Edge of Dock Leveler 20EP66

For specifiers and bid writers. Blank fields (____) require confirmation from the current Bluff cut sheet or approval drawing for the unit as ordered.

A. Manufacturer

1. Design is based on products manufactured by Bluff Manufacturing, 9201 South Freeway, Fort Worth, TX 76140.
2. Type: Loading dock leveler shall be a fully mechanical edge of dock leveler with self-storing operating handle and torsion-spring lift assist.

B. Product Characteristics

1. Product: Mechanical edge of dock leveler — Model 20EP66.
2. Size: 66" usable width (88" overall) with an overall span (dock to truck bed) of 27-3/4". Closed depth 17". Alternate usable widths of 72" and 78" available.
3. Capacity: 20,000 lbs. (25,000 and 30,000 lb. capacities also available).
4. Estimated weight: ____ lbs (approximately 448 lbs; confirm against current approval drawing).

C. Construction

Deck (center section) and front lip shall be 3/8" steel tread/safety plate, ____ minimum yield. Front lip shall project 15" with bumpers projecting 16-3/4" from the dock face. Lip hinge pin (____ diameter / ____ material) shall be supported by hinge tubes with grease fittings. Hinge tube I.D. ____.

D. Operation

A self-storing operating handle activates the deck and lip. The lip extends and engages the truck bed as the handle is worked, and the unit automatically returns to its stored position, parallel to the dock face, when the truck departs.

E. Lift Assist

Torsion-spring counterbalance, factory-set. The leveler raises with moderate operator effort; effort increases with model capacity and is affected by hinge-tube lubrication and spring condition. The spring assembly (EPSA) is a serviceable, replaceable component.

F. Working Range

±5" above and below dock level with gas or propane forklifts; ±3" above and below dock level for electric forklifts, pallet jacks, and all other equipment.

G. Compliance

Leveler and warranty shall meet or exceed the performance requirements of ANSI MH30.2 and CS-202-55 (OSHA / US Dept. of Commerce).

H. Bumpers

Two (2) EPDM bumpers per leveler, included.

1. The driver reverses the vehicle firmly against the dock bumpers.
2. The dock operator confirms the trailer is chocked or restrained against forward creep or unexpected departure.
3. Pull the handle up until the dead bolt hits the bottom of the 2-inch-square tube sleeve.
4. Pull the handle back until the latch mechanism falls into the catch position.
5. Push the handle forward to extend the unit toward the truck bed until the front lip rests fully on the truck floor.
6. Return the handle to its rest position while loading. Make sure the lip overlaps the truck bed by at least 8 inches before forklift entry.

1. Confirm loading is complete and all personnel and equipment have cleared the leveler.
2. Pull the handle up until the dead bolt hits the bottom of the tube sleeve.
3. Pull the handle back until the front lip clears the truck floor.
4. Allow the weight of the leveler to lower the deck into its stored position, parallel to the dock face.

When the leveler is not in use, keep it in the lowered, stored position.

• Cleaning: clear debris from the hinge tube areas with a wire brush.
• Grease: grease the zerk fittings located underneath the deck.
• Spring assembly: check for proper deck float; inspect the spring linkage rod for bending.
• Handle: inspect for bending or cracking — an improperly bent handle can prevent proper latching.
• Latch & latch catch: inspect contact surfaces for wear.
• Structural: check welds, mount plate, anchors, and the 3/8" steel deck for wear or cracking.

Front lip does not extend when the handle is raised:

• Confirm the latch is attached and the notch faces the dock.
• Check the latch assembly for damage or excessive wear.

Handle hits the dock surface when raised:

• Confirm the handle is seated correctly in the holster with the bend facing away from the dock (toward the trailer).
• Inspect the handle for bending or damage.

Leveler will not raise high enough for the latch to catch:

• Check hinge tube clearance — tubes should sit at least 1/8" above the dock surface.
• Inspect the hinge tubes for debris (wood, nails, etc.) that can block rotation.
• Check the handle for damage.

Leveler is difficult to raise and lower:

• Clean debris from the hinge tube areas with a wire brush.
• Grease the hinge tubes thoroughly — insufficient lubrication is the most common cause.

Always specify model number 20EP66 and your unit’s serial number when ordering parts.
