Whether it's time spent cleaning out the bodies of off-highway haul trucks, or bodies that aren't reaching their full capacity potential on each load, carryback costs mining operations around the world millions of dollars in lost opportunities each year. Now, washing your hands of all sticky materials you haul in favor of new non-sticky materials is neither a viable option nor very practical. The good news is, there are ways to cut-down on the carryback and time spent scraping out the bodies! The right equipment can be the difference in millions of dollars in lost opportunities or millions of dollars in your operation's pocket. Here's are some things to consider when making a decision on equipment for operations hauling sticky or homogenous materials.
Trying to decide on a body for a haul truck in an operation where sticky materials are being hauled can be one giant haul-truck sized headache. Not all bodies are created equal, which is especially true in operations with highly homogenous materials. Customized bodies for your operation are an option to consider wisely. With a body engineered specifically for the sticky materials in your operation, the walls of the body could be tapered with an outward angle to help the sticky material move out of the body, rather than get stuck.
Rear Eject Bodies are ideal for sticky material that clings to the off-highway haul truck and begins building up. The ejector blade pushes the hauled material out of the body, pushing out even the most adhesive of the homogenous materials. Rear Eject Bodies are unique in that they are useful in the most difficult of operations. Low overhead clearance, operating in areas without stable or consistent ground footings, sticky materials, hilly terrain - all of these are applications where a Rear Eject Body excell.
Nemesis to many an operation: Carryback
Additions to your existing equipment can also help combat hard to get out materials. Since most carryback starts building up where the walls intersect and cohesive material can cline on several surfaces at once , hydrophobic steel lining problem areas (like corners) can cut down on the amount of material that sticks to the walls without compromising the capacity of the body
Load Ejectors are another addition you can make to an existing body. Load Ejectors are a simple, mechanical way to minimize material sticking to the front slope and floor within truck bodies. In the dump cycle, the Load Ejector pulls away from the body floor, hanging vertically or nearly vertically, to dislodge sticky material. Load Ejectors can also be used in conjunction with Tailgates and Sideboards boost productivity even farther.
Carryback is a problem that persists in mining operations worldwide, but the right equipment decisions for your operation can definitely cut down on the sticky materials clinging to your off-highway truck bodies. Be it a special body engineered for your specific operation, or the equipment you can add to your existing off-highway haul truck bodies, these options can save your operation many lost opportunities.
