Abstract
The present invention relates to a vacuum wall crawler having at least one vacuum track unit comprising a track frame, two pulleys provided in opposite ends of the track frame, and defining a wheelbase, an endless track arranged to circulate on the two pulleys, and comprising a flexible band, said flexible band comprising a plurality of apertures, and having a thickness, a vacuum distribution box provided in said track frame wherein the vacuum distribution box is in communication with a portion of the apertures to distribute a vacuum to the portion of apertures as the endless track circulates, where the thickness of the flexible band is 5-20% of the wheel base.

A vacuum wall crawler having at least one vacuum track unit comprising:
- a track frame;
- two pulleys provided in opposite ends of the track frame, and defining a wheelbase;
- an endless track arranged to circulate on the two pulleys, and comprising a flexible band,
- said flexible band comprising a plurality of apertures, and having a thickness;
- a vacuum distribution box provided in said track frame
- wherein the vacuum distribution box is in communication with a portion of the plurality of apertures to distribute a vacuum to the portion of the plurality of apertures as the endless track circulates,
- the flexible band is an outer band, the endless track further comprising an inner band, said inner band having suction holes allowing vacuum to pass between the vacuum distribution box and the portion of the plurality of apertures, and
- the outer band and the inner band are made of different materials.
