Abstract
A new transportation cart is provided that separates each reticle box or container from other reticle boxes contained in the cart. The transportation cart provides additional shock absorption, thus eliminating effects of vibration of the reticles, the transportation cart is equipped with ESD protection and provides improved security to the transported reticles.
Claims6
A component transport cart, comprising:
- (a) a lower portion, said lower portion comprising:
- (i) wheels providing capabilities of motion to said transport cart;
- (ii) a platform being substantially planar and having a bottom surface and a top surface opposite said bottom surface, said wheels being directly attached to and disposed underneath said first bottom surface of said platform;
- (iii) shock absorbers, being mounted over and directly joined to said top surface of said platform and having vertically oriented axes;
- (b) an upper portion disposed over said shock absorbers, said shock absorbers forming an interface between said platform and said upper portion, said upper portion comprising:
- (i) a front surface being located in a plane;
- (ii) a back surface being parallel with said front surface;
- (iii) a planar bottom surface being orthogonal to said front and back surfaces and directly joined to said shock absorbers;
- (iv) a top surface being parallel with said bottom surface;
- (v) a left surface being located in a plane orthogonal to said planar bottom surface:
- (vi) a right surface being parallel with said left surface;
- (vii) upper portion dividers provided in a plane parallel with said left and right surfaces;
- (viii) component box support units being mounted in a box support plane and capable of supporting a component box, adjacent rows of component box support units being separated by a distance, said component box support units:
- (1) extending from said front surface of said component cart to said back surface of said component cart:
- (2) being arranged along said upper portion dividers and said left and right surfaces;
- (3) including cushioning units arranged over a surface of said component box support units;
- (4) including said box support plane angled with respect to said planar bottom surface;
- (ix) a set of two sliding doors mounted in a plane of said front surface of said component cart;
- and
- (x) a handle attached to said upper portion, enabling motion of said component cart wherein said platform has a height substantially less than a height of said upper portion.
