The inclines all consist of two parallel rail tracks with a gauge of . Boats are carried on carriages that run on these rails. The inclines rise from the lower level of the canal to a summit and then down a second shorter incline to the upper canal level. The first part of the main incline and the short upper incline were both built at a gradient of 1:24 (4.2%). A carriage is lowered down the incline to counterbalance an upward moving carriage. Once the downward moving carriage has reached the summit and started down the main incline its weight helps pull up the upward moving carriage. This allowed the slope of the incline for this section to be built at a steeper gradient of 1:12 (8.3%).
