Cat re­designs three ar­tic­u­lated haul trucks

Cat has up­dated three of its ar­tic­u­lated truck mod­els with a range of new fea­tures. The three mod­els – the Cat 730, 730 EJ (ejec­tor) and 735 – have re­ceived new op­er­a­tor sta­tions, new con­trols, trans­mis­sion-pro­tec­tion, hoist-as­sist, ad­vanced trac­tion con­trol, sta­bil­ity-as­sist and a new fuel-sav­ing ECO op­er­at­ing mode.

In ad­di­tion, the new 730 and 730 EJ have been given au­to­matic re­tarder con­trol and a hill-start fea­ture. These par­tic­u­lar items were al­ready present on the 735’s C-Series pre­de­ces­sor and the up­dated 735 re­tains them. All three mod­els are pow­ered by a Cat C13 ACERT diesel, with the 730 and 730 EJ rated at 274kW and the 735 at 319kW.

The new op­er­a­tors’ cab fea­tures an ex­ter­nal ‘spinal-ROPS’ de­sign that uses a rear-quar­ter glass panel that elim­i­nates the need for a rear struc­tural pil­lar, en­hanc­ing vis­i­bil­ity. Cat says the over­all cab de­sign re­sults in a 7dB(A) re­duc­tion in noise inside the cab.

The con­trols inside the cab have also seen a sig­nif­i­cant up­grade, with a new com­bined trans­mis­sion-and-hoist lever that al­lows sin­glelever con­trol of ve­hi­cle speed and body-hoist­ing func­tions. A switch al­lows op­er­a­tors to choose ei­ther man­ual or as­sisted hoist­ing con­trol, with the lat­ter au­to­mat­i­cally ap­ply­ing the wait­ing brake, shift­ing the trans­mis­sion to neu­tral and rais­ing the body to its max­i­mum an­gle at en­gine high idle.

An­other new fea­ture of the up­dated trucks is Cat’s Ad­vanced Au­to­matic Trac­tion Con­trol sys­tem, which can proac­tively ap­ply dif­fer­en­tial locks to avoid wheel spin.

The new mod­els also fea­ture a ‘ter­rain-based’ throt­tle-smooth­ing sys­tem that pre­vents ac­cel­er­a­tion surges when trav­el­ling over rough ter­rain that makes keep­ing steady pres­sure on the throt­tle pedal dif­fi­cult.
