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%>
Komatsu Europe is widening the range of intelligent bulldozers it offers. This new addition to the line-up brings the range of intelligent dozers from Komatsu to five models in all. The new D85EXi/PXi-18 dozer is said to offer all the benefits of the existing D85-18 dozer, with improved efficiency and reduced running costs for customers.
Komatsu used INTERMAT to take the wraps off two new Dash 7 wheeled loaders, badged WA380-7 and WA500-7. With engine emissions being the main driver, the smaller 18-tonne WA380-7 packs 142kW from its EU Stage IIIb engine to deliver improved efficiency and lower fuel consumption. The machine also gets torque converter lock-up with the function operating in 2nd, 3rd and 4th gears, and gives the loader a 40 km/h forward speed.
Improvements to Komatsu’s PC700LC have resulted in the Dash 8 version. Operator comfort gets the biggest change, with an all-new cab that gets a fixed, laminated front windscreen for increased operator protection, a heated high-back air-suspension seat, and a standard rear-view camera. Also new, for maximum efficiency said the company, is a widescreen LCD colour monitor panel that integrates Komtrax ‘step 3’ functionality with fuel consumption monitoring. The 323kW PC700LC-8 has an operating weight from 65-
