Heavy Haul Truck Specifications and Features
Jason CuddyHello and welcome to another episode of the Transportation Exchange podcast presented by Rush Truck Centres of Canada . I'm your host , Jason Cuddy , and on today's episode we welcome back Adam Bajric , who's account manager here at Rush . Adam , welcome back to the podcast .
Adam BajricThanks for having me .
Jason CuddySo we had John before talking about , you know , heavy haul application and just kind of an overview of what we have product wise . And today I thought we dig into a little bit deeper , kind of application by application which truck , what model , what specs and features ? You know , to help kind of people walk through how do I spec it ? What's changed ? What are some trends we've seen ? So you know , I thought we'd start off kind of right off the bat with a tractor , heavy haul tractor . If I'm looking to get into this world , what am I looking at ? You know , powertrain will start there .
Adam BajricYeah . So I mean for the heavy haul side of things , for Navistar , we'd start with the HX chassis . So , be it 620 or 520 , if you're looking for a shorter turning wheelbase or a longer turning wheelbase , getting more weight on the axle and getting yourself in compliance with SPF Gotcha , so we'd start off with the HX chassis as the bare bones and then we'd throw in , basically , a Cummins X15 powertrain . Usually we run the performance series on heavy hauls . Guys like it . That you can , you know , play with it . You can bump up horsepower in the long run , you can tune it a little bit more compared to the productivity or the economy style classes .
Adam BajricWith that being said , on the performance series , guys usually run in the 565 horse , 1850 foot pounds of torque . You can bump it to a 2050 foot pounds or you can go even up to the 605 if you really want that big boy power . And then we usually pair it with an automatic transmission . The stigmatism , you know , of keeping the manual and the big shifters and whatnot . Yeah , there's still some guys that want them . But , as you know , finding drivers is getting harder and harder and we find that there's a big transition to the automatic stages .
Adam BajricSo , with that being said anything , that's usually if you have a gross combination weight of , you know , under 140,000 pounds or up to , I should say I guess , 140,000 pounds , you can run an Allison transmission , six speed . You don't tons of pulling power , anything over that we'd have to switch , usually over to an Eaton Endurant XD . Gotcha , they just released the pro last year or this year I should say . Awesome transmission , lots of features and functionalities . Now a lot of guys like the 18 speeds over the six speeds . They find like they're getting better fuel mileage on them . Whether or not which one's true , it's more driver preference . Both are great . The new Endurant XD actually has a school thing with you remember , with your manuals , even in a car you can kind of roll it out of a snow bank . Yes , well , they got this thing called the rock free switch now , which gives it the same kind of programming and feel to rock yourself out of a whole truck stock .
Jason CuddyNice , yeah , so I guess . So we've got that , we've got some power train going , we got transmission . What are we pairing that to as far as the axles ?
Adam BajricYeah , so the axle wise I mean Navistar offers Dana and Meritor axles . The most common one is Meritor and the reason behind it is is back in the day there was these axles called Rockwells , and Rockwell actually got perched out by Meritor and they're known for the big round diff cover on it . Guys love them , they're reliable and whatnot . Usually for heavy haul tractors we're going anywhere from a 16 to a 20,000 pound front axle and 46,000 pound rear for suspension . Most guys now are going with air suspension just for a more comfortable ride . You know auto leveling and so forth . We carry the Primax bags . They're an awesome off road bag , really reliable . But you still got some guys that want mechanical and we will join them with mechanical .
Jason Cuddybut I've never really seen anyone not like airbags once they go that way , gotcha , and so we've got all that and obviously a lot of concern when you're calling that much weight is , you know , the frame capacity kind of frame ticket ? You know what are the different options ? I know there's double and single . What do you see ?
Adam BajricSo Navistar's done a great job now with basically I mean both both frame options are available . There used to be a lot of single frame can't hold it . Our new single frames are capable of 3.5 million RPM , which is overkill , as is . We're running them primarily in the dump truck application , which we'll talk more about later , and the heavy haul family . You'll see guys that are hauling the big , you know oversized , overweight permit loads . They're double framing it .
Jason CuddyGotcha .
