch button is located on the Command station to quickly halt all machine movements. At the jobsite, an optional remote All-Stop control is available for crews working around non-line-of-sight Command loaders.
