OPERATING INSTRUCTIONS
YARD RAMP WITH MECHANICAL HAND CRANK
YR Series
1) Raise yard ramp 2” above trailer bed height by rotating
the hand crank lever on the landing gear. Yard ramp
must be on a level surface.
2) Back trailer slowly against yard ramp bumpers. Turn
off engine and set emergency brake on truck. Position
wheel chocks (by others) per OSHA requirements to
prevent trailer movement. Attach safety chains on yard
ramp to trailer to provide maximum safety.
3) Using the hand crank, lower yard ramp lip to meet the
bed of the truck. Continue cranking until the wheels or
landing gear raise approximately 2-3” off the ground.
This will allow the ramp to float while loading or
unloading the trailer.
CAUTION: Do not continue to crank wheels up once
an increase in the resistance of the crank is felt.
Damage could result.
4) Load or unload trailer as needed. Adjust yard ramp
height as necessary to maintain 2-3” minimum
clearance between bottom of landing gear and ground.
5) When loading/unloading is completed, raise yard ramp
2” above the trailer bed. Remove safety chains and
chocks and let trailer pull away.
YARD RAMP W/HYDRAULIC HANDPUMP LIFT
& PNEUMATIC TIRES
Series YR-HL, SY and AY
1) Make sure that the hydraulic release valve is closed.
Raise yard ramp 2” above trailer bed height using the
hand pump on the landing gear. Yard ramp must be on
level surface.
2) Back trailer slowly against yard ramp bumpers. Turn

3) Lower the yard ramp to the trailer bed by using the
pressure release. Leave valve open, this will allow the
ramp to float while loading or unloading the trailer.
4) Load or unload trailer as needed.
5) When loading/unloading is completed, close the valve
and raise the yard ramp 2” above the trailer bed.
Remove safety chains and chocks and let trailer pull
away.
YARD RAMP WITH MECHANICAL DOCKLEVELER
YRD-FM Series
1) Raise yard ramp to approximately trailer bed height by
rotating the hand crank lever on the landing gear. Yard
ramp must be on a level surface.
2) Back trailer slowly against yard ramp bumpers. Turn
off engine and set emergency brake on truck. Position
wheel chocks (by others) per OSHA requirements to
prevent trailer movement. Attach safety chains on yard
ramp to trailer to provide maximum safety.
3) Actuate dockleveler with lever. Pull back in one
continuous motion until dockleveler plate is straight up
and leaning back toward the ramp. Push the leveler
forward to cause the plate to fall into the bed of the
trailer. See Edge-o-Dock owner’s manual for adjusting
instructions.
4) Load or unload trailer as needed. The dockleveler will
float with the trailer, lowering as the trailer is being
loaded or raising as the trailer is being unloaded. The
dockleveler is designed to service trailers from 5”
above ramp height to 5” below ramp height.
5) When loading/unloading is complete, unhook chains
and remove chocks. The trailer may now pull away.
This allows the dockleveler to automatically recycle to
its original position.
NOTE:
The Mechanical Dockleveler is designed for a
maximum service range of plus or minus 5”. Actual
service range may be less depending on the equipment
used to load/unload the trailer. Check the owner’s manual
of the forklift, pallet jack, or cart used to verify service
range and clearance.
YARD RAMP WITH HAND PUMP HYDRAULIC
DOCKLEVELER
YRD-PP Series
1) Raise yard ramp to approximately trailer bed height by
rotating the hand crank lever on the landing gear. Yard
ramp must be on a level surface.
2) Back trailer slowly against yard ramp bumpers. Turn
off engine and ste emergency brake on truck. Position
wheel chocks (by others) per OSHA requirements to
prevent trailer movement. Attach safety chains on yard
ramp to trailer to provide maximum safety.
3) Rotate valve on pump clockwise to close the fluid
return valve. Actuate dockleveler with hand pump.
When the dockleveler clears the trailer bed and fully
extends, release the pressure to allow the lip to settle
on the trailer bed.
NOTE:
The Hydraulic Dockleveler is designed for a
maximum service range of plus or minus 5”. Actual
service range may be less depending on the equipment
used to load/unload the trailer. Check the owner’s manual
of the forklift, pallet jack, or cart used to verify service
range.
ROUTINE MAINTENANCE
ALL YARD RAMPS:
1) Inspect structure before each use for any defects. i.e.
broken welds, stress cracks, etc.
2) Grease lift mechanism and hand crank semiannually.
YARD RAMP WITH PNEUMATIC TIRES:
1) Check tires. Inflate to 100 psi.
2) Check oil level for hydraulic pump. Oil should be filled
to within 1/4” of top of reservoir when yard ramp is in
the fully lowered position.
YARD RAMPS WITH DOCKLEVELERS:
1) Lubricate grease fittings on hinges monthly.
2) check oil level for hydraulic pump (hydraulic leveler
only). Oil should be filled to within 1/4” of top of the
reservoir when dockleveler is in the fully lowered
position.
