Section 2: Balance Beam Lengths

There should be room to walk round between the end of the beam and the edge of the quadrant. Under no circumstances should the beam overhang the quadrant

This example is at Stockton Brook top lock on the Caldon Canal

This even worse example, where the overhang is over a steep flight of stone steps at Trentham lock on the Trent & Mersey canal

   Even this innocuous looking overhang forces the operator off the quadrant
  ...while this beam which overhangs the water is equally dangerous
