This lighter and smaller version of the Strong Boy will come in handy in many situations.
When loading the Strong Boy with truss, use it together with its mini version so you can ride the loaded dolly up a ramp without any difficulties. 
Besides using it in combination with the Strong Boy, you can also use two mini dollies at the same time to transport truss 30.

The Strong Boy mini is compatible with trusses that have a center-to-center distance of 239 mm (30 truss), including Prolyte, Eurotruss, Global Truss, and LITEC.
