LOADING DOCK LEVELERS
**************************************************************************
NOTE: Electro-hydraulic type loading dock levelers,
supplied with electrical power from a building
system, must be equipped with overload protection as
provided by preset main system relief valve in the
manufacturer's power unit, which will prevent
operation of the elevating device when elevating
device is loaded to 125 percent or more of the rated
capacity. Total leveler gross dynamic loads shall
be determined by fork truck weight plus the maximum
rated fork lift carrying capacity plus attachment
handling device weight.
**************************************************************************
Provide permanent loading dock levelers with minimum performance
characteristics based on the following:
a.
Service Period:
(1) Number of shift operations: [1] [2] [3].
(2) Maximum number of trucks per shift opening:
[_____].
(3) Maximum number of days per week: [_____].
b.
Fork Lift Loads:
(1) Design levelers to accommodate [3][4] wheel fork trucks.
(2) Design levelers to handle [_____] gross dynamic load.
(3) Base load leveler design on number of cycles per
loading/unloading operation per truck and of [_____].
Provide loading dock leveler, [electro-hydraulic type with electric motor
and hydraulic pump operating a hydraulic cylinder that adjusts dock leveler
board position] [mechanical type which is manually released at dock leveler
and raises by spring action and is lowered by walk-on of dock operator]
[air powered type with an industrial fan motor operating a
polyvinylchloride air bag that adjusts dock leveler board position]. A
truck restraint system shall be coordinated with the dock leveler via an
interconnect function such that the restraint and dock leveler will engage
with a single push-button, if a powered trailer restraint is selected to
lock truck or trailer into position during loading and for overnight
security. A visual signal shall be incorporated to inform dock operator
and driver of locked or unlocked status. Make provision for maintenance
access to understructure and lifting mechanism. Provide steel tread plate
lip and platform, hinged and supported from beneath by steel framework that
contains lifting, positioning, and lowering assembly. Ensure that platform
surface is flush with surrounding floor surface of loading dock when not in
service. Provide integral positive restraint when leveler is in
maintenance position.
2.1.1
Environmental Requirements
Design, fabricate, and finish loading ramp to permit washing with water and
detergents, and operating in an ambient temperature from minus 17 to plus
43 degrees C 0 to plus 110 degrees F.
