Our involvement in the Solid Waste industry dates back to 1969, when we designed and built the first landfill-based Tippers. Put into service in the city of San Francisco's landfills, they are still unloading trailers today after more than 30 years of continuous operation.

Through a process of continuous improvement in both the design and manufacturing process, Columbia has introduced many features now considered standard in Landfill Tipper design.

The hallmark of our tipper fleet is the patented Low Profile Landfill Tipper, one of the most efficient methods for unloading solid waste at the landfill. The portable yet stable platform can be designed to accomadate most trailers, eliminating the need to purchase and maintain costly self-unloading trailers. The trailer unloading system you once transported is now replaced by solid waste, allowing you to maximize weight savings by moving the greatest payload possible. The results are significantly increased efficiency for more profit over the long haul.

Columbia's Tippers have quickly become the chosen method of unloading solid waste transfer trailers in many landfills across the country and abroad.

The following products serve the solid waste/construction and demolition industry:
• Low Profile Portable Tipper
