Komatsu is widening its line of intelligent dozers
2300 Komatsu is broadening its range of intelligent dozers with an additional three models. The 37PXi, 39PXi and 51PXi machines all feature similar intelligent machine control (iMC) technology to the existing D61PXi-23, which was introduced in mid-2013. The D61PXi-23 features a 125.3kW diesel while the 37PXi, 39PXi and 51PXi are in the power rating classes of 66kW, 78kW and 97kW respectively. These dozers are all capable of handling rough dozing along with finish grading while operating in automatic mode, with fully automatic blade control. For rough dozing work, the automatic blade control monitors blade load and adjusts blade elevation to minimise track slip for high-efficiency operation. As work progresses closer to the target finish grade, the automatic blade control adjusts accordingly to provide finish grade performance with high-level precision. Improvement in combination rough dozing efficiency is up to 13% higher compared to add-on machine control systems for tested models. This is because the sensors are integral to the machine so readings are more accurate. With Komatsu’s iMC crawler dozers, typical add-on machine control system components mounted on the blade have been replaced with factory installed cab top GNSS (Global Navigation Satellite System) antenna, enhanced inertial measurement unit (IMU+), and stroke sensing hydraulic cylinders. These components along with the machine control monitor and controllers mounted inside of the cab are installed at the Komatsu manufacturing facility during machine assembly. %$Linker: 2Asset<?xml version="1.0" encoding="utf-16"?><dictionary />2489770oLinkExternalwww.komatsu.comKomatsu Websitefalse/EasySiteWeb/GatewayLink.aspx?alId=48977falsefalse%>
The D65-17 dozer gets an 8.9litre stage IIIB certified Komatsu engine, and with 152kW at 1,950rpm, brings a net power increase while reducing fuel consumption by over 5% when compared to the model it replaces.

Caterpillar is offering new machine control packages for use with dozers
Caterpillar is widening its range of solutions for dozers with the introduction of the GRADE with 3D system for its D3K2, D4K2 and D5K2 models.
This package is an automated grade control system using GNSS technology to position the machine's blade, without operator input, from first rough cut to finish grade. In addition, GRADE with 3D incorporates the Cat AccuGrade Ready Option. This system allows the use of universal-total-stati
An array of performance improvements ensure that Komatsu’s 5.3tonne class PC55MR-3 midi excavator offers increased performance over earlier generation machines. Weights range from 5.28- 5.35tonnes depending on specification and the PC55MR-3 features a tight tail design that allows the machine to work in restricted spaces. Power comes from a Komatsu 4D88E-6 diesel that meets the necessary emission standards. High operator comfort is claimed due to ergonomic controls and the machine also offers good visibilit
