KOMATSU D58 CRAWLER DOZERS:THE MOST EFFICIENT DOZERS IN THEIR CLASS When you think Komatsu D58, think efficiency. Efficient because every D58 is equipped with Komatsu s TORQFLOW transmission. TORQFLOW provides lighttouch, smooth gearshifts that substantially reduce operator fatigue and increase productivity. Efficient because the D58 s 130HP diesel engine is specifically designed to handle the toughest operating conditions while reducing frictional loss and minimizing fuel consumption. Efficient because every D58 dozer features Komatsu components built to the most exacting quality assurance standards in the world components built for reliability and durability. That means less downtime and easier maintenance. The D58 crawler dozer economical, easy to operate, reliable, durable, easy to maintain, equal to the most difficult operating conditions efficient.
D58E-1, D58P-1 CRAWLER DOZER 2 1 3 LH F RH LH N 2 1 3 R RH LIGHT-TOUCH CONTROL SYSTEMS INCREASE OPERATOR COMFORT AND PRODUCTIVITY The D58 is equipped with Komatsu s TORQFLOW transmission, assuring smooth gear shifts and powerful traction. It consists of a 3-element, singlestage, single-phase torque converter and a hydraulicallyactuated planetary-gear transmission with multiple-disc clutch packs. This unique system assures light-touch, ultra-smooth gear-shifting through the 3 forward and 3 reverse gears to decrease operating fatigue. Responsive Operation A single lever joystick on the left controls all speed and directional changes including: 1st to 3rd Forward and reverse Right and left steering A single T type joystick on the right controls all blade functions including: Lifting and lowering Angling Tilting This left and right joystick system offers unparalleled control for shorter cycle times.
Float Lower LH Angle RH Angle LH Tilt Hold RH Tilt Raise DESIGNED FOR MAXIMUM DURABILITY, RELIABILITY AND MAINTAINABILITY Every Komatsu crawler is manufactured with Komatsu-built components. Since each component is produced under the world s strictest quality control, reliability and durability are assured. Maintainability is also a factor contributing to machine efficiency and economy, and the D58 offers you more. Segmented Sprockets Sprockets are segmented into several pieces and installed on the sprocket hub. Worn segments can be replaced without removing the track frame. This results in quick and easy in-field replacement and reduced downtime. Lubricated Track Links (optional) Since the clearance between the link pin and bushing is lubricated, wear and pitch elongation are minimized for extended service life. With lubricated track, power loss due to friction of pin and bushing is reduced, increasing operating comfort and performance. Split master links are also provided to facilitate easy track assembly and disassembly. Wet Type Steering Clutches and Brakes The D58 has interconnected, wet steering clutches and brakes for long service life and reliability. The self-adjusting steering clutches are multiple-disc type with a hydraulic booster, ensuring lighttouch joystick movements, while the brakes are the contractingband type that facilitate easy lining replacement.
