Disconnecting a Mobile Operations Center (MOC) trailer requires a methodical approach to ensure safety and prevent damage to the trailer, the towing vehicle, or yourself. The process involves carefully unhitching the trailer, disconnecting electrical and safety systems, and securing the trailer for storage or future use. Following the steps outlined in this guide will enable you to perform this task confidently and efficiently.
Safety First: Prior Preparations and Precautions
Before even thinking about touching the hitch, prioritizing safety is paramount. Failing to do so can lead to serious injury or damage.
-
Secure the Area: Ensure the area around the MOC trailer and towing vehicle is clear of people, pets, and obstacles. A level surface is ideal to prevent the trailer from rolling.
-
Chock the Wheels: This is arguably the most important step. Place wheel chocks behind the tires of the trailer, on both sides if possible, to prevent any unintended movement once the trailer is unhitched. This is especially crucial on even the slightest incline.
-
Safety Glasses and Gloves: Debris and sharp edges are common around trailer hitches. Wear safety glasses to protect your eyes and gloves to protect your hands from cuts and grease.
-
Disconnect Power (If Applicable): If your MOC has a power supply separate from the towing vehicle, disconnect it at the source before disconnecting from the tow vehicle. This avoids potential electrical hazards.
The Disconnection Process: Step-by-Step Instructions
With safety protocols established, proceed with the disconnection procedure:
-
Lower the Landing Gear: Locate the landing gear, usually two adjustable legs located near the front of the trailer. Use the crank handle to lower the landing gear until it firmly rests on the ground. Ensure the landing gear is stable and evenly supports the front of the trailer. You want the front end of the trailer to bear some weight before uncoupling from the tow vehicle, but not enough to make it hard to operate the hitch mechanism.
-
Disconnect the Electrical Connector: Carefully unplug the electrical connector from the towing vehicle. This connector provides power for the trailer’s lights and brakes. Secure the connector to the trailer or hitch to prevent it from dragging on the ground and getting damaged. Consider using a small rubber cap to protect the connector prongs from corrosion.
-
Disconnect the Safety Chains: Safety chains are a critical safety feature. Unhook the safety chains from the towing vehicle’s hitch receiver. Ensure the chains are properly stowed and will not drag on the ground. Consider using S-hooks with spring latches for added security.
-
Release the Hitch Latch: Locate the hitch latch or coupler on the trailer’s tongue. This mechanism secures the trailer to the ball hitch on the towing vehicle. Unlock the latch and raise it to release the coupler from the ball. Some hitches have a simple lever, while others may have a more complex locking mechanism. Familiarize yourself with your specific hitch type.
-
Raise the Trailer off the Ball Hitch: Use the landing gear crank handle to further raise the trailer slightly off the ball hitch. Ensure the ball hitch is completely clear of the trailer’s coupler.
-
Disconnect the Breakaway Cable: The breakaway cable is a vital safety feature that activates the trailer’s brakes if it becomes detached from the towing vehicle. Disconnect the breakaway cable from the towing vehicle. Be absolutely sure to connect this correctly before towing again in the future.
-
Move the Towing Vehicle: Carefully move the towing vehicle forward, away from the MOC trailer. Ensure there is sufficient clearance between the vehicle and the trailer before driving off.
-
Stabilize the Trailer (If Necessary): If the trailer is equipped with stabilizer jacks, lower them to provide additional stability and prevent rocking. These jacks are typically located at the rear corners of the trailer.
Post-Disconnection: Securing and Maintaining Your MOC Trailer
Once disconnected, take steps to protect your investment and ensure it’s ready for its next deployment.
-
Cover the Hitch: Consider covering the exposed hitch on the towing vehicle with a hitch cover to protect it from the elements and prevent injury.
-
Level the Trailer: Use levels to ensure the trailer is perfectly level lengthwise and widthwise. Small adjustments to the landing gear and stabilizer jacks may be necessary.
-
Regular Inspections: Periodically inspect the trailer’s tires, brakes, lights, and other components to ensure they are in good working order. Pay particular attention to rust and corrosion, especially if the trailer is stored outdoors.
Frequently Asked Questions (FAQs)
Here are some common questions regarding disconnecting MOC trailers:
FAQ 1: What tools do I need to disconnect a MOC trailer?
You’ll typically need a wheel chock set, gloves, safety glasses, the correct size wrench or socket (if needed for hitch adjustments), and potentially a level for ensuring proper leveling after disconnection. A rubber mallet can be helpful for stubborn hitches.
FAQ 2: How do I know if my landing gear is strong enough?
Consult the manufacturer’s specifications for your specific MOC trailer. The landing gear should be rated to support the weight of the trailer, especially when loaded. If you are unsure, contact the manufacturer directly.
FAQ 3: What if my hitch is stuck and won’t release?
Try rocking the towing vehicle slightly forward and backward to relieve pressure on the hitch. You can also try lubricating the hitch ball and coupler with penetrating oil. If it’s still stuck, inspect for any visible obstructions or damage.
FAQ 4: How often should I lubricate my hitch and landing gear?
Lubricate your hitch and landing gear regularly, especially before and after each use, or at least every six months, depending on the environment and frequency of use. Use a high-quality grease specifically designed for trailer hitches.
FAQ 5: What should I do if my MOC trailer has air brakes?
Disconnecting air brakes requires additional caution. After chocking the wheels and lowering the landing gear, you’ll need to release the air pressure from the trailer’s air brake system. Consult your MOC trailer’s manual for specific instructions. Usually there are valves that need to be closed or pulled to release the pressure. Never disconnect air lines under pressure.
FAQ 6: How do I protect my MOC trailer from theft?
Use a hitch lock to prevent unauthorized towing of the trailer. Consider installing a GPS tracking device for added security. Also, park the trailer in a well-lit and secure area.
FAQ 7: Can I disconnect my MOC trailer on a sloped surface?
It is strongly advised against disconnecting a MOC trailer on a sloped surface. The risk of the trailer rolling is significantly increased. If unavoidable, take extreme precautions and use multiple wheel chocks. Have a spotter present to monitor the trailer.
FAQ 8: What if my breakaway cable is damaged?
Replace the breakaway cable immediately. A damaged breakaway cable is a serious safety hazard. You can purchase replacement cables at most trailer supply stores.
FAQ 9: How do I store the electrical connector properly?
Use a protective cover to shield the electrical connector from the elements. Secure it to the trailer frame to prevent it from dragging on the ground. You can also apply dielectric grease to the pins to prevent corrosion.
FAQ 10: Is it okay to leave the landing gear extended indefinitely?
While leaving the landing gear extended is generally acceptable for short-term storage, it’s advisable to support the trailer frame with additional supports (like jack stands) for long-term storage. This reduces stress on the landing gear and helps prevent settling.
FAQ 11: What if I can’t find the correct size wrench for the hitch?
Most trailer hitches use standard-sized wrenches. Check your owner’s manual. As a general rule, it is always best to bring a full wrench and socket set with you as part of your MOC trailer’s emergency kit.
FAQ 12: What are the potential risks of improper disconnection?
Improper disconnection can lead to serious injuries, damage to the MOC trailer or towing vehicle, and potential safety hazards if the trailer is not properly secured. Always follow the recommended procedures and prioritize safety. Failure to properly chock the wheels can result in a runaway trailer. Failure to properly disconnect electrical could lead to shocks or fires.
