  • Empty weight

    This is the dry weight of the trailer when it is empty as supplied by the manufacturer before any extras where added to the build.

    Gross Vehicle Weight Rating

    The GVWR is the total weight of the trailer, plus its load (your tools). This indicates the maximum weight the trailer should weigh when in use.

    Load Capacity

    This means what the trailer can carry. It is calculated by taking the weight of the trailer itself (Empty Weight) and subtracting this from the GVWR.

    Example: If your trailer’s empty weight is 2,425 lbs and the GVWR is 4,409 lbs, you have a load capacity of 2,184 lbs.

    Towing Capacity

    This information is very important as it will determine what size trailer you can tow on the back of your vehicle. This information can be found in your vehicle’s owner’s manual.

    Ball Weight

    Tongue weight is also just as important as your towing capacity, a general rule is 15% of the towing capacity is allowed on the tow ball but this can change depending on the vehicle’s make and model.

  • Storage

    Never store your battery in a discharged state, the battery could continue to lose more power over time and make it difficult to recharge the battery fully if taken too low. Keep your battery fully charged and in a cool and dry place with plenty of ventilation and remember to keep checking on the charge level and recharge if required.

    Charging Your Battery

    Correctly charging your battery is crucial in maintaining performance. Overcharging your battery can damage the internal structure of the battery while undercharging can shorten its lifespan. The trick is to find the correct voltage for your battery, which in the case of AGM deep cycle batteries, is 14.7v. While it is possible to charge your battery using a traditional gas generator, most have insufficient regulators and can damage your battery if left too long. For safe and effective charging, find a good 120v battery charger, charge from the car or consider using a solar panel for a cheaper and cleaner power option.

    Charging from the car

    When charging from the car via the front Anderson plug fitted on your trailer, in most cases it’s best to have fitted a DC-DC charger in the trailer for optimum performance. The reason behind this is most cars now have a low volt output alternator (smart alternator) if you are charging from the car without the DC fitted you may not get a full charge into your batteries due to the low volt output of the alternator, the DC-DC helps generate more power to the battery, so they charge to 100% capacity.

    Charging from the Solar panel

    For cost-effective and environmentally friendly power, consider using a solar system to charge your AGM deep cycle battery. This method is especially useful for those who are without access to grid power.  The power they produce can be run through a regulator set to charge AGM deep cycle batteries. While the fluctuation in power levels of 12v solar panels would damage a battery if left unregulated, using a regulator such as a MPPT Solar Charge Regulator ensures the correct voltage is consistently fed into the battery.

    If your trailer is fitted with a DC-DC that has a solar input, place the solar panels in the sun. You then connect the Anderson plug on the solar panel into the Anderson plug on the side of the trailer (Not through the front drawbar Anderson plug), the DC-DC will have its own built-in MPPT regulator built inside the unit so there is no need for the panel to have one.

    If your trailer does not have a DC-DC charger then the panel needs to be regulated and should be mounted on your solar panel. You will then need to connect the Anderson plug on the solar panel into the front Anderson plug on the drawbar of your trailer.

    Using a Battery Charger / 120-volt installation

    A 120v ‘smart’ charger, such as the Red Arc deep cycle battery charger is a great tool to accurately charge your deep cycle battery. If you have a battery charger mounted in your Trailer and the 120v installation package, plug the charger lead into the powerpoint located next to the charger. When you plug in the 120v 15amp power lead to the side of the trailer this will activate power to all 120v power outlets and the battery charger will light up. If nothing happens, then the 120v trip switch is off and will need to be in its engaged position.

    Make sure the battery charger is set on battery type (Normal) and the amps on (21amps) It can then decipher the voltage that best suits that type of battery, meaning you don’t need to worry about overcharging or even removing the battery from the charger when it’s finished as it will go into float mode once full.

    When you are plugged into 120v power you do not require solar, as the battery charger we just went through is charging the batteries for you.

    Note: We do not recommend leaving the charger running full time 24/7 while in storage unless you have a trickle charge system.

    It is not recommended to take your battery’s power below 40%, sometimes this is unavoidable but try not to take the battery into the red as it can damage the battery cells. If this does happen the battery may not hold its charge again. The more you maintain your battery charge the longer it will last you.

  • Ask yourself, how much value do you place on your business? Uprising engineering’s Pro Trade Series™ has revolutionized what a trailer is and how it can be used. Your trailer is more than a way to haul your tools, it’s also your advertising billboard and what your business represents. Stand out from the crowd. People buy and hire on first impressions as well as emotion, don’t lose the next job just because the other guy looked more professional.

    Invest in the right trailer. Uprising Engineering saw a need for high-quality and innovative trailers. The market has been flooded with trailers built cheaply to attract a volume market based on price. These cheaper trailers often need replacing every five years or so, leading to more money out-of-pocket in the long run. Purchasing a quality-built trailer that might cost a little more up-front but comes out of the box with all the bells and whistles and lasts longer, saves money over time.

    So, what makes the Pro Trade Series™ different? It’s a trailer that will outlast your career if looked after and respected, the build quality and innovative touches in these tradesman’s trailers are like nothing you have ever seen on the market and are designed to be the best construction / contractor / tradesman trailer in the industry. Yes, we understand they aren’t cheap but there is a reason for that, these trailers are built like tanks. The one-piece 4” × 2” rectangular hollow section (RHS) chassis and drawbar makes this trailer very strong. The whole chassis is hot-dipped galvanized for life longevity and is then fully powder coated. The suspension under the Pro Trade Series™ tradesman trailers has 2-inch solid axles with parallel bearings, roller rocker springs, and a dual 12″ electric braking system. With regular servicing and general maintenance, this setup will last a lifetime due to not being maxed out to its limits every day of the week The body sheet material is a galvanized panel, not raw mild steel and the trailer is designed on AutoCAD software and laser cut to millimeter precision. It also has a flush-mounted door and draws with automotive seals and a square design so there is no wasted space. The body of this trailer is fully triple folded, giving the trailer maximum strength but also keeping weight down by not using box tubing for all doors and framework and sheet metal welded over the top that will eventually hold moister over time and rust inside out if not maintained. We use all stainless nuts, bolts, washers, rivets for all our fittings and fixtures. Drawer runner slides are heavy duty and not just fixed on with tek screws or pop-rivets they are all nut-serted with M5 stainless screws. Storage has been very well thought out with huge drawers, shelving, underfloor compartment, and even has a dedicated fridge slide. Running all the gear is easy with our 200amp battery system for running LED lights, charge from the car or solar, run a fridge and mini-oven or even invertor’s to charge your tools batteries while on the job. Fit-out options are endless and we have many products you can add to the build of your tradesman trailer to suit your chosen from our extras list. As you can see the Pro trade series tradesman trailers are premium and built to the highest standard in the industry of tradesman trailer manufacturers, this is a lifelong trailer you only ever need to buy once. Stand out from the crowd, look professional, be organized, invest in yourself, and buy once.
