The idea
|
Marc Grue, inventor of the Double Trolley, explains how the project started:
"Jazz bassist Jesper Carlsen had converted a laundry basket trolley into a transportation device for his double bass (see left). I borrowed it from him and rolled my bass with it to and from orchestra rehearsals and concerts.
At that time I was looking for a high, adjustable stool to sit on, but I couldn't really find one high enough. One day I was looking at the laundry trolley and thought: It should be possible to put a seat on the top!" |

Marc Grue continues:
"I dropped another rebuild of the laundry trolley and went on with the possibilities of making a collapsible combined stool and trolley.
After a while I imagined the horrifying scenario of how the two legs (or rather wheels!) could roll out from under me during a concert!!
I therefore explored the idea of taking off the wheels instead. This was the birth of the Double Trolley and I started to work on the first prototype."
See how the prototypes of the Double Trolley were modified and improved over a period of 5 years! |

I am amazed at the marvelous engineering that has gone into the design and construction of the Double Trolley.
I can't wait to use it on the job.
You are to be commended for your contribution to the brotherhood of double bassists. Bless you!
