CAT OFFERS COMMAND REMOTE OPERATION FOR MEDIUM DOZERS
To boost jobsite safety in hazardous dozing conditions, Caterpillar announced the expansion of Command remote machine operation to Cat D5, D6, and D7 Dozers.
Command for Dozing removes operators from the cab and offers remote operating from a safe distance in applications such as overburden/reclamation work, ripping overburden or leach pads, slurry pond dozing, and operation around hazardous materials or unstable surfaces.
Next generation dozers are shipped from the factory remote ready, making field installation fast with only a few additional parts required. With Command fully integrated with the machine’s electronic and hydraulic systems, remote operation delivers quick response, smooth control and virtually no latency.
Companies have the option of equipping dozers with line-of-sight (LOS) or non-line-
of-sight (NLOS) operation, and a groundlevel switch quickly toggles between manual and remote dozer operation. To help improve jobsite productivity, Command allows production to restart immediately following disruptive processes, such as blasting in quarry applications.
Beyond improving safe operation and increasing productivity, Command for Dozing offers a potential solution to worker shortages and added training opportunities for newer operators. By allowing the operator to work outside the machine, Command opens opportunities to those with physical limitations which prevent them from climbing into the equipment. It can attract a new generation of worker while increasing the longevity of experienced operators.
Two Options, Precise Control
Portable and lightweight, the command console (LOS) allows workers to work outside of the cab while remaining on site and in direct visual contact with the dozer. With its range reaching 437 yds., the console positions the user for optimum visibility.
Requiring no on-site communications infrastructure, it is ideal for short-term and emergency remote operation. An ergonomic console layout features intuitive controls with ISO symbols that provides access to all dozer functions, while an LED display offers clear readout of machine status.
an electronic access card, the console can be configured to control another machine equipped with Command by simply changing out an RFID chip. Its lithium-ion battery provides a quick charge and long run times in varying ambient temperatures.
Built-in safety features stop all dozer movements if the remote shutdown switch is pressed, wireless communication is lost, or the console is tilted more than 45 degrees.
The command station provides non-lineof-site operation from the comfort of an airconditioned office on-site or many miles away, as distance is limited only by the capabilities of the wireless network. By eliminating the fatigue-inducing vibration of machine movements in the cab, operators can work with less fatigue.
The configurable station features a similar feel to the cab with familiar controls, complete with pedals, joysticks, adjustable seat, switches and storage. Multiple screen displays offer visuals from the left and right cutting edges, blade top-center and rearview that includes the ripper.
Beyond supporting assist technologies offered by the console (LOS), the command station (NLOS) offers compatibility with blade load monitor, slope assist and Grade with 3D with the same response time as in the cab. Users can easily switch to operating a different command-equipped machine — dozer, wheel loader or excavator — from the same or different sites with virtually no downtime for shift changes or for travel to the job site.
The command station provides non-line-of-site operation from the comfort of an air-conditioned office on-site or many miles away, as distance is limited only by the capabilities of the wireless network.
Furthering operation simplicity, the console (LOS) system supports multiple assist technologies the operator would have from inside the cab, including traction control, AutoCarry and stable blade.

Doosan Plans to Produce Larger Model DD130 in 2023
DOOSAN from page 60 machine functions are not used for a predetermined period, the auto idle feature idles the dozer engine to reduce fuel consumption. When the operator moves the controls, the dozer automatically returns to the previous throttle setting.
The auto shutdown feature saves fuel and helps lower warranty hours. When the feature is enabled, the engine shuts down after it has been idling for a specified period. Default shutdown occurs after five minutes of idling but can be set for longer periods by the operator using the Smart Touch display. Versatility
Doosan dozers come standard with piping for an optional ripper attachment. The ripper attachment features parallel linkage that helps maintain a constant angle to the ground regardless of the height. The attachment can quickly break up hard, rugged materials prior to grading, and it can be used to install erosion control. Also available as an attachment is a towing draw bar, allowing operators to use the Doosan dozer to tow other equipment on a job site. Durability
One of the dozer’s key features is its undercarriage design. Doosan developed its dozer undercarriage system to help lower the total cost of operation. The design includes both single- and dual-flange rollers for improved durability and long life.
Customers can choose from several track guards to enhance uptime protection. They include general-purpose and full guard options to fit the jobsite conditions. In addition, track shoe options are available to help distribute the load to the ground. Thinner tracks are used for rugged, rocky environments. A low-ground pressure option is available for sandy soil conditions. Serviceability
An in-line precleaner helps improve filter life and is integrated with the air cleaner. It’s also more compact to fit in the smaller engine compartment. Self-cleaning and maintenance-free, the intake system can expel a variety of debris, including mud, snow, rain, leaves, sawdust and chaff.
Doosan designed its dozer undercarriage for convenience and cost-effective maintenance. Areas of the undercarriage that naturally experience greater wear and tear are easy to access. For example, a removable side panel provides access to an area to add grease to the undercarriage’s tension system. Customers can order replacement parts through their local Doosan dealer.
To help minimize fuel-related issues, Doosan offers a filter-type high-performance water separator, which captures moisture in the fuel and reduces impurities. Standard pre-filters and dual main filters achieve a high degree of purity that minimize fuel system failures. The fuel filter water separator and the main fuel filter can easily be reached by lifting a panel on the front of the dozer.
Common, everyday maintenance items can be accessed from ground level, including the following components: • Electronic main control valve • Diesel fill • Diesel exhaust fluid fill • Hydraulic oil fill • Fuel filter • Engine oil filter • Air cleaner • Battery • Windshield wash tank
When necessary, owners can tilt the dozer cabin to reach critical components. Even with the cab tilted, the dozer can be started while the machine is being diagnosed or repaired.
Doosan DD100 dozers are designed with a unique hydraulically controlled cooling system and come standard with a reversible fan. Operators can set the fan to automatically reverse at a predetermined time interval. The cooling system is in the rear of the machine instead of the front. This contributes to better visibility to the blade from the operator’s point of view.
