Assembly – Table is made from 3 assemblies & sub-assemblies
a) Bottom stand Pi type structure with table top, drawers etc.
b) Hind rectangular box, also called as switch box, to hold 1
sources etc. c) Optional top side rectangular box mounted on top of Hind or
switch box to house various instruments like CRO, FG, & power suppliers etc.
Frame: 16 slide MS square tube (Heavy duty) Colour: Brown / Off white powder coating, optionally sturdy aluminum profile/frame.
Table Top Material /colour:
The nova pan or Rubber wood with white/Silver gray with smooth finish veneer finish table top (18mm thick optionally 40mm)
Drawer: Drawers to have two position options: Horizontal (optional) or vertical (Default). Horizontal drawers have restriction of height else they will obstruct knees of tall person while sitting in front of table. Vertical drawer has limitation of no. of students which can be accommodated in front of table i.e. only one but advantage here is bottom drawer can be heighted.
– Out of 3 drawers, one is open type & would double up as PC keyboard
carrier with mouse pad on its side. Other two drawers are closed type,
lockable. Of these two, bottom drawer has double height to
accommodate tall (pneumatic/hydraulic) components.
Dimensions: Upper Drawer: 400 mm (L) X 480 mm (W) X 190 mm (H)
Tall Drawer : 400 mm (L) X 480 mm (W) X 600 mm (H)
