INSTALLATION

NOTE: McGuire dock levelers are designed with a nominal 1/2 in. (12.7 mm) shimming distance to allow for pit inconsistencies.

1. Determine height of shim stack (K) for each shim location (B) by performing the following: a. Measure leveler frame height distance (A).

b. Measure dock floor-to-pit floor distance (H) at each shim location (B). Write down the dimensions obtained at each location.

c. Subtract distance (A) from distance (H) to obtain the shim height. Repeat for each shim location.

4. Put a 1/4 in. (6.6 mm) thick shim at locations (C)

(under lip keepers/maintenance prop and safety legs). Make sure shims are larger than frame front flat so pyramid or stepped stacking method can be used.

NOTE: A 1/4 in. (6.6 mm) thick shim at locations (C) is used only as a starting point. The final shim stack height will be determined after the dock leveler is lowered into the pit.

The dock leveler is heavy. Use chains and a lifting device with the appropriate lifting capacity and reach. Failure to do so may result in damage to dock leveler and/or serious personal injury or death.

The minimum size of the shim that contacts the leveler frame (i.e., the top shim of each shim stack) must be at least 4-1/2 x 4-1/2 in. (114.3 x 114.3

mm) to support the full width of the frame rail and to provide a shelf for a fillet weld.

Use the thickest shim stock possible for stability and weld penetration purposes. DO NOT use multiple layers of 1/8 in. (3.18 mm) or thinner shim stock.

2. Using the results obtained in step 1, create the individual shim stacks on the pit floor at locations

(B). Build each shim stack (K) using the pyramid method (M) (preferred) or stepped method (N) with the top shim having a minimum size of 4-1/2 x 4-1/2 in. (114.3 x 114.3 mm) and each successive lower shim being larger so the shims can be welded together using a fillet weld. DO

NOT use offset method (P) or straight method (Q).

NOTE: To assist in obtaining an accurate measurement of distance (J), use a string (F) pulled tight across the pit opening, directly over the shim locations.

3. Verify that each shim stack is at the correct height by measuring distance (J) [top of shim stack (K) to dock floor]. Distance (J) must equal the dock leveler height (A).

5. Using an appropriate lifting device connected to the lifting brackets, lower dock leveler into the pit so rear hinge frame angle (G) is tight against rear pit curb angle (E) across full width of the leveler frame.

6. Allow rear of dock leveler to rest on the rear shims while keeping the front of the dock leveler level with the dock floor.

7. Add shims at front shim locations (C) so front of dock leveler will stay level with dock floor when leveler is resting fully on shims.

10. Allow the dock leveler to rest fully on the shim stacks. Make sure the leveler is in the crosstraffic (stored) position with lip resting on lip keepers.

• Pry between the platform and rear hinge frame angle at locations (E) to make sure rear edge of platform is parallel to the rear hinge frame angle (F).

• Gap (D) must exist equally along both sides of leveler so weather seal (if equipped) will not bind during dock leveler operation.

11. Check that a smooth and level transition exists between the dock floor and the dock leveler platform. Add or remove shims as necessary until a smooth transition is obtained.

9. If gap (D) cannot be obtained equally at both sides of leveler, grind or add material at the rear edge of rear hinge frame angle (F) as needed.

12. If leveler cannot be squared and made level as instructed in steps 8 – 10, contact McGuire

Technical Services.

INSTALLATION

DO NOT grind or weld if hydraulic fluid or other flammable liquid is present on the surface to be ground or welded.

DO NOT grind or weld if uncontained hydraulic fluid or other flammable liquid is present. Stray sparks can ignite spills or leaks near the work area.

Always clean up the oil leaks and spills before proceeding with grinding or welding.

Always keep a fire extinguisher of the proper type nearby when grinding or welding.

Failure to follow these instructions may result in serious personal injury or death.

14. Weld front of dock leveler frame (B) to shims located under the keepers, then weld the shims to the front pit curb steel.

Make sure all personnel are outside of the leveler operating zone and stand clear of the platform lip before removing the shipping bands. Failure to do this may result in serious personal injury or death.

15. With the leveler welded in place remove the shipping bands from around the lip and frame.

16. Disconnect lifting device and chains from the lifting brackets.

Always ground welding equipment to the dock leveler frame, NEVER to the platform.

DO NOT weld continuously along the full length of the rear hinge frame angle. This can put unnecessary stress on the leveler components, causing the leveler not to function correctly and shorten the lifespan of the affected components.

NOTE: The illustration on the previous page shows a typical weld pattern. The weld pattern will vary slightly depending on size of dock leveler.

13. With the rear hinge frame angle (F) tight against the rear pit curb angle (G), weld the rear hinge frame angle (F) to the rear pit curb angle (G) using a 3/8 in. (9.5 mm) flare bevel skip weld

— each weld being 6 in. (152 mm) long.

Start at each end with a 6 in. (152 mm) long weld. Space all the other welds out evenly leaving approximately 6 in. (152 mm) space between each weld.

Alternate welding locations to distribute heat.

Welding sequentially from one end to the other may cause warping or distortion.

When activating the leveler, always pull AND hold the platform release ring until the platform is at the full-raised position. Releasing the ring while the platform is still rising may result in damage to the equipment.

17. Pull and hold the release ring (located in recess at rear of platform) until the platform is fully raised. Check for binding as platform rises.

