Popular Post MACKTRUCKS4 Posted February 13, 2016 Popular Post Share Posted February 13, 2016 Just got the new Mack calendar and on the one month is a picture of 2 Superliners with cranes on them. One of them has DUEL front steering axle. I have never seen one before. These belong to Jason Bossert of Kamloops, BC 12 Quote Live every day like it's your last, because one of these days, it will be. Link to comment Share on other sites More sharing options...

bbigrig Posted February 13, 2016 Share Posted February 13, 2016 Dual front steering is fairly common in Canada. It's more common in Quebec where it's been required for heavy power unit gross weights since the 80's. Most of Eastern and far Western Canada doesn't allow for liftable axles so it's easier to go with a heavy second steer axle. Simard Axle from Que. Canada has a patent on the design Mack uses from factory and aftermarket in North America. 2 Quote Link to comment Share on other sites More sharing options...
j_martell Posted February 13, 2016 Share Posted February 13, 2016 I've got the same calendar hanging in the shop. I see lots of twin steers here, but NEVER a superliner.

medicpelle Posted February 14, 2016 Share Posted February 14, 2016 What's the reasoning behind not allowing a drop axle? Quote Link to comment Share on other sites More sharing options...
bbigrig Posted February 14, 2016 Share Posted February 14, 2016 I've seen a few twin steer Superliners in Quebec. All were Dump trucks and the second steer was under the cab. Most are just behind the cab for maximum spread in Eastern Canada. Western needs them further ahead. 1 Quote Link to comment Share on other sites More sharing options...
bbigrig Posted February 14, 2016 Share Posted February 14, 2016 The purpose of going away from liftable axles is road wear. When cornering and a liftable axle is lifted it shifts the weight that axle was carrying to the remaining axles that are grounded. As a test, a fully loaded Mack CV granite was loaded with 22 tons of aggregate in a dump box. The truck had 44K rears and 20K fronts with a 20K rated lift axle. When the lift axle mounted behind the cab was lifted almost 27K pds was shifted to the front axle. The ministries up here figure that spreading the weight on constantly grounded axles will keep the black top longer. Those trucks carrying max gross usually have more then 72"'s of spread on the twin steers and 72" of spread on the drives. Any axles in between must be self steer axles that only lift when empty (controls out of cab) or in reverse through the reverse switch.

russell t Posted February 14, 2016 Share Posted February 14, 2016 Don't forget the bureaucracies with all their engineering expertise when crossing political lines. With a 16 wheel trailer that expands to 10 feet we can legal a 93,000# load, but cross into Oregon and this buys you nothing. Oregon would require 7 or 8 axils to do the same but a 3 axil lowbed trailer in Ca. is almost just dead weight. Quite often long heavy moves on the west coast involve a reload.

BOB DINGSDALE Posted February 14, 2016 Share Posted February 14, 2016 out here they baned them because they would go over the scales with them down then get around the corner and lift them back up. save wear and tear on the tires. 1 Quote Link to comment Share on other sites More sharing options...
