New Dash-8 load­ers fea­ture all the lat­est tech­nol­ogy de­vel­op­ments

Ko­matsu Aus­tralia has added two new wheel loader mod­els – the WA270-8 and WA320

8 – to its Dash-8 range. Both fea­ture Ko­matsu’s fourth-gen­er­a­tion hy­dro­static drive trans­mis­sion sys­tem and its ver­sa­tile par­al­lel Z-bar (PZ) link­age sys­tem, which com­bines high break­out forces with par­al­lel lift through­out the lift­ing cy­cle.

The WA270-8 re­places the WA250PZ-6 and has a 111kW Ko­matsu SAA6D107E-3 en­gine, of­fer­ing bucket sizes from 1.9-2.7 cu­bic me­tres. The WA320-8 re­places the WA320PZ-6 and is pow­ered by a 123kW Ko­matsu SAA6D107E-3 with bucket ca­pac­i­ties from 2.3-3.2 cu­bic me­tres. Both are con­fig­ured to Tier 4 Fi­nal emis­sions stan­dards.

Ko­matsu Aus­tralia says it skipped the Tier 4 In­terim-equipped Dash 7 range, go­ing straight from Dash 6 to 8 to en­sure cus­tomers are get­ting the lat­est in emis­sions and fuel-ef­fi­ciency tech­nol­ogy.

“These lat­est wheel load­ers in­cor­po­rate all the tech­nol­ogy de­vel­op­ments in­tro­duced in both the Dash 7 and Dash 8 up­grades, in­clud­ing im­proved per­for­mance and safety, re­duced fuel con­sump­tion, su­pe­rior op­er­a­tor er­gonomics and en­hanced main­tain­abil­ity,” Ko­matsu Aus­tralia na­tional busi­ness manager Richard Fee­hely says.

The Dash 8 mod­els have in­creased straight and full-turn static tip­ping loads (STL) for im­proved pro­duc­tiv­ity and safety. The WA270-8 has a full­turn STL of 8930kg (2.3-cu­bic me­tre ca­pac­ity GP pin-on bucket) and the WA320-8 9780kg (2.8-cu­bic me­tre ca­pac­ity GP pin-on bucket).

“These new load­ers de­liver sig­nif­i­cantly lower costs per me­tre of ma­te­rial moved than their pre­de­ces­sors,” Fee­hely says.

The Dash 8 load­ers have re­designed cab­ins aimed at im­prov­ing vis­i­bil­ity and com­fort while re­duc­ing noise. The cab’s air-sus­pen­sion seat damp­ens ma­chine vi­bra­tions.

“The seat, along with steer­ing wheel, is fully ad­justable for op­ti­mum com­fort and con­trol,” Fee­hely adds. “In-cab noise lev­els at the op­er­a­tor’s ear have been re­duced, down to 68dBA on both, a sig­nif­i­cant re­duc­tion on their pre­de­ces­sor.”
