Caterpiallr  has just announced 'Command for dozing', an integrated remote control system for Cat D10T and D11T tractors.
Caterpillar goes
high-tec for remote dozing capability

Forget playing with remote controlled scale models or interactive computer games. Now it is possible in full scale reality - and all in the name of 'safety'.

Caterpillar has constantly been at the forefront of recognizing advanced in technology and rapidly evaluating it’s value to customers and introducing it, as appropriate, to equipment in the extensive product range.

The company has just announced ‘Command for dozing’, an integrated remote control system for Cat D10T and D11T tractors. The new system enables remote, line-of-sight operation using a portable console, which allows the equipment operator to stay out of hazardous areas, such as under highwalls, near slides or pushing to underground feeders in stockpiles. The system enables mining and bulk materials handling operations to work safely, productively and economically in a broad range of applications.

It differs from aftermarket add-on systems inn that it is fully integrated within the Caterpillar designed components, systems and electronic control modules (ECM) used on the D10T and D11T. Integration reduces complexity and cost and enables the system to deliver higher performance, better reliability, longer life and enhanced safety. The system also allows using Autocarry and Auto Blade Assist for high productivity.

‘Command for Dozing’ is the first globally available commercial product in the Command capability set of Cat MineStar System, the comprehensive and fully integrated mine and mobile equipment management system.

Command for dozing has the ability to use avoidance zones set up in Terrain, another Cat MineStar System capability set. A tractor equipped with Terrain uses GNSS to create three-dimensional electronic fences around fixed objects and hazardous work zones. The boundaries are then communicated to Command for dozing to warn the operator and, if necessary, to stop the machine before it enters an avoidance zone.

The operator console weighs approximately 8.5 lbs (3.85 kg) and is fitted with a shoulder harness for convenience and portability. It is available as a 900 MHz unit with an operating range of up to 2,625 ft (800 m) and as a 2.4 GHz unit with an operating range of up to 1,600 feet (500 m) depending on environmental conditions. The system meets ISO 15817 and AS/NZS 4240 standards. Safety, efficiency and portability

The system features a console from which the operator can perform virtually all machine functions—including engine startup, acceleration, deceleration and shutdown; shifting, steering, directional control and braking; blade and ripper control; and auxiliary functions such as lights and horn. Critical information normally displayed in the cab via gauges and other displays is replicated on the operator console.

The system meets ISO 15817 and AS/NZS 4240 standards.

To enhance safety, the Cat system will bring a remotely controlled large track-type tractor to a stop when any emergency shutdown switch is activated (such switches are located in the cab, on the operator console, in the ground-level service centre and on an optional redundant emergency shutdown transceiver); operator console is tipped; off-board transceiver loses power; radio communications are lost; communications to on-board transceiver or any ECM are lost or alarms from any ECM are activated

Other standard safety features include an AutoRetarder function for engine overspeed protection and an AutoBrake function that engages when the machine is in neutral.

Caterpillar will introduce a more enhanced generation of ‘Command for dozing’ in late 2011. This version of the remote control system will deliver audio and video feeds to the operator, who will work from a cab-like environment in a remote location.
