Skid steer loaders are workhorses on construction sites, and hydraulic motors are the heart of their powerful and versatile functionality. Let's delve into how these motors operate within skid steer loaders and explore the common types used
The Powerhouse of Skid Steers Hydraulic Motors
Similar to other hydraulic machinery, skid steer loaders rely on a hydraulic system for power transmission. Here's a breakdown of the process
Engine Power An internal combustion engine generates the primary power for the skid steer loader.
Hydraulic Pump This pump converts engine power into pressurized hydraulic fluid.
Hydraulic Motors Strategically placed throughout the machine, these motors convert the pressurized fluid back into rotary motion (shaft rotation).
Precise Control By controlling the flow and pressure of the fluid, the operator precisely regulates the speed and direction of each motor, enabling smooth and controlled operation of various functions.
Why Hydraulic Motors Are Ideal for Skid Steers
High torque, low speed Skid steer loaders excel at tasks demanding immense strength at slower speeds, such as pushing heavy materials, digging trenches, or lifting massive objects. Hydraulic motors perfectly deliver this crucial power characteristic.
Independent Drive System Each track (or wheel) of a skid steer loader can be powered by a separate hydraulic motor. This allows for independent control, enabling the machine to turn sharply by varying the speed of each track (skid steering). It also provides excellent maneuverability in tight spaces.
Compact and Powerful Hydraulic motors offer a high power-to-size ratio, allowing for efficient use of space within the skid steer loader's compact frame.
Durability Built to withstand the harsh conditions of construction sites, these motors can handle heavy loads, dirt, dust, and extreme weather.
Common Types of Hydraulic Motors in Skid Steer Loaders
Gerotor Motors A popular choice due to their affordability, simplicity, and reliable high torque output at low speeds. They are widely used for driving the independent tracks (axial piston motors are gaining some traction for this application as well). (e.g., HANJIU OMR series)
Axial Piston Motors These offer high efficiency and precise control, making them suitable for powering high-demand attachments like hydraulic breakers or industrial mowers. They might also be used for track drives in some high-performance skid steer loaders.
Specific Applications of Hydraulic Motors in Skid Steer Loaders
Track Drives (Independent) Hydraulic motors power each track independently, allowing for the skid-steering maneuverability that skid steers are known for.
Attachment Operations Many skid steer loaders utilize hydraulic motors to power high-pressure auxiliary circuits. These circuits provide power to a wide range of attachments, including
Buckets for loading and digging
Augers for drilling holes
Trencher attachments for digging trenches
Cold planers for removing asphalt
Snow blowers for clearing snow
Pallet forks for lifting and transporting materials
Additional Points
The specific type and size of the hydraulic motors used in a skid steer loader depend on the machine's size, power rating, and intended applications.
Modern skid steer loaders often incorporate variable displacement hydraulic motors. These allow for adjusting the motor's displacement based on the task at hand, optimizing performance and efficiency.
By understanding the role and different types of hydraulic motors in skid steer loaders, you gain a deeper appreciation for the technology that empowers these machines to be versatile and powerful tools on construction sites.
