Here’s everything you need to know about our rock slinger, including how it can help you finish your projects on time and within budget.

What Is A Rock Slinger?

A rock slinger is a tool used on trucks to deliver and spread out a variety of construction materials. Like a dump truck, a rock slinger will dump materials off at a location. But unlike a dump truck, rock slingers deliver materials with precision and in difficult to reach places that a dump truck could never get to.

While the beds of dump trucks tilt over to dump out the materials, a hopper and conveyor belt are used to deliver materials from the bed of a rock slinger truck.

Common materials delivered by our rock slinger truck include:

  • Gravel

  • Sand

  • Rock

  • Soil

  • Mulch


Our rock slinger accurately launches streams of aggregates or soil at high speeds from a hopper body into a specified location. It uses a radio-remote-controlled variable-speed conveyor belt system that can rotate in any direction to dump, spread, or ‘throw’ aggregate up to 100 feet away from the truck.  Our slinger can also sling up high enough to reach over a single-story house.

Types Of Projects Our Rock Slinger Truck Is Used For

Materials Northwest's rock slinger truck is used for a variety of residential and commercial projects that require you to move large and often heavy volumes of aggregate and soil from one location to another quickly and efficiently.

It's most commonly used for projects requiring precision placement of soil and aggregates in hard-to-reach areas, such as over fences, down steep slopes, on the inside and outside of foundations and used for the following projects:

  • Residential and commercial construction

  • Installing playground surfaces

  • Formwork

  • Sidewalks

  • Driveways

  • Parking lots

  • Pool backfill

  • Septic tank backfill

  • French drain backfill

  • Weeping tile backfill

  • Landscaping

The bottom line is if you can’t deliver your construction materials quickly with a dump truck, a wheelbarrow, or by hand, and your project requires the precision placement of your aggregate or soil, then you need our rock slinger truck to get your project completed on time and within budget.