Adam BajricThe only downside about the double frames . I mean , yes , they go up to 4.5 million RPM , but you have , you know , the Canadian winter salt , because splitting in the long run , so what you want longevity out of , I mean , you know , if you take care of your stuff , yeah , it's gonna last a long time , but you know you got to take that into consideration .
Jason CuddyFair . So we've got kind of the underpinnings go in . Obviously , the HX model had a refresh recently . What's kind of new and improved inside for the drivers ?
Adam BajricSo the HX cab got a full redesign . So we're talking now . We took an LT cab but just beefed it up so you got kind of like the style of car doors where there's no clickety clank anymore . You've got the new diamond elite interior , which is fantastic . It's got , you know , leather stitched seats he didn't cool seat options , swivels If you got a sleeper . You know leather wrapped wheels , a lot of creature comforts that guys are wanting . So you know . And then on the outside we've come . You know twin air cleaners , dual stacks , single stacks . You know you got chrome sunshades , big chrome Texas style bumpers , lots of little creature comforts in that sense . And then also you know you got your standard Alcoa Derb right that everyone loves and a lot of other . You know little key things , keyless entry and so forth .
Jason CuddyNice . And a neat feature , at least through Navistar , is you know we can put most of that stuff in from the factory but there is also the ability to add more stuff after the factory , before it gets to the dealership .
Adam BajricYeah , so we got this thing called TSE , which is a truck specialty center , and it's basically literally the building next door to Navistar's the factory line , and you can basically put in special requests . So you know steerable lift axles , fixed lift axles for the heavy haul guys . You know half round fenders , full round fenders . You want a 72 inch aeroslide for the guys that really got to get the weight up front . You know you want to put a hydraulic tank , split tanks , lights , beacons , headache racks , and you can use suppliers , even that are in Ontario . They'll ship down to there . Navistar is a great job of you know hiring them or you know subbing them out and bring them down . So there's a lot of things to kind of free up our shops up here and get the truck over to you faster .
Jason CuddyNice and so okay . So I've got a tractor built . You know what do I need to put in the back of it ? It is dependent on what I'm hauling , like whether it's a float or a live bottom like . What are the nuances and differences that we need to consider there ?
Adam BajricSo if you're doing into like float tractors , live bottoms and dumps , a lot of those require wetline kits you know for us at Rush we use multiple suppliers , we use gear power over in Mississauga , we use drive tech out in the East End . There's guys up north as well . If you're doing you know , live bottoms , you usually need like a combination wetline kit . If you're doing just you know floats , you need only like a single stage . So there's a lot of options like that . Then you got guys that need more flow , less flow , bigger hydraulic tanks , lesser hydraulic tanks . Some guys need extra switches .
Adam BajricSo you know , if you're in the heavy haul world , you got this fourth axle , you want that on a switch . The heavy haul world is a little different than your live bottoms and your end dumps , where they're not exactly spiff compliance because everything is permitted . So you know you're allowed to have switches and cabs on on your float tractors , not for aggregate , not for live bottoms . It's a different world and a lot of people get that kind of confused and say yeah , I can have switches or no , I can't . So there's a lot of little things there that you can play with , but that would be the key features of making it work .
Jason CuddyNice , okay , so I've got that under control . So say , now I'm looking at the , the dump truck world we'd be talking about briefly maybe let's kind of do something , let's walk through . Okay , I want to . I want to get myself , you know , a new jump tuck and working out what . What am I looking at there from model engine transmission ?
Adam BajricYeah . So the most common for our dump truck line is the HX620 . It's a setback axle which guys love because dump trucks are in the city a lot . They want a tighter turning radius . Standard wheelbase on those is a 256 inch wheelbase . You know we're running a 20 or 20 and a half foot dump body . We're running a spiff 23, . You know you're running a 20,000 pounds steer axle on it . We usually pair it with a 425 tire
Spec Options and Applications
Adam BajricInside .
Adam BajricMost of the guys want the fully loaded interior . You know , because , again , drivers are in this truck all day , every day . So you know diamond elite interior . You know twin air cleaners , twin stacks , all done up and whatnot . Now , if you're doing , you know the lot of the dump truck guys are into paving and whatnot , so they need to put the pintle hook on the back to pull , you know , a tag along or whatnot , or even a pony pup setup there's . There's a lot of options there that you can play with , but that's kind of like . You know our standard spec In terms of engine wise .
