Dy­na­pac’s new as­phalt paver comes with a choice of drive sys­tem

Earthmovers & Excavators - - News -

Dy­na­pac has re­vealed the new SD1800W and SD1800C as­phalt pavers, which are wheeled and tracked ver­sions of the same model and fea­tures im­proved lev­els of op­er­a­tor com­fort, re­duced run­ning costs and lower emis­sion lev­els.

The new pavers have op­er­at­ing weights be­tween 10.3 tonnes (wheeled) and 10.5 tonnes (tracked) and fea­ture a 4.8-cu­bic-me­tre hop­per and a lay­ing ca­pac­ity of 350t/h.

Both units are pow­ered by a 2.9-litre 54kW

Deutz diesel en­gine and Dy­na­pac says they have a max­i­mum paving speed of 25m/min and a max­i­mum travel speed of 4km/h.

Both ma­chines have a sl­id­able, tiltable and height-ad­justable op­er­a­tor con­sole as well as load-sens­ing hy­draulic pumps.

The two pavers use Dy­na­pac’s PaveMan­ager

2.0 soft­ware which can au­to­mate cer­tain paving and mem­ory pa­ram­e­ter func­tions as well as the crown and slope set­tings, min­imis­ing the po­ten­tial for re­work.

To place ma­te­rial, the new paver range uses Dy­na­pac’s new V3500 screed which the com­pany says pro­vides ‘un­equalled sta­bil­ity’. Dy­na­pac’s V se­ries screeds can dou­ble their width us­ing the hy­draulic ex­ten­der.

They also use Dy­na­pac’s safe-im­pact push roller sys­tem that min­imises shock (and dam­age) to the screed from bump­ing the truck. Ma­te­rial flow is con­trolled by pro­por­tional sen­sors, en­sur­ing smooth flow along the con­veyor and min­imis­ing auger re­ac­tions to avoid ma­te­rial seg­re­ga­tion.

The con­veyor it­self is a 700mm-wide du­al­bar feeder type, con­trolled by pad­dles on the op­er­a­tors’ sta­tion.

The new pavers have auger widths of be­tween 1.71m and 3.15m, have 320mm di­am­e­ter cast flights and are height-ad­justable to 200mm.
