Why Dealers and Customers Love Sudenga’s Shallow Double Drive Over (SDDO)

There are several disadvantages to installing a traditional dual receiving pit. First off, they require a very deep hole to be dug, which can only be achieved through significant excavating work, yards of concrete and rebar, and hours of on-site fabrication and equipment installation. The equipment that accompanies these deep pits requires more height and operational horsepower. As a result, deep dual inlet pits are often very expensive to install and maintain. Ground water seepage can become a very serious issue with these installations as well. Safety is also a concern, as confined space entry is required when repairing or cleaning the equipment and pit.

Fortunately, Sudenga’s Shallow Double Drive Over is not like traditional dual receiving pits. Our system gives the installer the choice of how deep they want to install a system into the ground. In some cases, the unit can be installed on grade, requiring only site leveling. Another solution is digging a shallow trench, often less than four feet deep. This shallower pit requires significantly less rebar and concrete than a traditional pit. Our SDDO also provides easy access to equipment, which is often as simple as removing a grate section. Our entire system is modular, so it can fit a variety of site layouts and applications.

IMPROVE SAFETY & EFFECIENCY: Our SDDO requires less dirt work and excavation, so less time and resources are necessary to install. Installation is easier as well, as most of the installation work is done on grade. Less support equipment is necessary, like cranes and backhoes, as the drive over equipment can often be installed with smaller lifting equipment—no need to dig big holes.

The equipment surrounding low-profile pits is typically less expensive, as heights are shorter because equipment can be installed on grade. Lastly, eliminating a deep pit ensures that personnel are not required to enter a confined space to clean or repair equipment associated with the grain pit.