Adam BajricWe run a productivity series for that application , usually 500 horse . Some guys really think that you know pulling pups and what they should be at 565 , but we've really seen had great success with the 51850 productivity series great fuel mileage , great pulling power , and most guys say they burn the tires off anyways with that kind of horsepower . So it's been a great success . And then transmission , nine times at 10 guys pairing it now with the 4500 series , allison yes , if you're a long hauler like on Sorry , like aggregate hauler pulling a pup , some guys prefer to go the 18 speed , but both will do it because you're at that 140 or under , like we were talking before on the heavy haul side , right Suspension , most guys again , now we're kind of transferring over to the air suspension , to we're running Primax bags .
Adam BajricThere is some mechanical guys and I mean , for reasons , if you're , if you're a big like condo excavation guy , a lot of guys like to run the HMX . Suspension tends to give a little bit better grip coming out of the hole and any rough , rough terrain and whatnot Catch . So it helps out a lot too , you know . Then the other thing we can talk about , as well as more , so you know , for running a steerable lift axle or a twin steer , and again it works depending on what the application is Both of them .
Adam BajricThere's not one that's better than the other . It both serves different applications , right .
Jason CuddyNo , it's fair . Yeah , and then I guess it's your wise . Similar to what was on the day cab , as far as you know , fit feature and options available . Right . Yeah , same same product line and just comes down user preference for the most part .
Adam BajricYeah .
Jason CuddyExcellent , and then so from a body point of view , obviously that is application specific as well , right , so , I need to know what am I hauling ? What were we ? Steel versus aluminum ? What's ? What's the sweet spot of those ?
Adam BajricYeah . So you know if you're an aggregate hauler , you know you're a ton miler , as they call it . You're usually running an aluminum body . You know we sell at rush the Cobra lineup and we have both the air wall and post and panel Summer for looks . Some of you save a little bit of weight . They're both great . They're awesome for getting the volume on your truck . Now if you're hauling , you know rubble , dirt , a mix of everything . Guys tend to go to the steel bodies . We now carry the Bullrock lineup which has been awesome . A lot of guys tend to go in the city . They call it GTA spec . Yep , they run a 46 inch wall at the 48 inch tailgate . It's kind of like the perfect medium for all around for dirt , asphalt , all that kind of fun stuff .
Jason CuddyAll right , cool . And I guess another application that maybe we see a bit more of like because it has a bit more versatility but isn't maybe a common one , is , you know , like the roll off hook lift setup and that I guess gives us a mix of opportunities for product line , kind of what do you see ? Guys are going to that world .
Adam BajricYeah , so you're , we're still running like , depending on what you're doing on the , on the big side , we're still running HX's , and then it varies from if you're doing tri axle , tandem or single axles . Right Right now , you know same thing for , like the dump truck , I'm kind of running the same kind of spec in terms of engine power chain and suspension , for you know roll offs . Now , if you're going into tandems and singles , it's just basically . It's now comes down to motor and wheelbase transmission on the MVs and HVs that we offer . Hvs were usually running in tandem spec and then MVs were running in single , single axles configurations . But usually on the HVs you can either run well , now it's trans transitioning , but we had the 826 and the HV 613 .
Jason CuddyRight .
Adam BajricAnd now it's switching over to the S13 , which is going to be really exciting to see out on the road shortly . There's also the ability to run the Cummins L9 and the HV 607 , which has been a truly well built engine . Lots of guys have them on the road and on the MV you can go from the V6 , 7 Cummins or the L9 as well . You can really make some big horsepower on it . In terms of transmissions , on those two units most guys are running a 3000 RDS . It gives you live PTO capabilities , which is awesome . For those that don't know , it's basically you know . It allows you to back up while your trucks and gear to get under that bin , which for most bin guys that are getting into the business , they go . Well , I don't need to roll under your truck . Well , if you're working on somebody's really high end driveway and you know you drag a bin by accident , stuff one up .
Adam Bajricyou're going to be paying a big price to repair it , so better to have that kind of capability . You know the PTO provision for and being able to roll under the truck Gotcha .
