When transporting heavy equipment such as aerial lifts, ensuring that the equipment can safely ascend and descend trailer ramps is crucial. The JLG 40-F is a popular model in the aerial lift family, and one common concern among operators and equipment owners is its ability to climb the inclined surface of a trailer's dove-tail ramp. So, what’s the optimal incline angle for this type of equipment, and what factors should be considered when loading and unloading aerial lifts?
What is the JLG 40-F?
The JLG 40-F is a 4WD diesel-powered articulating boom lift designed for use in construction, maintenance, and other heavy-duty industries. With its 40-foot working height and 500-pound lift capacity, it's built for tough, off-road conditions. It features a compact design that allows it to maneuver in tight spaces, making it an ideal choice for tasks like window washing, light construction work, and high-reaching tasks in both urban and rural areas.
Trailer Dove-Tail Inclines: What You Need to Know
The dove-tail incline of a trailer refers to the sloped surface at the rear of the trailer, designed to help machinery drive onto and off the bed. The angle of this incline varies based on the design and purpose of the trailer, but it’s often a significant concern when transporting heavy equipment.
For an aerial lift like the JLG 40-F, the incline’s degree can be a determining factor in whether the equipment can safely drive up the ramp without damaging its drive system or becoming stuck.
What Degree of Incline Can the JLG 40-F Climb?
Typically, the incline of a trailer ramp is measured in degrees. For an aerial lift such as the JLG 40-F, the maximum safe incline that it can climb is around 15 to 20 degrees. This is based on several factors including the equipment’s drive capabilities, ground clearance, and weight distribution. The actual degree of incline the lift can handle depends largely on its drive system and tire traction.
Why is the Incline Limit Important?
To ensure safe loading and unloading of the JLG 40-F on a trailer, here are some tips:
One operator recalls a job where they had to move a JLG 40-F onto a trailer with a 25-degree incline. Despite the 4WD system, the equipment started slipping halfway up the ramp. After a few attempts, they realized the tires had low pressure, reducing traction. After inflating the tires to the recommended PSI and using a spotter, the equipment was able to climb the ramp successfully. This example emphasizes the importance of checking all components and conditions before attempting to load the equipment.
Another scenario involved a construction company moving multiple aerial lifts, including the JLG 40-F, across different job sites. On one occasion, the equipment was loaded onto a trailer with a ramp that was nearly 20 degrees, and although it was manageable, the operator noticed that the hydraulic system began to strain. After speaking with the equipment supplier, it was advised to reduce the incline or add a secondary ramp to spread out the load more evenly.
Alternative Trailer Considerations
If the incline is consistently an issue, it might be time to consider alternative trailer options:
When loading and unloading heavy equipment like the JLG 40-F, always prioritize safety and machine integrity. The degree of the trailer ramp’s incline plays a critical role in maintaining the equipment's longevity and performance. If the incline seems too steep, take the time to adjust the conditions or equipment setup to ensure safe and effective loading. By following these tips and understanding the capabilities of your machine, you can prevent costly damage and ensure smooth operations on every job site.

This is based on several factors including the equipment’s drive capabilities, ground clearance, and weight distribution. The actual degree of incline the lift can handle depends largely on its drive system and tire traction.
Why is the Incline Limit Important?
- Drive System Integrity: If the incline is too steep, the drive motors or hydraulic systems could strain, leading to potential overheating or mechanical failure. For the JLG 40-F, which has a 4WD system, the stress on the system increases with steeper inclines.
- Stability and Safety: Too steep an incline can affect the stability of the machine while driving up the ramp. The JLG 40-F has a relatively high center of gravity, and while it's designed for off-road conditions, excessive slope increases the risk of tipping or losing control during loading or unloading.
- Tire Traction: The condition of the tires is another crucial factor. Inadequate tire traction can result in slippage, especially when the incline is steep or when the surface is wet or slippery.
To ensure safe loading and unloading of the JLG 40-F on a trailer, here are some tips:
- Assess the Trailer’s Incline: Before loading, always assess the trailer ramp's incline. Use a digital inclinometer or a smartphone app to measure the angle of the ramp. Aim for a maximum of 15 to 20 degrees. If the incline is steeper, consider using a different trailer with a gentler ramp.
- Use a Spotter: When driving the JLG 40-F onto the trailer, always use a spotter. The spotter can help guide the operator and ensure there’s no danger of the equipment tipping or colliding with the trailer’s edges.
- Drive Slowly and Steadily: When moving up or down the ramp, maintain a steady speed and avoid sudden acceleration or braking, as it can cause instability or even lead to accidents. If the equipment struggles with the incline, it’s essential to slow down and reassess the angle or surface condition.
- Check Tire Pressure: Ensure the tire pressure is within the manufacturer’s recommended range. Under-inflated tires can reduce traction and stability, making it harder to navigate steep inclines.
- Use Ramp Extensions If Necessary: If the trailer’s incline is too steep, consider using ramp extensions to reduce the angle. This simple addition can provide a safer incline for the JLG 40-F to climb without overloading its drive system.

Alternative Trailer Considerations
If the incline is consistently an issue, it might be time to consider alternative trailer options:
- Low-Profile Trailers: These trailers are designed with a lower bed height, allowing for a gentler incline and easier loading for equipment like the JLG 40-F.
- Hydraulic Tilt Trailers: These trailers use hydraulic systems to adjust the angle of the loading ramp, providing more control over the incline and minimizing strain on the equipment.
