Capacity
Gross total weight of loads and handling equipment should
be determined in the selection of Dock Leveler capacity.
In order to provide a proper margin of safety,
consideration should also be given to the moving impact
made by the gross load when traveling across the Dock l
eveler. The number of shifts and subsequent duty cycles
during which the Dock Leveler will be used is another
important consideration in choosing a Dock Leveler.
Contact your local Rol-Lift representative to discuss
the Dock Leveler capacity required for your application.
Frequency of Operation
High use areas or multiple shift operations where Dock
Levelers are used continually may warrant consideration of
heavier duty units, or hydraulic operation to reduce total
lifetime cost.
Dock Height
Dock height will determine the grade percentage from dock to vehicle. The
general selection criteria is the maximum grade percentage from dock to
vehicle: when using electric powered handling equipment it is 10%, and for
gas or diesel powered equipment 15%. Exceeding these grade percentages may
result in equipment "hang up", damage to handling equipment and load
spillage.
Type of Vehicle Being Serviced and Grade
Grade of dock areas in conjunction with types of vehicles
being serviced should be considered. An inclined dock may
necessitate a projected dock area to prevent damage to
building walls from oncoming vehicles. Specialized
vehicles such as refrigerated trailers may require longer
Dock Leveler lips, as may trucks with extended tailgates.
