Height

Calculate height needed to elevate trailer tailgate to meet dock.

NOTE: Based on location of rear wheel, trailer tailgate could rise more than ramp's actual height.

Use steps below to determine required riser height:

A + B = C

A = Height of Trailer + Height of Riser Ramp at center of back wheel.

B = Measure length from center of back wheel to tailgate and multiply by rise that corresponds to your ramp and truck sizes:

RAMP HEIGHT 3.6-5.8 METER (12-19 FOOT) BOX TRUCK 6-8 METER (20-26 FOOT) BOX TRUCK
15 cm (6") Tall Add 1.25 cm (1/2") Rise
per 30 cm (1')
Add 0.80 cm (5/16") Rise
per 30 cm (1')
20 cm (8") Tall Add 1.60 cm (5/8") Rise
per 30 cm (1')
Add 1.10 cm (7/16") Rise
per 30 cm (1')
30 cm (12") Tall Add 2.50 cm (1") Rise
per 30 cm (1')
Add 1.40 cm (9/16") Rise
per 30 cm (1')

C = Height of Tailgate where it meets dock.
