Due to the increasing percentage of highly versatile PAT machines on the market and the growing demands for ICT specification equipment, this class of bulldozers has seen a significant increase in demand for the advancement of D65 class HST machines that are consistent with ICT specifications in recent years. The Komatsu TD-7H Bulldozer, which is based on Komatsu’s “quality and dependability,” inherits the DANTOTSU front sight and high operability of traditional HST machines while maintaining the Komatsu quality and reliability. Apart from enhancing environmental protection, economy, safety, practicability, operability, and ease of maintenance, the merchandise power has been significantly increased by adding more modern “ICT.”

Performance and Fuel Economy

To reduce wasteful fuel consumption when the Komatsu TD-7H Bulldozer is left idle for an extended period, it will automatically switch to low idle. The engine’s original speed may be restored by depressing either the work equipment lever or the journey lever. The auto-deceleration time may be adjusted to any value between 3 seconds and 60 seconds, with no restrictions. Increasing the engine’s rated horsepower and blade capacity makes it possible to increase production by 105 percent over the previous D65-18 model. It has been possible to attain the highest output level in its class.

The work efficiency has been increased to 103 percent compared to the current model and the automatic “E” mode previously mentioned. This has been accomplished by using a variable charge pump and the modification of the LS pressure to increase efficiency. To steer, conventional HST machines slow down the inner sidetrack, resulting in a significant reduction in overall travel speed. The Komatsu TD-7H Bulldozer includes an additional feature that allows you to raise the speed of the outer sidetrack to minimize the reduction in travel speed. The maneuverability has been substantially enhanced as a result.

Design, Comfort, and Quality

According to Komatsu, traditionally, GPS machine controls of bulldozers have been focused on the final grade, which has resulted in operators only using the technology roughly 10 percent to 20 percent of the time. Komatsu’s integrated system enables operators to apply automation at any moment, from general site clean-up to trench backfilling, thanks to its modular design. One significant difference between our system and aftermarket alternatives is that our system gathers data at the tracks, while aftermarket systems collect data at the blade. The system provides a real-time image of what is going on around the machine, which is based on data gathered at the track. This allows the system to make calculated judgments depending on the present topography.

Additionally, the technology makes it simpler for businesses dealing with a skilled labor scarcity. With experienced professionals retiring and departing the field, few people are coming forward to fill their positions. The automation for blade control minimizes the amount of labor that new drivers have to perform and lowers the bar for entry into the industry, which she believes is good for everyone. An operator is still required for the machines. ​

While moving across a site, the D51i-24 and D61i-24 dozers employ proactive control to capture terrain data as they go through it. The system makes calculated judgments based on the data, such as whether it should cut and transport material, whether it should spread or fill that material, and if it should continue grading after the material has been cut.

You may now quickly access information on machine locations and service meters on your office computer thanks to the current edition of the “KOMTRAX” system, upgraded to the latest version. Seatbelt non-fastening information is now being sent into the system, a new feature. The system also supports the function of remotely rewriting engine controller software, which is accomplished through communication and Internet technology.
