Many companies make dump truck liners. They are almost necessary gear for any hardworking dump truck given that they protect the truck and aid in releasing sticky loads. To really appreciate dump truck liners, though, you have to drive a dump truck. Better yet, you should drive a dump truck that does not have a dump truck liner. You'll quickly see how materials can scar up a dump bed and how sticky loads can take their toll on hydraulic systems. I have driven my fair share of dump trucks, and none of them had dump truck liners.
Because none of my trucks had dump truck liners, I spent a lot of time researching and dreaming about what kind of dump truck liner I would buy if I had the choice. I finally settled on plastic dump truck liners. One year I worked on a snow removal crew. My job was to follow a loader around in my dump truck. Once my bed was full, I would go drop my load of snow and try to hurry back to keep the loader busy. The worst part about the job was when snow stuck to my bed, which was more often than not. I don't mean a couple little clumps of snow in the corners, I mean the whole bed-full of snow would just stick in my bed.
When the sticking was the worst, I would have to lift my bed five or six times and bang on the bottom of the bed with a sledge hammer to release the snow. Other guys on our crew had dump liners, they had much fewer problems and were constantly suggesting to me that I should get a liner. I agreed but could do nothing at the time. Another time I was driving a truck for a gravel company. Again, my truck did not have a liner. Hauling and dumping gravel all day every day really did a number on my bed. Within two years, the abrasive rocks had scraped away my paint job, created weak spots all over my bed, and opened up the metal to the ravages of corrosion. My co-workers didn't have to tell me that I needed to buy a liner; it was painfully obvious that unless I wanted to buy a whole new dump bed, I needed to find a liner that would work for me. I looked at spray-on liners and metal liners for a long time.
I liked that spray-on liners were easy to install and seamless. Because there was no seam, I didn't have to worry about water penetrating the liner and getting down into my bed to create pockets of corrosion. I didn't like that the spray-on liners were not as much help with releasing sticky loads. Metal liners, I found, are durable, but would still require special treatment in order to help release sticky loads. I did not want to have to pay for a liner and then the treatment to make it release sticky loads. Having decided against both spray-on liners and metal liners, I finally decided to go with a plastic liner. This was not any ordinary plastic, though.
The liners I looked at promised to be more durable than steel yet easily release even the stickiest materials in any conditions. The promise that my liner would be durable and would be all I needed to release sticky loads was music to my ears. I was convinced. I bought a plastic liner for my truck. Within a few short weeks, my truck was the envy of my co-workers. They all had dump truck liners for their trucks, but they couldn't help but see that my liner was tough and slippery--in other words, perfect.