18. Slowly walk out onto the platform to lower the platform. Allow the platform to lower to the cross-traffic position. Check for binding as platform lowers.

19. If binding occurs, reposition leveler and/or add or remove shims as necessary. Raise and lower platform again. If platform still binds, contact

McGuire Technical Services for further instructions.

20. Check that the leveler is flush with the dock floor and that the platform lip contacts both lip keepers evenly.

15

OPERATION

Theory

1 — Lip

2 — Lip Maintenance Prop

3 — Platform

4 — Lip Link

5 — Lip Assist Spring

6 — Hold Down Release Ring

7— Ratchet Pawl

8— Ratchet Bar

9 — Hold down

The MP-series mechanical dock leveler uses large lift springs (18) to apply force to lift arm (17). The lift arm pushes against the underside of the platform (3), rolling on the cam (not pictured) forcing the platform to rise. The force of the spring tension is just enough to lift the weight of the platform and extend lip.

10 — Platform Maintenance Prop

11— Main Base Frame

12 — Safety Leg Assy.

13 — Snubber Spring

14 — Gas Shock

15 — Safety Leg Below Dock

Control

16— Safety Leg Retract Pull Ring

17 — Lift Arm

18 — Lift Springs

The ratchet pawl disengages only when the platform release ring (6) is pulled AND held. Spring tension from pawl spring causes the ratchet pawl to engage the ratchet bar when the release ring is let go.

When activating the leveler, always pull AND hold the platform release ring until the platform is at the full raised position. Releasing the ring while the platform is still rising may result in damage to the equipment.

When the platform rises to approximately 2 – 3 inches

(51 – 76 mm) from its full raised height, the lip snubber spring (13) and a chain pulls the lip link (4) down. This, in conjunction with the lip assist spring

(5), causes the lip linkage to push the lip out and up.

The lip assist spring also helps control the amount of time required for the lip to fully fold.

To actuate the dock leveler platform, the operator pulls and holds the platform release ring (6) located in the recess at the rear of the platform. This causes ratchet pawl (7) to disengage from ratchet bar (8).

With the ratchet pawl disengaged, spring tension from lift springs (18) forces the platform to rise.

To lower the platform, the operator walks out onto the platform. The platform will lower until the extended lip rests on the truck bed. If the lip did not fully extend or there is no truck at the dock, the platform will lower until one of the following conditions occur:

• Lip is resting on lip keepers (cross-traffic position).

• Lip did not fully fold causing the platform to rest on safety legs (below-dock position).

• Lip did not fully fold and safety legs are retracted, causing the platform to rest on the safety stops (full below-dock position).

NOTE: Ratchet pawl (7) and bar (8) are part of the hold-down mechanism (9)

The hold-down ratchet assembly will keep the platform at the desired position until the platform release ring is pulled again.

ADJUSTMENTS

NOTE: Adjusting the tension of lift springs (4) usually requires that the lip assist spring (3) also be adjusted.

If the platform does not rise fully and/or lip does not extend fully, the lift spring tension may be set too low.

If the platform cannot be walked down or is difficult to walk down, the lift spring tension may be set too high.

3. After lift spring adjustment is completed, check operation of the lip.

• If the lip folds before the platform can be walked down, tension of lip assist spring (3) may be set too low.

• If the lip does not fold fully or takes too long to fold, tension of lip assist spring (3) may be set too high.

If the platform does not rise fully on its own, it may be necessary to use an external lifting device. Use a lifting device with the appropriate lifting capacity to safely raise the platform. Make sure to engage and pin the platform maintenance prop after raising the platform. Failure to do this may result in serious personal injury or death.

When using an external lifting device to raise the platform, make sure hold-down mechanism (6) is disengaged. Pull and hold platform release ring during the lifting process to avoid shearing the ratchet pawl and ratchet bar teeth.

1. Raise the platform and engage the platform maintenance prop. Pin the maintenance prop in the service position using attached pin device.

2.

Adjust tension of lift springs (4) as follows:

NOTE: Use 1/2 turn increments when adjusting lift spring bolt (5).Turn clockwise to increase tension and counterclockwise to decrease tension. Check platform operation after each adjustment. Repeat until proper operation is obtained.

• To increase lift spring tension, turn lift spring bolt (5) clockwise.

• To decrease lift spring tension, turn lift spring bolt (5) counterclockwise.

4. Adjust lip assist spring tension as follows:

NOTE: Use two-turn increments when adjusting lip assist spring (3). Check lip operation after each adjustment. Repeat until proper operation is obtained. a. Loosen jam nut (1).

MISCELLANEOUS

NOTE: Refer to illustration for left/right orientation of dock leveler.

The model/serial number decal (A) is located on the right platform joist near the front (lip) of dock leveler.

When you receive your MP-series dock leveler, write down the dock leveler model and serial number in the form provided. This will help ensure safe keeping of the numbers in the event the model/serial number decal (A) becomes lost or damaged.

Also, write down McGuire’s job number, the company that installed the dock leveler, and the original owner’s name. This will all help to identify the specific dock leveler if more information is required.

When ordering, use part numbers and description to help identify the item ordered. Do not use “item” numbers. These are only for locating the position of the parts. Always give dock leveler MODEL NUMBER and/or SERIAL NUMBER.
