I was talking to a contractor friend today about the guy bringing fill sand to my jobsite. The trucks coming to my site are 10-12 yd tandem dumps. My friend is from another part of the country, and he is used to seeing dumptrucks with lift axles. I'm in South Texas, and tandems seem to be the norm here. Me no habla espanol, so asking the drivers anything is like talking to.....oh, nevermind.
How much load capacity do lift axles add to a tandem dump? How much tare weight does a lift axle add? Would it be cost-effective to run fewer trips with a larger, more expensive, quad axle truck versus more trips with a cheaper tandem?
I'm just curious if we're "behind the times" here.