Adam BajricYou know , and then , if we're comparing between roll off and hook lift , there's a lot of , you know , question on what should I do ? Should I do a hook lift ? Should I do a roll off ? Because both are in the bin business . Some guys you know you still seeing running around with the common rail system , you know from John and Sons or Capital . And then you have other guys that are transitioning to , like the Atlas Polar . You know , high up hook lifts , right , both have a purpose . If you're in the bin business and you're running anything from basically a five yard up to a 50 yard bin , you can basically make a triaxle , do all those bins together , gotcha . But if you're not in the bin business and or sorry , if you're , yeah . If you're not in the bin business and you're just , you know , looking for a great system , the hook lifts is nice .
Adam BajricThe only downside of , I'd say , the hook lift versus the roll off is that you're limited to bend lengths . So your truck's going to be used to only carrying . You know , if you're , we'll use tri-axles for comparison speaking , but comparable , sorry . You're only going to be running like a 20 and a 40 yard bend on a tri-axle setup . You can't go into the five or 10 yards that your standard roll off would be Gotcha . But on the plus side you can parallel park your bends .
Adam BajricYou can do a lot of easy pickups and stuff where it's handy . So it really depends on what you're doing . I sell a lot of hook lifts to guys that are in the excavation demolition game because they're allowed hook lifts . Which is funny is this roll off is not allowed into the , into a lot of dump sites for dirt because the way they're shaking the bends out they don't get a proper dump angle . Guys got to come out , open the swing doors and all that With all . As the hook lifts you can go into dump sites , which usually pisses off the roll off guys when they get turned back .
Jason CuddySo yeah , no , fair yeah . So it really comes down to application specific and what you're trying to do and real understanding the market . You're playing in and then fairing out the sweet spot with regards to that . Yeah , so , from product-wide , you mentioned a couple like who , who are the kind of the companies that offer kind of both options that we play with ?
Adam BajricIn the GTA or Ontario . The biggest guys for roll offs you know as John and Sons they're over in Oakville . You've got Capital as well . That's in that side of town On Trucks is out west . There's a few other smaller guys that are getting into it now . For the most popular hook lifts in the city, you got Atlas Polar , you got Palfinger , you've got the Swap Loader by Drive Products as well , and there's a couple other guys that are also entering the game . But those are kind of like the big , big names that you see rolling around everywhere , gotcha .
Jason CuddyWhat I find is when you get into application , you know , especially when we're spec'ing the truck , it's nice to pull those guys in right and have them talk with their customer and say , okay , what's your application ? Because they , you know they'll see current trends , they'll have a different model line that's come out right , and and then they'll help you spec the truck out too . Right , make sure you've got the right wheel base , make sure the axle ratings are , and they'll do the whole weight analysis for you , right . So make sure that .
Jason CuddyOkay , if you want to run a certain yard bin in this application , you know , maybe we got to move from tridem to a tandem or whatever it is you're trying to do or you know , find that sweet spot , so it is nice you can pull them in and have them do that part of it as well . No , absolutely .
Adam BajricAnd one of the one of the nice things too . I tell guys all the time when speccing trucks is , they go . How do you know like which one's better ? If I'm going to hook lift , you know , is it better for me to go Atlas Polar or Swap Loader or Palfinger , and I go always . Guys , the best thing to do even though there might be one brand that outdoes the other , the best thing is just to find out what supports you the best . If you're out West and Brantford , you're probably better to deal with the FRF Right . If you're out in the East End and you're close to Atlas Polar , they're probably the best guy because they're around the corner from you .
Jason CuddyThey break yeah you need support , you need support right , and that's the thing is having a good support network with the vendors that we use and the products we support , plus with Navistar directly as well . So
Other Considerations
Jason Cuddygood point . Well , hey , look , thanks for coming in kind of doing a walkthrough of the different application we get to , the heavy spec , certain things to consider and look at and kind of what the trends are that you're seeing . We really appreciate it . Hopefully it gives everyone a general idea of looking at a new truck or a certain application or getting into a different application , things to be asking and to be considering . So I appreciate that . Yeah , thanks , Excellent . Hey , that concludes today's episode . We want to thank Adam for joining us and to catch up on past episodes .
