Transporting grand pianos and upright pianos is a special profession, it needs extraordinary skills due to the sizes and weight. Before you order a transport please ascertain that the team consists of the right professionals. The following article contains some details and a video about transporting the Essex grand piano of the Piano School.

This video was prepared on 06/06/2014, about the transportation of the Essex grand piano which is in use now. Only manual transport was available due to the little space.
The Pianoplan is a stair-climbing dwvice with two engines. It makes the transport easy but int needs 35-40 cm more height above the grand piano set on its edge.
It isn't possible to turn with a longer grand piano on a narrow staircase, it happens to lift it with a crane.
