A slinger truck, also known as a stone slinger, conveyor truck, or rock slinger, is a specialized construction vehicle designed to transport and accurately place aggregates like gravel, sand, and soil at construction sites. The key feature of a slinger truck is its integrated conveyor system, which can quickly and precisely disperse materials in a controlled manner over a considerable distance.

Slinger trucks are commonly used in various construction projects, such as foundation backfilling, pipeline bedding, landscaping, road construction, and erosion control. The ability to disperse materials from a distance helps reduce labor costs, increases efficiency, and minimizes the risk of injury to workers.

These trucks are typically built on a heavy-duty chassis and come equipped with a large storage container for holding the aggregates. The conveyor system is mounted on a hydraulically operated boom, which can be extended, retracted, and rotated to place materials precisely where needed. The operator controls the conveyor system from a remote control station, allowing for adjustments in real-time.

The distance a slinger truck can shoot material depends on the specific model and configuration of the conveyor system. Generally, slinger trucks can accurately place materials at distances between 50 to 100 feet (15 to 30 meters) or more. Some high-capacity models may even have a reach of up to 150 feet (45 meters) or more.

The actual shooting distance of a slinger truck may be affected by factors like the type and size of the material being dispersed, the angle of the conveyor belt, and the operating conditions at the construction site. To ensure safe and efficient operation, it's essential to follow the manufacturer's guidelines and recommendations when using a slinger truck.

Slinger trucks are known by several different names, which may vary depending on the region or specific application. Some alternative names for slinger trucks include:

Stone slinger
Conveyor truck
Rock slinger
Aggregate spreader
Material placement truck
These names typically refer to the same type of construction vehicle, which is designed to transport and accurately place aggregates like gravel, sand, and soil using an integrated conveyor system.

A CAS® Slinger, often referred to as a “Stone Slinger” uses a conveyor system to rapidly and accurately place material up to 15x faster than conventional equipment.

The volume of material that CAS Slingers can hold Varys by model and configuration. Slinger trucks such as the FatBoy and EZ Flow can hold between 18 - 40 yards. Off road slinger equipment like the AT7 holds 7 yards. No matter that holding capacity, the use of a reloader allows the slinger to be fed continuously.

CAS Slingers are a great way to place material in hard to reach areas. The AT7 and Drag’n Off-road Slingers can place material at a distance of 150′. Slinger trucks, such as the FatBoy and EZ Flow, can place material up to 130′ away.

The FatBoy is available in three sizes:

• FB22– Capacity: 22 cubic yards *(32 yards)
• FB24– Capacity: 24 cubic yards *(35 yards)
• FB27– Capacity: 27 cubic yards *(40 yards)

A half ton truck can carry approximately 2000 lbs of gravel, which is equivalent to 1 cubic yard of gravel. However, modern half-ton trucks can carry up to 1,500 lbs, which is equivalent to 0.75 cubic yards of gravel.

The coverage area of a ton of gravel can vary widely depending on the size and shape of the gravel, as well as the thickness of the layer you spread it in. As a general rule of thumb, a ton of gravel can cover around 80 to 100 square feet at a 2-inch depth.

In general, a semi-trailer can carry up to 25 to 30 tons of gravel. However, the amount of gravel a semi can haul varies depending on several factors, including the weight limit allowed in the area where the semi is operating, the size of the semi-trailer, and the density of the gravel being transported.

At a depth of 3 inches, 1 yard of gravel should cover approximately 100 square feet or a 10ft x 10ft area.

The FatBoy is available in three sizes:

• FB22– Capacity: 22 cubic yards *(32 yards)
• FB24– Capacity: 24 cubic yards *(35 yards)
• FB27– Capacity: 27 cubic yards *(40 yards)

The EZ Flow can carry 18 yards.

3/4 In. Minus Crushed Quarry is ideal for driveways because it compacts very well which allows for greater stability as vehicles drive over it.

The first layer of larger stones should be laid down at a depth of around 4-6 inches.2. The second layer stones the of 2-3 inches In total, the depth of a standard gravel driveway should be around 6-9 inches. However, for areas with heavy traffic or poor soil conditions, the thickness of each layer should be increased accordingly to provide better stability and durability.

To keep your gravel driveway from sinking, you'll need to take steps to ensure that the surface remains stable and even over time:

1. Install a solid base: The foundation of your driveway is critical to its long-term stability. Make sure that the base layer is properly graded, compacted and at least 6 inches deep. This will provide a solid base for the gravel to sit on.
2. Use the right size gravel: Using the right size of gravel for your driveway is also important.
3. Install landscape fabric: Install landscape fabric over the base before adding the gravel to prevent weeds from growing and reduce erosion.
4. Add more gravel: Over time, gravel can settle and become compacted, leading to a sunken surface. Add more gravel to your driveway as needed to maintain an even surface.
5. Regular maintenance: Regularly rake and smooth out the gravel to prevent uneven areas, and remove any debris or vegetation that may cause erosion.
6. Avoid heavy loads: Avoid parking heavy equipment or vehicles on the gravel driveway for long periods of time as this can cause sinking and create ruts in the surface.

Typically, larger dump trucks can carry about 28,000 pounds or about 14 tons. On average, smaller dump trucks can transport around 13,000 to 15,000 pounds or 6.5 to 7.5 tons.
