Identifying and Understanding Snow Gates for Snow Removal Equipment

[MikePhua]

Snow gates are a crucial part of snow removal equipment, used primarily to control and direct the flow of snow during plowing operations. Whether for municipal use, large-scale commercial properties, or residential areas, the right snow gate can make a big difference in the efficiency of snow removal efforts. In this article, we will explore the various types of snow gates, how to identify them, their features, and the best practices for maintaining them.
What is a Snow Gate?
A snow gate, also known as a snow deflector or wing, is a piece of equipment attached to snowplows to help control the distribution of snow. The primary purpose of a snow gate is to prevent snow from spilling over the edges of the plowed area, thus keeping the snow confined to the intended area, such as the road or parking lot. Snow gates are especially useful in urban areas with tight streets, where excessive snow piling on sidewalks or private properties can become a problem.
These devices are often used in combination with other plow accessories such as v-plows or straight blades, helping the plow achieve better results by containing the snow in the correct area.
Types of Snow Gates
Snow gates come in several variations, each suited to different plowing needs. The most common types include:

1. Hydraulic Snow Gates
   These snow gates are powered by hydraulic systems, making them adjustable during plowing operations. They offer precise control over how much snow is pushed to the side, making them ideal for areas where snow buildup can be problematic, such as near driveways, curbs, and sidewalks.
   • Features:
     • Fully adjustable during operation
       
     • Can be raised or lowered with ease
       
     • Integrated with the plow’s hydraulic system
       
     • Provides better snow containment on uneven surfaces
       
2. Manual Snow Gates
   These gates are operated manually and are often found on smaller plows or older models. While they lack the adjustability of hydraulic gates, they can still provide effective snow management for basic plowing tasks.
   • Features:
     • Manual operation with simple controls
       
     • Requires physical effort to raise or lower
       
     • Less expensive than hydraulic models
       
3. Spring-Loaded Snow Gates
   These gates use springs to maintain a constant pressure against the snow, making them more effective in situations where automatic hydraulic systems may not be necessary. The spring-loaded design allows for some flexibility when encountering obstacles, preventing damage to the equipment.
   • Features:
     • Self-adjusting to some degree
       
     • Easier to operate than fully manual gates
       
     • Less maintenance than hydraulic systems
       
4. Swinging Snow Gates
   These gates are mounted on a pivoting arm that swings outward to direct snow away from sensitive areas. They are commonly used on larger plows for roadways with heavy snow removal demands.
   • Features:
     • Provides large coverage area
       
     • Swinging mechanism allows for easy deployment
       
     • Suitable for heavy-duty plowing
       

Identifying the Right Snow Gate
Identifying a specific snow gate can be challenging, especially when there is limited information or when you are working with second-hand equipment. Typically, snow gates will have markings or labels that provide valuable information. If you're unsure of the type, here are some steps you can take to identify it:

1. Look for Manufacturer Tags or Stamps
   Most snow gates will have a manufacturer’s plate or a stamped serial number located on a part of the frame or near the base. This can give you the make, model, and sometimes the year of manufacture. Common manufacturers include brands like Boss, Meyer, and Western, which are known for producing high-quality snow gates.
   
2. Assess the Design and Functionality
   • Hydraulic snow gates will often feature hydraulic hoses and connectors, which are easy to spot.
     
   • Manual gates are typically more simple in design with no hydraulic components.
     
   • Spring-loaded gates will have a visible spring mechanism.
     
   • Swinging gates will have a pivoting arm and may also include a control system for operation.
     
3. Examine the Mounting System
   Snow gates are mounted to the plow frame, and their mounting system can provide clues to the model and brand. Examine how the gate attaches to the plow — is it through a pin system, brackets, or a hydraulic actuator? This will help in narrowing down the type of gate.
   
4. Consult the Owner’s Manual or Service Records
   If you have access to the equipment’s owner’s manual or service records, it is often possible to find the exact specifications of the snow gate used. These records will also provide maintenance information and troubleshooting tips.
   

Common Issues with Snow Gates
While snow gates are built to withstand the harsh conditions of snow removal, they can encounter a few common issues. Understanding these problems can help ensure the longevity and functionality of the equipment.

1. Hydraulic Failures
   In hydraulic snow gates, leaks or issues with the hydraulic pump or cylinder are common. Regular inspection of the hydraulic lines and seals is essential to prevent malfunctions. Over time, hydraulic fluid can degrade, leading to poor performance, so it’s crucial to replace the fluid and filters according to the manufacturer's recommendations.
   • Solution: Check hydraulic lines regularly for leaks and replace any damaged hoses. Also, ensure the hydraulic fluid is topped up and in good condition.
     
2. Spring Tension Loss
   For spring-loaded snow gates, over time, the tension in the springs can weaken, causing the gate to be less effective at controlling the snow. This issue is more common in older units.
   • Solution: Re-tension the springs or replace them with new ones if they have lost their elasticity.
     
3. Worn Pivot Points
   Swinging snow gates often experience wear at the pivot points, especially if the gates are frequently moved in and out of operation. This can lead to reduced range of motion or failure to fully engage the snow deflection.
   • Solution: Regularly lubricate the pivot points and replace any worn components. Ensure the arms are aligned and not bent or damaged.
     
4. Physical Damage
   Snow gates, especially those operating in tough conditions, can suffer from physical damage due to impacts with curbs, vehicles, or other obstacles. This damage may include bent frames or broken attachments.
   • Solution: Inspect the frame and attachment points regularly. Repair or replace damaged parts to maintain the gate's effectiveness.
     

Maintaining Your Snow Gate
Proper maintenance is critical to keep snow gates working efficiently. Here are some key maintenance practices:

1. Regular Inspections: Perform routine checks to ensure that the hydraulic components, springs, and pivot points are functioning properly. Look for wear or damage, especially after each snow removal operation.
   
2. Lubrication: Lubricate moving parts such as pivot points and springs to reduce friction and prevent rust.
   
3. Hydraulic System Maintenance: Check hydraulic fluid levels and replace filters as recommended by the manufacturer. Also, inspect hoses and connections for any signs of leaks or wear.
   
4. Cleaning: Clean the snow gate after each use to prevent ice build-up and ensure smooth operation the next time it is needed.
   

Conclusion
Snow gates are essential tools for managing snow removal, especially in areas where snow accumulation can be a major problem. By understanding the different types of snow gates, their features, and how to identify and maintain them, you can ensure that your snow removal operations run smoothly and efficiently. Regular maintenance and timely repairs can extend the life of your snow gate, making it a reliable tool in harsh winter conditions.
Whether you are operating municipal snowplows, handling smaller residential equipment, or working with heavy-duty commercial units, snow gates can help streamline snow management and reduce the risk of unwanted snow piles.
