Container selection usually starts from litres, and that is where the most common site problem comes from: equipment of the right volume that will not go through the door. So the building is measured first, and volume is chosen only among the models that fit.

  1. Clear opening of the narrowest door: the gap between frame and leaf with the leaf fully open.
  2. The highest threshold and the ramp slope.
  3. The narrowest corridor where a turn is made, and the lift car.

A corridor often takes the container but not the corner: a body whose long side approaches the corridor width can only turn at an angle, and scrapes the wall. A container that will not go into the lift upright has to be laid down, which disturbs the product inside.

Add working clearance to GEBHARDT's external dimensions and compare them with the narrowest opening; for handles and projections, ask Aris Makina for the project drawing. Whether the castors clear the threshold is tested on the same walk-through.

A door's name does not give its clear opening: the passage gap of a so-called 90 cm door is narrower by the frame, the thickness of the open leaf and the latch. So the person who knows the site measures it with a tape and adds the figure to the order file.
