Choosing a Base for Heavy Duty Frames
Having trouble deciding on which kind of base to use for your Heavy Duty Frame? Consider the following information:
Casters are not required if you do not move the frame. You may chooses a Flush Frame Base or a Recessed Pontoon Base, which has 4″ of toe space in front. Both bases will add 3.5″ to the height of the frame. Also, both bases are available plain or with a combination of duplex outlet, levelers or anti-tip legs. (Levelers and anti-tip legs must be ordered separately.)
If the frame must be moved, casters are required. You will need to consider how much weight will be loaded and the type of surface the frame will be moved across before you choose the base.
You can select a Caster Base if the equipment and frame weight 800 lbs. or less and will be moved over smooth surfaces. Otherwise, you will need a Caster Dolly or Cabinet Truck. Select an Extended Caster Dolly or Extended Cabinet Truck if heavy equipment will be extended from the front of the frame. Extended Dollies and Trucks protrude 7″ to 16″ in front of the frame face, providing extra stability. Anti-tip legs also work well in this situation.
Caster Dolly vs. Cabinet Truck
A Caster Dolly is made of heavier material that a Cabinet Truck – 11 gauge as opposed to 12 gauge steel. The Caster Dolly accommodates locking casters rather than floor locks. A floor lock will raise the front of the frame about 1/8″, which makes the frame slightly less stable than a a comparable frame on locking casters. For demanding applications, it is best to use a Caster Dolly and locking casters instead of a Cabinet Truck with floor locks.
