The length of the boat should be no longer than 14FT, and max Loading capacity should not exceed 500Lbs if using by hand, or max loading capacity should not exceed 750Lbs if using by motor vehicle. Otherwise, it may be too heavy for yourselves moving or cause injury.

QUICK RELEASE DESIGN: The completed product has a quick-release design except for some U brackets that should be bolted on the tongue or shaft permanently. We use quick-release buttons to help build the main frame quickly and we use lots of quick-release lock pins to build the dolly system. In the meantime, it will provide many quick-release adjustment options for the boat hand dolly. So even though the product is heavy, it is still easy to carry and provides a wide range of support, and is very flexible for different boats.

Hand Dolly can be operated in full-size mode with 3 tongue sections (length about 12ft) or short mode by reducing the middle tongue unit (length about 8ft). 2).

About the Wheel Pressure

The safety working pressure range for most applications should be 15-25 PSI. We suggest inflating all the 8" & 16" wheels to 20 PSI only. When the pressure drops down to below 15 PSI in a few months, you can top up the pressure to 20PSI.  Also, a regular car tire portable inflator is good for inflation and pressure measurement. Putting 20 PSI should be always safe since already given enough space for the wheels. And remember the sunlight and heat will bring the pressure up a lot.

It is your option to install the front wheel. If you want dolly can stay on the ground solid, you can remote the front wheel but only keep the round pole as the stand. Since it has no bearing for the front wheels system, so the front wheel system only work on a flat and solid surface.  

Pump up your wheels: When after your one winter storage or new product is received, you need to top up the air to 20 PSI with a small digital inflator, the same kind of portable 12V electric inflator for automobiles or bicycles will be suggested to use.

Attentions - Wheel tube damage may be related to the below reason

  • Pressure below 10 PSI, the inner tube is easy to be damaged during use
  • Pressure over 20 PSI, the inner tube could be damaged when sunlight or heat brings the pressure up.
  • Using a strong inflator like the air pump in a gas station, the inner tube is too small when facing the strong airflow. it could be damaged in seconds.
