Safety Concerns Operating dump/roll off type vehicles on uneven terrain increases the chance of rollovers Longer trailers are at a higher risk of rollover during operations Primary hazard is related to the stability of the unit when the box is in the raised position Shifting materials and change in center of gravity can both create dangerous situations: Always be cautious!
A little tilt, a lot of risk! Even a slight slope can be enough to cause tipping, especially if materials shift or stick inside the box.
Factors That Affect Stability Broken or bent leaf springs Improperly loaded container or box Uneven surface when dumping Materials stuck in box Rear wheels settle unevenly or are improperly inflated Excessive wind speed
Tip-Over Prevention Monitor loading to ensure even displacement When unloading be aware that some material comes out faster/slower than others. Raise slowly, and watch and listen for movement. Let load push you out from under it Be aware of uneven surfaces (these areas present the greatest risk of tipping) Maintain accurate tire pressures for all tires Always perform proper pre-trip inspection
Pretreat trailer/box before loading! When available use calcium chloride or salt to pretreat trailer/box before loading. This will help to keep load from freezing up over night if it is a pre- load, and help it from freezing up in transit.
