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%>
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
Higher performance is claimed for Komatsu’s Dash 7 version of its well-proven HD785 rigid dump truck, which offers a heaped capacity of 60m3. The 91tonne capacity HD785-7 is matched to Komatsu’s PC1250 and PC2000 excavators, and WA800 and WA900 wheel loaders. The new version of the truck is said to be more powerful than the previous generation machine, with drive from a Komatsu SAA12V140E-3 diesel delivering 1,178kW.
Komatsu’s new PC138US-10 short-tailswing hydraulic excavator has an operating weight between 13,400 and 14,467kg, comes with a 69.7kW Stage 3B/Tier 4I-compliant engine and has improved hydraulic efficiency and operator comfort. The PC138US-10 is supported by the Komatsu CARE complimentary three-year/2,000hr maintenance programme. The company said lift capacity and stability of the compact machine are comparable to a conventional excavator, while the contoured cab swings within the same radius as the count
