The next-generation Cat D1, D2 and D3 small dozers now feature an enhanced suite of easy-to-use operator-assist technologies, including stable blade lift and tilt, load monitor the blade, slow-slip traction control and AutoCarry.
D1-D3 bulldozers also offer a Cat Command for dozing remote control (RC) ready option, along with additional mounting features and wiring harness routing paths to streamline the installation of control systems. third-party leveling. Simplifying operator training and transition from small to medium machines, Cat small dozers now feature the same Cat Command system found on Cat medium dozer models.
Cat operator assistance features build on existing technologies: Traction Control, Stable Blade and Grade Assist. Supplied as Cat Attachment Ready (ARO) with Assist and Grade 3D with Assist packages, the new Stable Blade Lift and Tilt improves performance over the Stable Blade. The feature combines accelerometers with an advanced control algorithm to automatically perform minor blade lift, lower, and left/right tilt commands to compensate for machine motion.
New Blade Load Monitor, Low-Slip Traction Control and AutoCarry are built into Cat Grade 3D with Assist. Blade Load Monitor provides real-time feedback of current machine load versus target machine load, helping new and experienced operators make full use of machine capacity. Automatically compensating for ground conditions, this technology actively monitors both machine load and track slippage and provides feedback to the operator on current load versus optimum pushing capability.
With two modes of operation (normal and low-slip), low-slip traction control automatically prevents excessive track slippage to increase machine efficiency while reducing operator load, says Cat. The default normal mode setting automatically limits unproductive chain slippage when pushing heavy blade loads. Operator-selected low-slip operating technology dramatically limits track slippage in applications sensitive to minor track slippage, such as material spilling over the top of a pavement.
Working in unison with other operator assist features, AutoCarry automatically raises and lowers the dozer blade to maximize pushing capacity and prevent excessive track slippage when pushing heavy loads. When activated by the operator, AutoCarry stays in standby mode until the blade is fully charged, then automatically engages without the need to use Slope Assist or Grade 3D to activate the technology.
Cat D1-D3 bulldozers now offer an RC ready option that simplifies dealer installation of Cat Command for the bulldozer. Cat Command allows dozers to be operated remotely from a safe distance, eliminating safety risks associated with potentially hazardous applications. By integrating with the machine’s electronics, it allows users to retain the same control as if operating inside the cab.
To maintain access to advanced machine functionality, Cat Command for Grading is available in two configurations: line-of-sight and non-line-of-sight control. The ergonomic control layout of the lightweight, over-the-shoulder control console provides line-of-sight machine control from up to 1,312 feet away, allowing for convenient remote operation. To ensure the operator maintains control of the dozer at all times, built-in Cat electronics activate multiple safety devices to stop all machine movement under the following conditions: the total stop switch is pressed; control stop is activated; wireless communication is lost; a serious fault is detected; or the control console is tilted more than 45 degrees from the operator’s normal position.
The custom off-site operator station positions the user in a familiar and comfortable seated position, simulating traditional machine control. A single station allows users to control multiple Cat machines one at a time, and is compatible with other Command offerings for Cat equipment. Station components include machine joystick and foot pedal controls as well as touch screen support for machine control. Universal screen mounts are included for dozer camera screens.
Cat operator assistance features are available on D1-D3 dozers. Dealer Command installation kits for leveling are now also available, and machines in the field can be fitted with the technology.
