    The First Tri60 T1

    5,000 lbs Safe Dolly

    We disconnected our TriWich from our Heavy Duty 18,000 lbs/tire Semi-Truck Wheel Dolly and added a tow hitch (Seamless tube) to the back. This safe was our first test to see if it woudl work. Work it did with 2" square tube and 2" angle bars . Application with Angel Bar Dolly: Safes, Washers, Dryers, Refrigerators.

    Throw in some Tri-Ways and Tri-Bars and you could safely move Pool Tables, Glass Tables, etc.

    The First Tri60 T3

    8,000 lbs 40ft Shipping Containers on Sand with Pneumatics

    From Safes, we went straight to a 40 ft. shipping containers with 18" pneumatic casters on sand. For the first time our T1 showed some stress, so we doubled our TriWich from 3/16" to 3/8"


    Pneumatics are the most demanding casters which is when US Navy and US Airforce called us after this video. We developed the SpindleWich and V-Wich for the military. At the same time AT&T contacted us and we developed CaddyWich and Tri-Jack Requests for tractors and forklift naturally followed. ForkWich Plus we had constant request for a highway system LiftWich

    Modular Mobility Connectivity

    Once you build a modulare Tri60, then you connect everything you can imagine to it making it standardized and 100% modular.

    TriWIch Tri60s connects directly to:

    Any-Wich - Machinery or Wooden Sheds adapter

    Tri-Lug - Shipping container connector (20,000 lb/Tri60)

    WMD03 - Modular Wheel Dolly Arm 18" (3,700 lb/tire) Ultra-Low

    WMD06 - Modular Wheel Dolly Arm 28" (6,000 lb/tire) RV

    WMD18 - Modular Wheel Dolly Arm 28" (18,000 lb/tire) Semi

    Tri-Bars - From 5" to 96" (build your own moving platform)

    Other fun ones to know:

    Tri-Ways - The Directional Connectors

    Creating a retro dolly your standard dolly into a dolly you actually want, only requires some simple connectors we call the "Tri-Ways":

    • Tri-Way-HX - Horizontal (H) Opposite (X) Direction
    • Tri-Way-HI - Horizontal (H) In-line (I) Direction
    • Tri-Way-VX - Vertical (V) Opposite (X) Direction
    • Tri-Way-VI - Vertical (V) In-Line (I) Direction

    These can be used to retrofit your old dollies, pull shipping container and for a multitude of different applications.

    Tri-Bars - Standard Modular Bars

    Mother necessity is the root cause of many of our products. We have serveral standard Tri-Bars now.

    • Tri-Bar-05 - 5" (BaseWich)
    • Tri-Bar-14 - 14" (BaseWich)(LiftWich)
    • Tri-Bar-28 - 28" (BaseWich)(DoorWay)(Wheel Dollies)
    • Tri-Bar-40 - 40" (Wheel Dolly)
    • Tri-Bar-45 - 45" (Engine Hoist)(Shipping Container)Interchange Tri-Bars with a BaseWich to obtain to hold Containers 5" to 45" off the ground

    Axle / Chassis Dollies

    After Shipping Containers with our new pneumatic casters, we pondered what else the pneumatic system could be used for. How about Axle Wheel Towing Dollies? Yes, picking up our truck was simple.


    We will continue to recommend our wheel dollies for safety. Longer bars begin to bow, which affects the levelness of the casters. It will be more noticable on smaller casters, although pneumatic caster will remain unaffected.
