Wobblin-Goblin Posted February 5, 2016 Share Posted February 5, 2016 It pulls the tarp over the load and then back again when empty. Quote Link to comment https://www.bigmacktrucks.com/topic/43907-question-about-mack-dump-trucks/#findComment-323152 Share on other sites More sharing options...
seyser Posted February 5, 2016 Share Posted February 5, 2016 That's the arm for the roll up tarp that covers the dump box. Quote Link to comment https://www.bigmacktrucks.com/topic/43907-question-about-mack-dump-trucks/#findComment-323153 Share on other sites More sharing options...

tjc transport Posted February 5, 2016 Share Posted February 5, 2016 to be more specific, that is the arm used by a power tarping system to cover and uncover the load.there is one on each side of the body, and springs on the bottom of the arm where the pivot point is on the body.then there is an electric motor on the cab shield to wind or unwind the tarp.

Underdog Posted February 6, 2016 Share Posted February 6, 2016 So if it's quick and powered and automatic, why do I see so many inconsiderate dump truck drivers going down the road loaded with the tarp open?!?

Red Horse Posted February 6, 2016 Share Posted February 6, 2016 thank a lot from you.You are welcome- and the reason for this is in this country we have all kinds of clean air laws. These covers are supposed to keep dust and dirt from blowing off of the load while the truck is moving Quote Link to comment https://www.bigmacktrucks.com/topic/43907-question-about-mack-dump-trucks/#findComment-323195 Share on other sites More sharing options...
Popular Post Joe Ditchkus Posted February 6, 2016 Popular Post Share Posted February 6, 2016 Tarps also help from buying new windshields. 4 Quote Link to comment https://www.bigmacktrucks.com/topic/43907-question-about-mack-dump-trucks/#findComment-323202 Share on other sites More sharing options...
Popular Post Mackdaddy2030 Posted February 6, 2016 Popular Post Share Posted February 6, 2016 Cause people are lazy. I see many by me that have power side roll or power cable systems and they never use them. You should use it all the time!!! One for keeping debri from coming off and two for fuel mileage. Only time mine is open is when I'm getting loaded. Run with it empty and you won't have as much air drag. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/43907-question-about-mack-dump-trucks/#findComment-323203 Share on other sites More sharing options...
57 bcr Posted February 9, 2016 Share Posted February 9, 2016 I used mine all the time for the idiots that followed too close and tried to blame me for a broken windshield on their vehicles,just to find out I had sand on. The tarp satisfies the law even though most of the "high speed aggregate projectiles" that hit said windshields , are in the tread of your DOT approved tires. Before they were a must, the use of mine saved me a bunch of B.S. by Johnny Law. One of the best investments in equipment I ever made. Oh and mine was the hand cranked version with the spring loaded arms. Good to stick your head out of the cab every now and then,as situations can change!!
